Fire-Lite B200SR-LF-WH Low Frequency Intelligent Sounder Base, White

Designed for faster, more reliable audible notification in sleeping and high-risk areas, the Fire-Lite Alarms by Honeywell B200SR-LF-WH Low Frequency Intelligent Sounder Base delivers proven life-safety performance for addressable detector installations. The low-frequency 520 Hz tone is clinically shown to improve wake response, making this detector base ideal for hotels, healthcare, dormitories and residential-occupancy sections of commercial buildings. Engineered for system flexibility, the base supports either the ANSI Temporal-3 three-pulse pattern or a continuous tone, and produces greater than 85 dBA at 10 ft when powered at 24 V. The B200SR-LF-WH isolates the external 24 VDC power connection from the SLC communication loop (15–32 VDC), reducing electrical interaction and improving reliability across large security and monitoring networks. Compatible with System Sensor 7351 detectors and retrofit-friendly with B501-Series bases, it simplifies upgrades and reduces installation downtime. Specify the B200SR-LF-WH for NFPA-compliant alarm systems that demand dependable notification and easy integration into fire, security, and surveillance deployments.
