Technical drawing - AOV Smoke vent

Smoke vent technical drawing showing version for fitment to builder's upstand and version with PVC kerb which can be fitted directly to the roof deck. Automatic Opening Vents (AOVs) or AOV Smoke Vents are designed to automatically extract smoke in the event of a fire. This range of Smoke vents fully opens in less than 60 seconds which creates a draught to ventilate smoke out of the building. When a fire is detected in the building either by smoke detectors, heat detectors or the fire alarm the AOV Smoke Vent receives a signal to open. The open vent creates an escape route for smoke and hot gases which helps stop smoke accumulating and spreading through the building. Smoke vents can be controlled manually by fire fighters which allows them to help control and extinguish building fires.
