What is an AOV Window?

An AOV is short for “automatic opening vent” the AOV system was designed to create automatic air openings within an environment for smoke ventilation and safety.

Why do I need an AOV System?

An AOV system is used to control the ventilation when a fire occurs within a building. This is a mandatory building regulation which was made due to results of smoke inhalations when a fire or incident occurs, causing the automatic smoke vents to open.

When the detector or call point is activated, the AOV control system will open the actuators, vents or windows which creates ventilation. This clears the smoke within a building so people can leave.

What AOV system will I need to fit?

First you need to work out the building and how many zones you have which will need automatic opening vents for each item. Please follow our AOV system example below on how we would work out what a zone is:

1. You have 2 windows and 1 roof vent on the same floor when the alarm is triggered.

Due to the one floor and the multitude of items that need automatic openers, this is classed as one zone. First, you will need to add an AOV actuator which triggers the window and vents to automatically open when a fire alarm is triggered. If there is already an alarm system then there may be smoke detectors fitted you can use an AOV single zone to your fire system, that will help trigger the AOV actuators when the alarm is triggered. They will automatically close when the alarm is reset.

2. You have 3 floors with windows and vents on each floor.

This would be classed as 4 zones, you can use an aov multi zone panel which has options to open aov actuators on certain floors. Under this the vents will open on only the floors that the alarm is triggered, creating a chimney effect clearing the smoke. If zone 1 was triggered the other zones would also be triggered and a roof vent would open. All windows and vents will need actuators to link to your new or existing fire alarm.
