Irving, Texas – September 12, 2002 – Integrated Security Systems, Inc. (OTCBB Symbol: IZZI) today announced today that orders received by its wholly owned subsidiary, B&B Electromatic, Inc., for its CR 25 anti-terrorist crash barrier during the first quarter of the fiscal year beginning July 1, 2002, have exceeded expectations. During the quarter B&B has received follow-on orders from existing oil refinery customers, new orders from two different oil refinery companies, and orders for other perimeter security applications. The combined total number of units ordered this quarter exceeds the total number of units shipped for the entire prior fiscal year. During the month of September alone, ten (10) crash barriers will be shipped to three companies.

“After the events of September 11, 2001, there was a rush to protect the most vulnerable perimeter areas at critical facilities, particularly at the entrances”, said Jack Caldwell, President of B&B. “The orders we are seeing now are the results of well planned and budgeted capital projects to better secure the perimeters of such facilities as oil refineries, chemical plants, power plants, and state and federal facilities. This is especially evident in the follow-on orders received from the same facilities which placed orders early on after September 11”. Mr. Caldwell concluded, “We expect this trend to continue for the foreseeable future.”

B&B’s CR 25 anti-terrorist crash barrier comes in both a manual and electrical version. Each version has a vertical to horizontal arm, is equipped with an energy absorption cable assembly and weatherproof housing. The manual version has been successfully crash tested to U.S. Navy specifications OR-98-09-88 and M-56-86-05 with a level 1/L2 rating and Department of the Army rating level of KN1-LN2. It is listed by the US Army Corps of Engineers in their document Protection Against Malevolent Use of Vehicles at Nuclear Power Plants (NUREG/CR-6190 Vol. 2, Rev. 1). The electrical version has the same physical characteristics as the manual version.
