    NAPCO Security Systems, Inc. Announces Second Quarter Financial Results

                 -Second Quarter EPS $0.06 vs. $0.07 Last Year-

     AMITYVILLE, N.Y.--(BUSINESS WIRE)--Feb. 6, 2007--NAPCO Security Systems,
Inc., (Nasdaq: NSSC), one of the world's leading suppliers of high performance
electronic security equipment for over 30 years, today announced financial
results for its second quarter ended December 31, 2006.

     Net sales for the three months ended December 31, 2006 was $16.1 million as
compared to $17.2 million for the same quarter a year earlier, a decrease of 6%.
Net income for the quarter was $1.1 million, or $0.06 per diluted share,
compared to net income of $1.5 million, or $0.07 per diluted share, for the same
year ago period, a decrease of $400,000.

     Net sales for the six months ended December 31, 2006 was $30.1 million as
compared to $31.4 million for the prior year period, a decrease of 4%. Net
income for the six months ended December 31, 2006 was $2.1 million or $0.10 per
diluted share, as compared to $2.3 million or $0.11 per diluted share in the
prior year period, a decrease of $200,000. Net sales and net income for the
three and six months declined due to lower sales in the Company's European
markets.

     Richard Soloway, Chairman and President, noted, "We have taken several
steps that we believe will lead to improved European sales in the near term,
including the realignment of the European sales force in order to get better
penetration and increased presence in these markets.

     "While Gross Profit was lower as a result of lower sales, the Company's
Gross Margin percentage increased during this past quarter to 36.2% from 35.1% a
year ago. The increase in Gross Margin percentage occurred primarily as a result
of increased overhead absorption resulting from increased production, a more
favorable product mix resulting from the increased sales of the Company's door
locking and access control products as well as the positive effect of the
Company's raw materials cost reduction program.

     "The Company's inventory levels increased significantly during the first
two quarters of fiscal 2007. The Company's policy is to level-load its
production schedule during the year, even though its historical sales cycle is
with a larger portion of sales occurring in the latter fiscal quarters. This
stabilizes the Company's work force and increases manufacturing efficiencies.
This type of production planning also typically leads to significant increases
in inventory during the earlier quarters. In addition, the Company produced
additional inventory to support the introduction of the Company's new Freedom 64
code-less intrusion alarm system and several other key new products as well as
to support a projection of higher sales in the first two quarters of fiscal
2007. The inventory increase has centered on core components and new products.
The Company has recently taken several steps in order to reduce inventory
levels."

     Mr. Soloway concluded, "Our fundamental strengths include the broadest line
of high quality, innovative products in the industry designed to serve the needs
of the residential, business, military and government markets and encompassing
products for access control, intrusion and fire alarm systems, and electronic
locking devices. We are one of the few independent but meaningful security
product and systems providers. This array of products and markets is supported
by a large R&D effort with the mandate of using the latest technologies to
develop new products and systems for the sole purpose of bringing greater
security into our customers' lives. I am looking forward to the benefits from
our many new product introductions, our new European sales structure as well as
our continuing search for accretive acquisitions."
