The MI-DCZRM addressable zone monitor module 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.
