MI/DCZRM Addressable Zone Monitor Module
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).
