MI-DCZRM Addressable Zone Monitor Module

The MI-DCZRM addressable zone monitor module allows a zone of nonaddressable 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 MIDCZRM 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 nonaddressable 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.Features: Connection of a zone of non-addressable detectors to an analogue addressable fire system Built in isolation allowing system installation in stages without loss of protection Monitors open circuit and short circuit TRI-Colour Status LED Zone powered from addressable loop wiring or external 24V PSU Remote reset of non-addressable zone Compatible with: Most non-addressable detectors IS non-addressable detectors Monitoring of external power supply External fault input CPD approval to EN54-17 and EN54-18, LPCB and VdS DIN rail mountable, consistent with all other modules Support for an extended power supply range as low as 18Vdc 60mA with an External PSU
