    Apollo XP95 Zone Monitor Unit with Isolator – 55000-845APO

    The Zone Monitor powers and controls the operation of a zone of up to 20 Apollo Series 65 or Orbis Fire Detectors from a Discovery or XP95 loop. The Zone Monitor with Isolator is loop powered and operates at 17–28V DC with protocol pulses of 5–9V.

    The Zone Monitor with Isolator is supplied with a backbox for surface mounting, and is for indoor use only. 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. The backbox is a polycarbonate moulding.
