Addressable Micro Zone Monitor Unit – MIU872

An extensive range of micro interfaces are available to support the Eaton range of control panels, providing solutions for most design requirements.

The MIU872 is a single zone input, soft addressed, micro interface, incorporating integral short circuit isolators.

It is fully compatible with the current range of Eaton intelligent addressable control panels. It is suitable for interfacing a zone of up to 20 conventional Eaton detectors onto a Eaton intelligent addressable control panel.

It will operate with any Eaton conventional detector in configuration with a schottky diode type base (CDBB300).

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

• Plug and play no hard addressing required
• Easy to expand a system using existing wiring
• No external short circuit isolator required

Features

• Quick and simple to install
• Accepts a zone of Menvier conventional detector heads and callpoints (detectors must be connected via the Cooper CDBB300 mounting base)
• Only takes a single address
• Input monitored for open and short ground trouble
• Active end of line monitoring
• Built in short circuit isolator

Installation

1. Suitable for use with any Eaton conventional
detector(except for D200 range).
2. Connections suitable for single strand fireproof cable up to 2.5mm2 .
3. Loop and input cable screen must be connected to interface earth terminals.

Note: No addressing of the interface is required (see control panel operation for details)
