The MI-D2ICMO dual input/single output
modules are used with the Morley-IAS intelligent
fire alarm control panels to provide a dual input
circuit from external devices and a single relay
control output circuit.
Each input is continuously monitored for normal,
open circuit and alarm conditions. Any change
in the status of the input circuits is
communicated to the panel where the
appropriate actions may be undertaken. A single
pole volt free changeover relay is available for
control of external devices or circuits.
The MI-D2ICMO requires three addresses per unit
of the ninety-nine possible module addresses
available on a loop. It responds to regular
polling from the control panel indicated by a
pulsing LED every successful communication.
The MI-D2ICMO uses a unique mechanical design
allowing each module to be mounted either in a
wall box (M200E-SMB) or on a DIN rail (using
M200E-DIN). Irrespective of the mounting
method chosen, the address switch is both visible
and accessible for selection. To help engineers in
the maintenance and fault finding process, both
the LEDs and the address switches can be viewed
without having to remove the cover of the
mounting box. The LEDs, being multi colour,
provide diagnostic information regarding the
status of the output. For ease of installation,
testing and maintenance, the field wiring
terminals are of a plug in design.
