Fire-lite B224RB-IV Detector Base with Relay Ivory

Product Description

The FIRE-LITE B224RB-IV is a plug-in detector relay base designed for use with 200 Series fire detection devices. It provides a single Form C contact relay that enables control of auxiliary functions tied to the fire alarm system. Common applications include door closure activation and elevator recall. The base accepts a plug-in detector and integrates directly into the wiring loop without additional hardware. Fire alarm technicians and life-safety contractors install this base as part of a compliant detection layout. Its relay output allows the system to trigger building control functions automatically upon alarm activation.

The B224RB-IV is suited for commercial and light-industrial fire alarm installations where auxiliary device control is required at the detector level. It is used in applications where door holders, elevator controls, or other building systems must respond to a fire alarm signal. The plug-in design simplifies installation and detector replacement without disturbing field wiring. The ivory finish is standard for commercial fire alarm installations.
