Willow Fire & Security completed an AOV annual service at the top of a stairwell in Acton, West London, ensuring the building’s smoke ventilation system remains fully operational and compliant. The service included inspection and functional testing of the Automatic Opening Vent (AOV) roof vent, fireman’s override switch, associated smoke detection, and control interfaces.
All components were tested to confirm correct automatic and manual operation, with system status checks and resets carried out where required. Regular AOV servicing is essential for maintaining effective smoke clearance in stairwells, supporting safe means of escape and compliance with current fire safety standards. This project highlights Willow Fire and Security’s expertise in AOV servicing, smoke ventilation maintenance, and fire safety compliance across London.
