Only Aluminum Door to Meet U.S. Embassy Forced Entry Test

CompuDyne Corp. (Nasdaq:CDCY) an industry leader in sophisticated security products, integration and technology for the public security markets, today announced that it has achieved a long standing objective in attack protection - development of an architectural style aluminum door that can meet the extremely rigorous forced entry test under U.S. State Department standards. This product, manufactured under the Norshield brand by the company's Attack Protection segment, is the first aluminum door ever to achieve this level of protection.

Until the introduction of this product, attractive architectural style aluminum doors were not an option when a building required serious protection from bullet, blast and attack threats. Unattractive, utilitarian steel security doors were the only certified protection available. Now building entryways can be safe and attractive.

The Attack Protection segment, under the Norshield brand, has successfully tested and certified it's NS7000 series aluminum door and entrance system for forced attack in accordance with the Department of State Standard SD-STD-01.01. The extruded aluminum doors and windows are the first of their kind to be tested to multiple threat scenarios and can provide tested and laboratory certified protection from a variety of individual and combined threats including bullets, bomb blast impact, and physical assault. Norshield's NS7000 system has successfully passed several physical standards including UL752 Level 1 - 8 bullet resistance, ASTM F1233 Class IV physical assault, FEMA 361 impact resistance, GSA Level C & D bomb blast protection, and DOS SD-STD-01.01 forced entry resistance.

The protection afforded by the NS7000 series products are available in any single level of protection or can be combined for protection against multiple threat scenarios (bullet resistant plus bomb blast plus forced attack).

Norshield brand security aluminum doors and windows are designed to blend with existing architecture and to have the look and feel of conventional aluminum storefronts and doors, thereby providing an exceptionally high level of security while providing a transparent line of defense. The range of size, finish and protection offerings will excite the design and architectural community, while the flexibility of the products will likely result in significantly expanded opportunities to install these unique entrances. These products will find applications not only internationally on U.S. embassy and military projects but also domestically on courthouses, federal office buildings, U.S. border stations, and other "high value" targets.
