The Morley-IAS MI-D240CMO and MI-D240CMO-DIN control output modules are used with the Morley-IAS intelligent fire alarm control panels to provide management of 240Vac loads.
The modules are loop powered devices controlling an unsupervised double pole relay output with one normally open and one normally closed contact. The output relay is a bistable device, latching in either the on or the off state on command from the fire alarm control panel.
Each module 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. Each module is supplied with a built-in isolator for protection. However, to increase application flexibility individual isolators may be switched out as required.
