The xvent Hinged Smoke Ventilation Rooflight, hides its operating mechanisms within the framework so when you look up that clear view of daylight is preserved and the building aesthetics enhanced. The Glazing Vision xvent (AOV) rooflight has been tested and certified to BS EN 12101-2:2003 and cycled many thousands of times in order to meet European standards. On installation it is connected to the fire alarm system which if triggered will automatically open the unit to 140° for effective smoke ventilation. If connection to the fire alarm panel is lost it will automatically open and should the fire alarm system fail completely, the integrated thermostat will trigger the unit to fire position should the internal temperature reach 72°.
