Automatic Opening Ventilation

Automatic Opening Vents (AOVs) are essential systems used in buildings to significantly enhance fire safety and manage smoke. They operate via a motorised opening mechanism that automatically activates upon fire detection or a signal from a fire alarm system. Typically installed in windows, skylights, or smoke shafts, AOVs facilitate the escape of smoke and hot gases while allowing fresh air to enter, which minimises smoke spread, improves visibility for evacuation, and assists firefighters.

AOVs are a mandatory safety requirement, especially in multi-storey residential buildings, ensuring that escape routes remain clear and accessible. Compliance with UK building regulations, including Approved Documents B, F, and L, is crucial. Furthermore, AOVs must be certified to BS EN12101 and carry the CE marking. These systems can be deployed in single or multi-zone configurations, serving areas such as stairwells, smoke shafts, and corridors.
