     NAPCO DISCLAIMS STATEMENT IN BUSINESS WEEK'S INSIDE WALL STREET COLUMN

MAY 28, 2004 AMITYVILLE, NY, NAPCO SECURITY SYSTEMS, INC. (NASDAQ:NSSC) noted
that the current June 7, 2004 Business Week Inside Wall Street column discussing
NAPCO Security Systems, Inc. has erroneously ascribed the following statement
about ADT's SafeWatch EZ(TM) to Mr. Richard Soloway, CEO of NAPCO stating, "in
two years, EZ will be installed in 50% of that volume." That statement was
supposedly made in response to the statement that ADT installs 600,000 security
systems a year.

While Mr. Soloway believes that SafeWatch EZ(TM) will be a promising product for
ADT and NAPCO, he made no such statement and at this time cannot make any
estimate of the number of units that will be sold.
