Churches Fire & Security can help with the installation and servicing of Automatic Opening Vents (AOV), which are critical fire safety systems designed to provide effective smoke and heat ventilation in the event of a fire. By allowing smoke and hot gases to escape, AOVs help keep escape routes clear, improve visibility, and reduce the risks associated with smoke inhalation, making them an essential component of fire safety in all buildings.

CHURCHES FIRE & SECURITY ARE EXPERTS IN AUTOMATIC OPENING VENTS, ENSURING PEOPLE CAN SAFELY ESCAPE A BUILDING IN THE EVENT OF FIRE.

What Are Automatic Opening Vents?

An Automatic Opening Vent (AOV) is a specially designed ventilation system that automatically opens in the event of a fire to allow smoke, heat, and gases to escape. These vents are typically installed in ceilings, windows, or roof spaces to help direct smoke and heat outside, ensuring that the internal environment remains safer and more breathable.

AOVs are typically integrated with fire alarm systems or smoke detectors and are triggered automatically. They are often installed in buildings where smoke accumulation could obstruct escape routes or hinder emergency response efforts.

Key Benefits of AOV Systems

Improved Fire Safety: By allowing smoke and hot gases to escape quickly, AOVs help ensure that escape routes remain clear and accessible.
Enhanced Visibility: In case of a fire, smoke-free or smoke-reduced environments help to maintain visibility, allowing people to evacuate more safely.
Protects Property: AOVs help reduce the spread of smoke and heat, minimising damage to the structure of the building and its contents.
Compliance with Regulations: AOV systems are often required by law in certain types of buildings, especially those with large open spaces, high ceilings, or complex layouts.
Assists Firefighters: By reducing the amount of smoke in the building, AOVs make it easier for firefighters to access the fire and manage the situation safely.

How AOVs Work

Automatic Opening Vents are generally connected to a building’s fire alarm or smoke detection system. When smoke or heat is detected, the AOVs open automatically to allow smoke, heat, and gases to escape. This helps to maintain breathable air and visibility for building occupants and allows easier access for emergency services.

AOVs can be installed in various locations, including high ceilings, atriums, corridors, and other spaces where smoke might accumulate. The system can be activated manually or automatically, depending on the configuration and fire safety needs of the building.

Fire Safety Regulations

The British Standard for maintaining Automatic Opening Vents (AOVs) is BS: 7346-8. To comply with this standard, AOVs must be serviced annually by a competent person, and tested weekly, monthly, and every six months.

We recommend AOVs and electrically operated OVs should be tested once a month using the manual controls to ensure they are working as intended. In addition, once a year, a full test should be performed which includes checking the functionality of smoke detectors and AOV controls.
