STI Stopper II® with Horn and Clear Spacer - Custom - STI-1130CR

STI STI-1130CR Emergency Exit Stopper with Horn and Clear Spacer

Overview

The STI-1130CR is a retrofit exit stopper device combining an integrated horn with a clear spacer plate—designed to flag unauthorized egress attempts while preserving emergency protocol visibility. The horn activates on unauthorized exit, signaling monitored personnel and access control staff. The clear spacer accommodates custom facility labels or evacuation placards, keeping exit routes unambiguous even when the alarm sounds. This matters in warehouses, data centers, and secure facilities where exit routes must remain legible under stress and audible alert conditions.

Compatibility

The STI-1130CR retrofit-mounts to standard push-bar exit devices and access control strike assemblies. Confirm mounting hole spacing and strike type (fail-safe or fail-secure) match your existing hardware before ordering. Works in single-door and multi-door access control layouts. Verify your control panel's output capacity supports the horn's electrical draw—check panel specifications against device power requirements to avoid overload.

Installation Notes

Secure the spacer plate using fasteners appropriate to your door frame material (verify material type before fastener selection). Orient the horn speaker toward the monitored zone to ensure audible coverage. Mount wiring through existing access control conduit where possible to minimize surface runs and maintain code compliance. Test horn operation and label visibility under actual facility lighting before final commissioning—confirm the spacer plate does not obstruct door operation or emergency egress clearance.
