Automatic opening vent systems are installed in buildings as an active fire protection measure. Opening vents allows smoke to dissipate out of a building providing a minor benefit to increase the visibility in the interior space to facilitate evacuation and aid manual firefighting efforts for a limited period of time. Most vents open via the operation of an electronic actuator, commanded from control gear that is interlinked with a fire alarm system. It is recommended that AOV systems are maintained on a six-monthly basis in order to ensure correct operation of vents upon activation of the fire alarm system. Franco Fire Detection offer Maintenance and Repairs of existing AOV systems ONLY. Please note currently we do not offer design solutions for AOV systems.
