Recommendation for application
Regular operational checks (open-close control of the fire damper) enhance the safety of people, animals, property and the environment. Unless other requirements are stipulated – e. g. in the damper manufacturer's operating instructions – Belimo recommends the performance of monthly operational checks. Fire damper actuators from Belimo are designed in accordance with service life specifications contained in the technical datasheet for regular operational checks. Notes for regular operational checks can be found in the European Product Standard for Fire Dampers (EN 15650) under "Maintenance information".
In the case of motorised fire dampers, remote operational checks are also possible, thus lowering operating costs.
The device must not be used outside the specified field of application, especially not
in aircraft or in any other airborne means of transport.
The actuator is adapted to and installed on the smoke control damper by the
damper manufacturer. For this reason, the actuator is only supplied direct to safety
damper manufacturers. The manufacturer then bears full responsibility for the proper
functioning of the damper.
The two switches integrated in the actuator are to be operated either on power
supply voltage or at safety extra-low voltage. The combination power supply voltage/
safety extra-low voltage is not permitted.
Cables must not be removed from the device
The device may only be opened at the manufacturer’s site. It does not contain any
parts that can be replaced or repaired by the user.
The device contains electrical and electronic components and must not be disposed
of as household refuse. All locally valid regulations and requirements must be
