Zone Monitor with Isolator 55000-845

The XP95 Zone Monitor with Isolator powers and controls the operation of a zone of up to 20 Orbis/Series 65 Apollo fire detectors from the Apollo loop and is for indoor use only. Features The XP95 Zone Monitor with Isolator returns a preset analogue value when all detectors on the zone are in quiescent state. A different value is returned when a detector changes to the alarm state. The Zone Monitor with Isolator latches in the alarm state. The Zone Monitor with Isolator is fitted with a bi-directional short circuit isolator and will be unaffected by loop shortcircuits on either the loop input or loop output. Two LEDs, one red and one yellow, are visible through the front cover of the enclosure. The red LED is illuminated to indicate that a fire alarm condition has been detected on the zone wiring. The yellow LED is illuminated whenever the built-in isolator has sensed a short-circuit loop fault.
