What are Automatic Opening Vents?

Automatic Opening Vents (AOVs) are smoke ventilation systems that open automatically during a fire to help clear smoke from stairwells, corridors, and lobbies. They can be roof vents, window actuators, or shaft systems—typically controlled by a dedicated AOV panel and interfaced with the fire alarm.
