MI -D21CMO
  • General
  • Feature
  • Specification
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.
