Smoke release systems are designed to open all windows in an emergency.

Ventilation card for local opening of a single window / room allows opening and ventilation of up to 2 windows simultaneously by a single breaker. This allows for dual use of motors installed in the various spaces and allows for spot opening according to the wishes of those who use the spaces in which the motors are installed.

During a fire alarm the button will not be active and control will move to the smoke release hub only.

At the end of the fire alarm it will again be possible to use the button for ventilation.
