Apollo XP95 addressable sensors base with isolator.

Apollo XP95 addressable detector base with isolator.

The isolating base detects and isolates short-circuit faults on the system loop. The base is loop-powered, polarity-sensitive and accepts an XPERT card, which sets the address of the associated device.

In the event of a short circuit, the base's integrated yellow LED indicator lights up. The fire detector fitted to the base remains active during a short circuit. Power and signals to the affected section of the loop are restored automatically once the fault has been cleared.
