Fire-Lite B224RB-WH Relay Base, 6.2" Diameter, White

Put dependable control and simplified installation at the heart of your fire and security system with the Fire‑Lite Alarms by Honeywell B224RB‑WH relay detector base. Designed as a low-power, surface-mount detector base, it converts a standard smoke detector into a monitored relay output for applications like elevator recall, door control and auxiliary signaling. The B224RB‑WH includes a Form C contact relay with selectable short (60–100 ms) or long (6–10 s) activation timing, and operates on 32V DC for efficient integration with existing fire alarm control panels. Its 6.2" diameter footprint and 1.6" profile allow neat installation over common junction boxes while the mechanical locking feature secures the detector head against tampering — improving protection and reducing false alarms. Built for reliable monitoring and easy serviceability, this Fire‑Lite relay base helps installers and facility managers meet code requirements and maintain uninterrupted security and surveillance operations. Specify the B224RB‑WH for projects that demand robust relay control with minimal installation time — ideal for commercial, institutional, and multi‑tenant buildings.
