Automatic Opening Vent Panels (AOV & OV)


Smoke Ventilation

Smoke Ventilation for your building environment in the event of smoke detection via automatic opening vents (AOV). Systems are normally integrated into staircase Automatic Opening Vents (AOV) or an end of corridor Automatic Opening Vent (AOV) to provide the free area necessary for safe escape routes.

Systems can be linked to a range of inputs including; Smoke Sensors, Manual Call Points (Break Glass, Rocker Switch or Key Switch) and fire alarm systems.

All inputs can be wired into a central location via an AOV Control Panel eg. WSC 204, WSC204KP, WSC308, WSC316 or VCS-S1 Control Panels. Additional inputs for both Natural Ventilation and Day to Day ventilation can also be linked to the AOV Control Panels such as; Rocker Switches, Rain Sensors, Wind Sensors, Thermostats & Timers.

All controls are tested to current European EN standards.

Additional inputs for both Natural Ventilation and Day to Day ventilation can also be linked to the AOV Control Panels such as; Wall Mounted Rocker Switches, Rain Sensors and Wind Sensors.

All controls are tested to current European EN standards.
