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.
