The VU120 is a rectangular fire resistant smoke evacuation damper with a fire resistance to 120 min. The normal position of this damper is closed. In case of fire, the blade opens thus enabling the evacuation of smoke.
The remote opening of the smoke evacuation damper enables smoke evacuation in case of fire, by setting off an internal spring in an NF24/SF24 (24V) system. The damper is closed when signals are sent to the servomotor. Once they are not received, the damper opens with the help of the spring.
