              NAPCO SECURITY SYSTEMS, INC. REPORTS RECORD BREAKING
                   2ND FISCAL QUARTER SALES AND STRONG PROFITS

             - Sales up 10% for Second Quarter, 20% for Six Months-

          - Net Income Up 20% for Second Quarter, 211% for Six Months--

          -Strong Distributor Acceptance of Reallocation Strategy and
              Broad Product Portfolio Leads to Optimistic Outlook-

AMITYVILLE, NEW YORK - FEBRUARY 8, 2005 - 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 financial results for its
second quarter and six months ended December 31, 2004.

Net sales for the second quarter ended December 31, 2004 increased 10% to
$16,019,000 from $14,629,000 reported for the same quarter a year earlier. Net
income for the quarter increased 20% to $872,000 or $0.10 per diluted share
compared to net income of $728,000, or $0.08 per diluted share, reported for the
same year ago period. The increase in sales for the second quarter was due
primarily to increased sales of the Company's Alarm Lock door locking and NAPCO
burglar and fire alarm products.

Net sales for the six months ended December 31, 2004 increased 20% to
$29,459,000 from $24,464,000 reported for the six months ended December 31,
2003. Net income for the first half of fiscal 2004 increased 211% to $1,385,000,
or $0.15 per diluted share, compared to net income of $446,000, or $0.05 per
diluted share, for the same period a year earlier.

Richard Soloway, Chairman and President, stated, "As evidenced by our strong
sales in the first quarter of fiscal 2005, and subsequently extended through the
second fiscal quarter, our business strategy of reallocating our burglar and
fire alarm sales across our extensive national network of independent
distributors has been well received and the revitalization of that segment of
our business has taken hold."

"Our independent distributor network has done an outstanding job of reaching out
to an expanding list of security dealers who focus on residential, commercial,
industrial and governmental security installations, resulting in increased
acceptance and sales of NAPCO alarm products," noted Mr. Soloway.

                                                                       - More -





"In addition," Mr. Soloway added, "NAPCO has shown major improvements in our
financial metrics. In the past six months we have reduced our outstanding bank
debt by approximately $4 million to $4.4 million and since December 31, 2003 by
$9.2 million. Net cash provided by operating activities during this period was
$5.1 million compared to $2.6 million a year ago."

NAPCO has recently introduced its newest, expanded catalog (available on
request) demonstrating once again NAPCO's commitment to its customer's need for
state-of-the-art breakthrough security products and systems; a commitment that
is met by devoting over $4 million annually to R&D.

"As the second half of our fiscal year is historically our strongest, we can
look forward with a great degree of confidence to reporting significant sales
gains over the remainder of the fiscal year, and, since our bottom line is
sensitive to volume, we can also expect a positive impact on net income and per
share results. We look forward to reporting another very successful year," Mr.
Soloway concluded.

As of December 31, 2004, NAPCO's current ratio was 4.9-to-1, working capital
stood at $28.7 million and long-term debt was $4.4 million with a long-term
debt-to-equity ratio of 0.11-to-1. Inventory, which normally builds as NAPCO
enters its strongest revenue quarters, has been carefully controlled and at
calendar year end 2004 was $15.0 million compared to $17.5 million at December
31, 2003. Inventories normally increase after the first half in recognition of
the anticipated cyclical increase in sales in the third and fourth fiscal
quarters. EBITDA* (Earnings before interest, taxes, depreciation and
amortization) has similarly improved during the six months ending December 31,
2004, almost doubling from last year to $2.8 million, compared to $1.5 million."
