STI KIT-71100A-Y Yellow Back Box Kit for Stopper Station
Overview
The KIT-71100A-Y is a yellow back box assembly designed to house the Stopper Station emergency communication device and its universal button actuator. This is the structural and electrical foundation for fixed emergency call stations in lobbies, corridors, and public safety zones where you need a tamper-resistant, weather-protected enclosure. The unit operates on 9VDC and communicates via RS-232, making it a direct fit for existing Stopper system deployments that require standardized mounting and cable management.
Compatibility
This kit integrates with the STI Stopper Station emergency call system and supports universal button configurations. It is designed as the mounting and housing assembly for Stopper-series devices requiring a protective back box installation. Confirm your specific Stopper model version and button type with your system designer before ordering — the kit is engineered for Stopper Station hardware, not standalone use.
Installation Notes
Drill four 7mm masonry mounting holes to secure the back box frame to the wall. Use the cable gasket appropriate to your wiring system to seal unused cable entry holes and protect against moisture and environmental debris. Position the assembly centrally over the mounting surface and secure with the provided wall fixings. The yellow color aids visibility and identification in emergency situations. Ensure 9VDC power and RS-232 communication lines are routed through the gasket openings to maintain environmental protection.
