The isolating base senses and isolates short circuit faults on XP95 loops and spurs. The base is loop-powered, polarity sensitive and accepts the XPERT card to set the associated detector address.
In short circuit conditions, the integral yellow LED is illuminated. The detector associated with the base remains active under short circuit conditions. Up to twenty devices (detectors and XP95 interface units) may be installed between isolating bases.
