Smoke Ventilation & AOV frequently asked questions
Smoke control systems are one of the most important – and most misunderstood – parts of fire safety. Building owners, landlords and facility managers often ask us how AOVs work, when they’re required, and what maintenance is needed to stay compliant. To make things simple, we’ve answered the most common questions below, giving you clear, expert guidance on how smoke ventilation systems protect people, property and compliance.
What is an AOV and how does it work?
An Automatic Opening Vent (AOV) is a vent/window that opens automatically (via AFD Automatic Fire Detection or Manual Operation) in the event of fire; it allows smoke and heat to escape from staircases, corridors or roof spaces.
How often should AOV systems be tested and maintained?
Are AOVs required by law?
Requirements in many building types under UK building regulations (Approved Document B) and BS EN standards, depend on height, number of storeys, usage and evacuation route lengths.
