Automatic Opening Vents (AOV)
Smoke Ventilation Systems Designed to Protect Life
In many fire incidents, smoke inhalation poses a greater risk than flames themselves. Dense smoke can quickly block escape routes, reduce visibility and expose occupants to dangerous gases within minutes.
Automatic Opening Vents (AOVs) are designed to extract smoke from a building during a fire, helping to maintain clearer escape routes and improve conditions for safe evacuation. By releasing smoke through roof vents, windows or smoke shafts, AOV systems significantly reduce the risk to occupants and assist emergency services.
Fully Integrated & Compliant AOV Systems
AOV systems can be integrated with your fire alarm system or operate via a dedicated control panel. They can be activated automatically through smoke detection or manually via break-glass call points, depending on system design and building requirements.
At EFE Fire, we design, install and maintain AOV systems in accordance with current fire safety regulations and manufacturer standards. As a BAFE and NICEIC approved contractor, we ensure each installation is professionally commissioned, tested and documented.
