Automatic Opening Vents (AOVs) for smoke and heat control, protecting escape routes and supporting safe evacuation.
Why AOVs Matter
Automatic Opening Vents (AOVs) are life safety systems that release smoke and heat from a building during a fire. By clearing smoke from stairwells, corridors and escape routes, AOVs maintain visibility, reduce smoke inhalation risk, and allow occupants to evacuate safely while supporting firefighter access.
What an AOV System Includes
Depending on the building, an AOV system can include roof vents, high-level windows, louvres or automatically controlled doors.
When triggered by smoke detection or fire alarm signals, these vents open automatically to release smoke and hot gases, improving conditions along the escape route and limiting the spread of smoke through the building.
Keeping AOVs Compliant and Reliable
We inspect, maintain, and repair AOV systems to ensure they remain compliant and ready to perform. Our work covers control panels, actuators, local override points, interfaces with the fire alarm, and cause-and-effect logic. If your system is in fault, non-compliant, or poorly installed, we can diagnose the issue and bring it up to standard.
Service and testing in line with BS 7346-8 / BS 9999 principles.
