                                 PROXY STATEMENT

                   First sent to Shareholders on July 9, 1999

     The  enclosed  proxy is  solicited  by the Board of  Directors of Detection
Systems,  Inc. (the  "Company") for use at the Annual Meeting of Shareholders to
be held August 12, 1999 at 2 p.m., and at any adjournments  thereof.  The record

this  meeting  is the close of  business  on June 30,  1999,  at which  time the
Company had  outstanding  6,345,495  shares of Common  Stock.  Shareholders  are
entitled to one vote for each share owned.

     Directors are elected by a plurality of votes cast. The affirmative vote of
holders of a majority of outstanding shares is required to approve the amendment
to the  Company's  1997 Stock Option Plan,  to adopt the  Non-Employee  Director
Stock Option Plan and ratify options granted  pursuant to this Plan and to amend

meeting but will not be considered to have been voted. All shares represented by
a proxy will be voted in accordance with the specifications  made thereon by the
shareholder  and, if no specification is made, will be voted for the election as

proposal  to amend the  Company's  1997 Stock  Option Plan and  ratification  of
options  granted  pursuant to this Plan,  for the  adoption of the  Non-Employee
Director  Stock Option Plan,  for the amendment of the Company's  Certificate of
Incorporation    and   for   the    ratification    of   the    appointment   of
PricewaterhouseCoopers LLP as independent auditors.

     Shareholders  can  ensure  that their  shares  are voted at the  meeting by
signing and dating the enclosed proxy and returning it in the envelope provided.
Sending in a signed  proxy will not affect a  shareholder's  right to attend the
meeting and vote in person.  A shareholder may revoke a proxy at any time before
it is voted by notifying the Company's Transfer Agent, American Stock Transfer &
Trust Co., 40 Wall Street,  New York, NY 10005, in writing,  or by executing and
delivering to the Secretary of the Company a subsequent proxy.


                              ELECTION OF DIRECTORS

     At the annual  meeting,  five directors,  constituting  the entire Board of
Directors, are to be elected to hold office for the ensuing year and until their
successors are elected and  qualified.  The Board of Directors has nominated the
following persons for election as directors: Donald R. Adair, Mortimer B. Fuller
III, Karl H.  Kostusiak,  David B. Lederer and Edward C. McIrvine.  Each of them
has consented to be named in this Proxy  Statement  and to serve if elected.  If
for any  reason any of these  nominees  become  unavailable  for  election,  the
proxies may exercise discretionary authority to vote for substitutes proposed by
the Board of Directors.

     Messrs.  Kostusiak  and Lederer  have been  President  and  Executive  Vice
President of the Company since it was formed in 1968.  Effective  April 1, 1998,
Mr. Lederer  reduced his  employment to half time. In connection  with this, Mr.
Lederer's title was changed to Vice President,  Business Development.  Mr. Adair
is the  principal  of Adair  Law Firm in  Rochester,  New  York.  Mr.  Fuller is
Chairman and Chief Executive Officer of Genesee and Wyoming Industries,  Inc., a
holding company in Greenwich,  Connecticut, which owns and operates regional and
short line freight railroads and provides rail related services to railroads and
shippers. Dr. McIrvine is self-employed as a research and development management
consultant.  Until 1991,  he served as Dean of the  College of Graphic  Arts and
Photography at the Rochester Institute of Technology.

     During the fiscal year ended March 31, 1999,  the Board of  Directors  held
ten  meetings.  The Board of  Directors  has an audit  committee  consisting  of
Messrs. Adair, Fuller and McIrvine.  This committee,  which met six times during
the last fiscal year,  reviews  reports of the  Company's  financial  condition,
financial  controls  and  accounting  procedures.  In addition,  this  Committee
approves and oversees services performed by the Company's  independent  auditors
and provides the independent  auditors direct access to the non-employee members
of the Board of Directors.

     The Board of Directors  also has a  compensation  committee  consisting  of
Messrs.  Adair,  Fuller and McIrvine.  This committee,  which is responsible for
establishing  general  compensation  policies,  establishing  and  administering
compensation  plans and programs in which officers  participate and establishing
the specific compensation arrangements for the Company's executive officers, met
four times during the last fiscal year. Messrs.  Adair, Fuller and McIrvine also
serve on the stock  option  committee.  This  committee,  which met seven  times
during the year, is responsible for granting  options  pursuant to the Company's
Stock Option Plans. There is no nominating  committee of the Board of Directors.
All of the Directors  attended more than 75% of the aggregate of all meetings of
the Board of Directors and the committees on which they served during the fiscal
year.

     During  fiscal 1999,  Directors  who are not  employees of the Company were
paid an annual fee of $12,000 as well as $1,000  plus travel  expenses,  if any,
for each day on which they attended Board meetings.  Directors received $500 for
Board meetings held by teleconference.  Messrs Adair and McIrvine were each paid
an annual  fee of $8,000  for their  service as  Chairpersons  of the  Company's
Compensation  and Audit Committees of the Board of Directors.  In addition,  the
non-employee  directors  were each  awarded a 2,000 share stock option under the
Company's  Non-Employee  Director  Stock  Option  Plan,  subject to adoption and
ratification by the  shareholders  at the August 12, 1999 annual  meeting.  [See
"Non-Employee   Director   Stock  Option   Plan."].   There  was  no  additional
compensation for attendance of committee meetings.

     The Board of Directors recommends a vote FOR the election of Messrs. Adair,
Fuller, Kostusiak, Lederer and McIrvine as Directors of the Company for the 2000
fiscal year.  Proxies will be so voted  unless  shareholders  specify a contrary
choice in their proxies.

             PROPOSAL TO AMEND THE COMPANY'S 1997 STOCK OPTION PLAN


     On February 10, 1999, the Company's Board of Directors approved, subject to
approval by the  stockholders,  an amendment to the Company's  1997 Stock Option
Plan  (the  "Plan"),  a copy of which is set forth as  Exhibit  A to this  Proxy
Statement,  to increase the number of shares  authorized  for options  under the
Plan from 250,000 to 500,000 shares.  The Plan, as amended,  provides that stock
options for the  purchase of up to 500,000  shares of common stock may be issued
to key employees or nonemployees of the Company and its subsidiaries pursuant to
the exercise of stock options.  This Plan was  originally  adopted on August 20,
1997.

1997 Amended Stock Option Plan:

     The  purpose  of  the  Plan  is  to  enable   eligible  key  employees  and
nonemployees  of the Company and its  subsidiaries  to purchase shares of Common
Stock of the Company by means of stock options. Through the use of such options,
the Company  expects to be able to attract and retain the best available  talent
and to encourage the highest level of performance of its key personnel.

     If the  proposed  amendment  to the Plan is  approved,  a total of  500,000
shares  of  Common  Stock of the  Company,  par value  $.05 per  share,  will be
available for options under the Plan (with an appropriate  change in that number
in the event of a stock split,  stock  dividend or other change in the Company's
Common  Stock).  These shares may be either  authorized  and unissued  shares or
treasury shares.  Options may be either  incentive stock options,  as defined in
Section 422 of the Internal  Revenue Code ("the Code"),  or options which do not
meet the  requirements  of that  section  (nonqualified  options).  If an option
expires,  terminates  or is canceled  without being  exercised,  new options may
thereafter be granted  covering the same shares.  No stock option may be granted
more than ten years after the effective date of the Plan.

     The Plan is  administered  by the  Stock  Option  Committee  ("Committee"),
consisting  of not fewer  than  three  members  elected  from among the Board of
Directors of the Company.  The Committee determines who shall be granted options
under the Plan,  the number of shares to be awarded and the terms of each award,
and  interprets  the provisions of the Plan. The Board of Directors may amend or
terminate the Plan, without the approval of the shareholders, except that it may
not,  without  such  approval,  materially  increase  the  benefits  accruing to
participants  under the Plan,  increase the number of shares subject to options,
change the minimum  exercise  price,  change the class of employees  eligible to
receive  awards or extend  the  period  during  which  awards  may be granted or
exercised.

     The  Plan  provides  that  options  may  be  granted  to key  employees  or
nonemployees of the Company and its  subsidiaries.  However,  options may not be
granted to members of the  Committee  or to  directors  who are not  officers or
employees  of the Company or its  subsidiaries.  Code Section  162(m)  presently
imposes  a limit  on the  grant  of  incentive  options.  In  order  to meet the
requirements of Code,  which limits the Company's tax deduction for compensation
paid to certain  officers to $1 million per year, a limit of 100,000  shares has
been placed in the  aggregate  number of options  that may be awarded to any one
employee  under  the Plan.  It  imposes  no limit on the  grant of  nonqualified
options.

     The purchase price for each incentive  option may not be less than the fair
market  value of the stock at the time the option is  granted.  If an  incentive
option is  granted to an  employee  who,  at the time of the  grant,  owns stock
possessing  more than 10% of the voting power of all stock of the  Company,  the
purchase  price  must be at least  110% of the fair  market  value of the  stock
subject to the option.

     An  option  shall  be  exercised   upon  written   notice  to  the  Company
accompanied: (a) by payment in full for the shares being acquired, which payment
shall be made in cash,  check or wire  transfer;  (b) by  delivery  of shares of
Common Stock of the Company registered in the name of the optionee,  endorsed in
blank,  the value of which will be deemed  equal to the closing  market price of
such shares on the date of exercise;  or (c) by a so-called  "cashless exercise"
transaction at the  discretion of the  Committee,  that affords the optionee the
opportunity  to  sell  immediately  some  or all of the  shares  underlying  the
exercise  portion of the option in order to generate  sufficient cash to pay the
option exercise price and/or to satisfy  withholding tax obligations  related to
the option.

     Each option will have a maximum term of ten years, or such lesser period as
the Committee specifies,  except that an incentive option granted to an employee
who, at the time of the grant, owns stock possessing more than 10% of the voting
power of all stock of the Company  will have a term not in excess of five years.
Options are  exercisable at such time or times and under such  conditions as may
be imposed by the Committee and set forth in an option agreement.

     The  benefits or amounts  that will be received or  allocated in the future
under the Plan are not  determinable.  The following table provides  information
regarding  options  granted  under the Company's  1997 and 1992  Restated  Stock
Option Plan in fiscal 1999.

*  Options  were  granted  at  prices  ranging  from  $8.625 to $10.00 and  with
   expiration dates ranging from 6/1/03 and 2/9/04.

     Under  present law, the grant and exercise of stock  options under the Plan
will be treated for federal tax purposes as follows: When an incentive option is
granted to an employee,  there is no tax  consequence  to either the employee or
the Company.  When an employee  exercises an incentive option,  there will be no
regular income tax  consequences to either the employee or the Company,  but the
spread  between the option price and the common stock's fair market value on the
date of exercise is taken into  consideration  for purposes of  determining  the
employee's liability,  if any, for the alternative minimum tax. When an employee
sells stock  purchased  by the exercise of a stock  option,  the tax on any gain
will be long-term capital gain if the employee holds the stock for more than one
year and if the sale  occurs at least two years  after the date the  option  was
granted.  An earlier sale will result in the spread between the option price and
the fair market price value of the shares on the date of exercise being taxed at
ordinary  income  rates.  Any  additional  gain above fair  market  value on the
exercise date will be taxed as short-term or long-term capital gain depending on
the holding period.

     When a  nonqualified  option is  granted  to an  employee,  there is no tax
consequence to either the employee or the Company.  When an employee exercises a
nonqualified  option,  the difference between the value of the stock on the date
of exercise and the option price will be ordinary  income to the employee.  When
the employee sells the stock purchased by the  nonqualified  option,  the tax on
any gain will be long-term capital gain if the employee holds the stock for more
than one year.  An earlier  sale will cause any gain to be taxed as a short-term
capital gain. At the time an employee recognizes ordinary income, either through
the exercise of a  nonqualified  option or the  disqualifying  disposition of an
incentive option,  the Company will be entitled to take a tax deduction equal to
the amount of income recognized by the employee.

     At June 7, 1999,  there were 242,600  outstanding  options and 7,400 shares
available  for grant under the 1997 Stock  Option  Plan and 374,075  outstanding
options and 925 shares  available for grant under the 1992 Restated Stock Option
Plan.  The high,  low and  closing  bids on that date for the  Company's  Common
Stock,  as reported by The Nasdaq Stock  Market,  were $8.50,  $8.375 and $8.50,
respectively.

     The Board of Directors  believes that an amendment to the 1997 Stock Option
Plan is in the best interest of the Company and its  shareholders and recommends
that  shareholders  vote in favor  of this  proposal.  Proxies  will be so voted
unless shareholders specify a contrary choice in their proxies.


    PROPOSAL TO ADOPT THE COMPANY'S NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

     On September 4, 1998, the Company's Board of Directors adopted,  subject to
approval by the stockholders,  the Company's  Non-Employee Director stock Option
Plan  (the  "Plan"),  a copy of which is set forth as  Exhibit  B to this  Proxy
Statement. The Plan provides that stock options for the purchase of up to 50,000
shares of common  stock may be issued to  non-employee  directors of the Company
pursuant to the exercise of stock options.

Non-Employee Director Stock Option Plan:

     The purpose of the Plan is to enable the Company's  non-employee  directors
of the  Company to  purchase  shares of Common  Stock of the Company by means of
stock options.  Through the use of such options,  the Company expects to be able
to attract and retain qualified directors for its Board.

     A total of 50,000 shares of Common Stock of the Company, par value $.05 per
share, will be available for options under the Plan (with an appropriate  change
in that number in the event of a stock split,  stock dividend or other change in
the Company's Common Stock).  These shares may be either authorized and unissued
shares or  treasury  shares.  If an option  expires,  terminates  or is canceled
without being exercised, new options may thereafter be granted covering the same
shares.  Options awarded under the Plan are  nonqualified  options since they do
not meet the  requirements  as defined in Section  422 of the  Internal  Revenue
Code.  No stock  option may be granted  more than ten years after the  effective
date of the Plan.

     The Plan is  administered by the Company's Board of Directors (the "Board")
who shall,  subject to the provisions of the Plan, grant options under the Plan.
The Board of Directors may amend or terminate the Plan,  without the approval of
the  shareholders,  except that it may not,  without such  approval,  materially
increase  the benefits  accruing to  participants  under the Plan,  increase the
number of shares subject to options,  change the minimum exercise price,  change
the class of employees  eligible to receive  awards or extend the period  during
which awards may be granted or exercised.

     The Plan provides that options may be granted to non-employee  directors of
the Company.  Options may not be granted to members of the Board or to directors
who are officers or employees of the Company.  The Plan places no  limitation on
the number of shares  with  respect to which  options  may be granted to any one
individual.  The  purchase  price for each  option may not be less than the fair
market value of the stock at the time the option is granted.

     An option shall be exercised upon written notice to the Company accompanied
by: (i) cash,  check or wire transfer  payable in United States  currency to the
order of the  Company  for an amount  equal to the  option  price for the shares
being  purchased,  or (ii)  shares of the  Company's  Common  Stock owned by the
optionee duly  endorsed to the order of the Company,  the value of which will be
deemed equal to the closing market price of such shares on the date of exercise,
or (iii) any combination of the foregoing,  together with such other instruments
or  agreements  duly signed by the optionee as in the opinion of counsel for the
Company may be  necessary  or advisable in order that the issuance of the shares
comply with applicable  rules and regulations  under the Securities Act of 1933,
any  appropriate  state  securities  laws or any  applicable  requirement of any
national  stock  exchange or quotation  or market  system on which the shares of
Common Stock may then be traded.

     Options  granted  under the Plan  shall have a term of up to ten years from
the date of grant,  provided,  however,  that each  option  shall  automatically
terminate  at the close of  business on the 210th day after the day on which the
non-employee  director ceases to be a director of the Company and if that day is
not a regular business day at the Company's  principal office, then at the close
of business of the next such regular  business day.  Options are  exercisable at
such time or times and under such  conditions as may be imposed by the Committee
and set forth in an option agreement.

     The  benefits or amounts  that will be received or  allocated in the future
under the Plan are not  determinable.  The following table provides  information
regarding options granted under the Company's Non-Employee Director Stock Option
Plan in fiscal 1999 (subject to shareholder approval):

</TABLE>

* Options were granted at a price of $8.6875 per share with an  expiration  date
of 9/3/08.

     Options  awarded under this Plan are  nonqualified  options and are treated
for tax  purposes as described  above under the 1997  Amended  Stock Option Plan
description.  At June 7, 1999, there were 6,000  outstanding  options and 44,000
shares  available  for grant under the Plan.  The high,  low and closing bids on
that date for the  Company's  Common  Stock,  as  reported  by The Nasdaq  Stock
Market, were $8.50, $8.375 and $8.50, respectively.

     The  Board  of  Directors  believes  that  the  adoption  of the  Company's
Non-Employee  Director stock Option Plan and the ratification of options granted
pursuant  to  the  Plan  are  in the  best  interest  of  the  Company  and  its
shareholders  and recommends that  shareholders  vote in favor of this proposal.
Proxies will be so voted unless shareholders  specify a contrary choice in their
proxies.



          PROPOSAL TO AMEND THE COMPANY'S CERTIFICATE OF INCORPORATION

     On June 29, 1999, the Board of Directors  approved,  subject to shareholder
approval, an amendment of the Company's Certificate of Incorporation to  achieve
consistency with recent changes in New York Business Corporation Law  concerning
approval of loans to directors.  Effective February 22, 1998, Section 714 of the
New  York  Business  Corporation  Law was  amended so as to  provide  that,  for
corporations formed thereafter, a corporation may lend money to or guarantee the
obligation  of a  director  of  the  corporation,  provided  that  the  Board of
Directors "determines that the loan or guarantee benefits  the  corporation  and
either approves the  specific  loan or  guarantee or a general  plan authorizing
loans and guarantees."  Previously  Section 714  provided  that any  loan to, or
guarantee  of  the  debt  of,  a  director  would  have  to  be  approved by the
shareholders of the corporation, and that requirement continues to apply for New
York corporations  formed  prior  to  February 22, 1998  (including the Company)
unless  the  corporation's  Certificate  of  Incorporation  is amended to permit
approval of such loans by the Board of Directors. The amendment of the Company's
Certificate of Incorporation which the Company's Board of Directors has approved
authorizes the making of such loans or  guarantees  by the Board of Directors in
accordance  with the  new  provisions of Section  714.  A copy  of the  proposed
Certificate of Amendment is attached as Exhibit C to this Proxy Statement.

     From time to time the Board of  Directors  has  encountered  situations  in
which loans to officers and other key  employees,  including  those who are also
directors,  would be an appropriate way of assisting those persons in connection
with the achievement of various Company goals.  Circumstances that might warrant
the extension of a loan  include,  but are not limited to,  assistance  with the
acquisition of Company stock under stock option or stock bonus plans, assistance
with related tax expenses, and assistance with significant moving expenses if an
executive is requested to relocate. If approved,  the amendment would permit the
Board of Directors to authorize a loan to any director,  provided that the Board
"determines  that the loan or  guarantee  benefits  the  corporation  and either
approves the specific loan or guarantee or a general plan authorizing  loans and
guarantees."  The ability to have the Board authorize such loans will facilitate
taking prompt action when necessary.  The Board of Directors believes that it is
appropriate to amend the Company's  Certificate of Incorporation as proposed, so
that the Company's  required  approval  procedures  for such loans or guarantees
will  be  consistent  with  the  procedures  now  authorized  by  the  New  York
Legislature for all New York corporations formed since February 22, 1998.

     The Board of Directors  believes that the amendment of the  Certificate  of
Incorporation  as  proposed  is in the  best  interest  of the  Company  and its
shareholders  and recommends that  shareholders  vote in favor of this proposal.
Proxies will be so voted unless shareholders  specify a contrary choice in their
proxies.



                     RATIFICATION OF APPOINTMENT OF AUDITORS

     The  Board of  Directors  has  recommended  that  shareholders  ratify  the
appointment of  PricewaterhouseCoopers  LLP as the  independent  auditors of the
Company for the fiscal year ending March 31, 2000.  They have served the Company
as independent auditors since 1968. Representatives of that firm will be present
at the meeting,  will have an  opportunity to make a statement if they desire to
do  so  and  will  be  available  to  respond  to  appropriate   questions  from
shareholders.

     The  Board  of  Directors  recommends  a vote FOR the  ratification  of the
appointment of  PricewaterhouseCoopers  LLP as the  independent  auditors of the
Company for the 2000 fiscal year.  Proxies will be so voted unless  shareholders
specify a contrary choice in their proxies.



                        COMPENSATION COMMITTEE REPORT ON
                             EXECUTIVE COMPENSATION

     The Compensation Committee of the Board of Directors is responsible for (a)
establishing general compensation  policies,  (b) establishing and administering
compensation   plans  and  programs  in  which  officers   participate  and  (c)
establishing the specific compensation  arrangements for the Company's executive
officers. The members of this Committee also serve on the Stock Option Committee
under the Company's 1992 and 1997 Stock Option Plans.

Committee Objectives Concerning Executive Officers:

     The Compensation Committee has sought four key objectives for the Company's
executive  compensation plans,  programs and arrangements.  These are to (a) tie
executive  compensation to the Company's  financial  performance,  (b) encourage
equity   ownership  in  the  Company  by  all  executives,   (c)  tie  executive
compensation   programs  to  the  achievement  of  long-term  company  strategic
objectives, and (d) provide overall executive compensation that will attract and
retain an effective  management  team. The Committee  recognizes  that different
plans or  arrangements  will  serve one or more of those  objectives  in varying
degrees,  that the relative significance of the stated objectives may shift from
time to time, and that new objectives may arise and become important.

     During  fiscal year 1999 and  subsequently,  two  additional  factors  have
affected the Committee's determinations:  (1) the Company's continuing expansion
activities and a need to motivate management  personnel at various places around
the world; and (2) the need to continue  working toward long-term  succession of
management.   Various  changes  have  been  made  or  proposed  in  compensation
arrangements during this period to respond to these issues.

Employment Agreements:

     In 1988, the Company  entered into  five-year  employment  agreements  with
Messrs.  Kostusiak and Lederer.  Each year thereafter,  the agreements have been
re-examined,  reviewed and revised as appropriate and then re-executed for a new
five-year period.  Besides the comments made in this Committee report, a summary
of the agreements is contained under "Executive Agreements" below.

Tying Compensation to the Company's Financial Performance:

     Among other goals,  the employment  agreements  seek to create a strong tie
between the  compensation  of Messrs.  Kostusiak  and Lederer and the  Company's
financial performance.  Mr. Kostusiak's agreement pursues this goal by providing
for an opportunity for an annual cash bonus based on pre-tax profits. This bonus
program was also made  available to other full time  executive  officers and key
personnel of the Company  with the goal of aligning  their  compensation  to the
Company's  financial  performance.  Since his  reduction to part-time  status in
April 1998,  Mr.  Lederer is no longer  eligible for payment under this program.
During  fiscal 1998,  in response to the Company's  growth,  the pre-tax  profit
threshold  was changed  from a fixed  dollar  amount  ($2,000,000)  to 4% of net
sales.  This bonus is intended to provide  incentives for managing the Company's
financial  performance toward having pre-tax profits  significantly exceed 4% of
sales.

     During fiscal 1998, the Committee  eliminated a previously used stock bonus
plan for executives and reverted to the use of stock options.  In that year, for
the first time since 1987, a stock option was granted to Mr.  Kostusiak  for the
purchase  of 20,000  shares of stock at a price of $14.75 per share.  No options
were granted to Mr. Kostusiak in fiscal 1999.

     Executive  officers who do not  participate  in the  Company's  annual cash
bonus program participate in the Company's general profit sharing plan, which is
available  to most U.S.  based  employees.  This plan,  which was revised at the
beginning of fiscal  1999,  provides a quarterly  distribution  of 4% of pre-tax
profits in excess of 4% of net sales. Mr. Lederer was the only executive officer
eligible for payment under the general profit sharing plan in fiscal 1999.

         The  Committee  believes that the bonus  provisions  of the  employment
agreements  generally  functioned  as intended  during the past three years.  In
particular, Mr. Kostusiak's bonus compensation was as follows:

</TABLE>

Equity  Ownership by Management:

     Since the Company's  founding in 1968,  Messrs.  Kostusiak and Lederer have
each owned a substantial  number of shares of the Company's  Common Stock.  Over
the years since then other officers have been granted  opportunities  to acquire
stock  through  stock  options and bonus  stock  programs.  Under the  Company's
current  stock  option plan,  options are granted at exercise  prices that equal
fair  market  value of the  option  shares on the date of grant,  and the option
rights vest incrementally as per the terms of the grants. From time to time, the
Stock Option Committee  grants options under the plan to Company  executives and
other key employees and, as noted above, in November 1997, a 20,000-share option
was  granted  to  Mr.  Kostusiak.   The  Committee  believes  that  the  options
themselves,  even when  unexercised,  provide  incentives  for key  personnel to
improve shareholder value, since only then will the options become valuable.

Achievement of Long-Term Company Objectives:

     The Committee  believes that having executive  officers who own substantial
equity  positions in the Company  provides a considerable  incentive for them to
pursue the Company's long-term strategic objectives.

     Additionally, in order to serve long-term objectives and build a succession
plan for  senior  management,  the  Company  has  made  commitments  to  Messrs.
Kostusiak  and Lederer to pay  retirement  benefits (See  Retirement  Benefits).
Also, the Committee increased Mr. Kostusiak's base salary during fiscal 1999 and
secured  an  extended   non-competition   commitment  from  him  (See  Executive
Agreements).

     As part of the continuing  development of a long-term  succession plan, the
Committee  continues to consider  implementation  of certain  trusts for holding
Company assets that are intended to fund deferred  compensation  obligations and
other benefit  commitments.  While those assets might  continue to be subject to
the claims of Company  creditors,  the use of such trusts could become a helpful
part of the overall succession plan.

Attracting and Retaining Management:

     The  Committee  believes  that the  Company  is  attracting  and  retaining
effective  management  personnel  and that the  Company's  approach to executive
compensation  continues to be  appropriate  for achieving  that  objective.  The
Committee  anticipates  that,  from  time to time,  independent  studies  of the
Company's  overall  executive  compensation  and  other  investigations  will be
conducted so as to test the Company's compensation approach against compensation
programs offered by others.


                                                     COMPENSATION COMMITTEE

                          Donald R. Adair, Chairperson
                             Mortimer B. Fuller, III
                               Edward C. McIrvine



                              EXECUTIVE AGREEMENTS

     The Company has  employment  agreements  through  July 2004 with two of its
executive officers,  Messrs. Kostusiak and Lederer (the "Executive Agreements').
Effective April 1998, Mr.  Lederer's  employment  commitment was reduced to half
time.

     The  Executive  Agreements  provide for  severance  benefits  under certain
circumstances.  The terms "change in control," "cause" and "disability" are used
in the  following  description  as  defined  in the  Executive  Agreements.  The
Executive  Agreements  terminate the  executive's  employment  upon his death or
permanent  disability and, in those cases,  provide for disability  income to be
paid  during  disability  and  a  retirement  wage  benefit  to be  paid  during
retirement years and to any surviving spouse (see Retirement Benefits).

     Under the Executive  Agreements,  if the Company terminates the executive's
employment without cause, the Company will continue compensation and benefits to
the executive for the then remaining  balance of the term of employment or for a
period of three years from the date of  termination,  whichever  is longer.  The
continuation of compensation  and benefits  includes the executive's base salary
plus participation in all applicable executive incentive  compensation plans and
fringe benefit packages. The Company thereafter will pay non-competition fees as
described below and retirement benefits as described under Retirement Benefits.

     If the Company terminates Mr.  Kostusiak's or Mr. Lederer's  employment for
cause, each will receive  compensation and benefits for the remaining balance of
the  term of  employment  or for a  period  of  three  years  from  the  date of
termination,  whichever  is  longer,  plus  non-competition  fees and  benefits,
retirement  benefits,  and  possible  disability  benefits,  provided  that this
compensation  is reduced by any monetary  damage  suffered by the Company due to
the cause.

     Mr.  Kostusiak's  agreement  provides  that he will  not  compete  with the
Company so long as the Company either retains his full-time services or pays him
an annual non-competition fee of $150,000 (to be increased annually based on the
Consumer Price Index) plus benefits to the date of his  retirement  (now set for
the January 1 after his 69th birthday) and then pays the retirement benefit.

     If a "change in control" occurs, as defined in the Executive Agreements and
Mr. Kostusiak's or Mr. Lederer's  employment is terminated by the Company or the
executive  within six months after the Company or the executive has given notice
for the six-month  period to start running,  the executive  would be entitled to
receive (a) the base salary  through the  termination  date, as in effect at the
time of  termination or at the time the change in control  occurs,  whichever is
higher,  plus any bonus  which has been  earned but not yet paid,  (b) an amount
equal to three times the highest total cash compensation  (including base salary
and bonuses) paid to him in any of the Company's  preceding  three fiscal years,
(c) an amount  equal to the total  amounts  that would be expended  for benefits
over  the  next  three  years  if he  had  continued  as  an  employee,  (d)  an
acceleration  of the right to  exercise  all  rights or options he then holds to
acquire the  Company's  Common  Stock and he may either  exercise the rights and
options or elect to receive cash for the aggregate  spread  between the exercise
price and the then market value for the stock,  (e)  assignment of all rights in
life insurance policies then held by the Company on his life (after repayment by
the Company of any loans thereon taken by the Company),  (f)  reimbursement  for
any  amount of excise  taxes he might  have to pay on his  receipt  of items (a)
through (e)  sufficient  so that the Company  will bear all direct and  indirect
costs of any such excise  taxes,  and (g) that upon  termination,  the executive
becomes obligated to provide up to 8 days of consulting services per year to the
Company and not to compete with the Company,  and the Company becomes  obligated
to pay  $150,000  per year and  benefits  to the  executive  for the  consulting
services  and  non-competition  until  the  executive's   retirement  date.  The
Agreements also provide that, upon a change in control,  the initial  retirement
wage  commitment  will  become 60% of the base  salary for the last year of full
time  employment  and the Company shall place in trust either cash or an annuity
policy that will  sufficiently  fund the retirement  benefits  called for by the
Agreement.



                               RETIREMENT BENEFITS

     In April 1996,  the Company  approved the addition of a retirement  benefit
plan for Messrs. Kostusiak and Lederer (each, an "Executive") in their Executive
Agreements.  Under the terms of the current  Executive  Agreements,  the Company
will  pay  each  Executive  retirement  benefits  for his  lifetime  and for his
spouse's lifetime, if his spouse survives him.

     For each Executive,  assuming he retires at the end of the calendar year in
which he turns 69 years of age,  benefits would be as follows:  (a) a retirement
wage benefit  initially equal to 30% of his base salary for the last year of his
full time  employment,  increased  each year  thereafter  by any increase in the
Consumer  Price Index  (except that the wage benefit for his spouse shall be 75%
of that amount after  Executive's  death);  (b) continuation of Executive's full
health  insurance  or similar  benefit for  Executive  and his  spouse;  and (c)
continuation of any other benefit programs that provide continuation pursuant to
their terms,  limited in  individual  benefit cost to 60% of the maximum  annual
cost of such benefit in any year prior to retirement,  plus Consumer Price Index
increases.

     Based on a 5%  compounded  annual  increase in the base  compensation,  and
assuming  each  Executive  will retire at age 69, the estimated  initial  annual
benefit that would be payable to Messrs. Kostusiak and Lederer under the pension
plan  provision  in their  Executive  Agreements  would be $151,587 and $94,029,
respectively.

     The  Executive   Agreements  further  provide  that:  (a)  the  payment  of
retirement  benefits may be terminated if a court  determines that the Executive
has violated the  non-competition  provisions of his Executive Agreement and (b)
the Company will  purchase and maintain  life  insurance  sufficient to fund the
estimated  benefits for the spouse (any excess policy  proceeds to be available,
if agreed,  to purchase shares of the Company's Common Stock held in Executive's
estate) and the policy or policies  of such  insurance  shall be held in a trust
designed for this purpose.

     The  Agreements  also provide that,  upon a change in control,  the initial
retirement  wage commitment will become 60% of the base salary for the last year
of full time  employment  and the Company shall place in trust either cash or an
annuity policy that will sufficiently fund the retirement benefits called for by
the   Agreement.   Also,  if  the  Company   terminates   the   consulting   and
non-competition payments after a change in control, the provisions comparable to
those  described in the first  sentence of the last paragraph  under  "Executive
Agreements"  above  become  applicable  based  on  non-competition  and  minimum
consulting fees then being paid annually to the executive.



                        COMPENSATION COMMITTEE INTERLOCKS
                            AND INSIDER PARTICIPATION

     The members of the  Compensation  Committee of the Board of  Directors  are
Messrs.   Adair,   Fuller  and  McIrvine.   None  of  these  directors  received
compensation  from the  Company  except  for their  fees and stock  options as a
director of the Company.


                            EXPENSES OF SOLICITATION

     The cost of the  solicitation  of proxies will be borne by the Company.  In
addition to  solicitation by mail,  employees of the Company may,  without extra
remuneration,  solicit  proxies  personally,  or by telephone or facsimile.  The
Company has retained  Kissel-Blake,  Inc. to aid in the  solicitation of proxies
for shares held of record by banks,  brokers and other custodians,  nominees and
fiduciaries.  The Company will pay  Kissel-Blake  an anticipated  fee of $5,000,
plus expenses,  for these services,  and will also reimburse such record holders
for their expenses in forwarding  proxies and proxy  soliciting  material to the
beneficial owners of the shares held by them.

                             DETECTION SYSTEMS, INC.
                         1997 AMENDED STOCK OPTION PLAN


1.       PURPOSE

       The purpose of the Detection  Systems,  Inc.  ("the  Company") 1997 Stock
Option Plan ("the Plan") is to enable eligible key employees and nonemployees of
the  Company and its  subsidiaries  to  purchase  shares of Common  Stock of the
Company by means of  incentive  stock  options and  nonqualified  stock  options
(collectively  referred to as "options").  Through the use of such options,  the
Company  expects to be able to attract and retain the best available  talent and
to encourage the highest level of performance of its key personnel.

2.     ADMINISTRATION

       The  Plan  shall  be  administered  by  a  Stock  Option  Committee  (the
"Committee")  consisting of not fewer than three members  appointed by the Board
of Directors of the Company,  each of whom, to the extent  feasible,  shall be a
director  meeting the  definition as a  "non-employee  director" and an "outside
director,"  respectively,  under regulations  promulgated under Section 16(b) of
the Securities Exchange Act of 1934, as amended (the Exchange Act"), and Section
162(m) of the  Internal  Revenue  Code of 1986,  as  amended  (the  "Code"),  or
comparable  provisions as in effect from time to time.  The Board shall fill any
vacancy on the Committee.

       Subject to the  provisions of the Plan,  the Committee  shall possess the
authority,  in its  discretion,  (a) to determine  from among those  persons who
perform services to the Company to whom, and the time or times at which, options
will be awarded, the number of shares included in the option and any other terms
and  conditions  that may apply to such  option;  (b) to  determine  whether the
options shall be incentive or nonqualified  options;  (c) to interpret the Plan;
(d) to make and amend rules and regulations  relating thereto;  (e) to prescribe
the form and  conditions  of the  option  agreements;  and (f) to make all other
determinations  necessary or advisable for the  administration  of the Plan. The
Committee's determinations shall be conclusive and binding upon the Company, the
participants and all other persons.

3.     ELIGIBILITY

       Options  may be  awarded  under  the Plan only to key  employees  and key
nonemployees  of the  Company  and its  subsidiaries  (which  shall  include all
corporations of which at least fifty percent of the voting stock is owned by the
Company  directly or through one or more  corporations at least fifty percent of
the  voting  stock of which is so owned).  Notwithstanding  the  foregoing,  any
director  who  is not an  officer  or  employee  of  the  Company  or one of its
subsidiaries shall not be eligible to participate in this Plan.

 4.    SHARES AVAILABLE

     An  aggregate  of 500,000  shares of the  Common  Stock (par value $.05 per
share) of the Company  (subject to  substitution  or  adjustment  as provided in
Section 8 hereof) shall be available for options under the Plan. Such shares may
be  authorized  and  unissued  shares or may be  treasury  shares.  If an option
expires,  terminates or is canceled without being exercised,  new options may be
thereafter  granted  covering such shares.  In order to meet the requirements of
Code Section  162(m),  which  section  limits the  Company's  tax  deduction for
compensation paid to certain officers to $1 million per year, the Plan limits to
100,000 the aggregate number of options that may be awarded to any one employee.
No stock option may be granted more than ten years after the  effective  date of
the Plan.

5.     TERMS AND CONDITIONS OF INCENTIVE STOCK OPTIONS

       Incentive  stock  options may be granted only to employees of the Company
and its  subsidiaries.  Each incentive stock option granted under the Plan to an
employee  shall be  designated  as such and shall be  evidenced  by an incentive
stock option  agreement in such form as the Committee shall approve from time to
time,  which  agreement shall conform with this Plan and which shall contain the
following terms and conditions:

       (a) Number of Shares.  The option  agreement  shall specify the number of
shares to which it pertains.

       (b) Purchase Price.  The purchase price for each option shall be not less
       than the fair  market  value of the  stock  at the time  such  option  is
       granted.  The Committee  shall determine the purchase price. If an option
       is granted to an employee who at the time of grant owns stock  possessing
       more than ten percent of the total  combined  voting power of all classes
       of stock of the Company (a "10-percent Shareholder"),  the purchase price
       shall be at least 110% of the fair market  value of the stock  subject to
       the option.

       (c)  Duration  of  Option.  Each stock  option by its terms  shall not be
       exercisable  after the  expiration of ten years from the date such option
       is  granted.  In the  case of an  incentive  stock  option  granted  to a
       10-percent Shareholder,  the option by its terms shall not be exercisable
       after the expiration of five years from the date such option is granted.

       (d)  Options  Nontransferable.  Each  option  by its  terms  shall not be
       transferable  by the  optionee  otherwise  than by  will  or the  laws of
       descent and distribution,  and shall be exercisable  during his lifetime,
       only by the optionee,  the optionee's  guardian or the  optionee's  legal
       representative.

       (e) Exercise  Period.  Subject to the  restriction  in Section 5(f),  the
       exercise of each  option  shall be subject to such  conditions  as may be
       imposed by the  Committee  and  specified  in the option  agreement.  The
       Committee may, among other things, specify a minimum length of employment
       and may stagger the period of exercise by  providing  that only a certain
       percentage of options may be exercised each year.

       (f) Payment of Option  Price.  An option shall be exercised  upon written
       notice to the Company accompanied by payment in full for the shares being
       acquired.  The payment shall be made in cash, check or wire transfer;  by
       delivery of shares of Common Stock of the Company  registered in the name
       of the  optionee,  endorsed  in blank,  the value of which will be deemed
       equal to the closing market price of such shares on the date of exercise;
       or,  at  the  discretion  of  the  Committee,  by a  so-called  "cashless
       exercise"  transaction  that affords the optionee the opportunity to sell
       immediately some or all of the shares  underlying the exercise portion of
       the  option  in  order  to  generate  sufficient  cash to pay the  option
       exercise price and/or to satisfy  withholding tax obligations  related to
       the option.

       (g) Maximum Value of Shares.  No incentive  option shall be granted to an
       employee under this Plan or any other  incentive stock option plan of the
       Company or its  subsidiaries to purchase shares as to which the aggregate
       fair  market  value  (determined  as of the date of grant) of the  Common
       Stock which first become exercisable by the employee in any calendar year
       exceeds $100,000.

       (h)  Rights as a  Shareholder.  The  optionee  shall  have no rights as a
       shareholder  with respect to any shares for which he is granted an option
       until the date of issuance to him of a stock  certificate for such shares
       and no  adjustment  shall be made for any  dividends  or other rights the
       record  date for which is prior to the date  such  stock  certificate  is
       issued.

       (i) General Restriction.  Each option shall be subject to the requirement
       that,  if at any time the  Board of  Directors  shall  determine,  in its
       discretion, that the listing, registration or qualification of the shares
       subject to such option upon any securities exchange or under any state or
       federal  law, or the consent or approval of any  governmental  regulatory
       body, is necessary or desirable as a condition of, or in connection with,
       the  granting  of such  option  or the  issuance  or  purchase  of shares
       thereunder,  such option may not be  exercised in whole or in part unless
       such listing, registration, qualification, consent or approval shall have
       been effected or obtained free of any  conditions  not  acceptable to the
       Board of Directors.

6.     TERMS AND CONDITIONS OF NONQUALIFIED STOCK OPTIONS

       Options other than incentive stock options may be granted under this Plan
to both eligible  employees and eligible  nonemployees.  Each such  nonqualified
option shall be evidenced by a  nonqualified  stock option  agreement,  shall be
designated as a "nonqualified  stock option," and shall conform to the foregoing
provisions of Section 5 except the purchase price  requirements of Section 5(b),
the  10-percent  Shareholder  restriction  of Section 5(c),  the  prohibition on
transferability of Section 5(d) to the extent provided in the nonqualified stock
option agreement, and the maximum value of grants of Section 5(g). The Committee
may include,  in its  discretion,  any terms or  conditions in addition to those
specified  in Section  5. To the extent an option  exceeds  the  limitations  of
Section  5(g),  it shall be deemed a  nonqualified  option  and shall  otherwise
remain in full force and effect. A nonqualified option may have a duration of 10
years and one day from the date such option is granted.

7.     TERMINATION OF EMPLOYMENT - EFFECT ON OPTIONS

       If the  employment  of an optionee  terminates  for any reason other than
death or disability,  an option may be exercised by him at any time prior to the
earlier of the  expiration  date of the option or the expiration of three months
after the date of  termination,  but only if,  and to the  extent  that,  he was
entitled to exercise the option at the date of such termination. Notwithstanding
the foregoing, an option may not be exercised after termination of employment if
the Committee  determines  that the  termination  of employment of such optionee
resulted from willful acts,  or failure to act, by the optionee  detrimental  to
the Company or any of its subsidiaries. The Committee shall determine whether an
authorized  leave of absence shall  constitute a termination  of employment  for
purposes of this Plan.

       If an optionee's  employment  terminates by reason of disability  (within
the meaning of Section 105 (d)(4) of the Internal  Revenue  Code) or death,  his
option may be  exercised at any time prior to the earlier of the  expiration  of
the  option  or the  expiration  of  one  year  following  the  date  employment
terminated due to disability or death.

       If  employment  of the  optionee  terminates  for any  reason  other than
disability,  retirement or death, any unpaid balance remaining on any promissory
note used in the  purchase of stock shall  become due and payable  upon not less
than three  months'  notice from the  Company,  which notice may be given at any
time after such termination; provided, however, that such unpaid balance on such
promissory  note shall  become due and payable  five years from the date of such
termination, unless the note has an earlier due date. In the case of termination
due to death,  any unpaid  balance  remaining  on such note on the date of death
shall  become due and payable one year from such date.  "Retirement"  shall mean
early or normal  retirement as defined in the Company's  retirement  plan or, in
the event there is no such plan, age 65.

8.     ADJUSTMENT OF SHARES

       In the event of any change in the Common  Stock of the  Company by reason
of any stock dividend, recapitalization,  reorganization, merger, consolidation,
split-up,  combination,  or exchange of shares,  or rights  offering to purchase
Common Stock at a price substantially below fair market value, or of any similar
change  affecting  the  Common  Stock,  the  number  and  kind of  shares  which
thereafter  may be  optioned  and sold under the Plan and the number and kind of
shares subject to option in outstanding option agreements and the purchase price
per share thereof shall be appropriately adjusted consistent with such change in
such manner as the Committee may deem equitable to prevent substantial  dilution
or enlargement of the rights granted to, or available for,  participants  in the
Plan.

9.     NO EMPLOYMENT RIGHTS

       Neither the Plan nor any options  granted  under it shall confer upon any
recipient any right with respect to  continuance of employment by the Company or
any  subsidiary,  nor  shall  they  interfere  in any way with the  right of the
Company or any  subsidiary  by which a recipient  is employed to  terminate  his
employment at any time.

10.    WITHHOLDING TAXES

       Whenever the Company  proposes or is required to issue or transfer shares
of Common  Stock  under the Plan to an employee  pursuant  to the  exercise of a
nonqualified  stock  option,  the  Company  shall have the right to require  the
recipient to remit to the Company an amount  sufficient  to satisfy any federal,
state  or local  withholding  tax  requirements  prior  to the  delivery  of any
certificate  or  certificates  for such  shares.  To the extent  provided in the
nonqualified  stock  option  agreement,  the  amount  of  such  withholding  tax
requirements  may be  satisfied by delivery of shares of the Common Stock of the
Company  registered in the name of the  optionee,  duly assigned to the Company.
Any shares so delivered shall be deemed to have a value equal to the fair market
value of the shares on such date.

11.    CHANGE IN CONTROL

       Upon  acquisition of thirty percent or more of the Company's  outstanding
shares of stock having general voting rights by an unaffiliated  person,  entity
or group, the Committee shall notify, in writing,  each holder of an outstanding
option of such change in control.  Notwithstanding  any other  provision of this
Plan or any option  agreement,  all options  shall become fully  exercisable  on
receipt of such notice.

12.    AMENDMENT AND DISCONTINUANCE

       This Plan may be amended,  modified or terminated by the  shareholders of
the Company or by the Board of Directors, except that the Board may not, without
approval of the  shareholders,  materially  increase  the  benefits  accruing to
participants  under the Plan,  increase the maximum number of shares as to which
options may be granted under the Plan,  change the minimum option price,  change
the class of  eligible  employees,  extend the period for which  options  may be
granted or exercised,  or withdraw the  authority to administer  the Plan from a
Committee  consisting  of directors  not eligible to receive  options  under the
Plan.  Notwithstanding  the  foregoing,  to the  extent  permitted  by law,  the
Committee may amend the Plan without the approval of shareholders, to the extent
it deems  necessary to cause  options  granted  under the Plan to be exempt from
Section  16(b) of the Exchange Act and  deductible  compensation  under  Section
16s(m) of the Code.  Except as required by law, no amendment,  modification,  or
termination  of the Plan may,  without the written  consent of a participant  to
whom any option shall theretofore have been awarded, adversely affect the rights
of such participant under such option.

13.    EFFECTIVE DATE

       The effective date of this amended Plan is August 12, 1999, provided that
the amendment is approved by the  shareholders  of the Company on that date. The
original plan was adopted on August 20, 1997.

14.    GOVERNING LAW

       To the  extent  not  inconsistent  with the  provisions  of the  Internal
Revenue  Code that relate to  incentive  stock  options and  nonqualified  stock
options,  this Plan and any option  agreement  adopted  pursuant  to it shall be
construed under the laws of the State of New York.

                                                                       Exhibit B

                             DETECTION SYSTEMS, INC.
                     NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

                        Adopted by the Board of Directors
                                September 4, 1998


         This is a stock plan  pursuant to which  options to purchase the Common
Stock of Detection  Systems,  Inc., a New York corporation (the  "Corporation"),
may  be  granted  to  non-employee  directors  of  the  Corporation  as  partial
compensation  for their  service as  directors.  This plan shall be known as the
Non-Employee Director Stock Option Plan (the "Plan"). The purpose of the Plan is
to obtain and retain the  services of  qualified  persons who are not  full-time
employees of the Corporation to serve as directors.

         SECTION  1.  Administration.  The  Plan  shall be  administered  by the
Corporation's Board of Directors (the "Board").  The Board shall, subject to the
provisions of the Plan and Section 9 in particular, grant options under the Plan
and shall  have the power to  construe  the Plan,  to  determine  all  questions
thereunder,  and  to  adopt  and  amend  such  rules  and  regulations  for  the
administration of the Plan as it may deem desirable.

         SECTION 2. Shares  Available.  The Board shall reserve for the purposes
of this Plan, out of the  authorized but unissued  shares of Common Stock of the
Corporation,  or out of shares of Common Stock held in its  Treasury,  or partly
out of each, as shall be  determined  by the Board,  a total of 50,000 shares of
the Common Stock (or the number and kind of shares of stock or other  securities
which, in accordance with Section 7 of this Plan, shall be substituted for those
shares or to which those shares shall be adjusted).  In the event that an option
granted  under the Plan to any  non-employee  director  expires or is terminated
unexercised as to any shares covered thereby,  the shares not purchased under it
shall thereafter again be available for the purposes of this Plan.

         SECTION 3. Eligibility.  Each  member  of  the  Corporation's  Board of
Directors  who  is not a full-time  employee of the  Corporation  ("non-employee
director") shall be eligible to receive stock options under this Plan.

         SECTION 4. Grants and Terms of Options; Option Agreements. The Board of
Directors may grant options from time to time under this Plan, provided that any
options  granted  prior  to  ratification  of  this  Plan  by the  Corporation's
shareholders  as provided in Section 8 below shall be subject to receipt of that
ratification.  The number of shares  purchasable under each option and all other
terms  and  conditions  of the  option  shall be as  determined  by the Board of
Directors,  provided  that,  unless this Plan is validly  amended as provided in
Section  9 below,  in the case of any  inconsistency  between  this Plan and the
terms and  conditions of any option,  the provisions of this Plan shall prevail.
As soon as  practicable  after  the  grant of an  option  under  the  Plan,  the
Corporation  and the  non-employee  director  shall  enter  into a Stock  Option
Agreement  evidencing the option so granted and its terms and  conditions.  That
agreement  shall be in such form,  consistent  with the Plan, as the Board shall
deem appropriate.

         SECTION 5.  Exercise and Term of Options.

                  (a) Options  granted  under the Plan shall be  exercisable  as
provided  in the  terms  of the  option  grant  and  the  related  Stock  Option
Agreement.

                  (b) The option  exercise  price of the shares of Common  Stock
subject  to options  shall be 100% of the market  value of the shares on the day
the option is  granted.  The option  price  will be  subject  to  adjustment  in
accordance  with the  provisions of Section 7 of this Plan. For purposes of this
Plan,  the  market  value of a share  of  Common  Stock on any day  shall be the
closing  price  of  such a share  on that  day on the  National  Association  of
Securities Dealers Automated Quotation System ("NASDAQ") or, if there is no such
price on that  day,  the  closing  price of such a share on  NASDAQ  on the last
preceding  day on which  there  was  such a price,  except  that,  if the  Board
determines  that  NASDAQ is not the  principal  trading  market  system  for the
Corporation's  Common Stock, then the market value shall be the reported closing
price of the Common Stock on such other  market  system or exchange as the Board
determines is then the principal  trading market for shares of the Corporation's
Common Stock.

                  (c) Options  granted under the Plan shall have a term of up to
ten years from the date of the granting thereof,  provided,  however,  that each
option shall  automatically  terminate at the close of business on the 210th day
after the day on which the non-employee  director ceases to be a director of the
Corporation and if that day is not a regular  business day at the  Corporation's
principal  office,  then at the  close  of  business  of the next  such  regular
business day.

                  (d) Options  granted under this Plan shall not be transferable
by the  non-employee  director  otherwise  than by  will,  or if he or she  dies
intestate,  by the laws of descent and  distribution of the state of domicile at
the time of death,  and  options  shall be  exercisable  during  the  director's
lifetime only by the director.

         SECTION 6.  Manner of  Exercise of Option.  Options  granted  hereunder
shall be exercised by the director or the director's  executor or  administrator
("optionee")  delivering to the  Corporation,  from time to time within the time
limits specified in Section 5 hereof, a written notice  specifying the number of
shares the optionee then desires to purchase  together  with (i) cash,  check or
wire transfer  payable in United States currency to the order of the Corporation
for an amount equal to the option price for the shares being purchased,  or (ii)
shares of the Corporation's  Common Stock owned by the optionee duly endorsed to
the order of the  Corporation,  the value of which  will be deemed  equal to the
closing  market  price of such  shares  on the date of  exercise,  or (iii)  any
combination of the  foregoing,  and such other  instruments  or agreements  duly
signed by the optionee as in the opinion of counsel for the  Corporation  may be
necessary  or  advisable  in order that the  issuance  of such  number of shares
comply with applicable  rules and regulations  under the Securities Act of 1933,
any  appropriate  state  securities  laws or any  applicable  requirement of any
national  stock  exchange or quotation  or market  system on which the shares of
Common Stock may then be traded.  As soon as practicable after any such exercise
of the option in whole or in part by the optionee,  the Corporation will deliver
to the optionee at the principal  offices of the Corporation,  a certificate for
the  number of  shares  with  respect  to which the  option  shall  have been so
exercised, issued in the optionee's name. The stock certificate shall carry such
appropriate  legend,  and  such  written  instructions  shall  be  given  to the
Corporation's transfer agent, as may be deemed necessary or advisable by counsel
to the  Corporation in order to comply with the  requirements  of the Securities
Act of 1933 or any state securities laws.

         SECTION 7. Adjustment of Number of Shares. If a dividend or stock split
shall  hereinafter be declared upon the Common Stock of the Corporation  payable
in shares  of  Common  Stock of the  Corporation,  then the  number of shares of
Common Stock then subject to any  outstanding  option under the Plan, the number
of shares reserved for issuance under those outstanding  options, and the number
of shares  reserved for issuance  pursuant to the Plan but not yet covered by an
option shall be adjusted by adding to each such share the number of shares which
would be  distributable  thereon if the share had been  outstanding  on the date
fixed for determining the Shareholders entitled to receive the stock dividend or
stock split.  If the  outstanding  shares of the Common Stock of the Corporation
shall be changed into or exchanged  for a different  number or kind of shares of
stock or other  securities of the Corporation  whether  through  reorganization,
recapitalization or  reclassification,  then there shall be substituted for each
share of Common Stock subject to any  outstanding  option under the Plan and for
each share of Common Stock  reserved  for issuance  pursuant to the Plan but not
yet  covered  by an  option,  the  number  and kind of  shares of stock or other
securities into which each outstanding share of Common Stock shall be so changed
or for which each such share shall be exchanged.

         If,  prior to the  delivery  by the  Corporation  of all the  shares in
respect of which an option has been granted hereunder, a merger,  consolidation,
or dissolution in which the Corporation is not the surviving  corporation  shall
occur or a transfer of  substantially  all the assets of the  Corporation  shall
occur:

                  (a) If provision has been made in writing in  connection  with
the  transaction  for the assumption and continuance of any such option granted,
or the  substitution  for such option of a new option covering the shares of the
successor  corporation,  with  appropriate  adjustment  as to number and kind of
shares and prices, the option granted,  or the new option substituted  therefor,
as the case may be, shall continue in the manner and under the terms provided.

                  (b) If provision has not been made in the  transaction for the
continuance   and  assumption  of  an  option  granted   hereunder  or  for  the
substitution of an option covering the shares of the successor corporation, then
the  holder of an  option  granted  hereunder  shall be  entitled,  prior to the
effective  date of any the  transaction,  to purchase  the full number of shares
under the option,  failing  which  purchase,  any  unexercised  portion shall be
deemed canceled as of the effective transaction date.

                  If there is any change,  other than as specified above in this
Section 7, in the number or kind of  outstanding  shares of Common  Stock of the
Corporation or of any stock or other  securities into which the Common Stock has
been changed or for which it has been  exchanged,  then  appropriate  adjustment
shall be made in the  number  and kind of shares  subject  to and  reserved  for
issuance pursuant to this Plan and as to which  outstanding  options or portions
then  unexercised  shall  be  exercisable,  to the end  that  the  proportionate
interest of the holder of an option and a  prospective  holder,  with respect to
options theretofore granted and to be granted, shall be maintained as before the
occurrence of the change or exchange.  In the case of any such  substitution  or
adjustment  as provided  for in this  Section,  the option  price for each share
covered  thereby prior to such  substitution  or  adjustment  will be the option
price  for all  shares  of stock or  other  securities  which  shall  have  been
substituted  for the share or to which the share has been  adjusted  pursuant to
this Section. No adjustment or substitution provided for in this Section 7 shall
require the Corporation to sell a fractional  share, and the total  substitution
or adjustment with respect to each option shall be limited accordingly.

         SECTION 8.  Effective  Date and Duration of Stock Plan.  The  effective
date of the Plan shall be  September  4, 1998,  the date of its  adoption by the
Board.  The duration of the Plan shall be ten years from the effective date. The
Plan and all options granted  hereunder prior to the  Corporation's  1999 annual
meeting of shareholders shall be subject to ratification by shareholders at that
or any prior meeting.

         SECTION 9.  Amendment  of the Plan.  The Board  shall have the right to
amend,  suspend,  or terminate  this Plan at any time,  except that  shareholder
approval shall be required for any amendment which:

                  (a) increases the maximum number of shares subject to the Plan
(subject to Section 7 above);

                  (b) changes the  provisions of the Plan  regarding the
determination  of the option  exercise price (subject to Section 7 above);

                  (c) changes the maximum period during which any options may be
granted or remain outstanding; or

                  (d)  changes  the  requirements  as to the  class  of  persons
eligible to receive options.

Termination or suspension of the Plan or any amendment of it shall not,  without
the consent of a holder of an outstanding  option issued under the Plan,  affect
the holder's rights under that option.

                             DETECTION SYSTEMS, INC.
