System Sensor B224BI-IV Plug-in Isolator Detector Base (Ivory)

The System Sensor B224BI-IV is an ivory plug-in intelligent addressable isolator base for Select Series detector heads that helps keep an SLC loop operating during a short circuit. The base isolates the shorted section of the loop from the rest of the circuit and automatically restores normal operation when the fault clears. Key Specifications: Type: Intelligent plug-in isolator detector base (Select Series, ivory) 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: Intelligent addressable SLC base used with compatible plug-in detector heads; 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 junction boxes Wiring: 18 AWG to 12 AWG System Compatibility: Used with compatible Select Series intelligent addressable plug-in detector heads that mount to the B224BI-IV base on supported addressable SLC systems. NOTE: Ivory (-IV) bases are suitable for use with FlashScan/Velociti/LiteSpeed, and CLIP communications protocols.
