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

Apollo XP95 Zone Monitor Unit with Isolator – 55000-845APO is a loop-powered device designed to power and control a zone of up to 20 Apollo Series 65 or Orbis Fire Detectors from a Discovery or XP95 loop. Operating between 17–28V DC, this indoor-only unit is supplied with a surface-mounting backbox. It provides clear status indication via two LEDs: a red LED signals a fire alarm on the zone, while a yellow LED indicates a short circuit loop fault detected by the built-in isolator.
