ANNOUNCES

B&B ROADWAY ORDER FROM

ILLINOIS DEPARTMENT OF TRANSPORTATION

 Irving, Texas – August 23, 2006 – Integrated Security Systems, Inc. (OTCBB Symbol: IZZI) today announced that B&B Roadway, a majority-owned joint venture partner of its wholly owned subsidiary B&B ARMR, has received a major order from the Illinois Department of Transportation. The order, which exceeds $750,000, is for 80 highway access gates and related equipment. The project is part of an overall city evacuation and traffic management strategy for highway routes leading into and out of the City of Chicago. The total system is designed to restrict access to certain expressway routes in the event of an emergency. This will enable changes in traffic flow so that all lanes can be changed to a single direction of flow, easing movement. Similar systems from B&B Roadway have been developed or are being considered by a number of states and metropolitan areas, particularly for use as hurricane evacuation routes.
