B&B ARMR CORPORATION DELIVERY

TO PETRO-CHEMICAL MANUFACTURER

 Carrollton, Texas – March 9, 2007 – Integrated Security Systems, Inc. (OTCBB Symbol: IZZI) today announced that its wholly owned subsidiary, B&B ARMR Corporation, has delivered the first in a series of high security anti-terrorist barrier systems to one of the largest U.S.-based petro-chemical manufacturers with facilities throughout the world. The barriers will form an integral part of the perimeter defense systems around key chemical sites and represents one example of a private sector response to recently promulgated Homeland Security directives for infrastructure protection.

As part of the Homeland Security initiatives stemming from the terrorists attacks of September 11, 2001, the United States government has been identifying specific private sector companies and industries that pose strategic vulnerabilities in the Nation’s infrastructure. Beginning in late 2006, the Department of Homeland Security (DHS) specified defensive security measures for the chemical manufacturing industry. B&B ARMR has partnered with a number of these companies over many years to provide hard perimeter security systems to minimize the impact of personnel and vehicle-borne threats to facilities. B&B ARMR products meet or exceed all of the specifications required by DHS for the protection of these key facilities as well as the protection of the population residing around the plants.
