    Hochiki ESP Short Circuit Isolator Base in Ivory or White

    This short circuit isolator base is a 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.

    These bases are compatible with the ESP range of 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.
