Fire & Smoke Dampers

This device is used to prevent the spread of fire and smoke within the ventilation duct work.
Three types of Fire Dampers are available:
1) Motorized: On/ Off spring return actuator is used to close the damper blades by receiving signal from fire fighting system
2) Fusible link : Damper blades will be released and closed after the thermal fuse melts by the heat caused by the fire
3) Combined Motorized and Fusible link: the termal fuse is used as a backup of actuator for closing the damper blades in case of fire
