Schlage 742 Emergency Break Glass Assembly with Sonalert Horn

Designed for fast, unmistakable emergency release, the Schlage 742 Emergency Break Glass Assembly with Sonalert Horn gives facilities a robust, tamper-resistant solution for lockdown and access control situations. Ideal for laboratories, secluded testing areas and perimeter-controlled doors, this assembly delivers both audible (80 dB sonalert) and visual (LED) alerts to ensure security teams and building occupants are alerted immediately. The stainless steel surface-mount housing installs in a standard 3-gang enclosure and connects to fail-safe electronic locking systems with a 30V DC input, making integration with existing monitoring and access control systems straightforward. The break-glass concept minimizes misuse versus pull stations and includes four replacement lens disks and clear signage for ongoing maintenance and compliance. Engineered by Schlage for commercial security and surveillance environments, the 742 unit supports centralized monitoring while providing essential local emergency release capability.
