Fire damper actuators.Selection and integration.

2

Motorised fire dampers are shut-off devices that

prevent fire and smoke from spreading through

ventilation systems. In the event of a fire, they

protect people and tangible assets.

Fire dampers are equipped with a thermoelectric

tripping device. To prevent smoke from spreading,

they can also be triggered by smoke detectors.

They are powered by Belimo fire safety actuators.
