Model ST-ABI-SCW is a SIL2 approved sensor mounting base featuring an integral short-circuit isolator which will detect and isolate short-circuits on the loop. When a short-circuit is detected during power up the unit will drop the power to the rest of the loop. The base is compatible with the ESP range of SIL2 approved sensors and does not require a loop address. A remote fire LED facility is provided when a sensor is attached to the base.
NOTE: A fitted sensor will still be powered when this device is isolating.
