Marine DIN-Rail Zone Monitor

Operation

This unit needs to be installed in a suitable enclosure and secured using end stops, part no 27447-528 or equivalent. The Marine DIN–Rail zone monitor is factory pre-set 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 5.1KΩ 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 50μF fitted at the unit wiring terminals. In either case an analogue value of 4 is transmitted during open or short-circuit faults. The Marine 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.

EMC Directive 2014/30/EU

The Intelligent Twin Switch Monitor complies with the essential requirements of the EMC Directive 2014/30/EU, provided that it is used as described. A copy of the Declaration of Conformity is available from Apollo on request. Conformity of the Intelligent Twin Switch Monitor with the EMC Directive, does not confer compliance with the directive on any apparatus or systems connected to them.

Product Information

The Marine DIN–Rail Zone Monitor powers and controls the operation of a zone of up to 20 conventional fire detectors from a loop of XP95 addressable detectors and ancillary devices.
