Fire-Lite B501-IV 4" Standard European Flangeless Mounting Base, UL/ULC Listed, Ivory

Optimize your fire detection installations with the Fire-Lite B501-IV 4 in. standard European flangeless mounting base. As a detector accessory from Fire-Lite Alarms by Honeywell, this ivory base delivers a secure, professional mounting solution that reduces installation time and helps maintain tidy, unobtrusive aesthetics in commercial and institutional environments. The flangeless, 4" footprint accommodates common European mounting layouts while SEMS screws simplify field wiring, minimizing labor and rework.

Built for reliability, the B501-IV is UL/ULC-listed and supports operating voltages from 15 to 32 VDC with a low 170 µA maximum standby current—helping preserve system resources and support longer battery life in monitored applications. The mechanical locking feature prevents unintended detachment of the sensor head, enhancing tamper resistance for security-conscious sites. Compatible with Fire-Lite H365 series addressable heat detectors, this base is ideal for fire alarm, security, surveillance and facilities monitoring projects that demand dependable, code-compliant components. Add the B501-IV to your next installation for faster commissioning and long-term operational confidence.
