System Sensor B200SR-LF-WH Retrofit Low Frequency Sounder Base

The System Sensor B200SR-LF-WH is a low frequency sounder base for Select Series plug in detectors, providing 520 Hz audible notification for sleeping areas that require NFPA 72 compliant low frequency signaling. It is compatible with Select Series intelligent detectors and B501BH style NAC circuits for retrofit applications, with tone (Temporal 3 or Continuous) selected locally by jumper. It mounts to a wide range of junction boxes for both new and existing installations. Key Specifications: Type: Low frequency sounder base for Select Series intelligent detectors Core Function(s): Provides 520 Hz low frequency audible notification for sleeping areas using a plug in detector base format Loop/Protocol: Notification circuit; 2 wire 16 to 33 VDC (VFWR) NAC, SLC wiring passes through to the installed intelligent detector Power: 16 to 33 VDC external supply; up to 65 mA at 33 VDC, 90 mA at 24 VDC, 125 mA at 16 VDC in alarm, approximately 1 mA maximum standby Indicators/UI: Produces at least 85 dBA at 10 feet at 24 VDC in continuous tone; Temporal 3 or Continuous pattern selected by on board jumper and driven by the connected NAC or power supply Compatible Detectors & Devices: FSP-951 – Intelligent photoelectric smoke detector FSP-951T – Intelligent photoelectric smoke and heat detector FSP-951R – Intelligent photoelectric duct detector head FST-951 – Intelligent 135F fixed thermal detector FST-951R – Intelligent rate of rise and 135F fixed thermal detector FST-951H – Intelligent 190F high temperature thermal detector FPTI-951 – Intelligent multicriteria photo thermal infrared detector FCO-951 – Intelligent multicriteria fire and CO detector FSCO-951 – Intelligent addressable CO detector FPC-951 – Intelligent photoelectric smoke and CO detector System Compatibility: Intended for use on compatible fire alarm control panels and notification appliance circuits that can supply 16 to 33 VDC (regulated or VFWR) and support System Sensor Select Series B200SR family sounder bases.
