Fire damper actuators.
Selection and integration.
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.

Connection to control cabinet
Actuator types
• Cables for motor and auxiliary switches wired directly to control cabinet.
• For 24 V actuators, the voltage drop over long lines should be noted. The voltage at the
actuator must be within the tolerance stated in the data sheet.
• Feedback of damper position by means of auxiliary switches.
Connection to automation station
Communication and control unit
BKS24-1B and plug socket ZSO-11
• For controlling and monitoring of a fire
