This window is a gravitational smoke ventilation system and is used to help expel the excess of smoke and heat during a fire. Additionally, the system enables daily ventilation and allows light into the room.
The FSR is equipped with an electric motor, which opens the window sash when one of the following occurs:
- When smoke is detected in the atmosphere
- When the glass alarm is shattered.
Once either of these actions occur, an electric signal from the control unit opens the sash.
This smoke ventilation window has been manufactured and certified according to harmonised standard EN 12101-2:2003.
The FSR is usually installed in stairways.
