What Are Automatic Vent Openers (AOVs) For?

 

AOVs (Automatic Opening Vents) are designed to:

Automatically open windows, louvres, or roof vents in the event of a fire.

Extract smoke and hot gases, clearing escape routes like corridors, stairwells, and lobbies.

Improve visibility for evacuation and emergency services.

Lower temperatures to delay flashover and structural damage.​​

 

They are triggered by the fire alarm system or integrated smoke detectors, opening automatically when smoke is detected
