The factory-fitted electric motor and gas struts on the Smoke Vent roof window ensure it opens automatically in the event of a fire, quickly extracting excessive smoke and heat. The maximum position of the window sash is reached within 60 seconds when the smoke detector detects smoke in the atmosphere, the break-glass point is shattered or the fire/smoke detect button on the control unit is pressed. The control unit has a battery backup system that ensures an emergency power supply for up to 72 hours, so in the event of a power failure the window will still operate.
The Smoke Vent roof window is a centre pivot smoke-ventilation roof window for sloping roofs between 15 and 60 degrees. It's also CE-marked in compliance with the European standard EN 12101-2 for smoke and heat exhaust ventilators.
