What is an AOV?

AOV is simply an abbreviation for “Automatic Opening Vent”. An AOV system is a control system designed to vent air or smoke for use in natural & smoke ventilation.

So why do I need an AOV system?

AOV control systems are used mainly to control the ventilation of smoke in a fire. Changes to building regulations were made due to the results of investigations into smoke inhalation.
When a detector or call point is triggered an AOV control system will open actuators, windows or vents to create ventilation. This clears smoke for people leaving the building and vents smoke out of the area that has been triggered.
