Clopay Corp. has introduced CrossingGard with ThreatProtect available on grilles, doors, or insulated doors through its Cornell and Cookson brands. CrossingGard with ThreatProtect creates lockdown zones within a building when a hostile event alarm is triggered. It also opens to allow freedom of movement in the event of a fire alarm. ThreatPro- tect controls are determined by end-user protocol, based on the build- ing design and emergency-management plans. The operating system uses two alarm inputs and a self-contained backup power supply to provide flexibility to assist in managing threatening situations. The product can help restrict an intruder from moving freely about the building, obstruct an intruder’s view or open egress for evacuation.
