10A Single Zone Vent Interface Unit

The single zone vent interface is the most simple and user friendly solution on the market today. The unit is loop controlled and provides direct control of reversing polarity vents or 3 wire (drive open and drive closed vents)

The unit is provided (in standard format) with a 10.25A power supply unit with space for 17Ah batteries.

The vent interface units are wired to the same 2 core detection loop as the detectors, interfaces and fireman’s keyswitch units.

A radial circuit runs between the vent interface unit and the vent or damper.

Monitoring

The Vent Interface monitors the status of the EN 54-4 certified power supply unit for all required fault conditions. Cabling to the vent or damper is fully monitored for open and short circuits. All fault conditions are repeated at the control and indicating equipment.

Flexibility

By utilising the control panels powerful cause and effect programming the vent interface unit can also provide full environmental control of dampers and vents with fully adjustable opening times for different modes.

If required damper open and close status can be monitored and these signals repeated at custom mimic indicator panels (if required)

Customisable

Vent Interface Units can be provided to control separate environmental dampers. Multi zone units are available to provide a centralised wiring location.
