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.

Safety Notes

The actuator is not allowed to be used outside the specified field of application, especially in aircraft or in any other airborne means of transport.
Caution: Power supply voltage!
The actuator is adapted and mounted to the fire and smoke 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 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 electronic and electrical components and may not be disposed of with the household waste. Observe local regulations and valid laws.
