Morley-IAS Addressable Output Module

Fire Projects use and recommend Morley-IAS MI-D240CMO and MI-D240CMO-DIN control output modules, which 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.
The modules are supplied by Fire Projects are in two individual mounting styles. The MI-D240CMO is supplied in a wall mounting enclosure complete with a grounding terminal. The MI-D240CMO-DIN is designed to mount on to standard 35mm “tophat” style DIN rail and is required to be installed within a suitable enclosure.
To help Fire Projects’s 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.
