System Sensor B224BI-WH Plug-in Isolator Detector Base (White)

The System Sensor B224BI-WH is a white plug-in intelligent addressable isolator base for Select Series detector heads that helps keep an SLC loop operating during a short circuit. It isolates the shorted section from the rest of the loop, then automatically restores the loop when the fault clears, with up to 25 addressable devices typically isolated between isolator bases. Key Specifications: Type: Intelligent plug-in isolator detector base (Select Series, white) Core Function(s): Isolates an SLC short to prevent an entire communication loop from being disabled; automatically restores when the short is corrected Loop/Protocol: Intended for use in an intelligent addressable system on the SLC (supports Class A and Class B wiring) Power: 15 to 32 VDC; 450 uA standby max; 15 mA isolation current max Indicators/UI: Tamper-resist feature helps prevent detector removal without a tool Mounting: Mounting plate fits 4-inch square (with or without plaster ring), 4-inch octagon, 3.5-inch octagon, single-gang, and double-gang boxes Wiring: 18 AWG to 12 AWG System Compatibility: Used with compatible Select Series intelligent addressable plug-in detector heads on supported addressable SLC systems. Note: White (-WH) bases are suitable for use with FlashScan, Velociti, and LiteSpeed communications protocols only. Note: Replaces the previous model number B224BI.
