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 MIDMM2I 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.
