Business Editors/High-Tech Writers

IRVING, Texas--(BUSINESS WIRE)--April 27, 2004

Integrated Security Systems, Inc. (OTCBB:IZZI) today announced that its wholly owned subsidiary, B&B ARMR Corporation, received and shipped a major perimeter security order, start to finish, in three weeks in March for a critical Mid East facility. The project comprised a number of crash gates to secure a compound that houses US contractors that are assisting in an important infrastructure rebuilding program.

B&B ARMR was approached in early March by the joint venture of PAE-Louis Berger with the challenge of producing Model 450 and 712 crash gates for an expedited air shipment for this critical protection program. In just three weeks, B&B ARMR worked with its supplier partners to design and implement a logistics, manufacturing, and assembly program that resulted in the delivery of high security rated cantilever and crash gates.

"We had an extremely tight schedule and needed to secure commitment from all our supply partners. B&B ARMR readily accepted the challenge and dedicated a project team. It was just what this situation needed" stated Jeffrey Willis, Project Manager for Louis Berger. "In a project such as this, there is no such thing as close, we had to do everything with precision and B&B ARMR stepped up."

"In a situation where we can help with our country's efforts in the Middle East, we certainly understood the priority. Business as usual doesn't cut it anymore and we are proud of our team for this accomplishment," stated Ted Wlazlowski, Executive Vice President. "These gates are very large and quite complex and so a number of concurrent manufacturing and logistics processes needed to be coordinated quickly. Quality could not be compromised."

B&B ARMR's model 712/714 Crash Beam Barrier Gates are engineered and designed to protect at-risk access points and prevent forced vehicle entry or exit for industrial, commercial and institutional facilities including oil refineries, chemical plants, train yards, storage facilities, technical centers, nuclear facilities, embassies, military installations and government agencies. Available in sizes from 12' (3.66m) to 28' (8.53m), the crash beam barrier gates are capable of stopping a 10,000 lb (4,535.9 kg) vehicle traveling at 18 mph (29 km/hr). B&B ARMR's crash beams have been successfully crash tested for energy absorption capacity per U.S. Navy Specifications and Department of the Army.

B & B ARMR's 400 series cantilever gates have a minimum roadway opening of 12 feet (3.65 m) and a maximum opening of 26 feet (7.92 m). Towering at a height of 9 feet (2.74 m), the cantilever gate system is also an intimidating visual deterrent. Both the Model 400 and the model 410 are capable of stopping a 15,000 lb (6863.8 kgs) vehicle traveling 30 mph (48 km/h). Even more powerful, the Model 450 is capable of stopping a 15,000 lb (6863.8 kgs) vehicle traveling at 50 mph (80 km/h). Basic components of the cantilever gates include a motor side buttress assembly, cantilever gate leaf, receiver assembly, drive unit, and an electro-hydraulic locking mechanism. B & B ARMR's cantilever gates have been successfully crash tested to meet strict Department of State specifications and are individually inspected at time of final assembly and test.
