         NAPCO SECURITY SYSTEMS, INC. ANNOUNCES DELAY IN FILING FORM 10K

AMITYVILLE, NEW YORK - OCTOBER 14, 2003 -- NAPCO SECURITY SYSTEMS, INC.,
(NASDAQ: NSSC), one of the world's leading suppliers of high performance
electronic security equipment for over 30 years, announced today that the filing
of the Form 10K for the year ending June 30, 2003 will be delayed beyond the
October 14, 2003 extension date as set by the Securities and Exchange Commission
("SEC"). The delay in filing relates to the resolution of an international tax
matter concerning the Company's Dominican Republic subsidiary.

If the tax matter is not favorably resolved, it may have a material adverse
effect on the Company's fiscal 2003 financial statements. Although there can be
no assurance of the outcome, management believes that the issue will be resolved
satisfactorily. The Company expects to resolve this matter within approximately
six weeks and then promptly file its Form 10K. As a result of the delay, the
Company's annual report to shareholders, proxy statement and annual meeting will
be temporarily delayed as well.

For the fiscal year ended June 30, 2003, the Company expects to report net sales
of $57,376,000 compared to $55,836,000 for the prior fiscal year.
