   NASDAQ Sends NAPCO Staff Determination Letter Related to Delayed Form 10-K
                                     Filing

AMITYVILLE, NEW YORK - OCTOBER 16, 2003 -- NAPCO Security Systems, Inc.,
(Nasdaq: NSSC), announced today that due to its previously announced delay in
filing its Form 10-K for the fiscal year ended June 30, 2003, it received a
NASDAQ Staff Determination letter on October 15, 2003. This letter reflects
standard NASDAQ procedure for companies making delayed public filings.

The letter indicated that, due to the delayed Form 10-K filing, NAPCO is not
currently in compliance with the filing requirements for continued listing set
forth in NASDAQ Marketplace Rule 4310(c)(14) and that its Common Stock is
subject to possible delisting from the NASDAQ National Market. As the next step
in this process, NAPCO will request a NASDAQ Listing Qualifications Panel
hearing to review the Staff Determination. The hearing request will stay the
delisting of the Company's securities pending the Panel's decision. Delisting
can be prevented by the Panel, but there can be no assurance that the Panel
will grant NAPCO's request for continued listing. However, the Company
understands that if it files its 2003 Form 10-K prior to the hearing evidencing
compliance with all continued listing requirements, the Company's normal
listing may be reinstated. The letter also indicated that the Company's stock
ticker symbol will become (NSSCE) beginning on Friday, October 17, 2003 and
will continue throughout the filing delinquency.

As previously reported in the press release of October 14, 2003, the delay in
filing the Company's Form 10-K relates to the resolution of an international tax
matter concerning the Company's Dominican Republic subsidiary, and although
there can be no assurance of the outcome, management believes that the issue
will be resolved satisfactorily within approximately six weeks and then promptly
file its Form 10-K.
