Fire Project recommend the Morley-IAS MI-DCMO control output module is used with the ZX series of intelligent control panels to provide either a single alarm circuit or Form C relay.

The MI-DCMO can be used to operate dry contacts for door holders, air handling unit shut down or other similar functions. Optionally the module can be used to supervise wiring to the output load providing monitoring of the external load voltage or power supply. If the monitored voltage falls below threshold, then a fault condition will be indicated.

Each MI-DCMO uses one 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. On command from the control panel the MI-DCMO will disconnect the supervision and connect the external power supply across the load. The disconnection of the supervision provides a positive indication to the control panel that the relay is activated.

The MI-DCMO has a built-in isolator which may be switched out if required
