Apollo 55000-812APO XP95 DIN-RAIL Zone Monitor with Isolator

The DIN-Rail Zone Monitor with Isolator powers and controls a zone of up to 20 Apollo Series 65 or Orbis fire detectors in a Discovery or XP95 loop.

Operation:

The DIN–Rail Zone Monitor is factory preset to return an analogue value of 16 when all detectors on the zone are in the quiescent state and 64 when a detector changes to the alarm state. The unit latches in the alarm state. A 5.1k end-of-line resistor is used to monitor cables for open and short-circuit faults. Alternatively, an active end-of-line monitor may be used in conjunction with diode bases and a capacitor of up to 50uF fitted at the unit wiring terminals. In either case an analogue value of 4 is transmitted during open or short-circuit faults.

The DIN–Rail Zone Monitor is fitted with a bi-directional short-circuit isolator and will be unaffected by loop short-circuits on either loop input or output. For IS applications use DIN-Rail IS Zone Monitor, part number 55000-798.

Key Features:

• Loop-powered
• Visible short-circuit and alarm
