The MI-DMMI and MI-DMM2I monitor modules
are used with the Morley-IAS intelligent fire
alarm control panels to provide a single or dual
input circuit from external devices.
Each input is continuously monitored for normal,
open circuit and alarm conditions. Changes to
the status of the input circuits are communicated
to the panel where the appropriate actions may
be undertaken.
The MI-DMMI requires a single address and the
MI-DMM2I two addresses 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-DMMI and MI-DMM2I use 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 mountng 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.
