MI/DCZRM

The MI-DCZRM addressable zone monitor module allows a zone of non-addressable devices to communicate with a Morley-IAS protocol analogue addressable system. As a result existing non-addressable zones can be integrated into a Morley-IAS protocol system.

The module monitors a zone of two-wire non-addressable devices. Each MI-DCZRM uses one of 99 available module addresses on a loop. A fault signal will be transmitted to the panel in case of an open circuit or short circuit on the non-addressable zone wiring or when the external fault input is pulled low (can be used for power supply monitoring). A flashing LED indicates that the module is in communication with the control panel. The LED latches steady on alarm (subject to current limitations).

The non-addressable zone can be powered from the analogue communication loop or from an external power supply. Where the non-addressable zone is powered from an external power supply, the communication loop is fully isolated from the non-addressable zone and from the power
supply.

The zone monitor module replaces the MI-CZME but can be mounted onto a DIN rail. It can also be powered from the addressable loop and allows integration of non-addressable zones into an addressble system. This module enables non-addressable devices to be monitored by Morley-IAS protocol analogue addressable fire alarm control panels.

The maximum recommended number of non-addressable devices that can be used with the MI-DCZRM is 20
