Addressable Micro Single Channel Output Unit (Reset on Reset) – MCOM-R

The (MCOM-R) gives a 5 second pulse on reset, and is used for connecting/resetting beam detectors.
An extensive range of micro interfaces are available to support our range of control panels, providing solutions for most design requirements.

The MCOM is a single output, soft addressed, micro interface, incorporating integral short circuit isolators. It is extremely compact and therefore ideal for incorporation into other equipment.

The MCOM is fully compatible with the current range of Eaton intelligent addressable fire control panels.

It is suitable for switching low voltage (24V dc at 1A maximum), via a set of non latching relay contacts.

It is suitable for switching HVAC control circuits, plant shutdown control circuits, fire door closure etc.

INNOVATIVE DESIGN

Small size

Get devices and panels talking

 

The flexibility of the Micro Interface range means that the units can be used in a range of different applications. The interfaces can be ideal for tall buildings, and act as a connection message to other devices that feedback device status to control panels, and can activate devices. 

They can be ideal for use in tall buildings that have extractor fans to filter out any smoke from fire. The output unit will receive feedback from the control panel and can act as a switch to activate a fan when there’s a fire. The input unit will then feedback to the panel whether the fan is active or if there are any faults. 

Small in size, clever in design

Eaton’s range of fire system micro interfaces combines compact size with easy installation. Featuring no requirement for hard addressing, the units are small enough to connect through a single strand fireproof cable up to 2.5mm².

Benefits

• Quick and simple to install
• No hard addressing required (Plug and play)
• Compact size
• Programmable by Eaton site installer software as technical input/non fire input

Features

• Soft Addressed
• Integral short circuit isolater
• Single address
• Suitable for monitoring:
– Flow switches
– Non fire inputs
– Auxillary panels
• Up to 200 units per loop

Installation

1. Suitable for switching 24V dc control circuits (fire door retainers etc).
2. Connections suitable for single strand fireproof cable up to 2.5mm2.
3. Loop and output cable screen must be connected to interface earth terminals.
4. The relay output is a set of change over, non-latching, volt free contacts which are non monitored.
Note: No addressing of the interface is required (see control panel operation for details)
