                          DETECTION SYSTEMS, INC.
                         DEFERRED COMPENSATION PLAN
                           [8/20/97 Restatement]

1.    Purpose

      Detection Systems, Inc. (the "Company") has adopted this Deferred
Compensation Plan (the "Plan") to assist its officers with their
individual tax and retirement income planning and to permit the Company to
remain competitive in attracting, retaining, motivating and rewarding key
executives who can directly influence the Company's operating results.
The Plan permits officers to defer the receipt of salary or bonuses which
they may be entitled to receive from the Company and the Company to make
Company contributions for the benefit of its officers.  The Plan was
originally adopted as of August 1, 1986.  This restatement is effective as
of August 20, 1997.

2.    Eligibility

      Any officer of the Company is eligible to participate in this Plan.

3.    Contributions

      a.    Company Contributions

            The Company may contribute to an officer's Participant Account
any amount, at any time and for any reason as the Company in its sole
discretion may determine. The Company has no obligation to make such
contributions to any officer's account and contributions need not be the
same for all officers.
 
      b.    Officer Deferrals

            (1)  Amount of Deferral.  In addition to Company
contributions, a participant may elect to defer receipt of up to 10
percent of his or her base salary and up to 100 percent of any bonus
otherwise payable to the participant by the Company during a calendar year.

            (2)  Time for Electing Deferral.  An election to commence a
deferral may be made at any time in accordance with the procedures set
forth in subsection (3) below, provided that any election to defer
compensation must be made prior to the time that such compensation is to
be earned by the participant. Any election so made shall remain in effect
until the participant elects in writing to change his or her election.

            (3)  Manner of Electing Deferral.  A participant shall elect a
deferral by giving written notice to the Committee in a form prescribed by
the Committee.  The notice shall include (1) the amount to be deferred;
(2) the period with respect to which the deferral relates; (3) an election
of a lump sum payment or the number of monthly installments (not to exceed
120) for the payment of the deferred amounts; and (4) the date benefit
payments are to be made or to commence.  A participant may designate any
date for the commencement of benefit payments but in the event the
participant retires or otherwise terminates employment, benefit payments
shall commence within 60 days of retirement or termination notwithstanding
any later date specified in the participant's election form.  In addition,
if any scheduled payment from this Plan during a taxable year of the
Company would, in combination with other compensatory payments to the
participant during such year, result in the participant's compensation
exceeding the $1 million cap under Code Section 162(m), the Company in its
sole discretion may defer benefit payments to the first subsequent year
when the participant's compensation will not exceed the $1 million cap.

4.    Participant Accounts

      For each participant there shall be established both a Participant
Interest Account and a Participant Stock Account (collectively referred to
as the Participant Account).  Each Participant Interest Account shall be
credited with the amounts deferred by, or contributed by the Company on
behalf of, a participant plus an assumed annual interest on such amounts
at a rate designated by the Committee from time to time as the benchmark
assumed interest rate.  This assumed interest shall be compounded annually
and treated as earned from the date of crediting to the date of
withdrawal.  The Participant Stock Account shall be credited at the end of
each month with the number of shares of Company Common Stock that could be
purchased at the Common Stock's then fair market value with the amounts
deferred by, or contributed by the Company on behalf of, a participant
each month plus any hypothetical dividends payable during such month on
the Company Common Stock previously credited to the Participant Stock
Account.  The value of each Participant Interest and Stock Account shall
be adjusted no less frequently than monthly to reflect contributions to
the Account, payments from the Account as hereinafter provided, and
assumed interest on the Interest Account or additional stock purchases
from hypothetical dividends on the Stock Account.  The Stock Account shall
also be adjusted no less frequently than monthly to reflect any gains (or
losses) in the fair market value of Company Common Stock.

      All amounts credited to Participant Accounts shall be fully vested
at all times.  Except for the possible claims of the Company's general
creditors, they shall not be subject to forfeiture on account of any
action by a participant or by the Company, including termination of
employment.

      The maintenance of individual Participant Accounts is for
bookkeeping purposes only.  The Company is not obligated to make actual
contributions to fund this plan or to acquire or set aside any particular
assets for the discharge of its obligations, nor is any participant to
have any property rights in any particular assets held by the Company,
whether or not held for the purpose of funding the Company's obligations
hereunder.

5.    Payment of Deferred Amounts

No withdrawal may be made from a Participant Account except as provided in
this section 5.  Payments from an Account shall normally commence within
60 days following a participant's retirement or other termination of
employment provided that a participant may elect an earlier date for
payment of his own deferrals in the election form to which his deferred
amounts relate.  In the case of financial hardship, the Committee, in its
sole discretion, may distribute all or a portion of an Account before
termination of employment but the amount of the distribution shall not
exceed the amount needed to relieve the financial hardship.  In the case
of a potential violation of the $1 million cap on compensation under Code
Section 162(m), the Company may defer payments to a later year as
authorized in section 3.  Any payments deferred for Section 162(m)
purposes shall be paid as soon as payment would no longer constitute a
violation of the Code Section 162(m) compensation cap.  Such payments
shall be made in a manner as consistent as possible with the participant's
original deferral election.  For example, if installment payments were
elected, the originally scheduled installment payments shall be made on
schedule for a year even if the participant is paid a lump sum in that
same year for the deferred payments.

      At any time prior to his becoming eligible to commence receiving
benefits, the participant shall make a single, irrevocable election with
the Committee to receive his benefits from either his Participant Interest
Account or his Participant Stock Account.  If no such election is made, or
in the event of the participant's death, payment shall be made from
whichever account has the higher value, measured at the time of the
benefit commencement date.  Payments from an Interest Account shall be
made only in cash and payments from a Stock Account shall be made only in
stock, provided that any fractional shares from a Stock Account shall be
paid in cash.

      An aggregate of 182,250 shares of Company Common Stock (subject to
substitution or adjustment as provided below) shall be available for stock
payments under this Plan.  Such shares may be authorized and unissued
shares or may be treasury 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 are available for stock payments under the Plan 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.

      All payments from a Participant Account shall be made in the form of
either a lump sum payment or monthly installments over a period of years
not to exceed ten as elected by the participant.  This election shall be
made on the participant's deferral notice, provided that the participant
may change this election, by written notice to the Committee at any time
up to 36 months prior to the actual benefit commencement date.  Any
requested change of an earlier election that is made within the 36 month
period preceding the actual benefit commencement date shall not be
effective and shall be disregarded by the Committee.  Where payments are
made in monthly installments, the balance credited to a Participant
Account shall be adjusted periodically for assumed interest or stock
purchases as provided in section 4.

      If installment payments are elected, the first installment shall
equal the value of the Participant Account at such time multiplied by a
fraction, the numerator of which is one and the denominator of which is
the total number of monthly installments to be made.  All subsequent
installments shall equal the value of the Participant Account as of the
last valuation date preceding the installment which is to be paid
multiplied by a fraction, the numerator of which is one and the
denominator of which is the total number of installments elected minus the
number of installments already paid.

      In the event of a participant's death before the participant has
received all of the deferred payments to which the participant is entitled
hereunder, the remaining number of installments which would have been paid
to the participant shall be paid to the participant's estate in the same
manner that the participant would have received them.

      Notwithstanding a participant's election of installment payments,
the Committee, in its sole discretion, shall have a right to accelerate
any such payments or to make payment of the balance in a Participant
Account in a lump sum.

6.    Participant's Rights Unsecured

      The right of any participant or, if applicable, the participant's
estate, to receive benefits under the provisions of this Plan shall be an
unsecured claim against the general assets of the Company.  Any amounts
held in a Participant Account are a part of the Company's general assets
and shall be reachable by the general creditors of the Company.

7.    Statement of Account

      Statements will be sent to participants no less frequently than
annually setting forth the value of their Participant Accounts.

8.    Transferability
      The rights of a participant under this Plan shall not be
transferable other than by will or the laws of descent and distribution
and are exercisable during the participant's lifetime only by him or by
his guardian or legal representative.

9.    Plan Administrator

      The administrator of this Plan shall be a committee of the Board of
Directors of the Company as from time to time designated by the Board.
The Committee's members shall be non-employees of the Company. The
Committee shall have the authority to adopt rules and regulations for
carrying out the Plan and to interpret, construe and implement the
provisions of the Plan.

10.  Amendment

      This Plan may at any time or from time to time be amended, modified
or terminated by the Company's Board of Directors.  No amendment,
modification or termination shall, without the consent of a participant,
adversely affect such participant's accruals in his or her Participant
Account.

11.  Governing Law

      This Plan and any participant elections hereunder shall be
interpreted and enforced in accordance with the laws of the State of New
York.

12.  Effective Date

      The effective date of this restated Plan is August 20, 1997.

      IN WITNESS WHEREOF, the Company has caused its duly authorized
officer to execute this Plan document on its behalf this 20th day of
August 1997.

                        DETECTION SYSTEMS, INC.

                        By /s/ Frank J. Ryan
                        Frank J. Ryan, Vice President



                            Federal Tax Aspects

      The Plan is a non-qualified deferred compensation plan under the
provisions of the Internal Revenue Code.  At the time a Company
contribution or a participant's deferral of compensation is made, it is
intended that the participants will not recognize income, for Federal
income tax purposes.  In addition, assumed interest and hypothetical
dividends will not be treated as income at the time they are credited to
the participant accounts.

      Participants will recognize ordinary income at the time the Company
contributions and participant deferrals, together with the earnings
credited to these amounts, are actually paid out or made available to the
participants.  The amount of such ordinary income will equal the amount of
cash received plus the fair market value, on the date of payment, of any
shares paid or made available.

      The ultimate sale or exchange of any shares of common stock received
under the Plan will result in either long-term or short term capital gain,
or loss depending on the holding period.  Under current law, long term
capital gains or losses will result upon the disposition of shares that
are held for more than six months.  A participant's basis in the shares
will be the amount of income he recognizes at the time the shares were
actually paid or made available to the participant.

      The Company is not entitled to deduct the amount of contributions or
deferrals into the Plan or the assumed interest or hypothetical dividends
credited to an account.  Instead, the Company is entitled to take a
deduction at the time a participant recognizes income.  The amount of the
deduction is the amount of income that a participant must recognize.

      For Social Security tax (F.I.C.A.) purposes the Company
contributions and participant deferrals under the Plan are taxable as
"wages" at the time the services are performed.  This will result in
Social Security taxes to a participant and to the Company only where a
participant is otherwise below the Social Security Wage Base at the time
the contributions or deferrals are made.

      The Plan is not a tax-qualified plan under Section 401(a) of the
Internal Revenue Code and is not subject to ERISA.  The Company has not
received any ruling from the Internal Revenue Service concerning the tax
consequences of the Plan.

                         DEFERRED STOCK BONUS PLAN
                           [8/20/97 Restatement]

1.    Purpose

      Detection Systems, Inc. (the "Company") has adopted this Deferred
Stock Bonus Plan (the "Plan") for the benefit of its key personnel who
wish to defer the receipt of stock bonuses which they may be entitled to
receive from the Company.  The purposes of the Plan are to assist key
personnel with their individual tax and retirement income planning and to
permit the Company to remain competitive in attracting, retaining,
motivating and rewarding personnel who can directly influence the
Company's operating results.  The Plan was originally adopted as of
January 1, 1989.  This restatement is effective as of August 20, 1997.

2.    Eligibility

      All key personnel selected by the Committee established under
Section 9 shall be eligible to participate in this Plan.

3.    Contributions

      a.    Company Contributions

            The Company may contribute to a participant's account any
amount of Company Stock, at any time and for any reason as the Company in
its sole discretion may determine.  The Company has no obligation to make
such contributions to any participant's account and contributions need not
be the same for all participants.

      b.    Participant Deferrals

            (1)  Amount of Deferral.  In addition to Company
contributions, a participant may elect to defer receipt of up to 100
percent of any stock bonus otherwise payable to the participant by the
Company during a calendar year.

            (2)  Time for Electing Deferral.  An election to commence a
deferral may be made at any time in accordance with the procedures set
forth in subsection (3) below, provided that any election to defer a stock
bonus must be made prior to the time that such stock bonus will be earned
by the participant. Any election so made shall remain in effect until the
participant elects in writing to change his or her election.

            (3)  Manner of Electing Deferral.  A participant shall elect a
deferral by giving written notice to the Committee in a form prescribed by
the Committee.  The notice shall include (1) the amount to be deferred;
(2) the period with respect to which the deferral relates; (3) an election
of a lump sum payment or the number of monthly installments (not to exceed
120) for the payment of the deferred amounts; and (4) the date benefit
payments are to be made or to commence.  A participant may designate any
date for the commencement of benefit payments but in the event the
participant retires or otherwise terminates employment, benefit payments
shall commence within 60 days of retirement or termination notwithstanding
any later date specified in the participant's election form.  In addition,
if any scheduled payment from this Plan during a taxable year of the
Company would, in combination with other compensatory payments to the
participant during such year, result in the participant's compensation
exceeding the $1 million cap under Code Section 162(m), the Company in its
sole discretion may defer benefit payments to the first subsequent year
when the participant's compensation will not exceed the $1 million cap.

4.    Participant Accounts

      For each participant there shall be established both a Participant
Interest Account and a Participant Stock Account (collectively referred to
as the Participant Account).  Each Participant Interest Account shall be
credited with the fair market value, determined as of the date of the
deferral, of the stock bonus deferred on behalf of a participant plus an
assumed annual interest on such amounts at a rate designated by the
Committee from time to time as the benchmark assumed interest rate.  This
assumed interest shall be compounded annually and treated as earned from
the date of crediting to the date of withdrawal. The Participant Stock
Account shall be credited at the end of each month with the number of
shares of Company Common Stock whose payment is deferred plus any
hypothetical dividends payable on the Company Common Stock previously
credited to the Participant Stock Account.  The value of each Participant
Interest and Participant Stock Account shall be adjusted no less
frequently than monthly to reflect contributions to the Account, payments
from the Account as hereinafter provided, and assumed interest on the
Interest Account or additional stock purchases from hypothetical dividends
on the Stock Account.  The Stock Account shall also be adjusted as of the
end of the Company's fiscal year to reflect gains (or losses) in the fair
market value of Company Common Stock.  For purposes of this Plan, the fair
market value of the Company's Common Stock shall equal the Stock's average
share value during the fiscal year preceding the date on which the
valuation is performed.  The Committee has the discretion to determine the
precise method for calculating the average share value.

      All amounts credited to Participant Accounts shall be fully vested
at all times.  Except for the possible claims of the Company's general
creditors, they shall not be subject to forfeiture on account of any
action by a participant or by the Company, including termination of
employment.

      The maintenance of individual Participant Accounts is for
bookkeeping purposes only.  The Company is not obligated to acquire or set
aside any particular assets for the discharge of its obligations, nor is
any participant to have any property rights in any particular assets held
by the Company, whether or not held for the purpose of funding the
Company's obligations hereunder.

5.    Payment of Deferred Amounts

      No withdrawal may be made from a Participant Account except as
provided in this section 5.  Payments from an Account shall normally
commence within 60 days following the earlier of (1) the benefit
commencement date contained in the participant's initial deferral notice
or (2) the participant's retirement or other termination of employment.
At the election of a participant who could be subject to suit under
section 16(b) of the Securities Exchange Act of 1934, payment can be
delayed for up to six months and a day following termination of
employment.  In the case of financial hardship, the Committee, in its sole
discretion, may distribute all or a portion of an Account before the
normal benefit commencement date determined above but the amount of the
distribution shall not exceed the amount needed to relieve the financial
hardship.  In the case of a potential violation of the $1 million cap on
compensation under Code Section 162(m), the Company may defer payments to
a later year as authorized in section 3.  Any payments deferred for
Section 162(m) purposes shall be paid as soon as payment would no longer
constitute a violation of the Code Section 162(m) compensation cap.  Such
payments shall be made in a manner as consistent as possible with the
participant's original deferral election.  For example, if installment
payments were elected, the originally scheduled installment payments shall
be made on schedule for a year even if the participant is paid a lump sum
in that same year for the deferred payments.

      At any time prior to his benefit commencement date, the participant
shall make a single, irrevocable election with the Committee to receive
his benefits from either his Participant Interest Account or his
Participant Stock Account.  If no such election is made or in the event of
the participant's death, payment shall be made from whichever account has
the higher value, measured at the time of the benefit commencement date.
Payments from an Interest Account shall be made only in cash and payments
from a Stock Account shall be made only in stock, provided that any
fractional shares from a Stock Account shall be paid in cash.

      The number of shares of Company Common Stock that shall be available
for stock payments under this Plan shall be limited to a maximum of 10% of
the total shares outstanding.  Such shares may be authorized and unissued
shares or may be treasury 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 are available for stock payments under the Plan 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.

      All payments from a Participant Account shall be made in the form of
either a lump sum payment or monthly installments over a period of years
not to exceed ten as elected by the participant.  This election shall be
made on the participant's deferral notice, provided that the participant
may change this election, by written notice to the Committee at any time
up to 36 months prior to the actual benefit commencement date.  Any
purported change of an earlier election that is made within the 36 month
period preceding the actual benefit commencement date shall not be
effective and shall be disregarded by the Committee.  Where payments are
made in monthly installments, the balance credited to a Participant
Account shall be adjusted periodically for assumed interest or stock
purchases as provided in section 4.

      In the event of a participant's death before the participant has
received all of the deferred payments to which the participant is entitled
hereunder, the remaining number of installments which would have been paid
to the participant shall be paid to the participant's estate in the same
manner that the participant would have received them.

      Notwithstanding a participant's election of installment payments,
the Committee, in its sole discretion, shall have a right to accelerate
any such payments or to make payment of the balance in a Participant
Account in a lump sum.

6.    Participant's Rights Unsecured

      The right of any participant or, if applicable, the participant's
estate, to receive benefits under the provisions of this Plan shall be an
unsecured claim against the general assets of the Company.  Any amounts
held in a Participant Account are a part of the Company's general assets
and shall be reachable by the general creditors of the Company.

7.    Statement of Account

      Statements will be sent to participants no less frequently than
annually setting forth the value of their Participant Accounts.

8.    Transferability

      The rights of a participant under this Plan shall not be
transferable other than by will or the laws of descent and distribution
and are excercisable during the participant's lifetime only by him or by
his guardian or legal representative.

9.    Plan Administrator

      The administrator of this Plan shall be a committee of the Board of
Directors of the Company as from time to time designated by the Board.
The Committee's members shall be non-employees of the Company. The
Committee shall have the authority to adopt rules and regulations for
carrying out the Plan and to interpret, construe and implement the
provisions of the Plan.

10.  Amendment

      This Plan may at any time or from time to time be amended, modified
or terminated by the Company's Board of Directors.  No amendment,
modification or termination shall, without the consent of a participant,
adversely affect such participant's accruals in his or her Participant
Account.

11.  Governing Law

      This Plan and any participant elections hereunder shall be
interpreted and enforced in accordance with the laws of the State of New
York.

12.  Effective Date

      The effective date of this restated Plan is August 20, 1997.

      IN WITNESS WHEREOF, the Company has caused its duly authorized
officer to execute this Plan document on its behalf this 20th day of
August 1997.
