    ® NORDfire | FDML General 1. Description Fire dampers are shutters in ducts of air-conditioning devices that prevent the spread of fire and combustion products from one fire segment to the other one. FDML multi blade fire dampers are in motorised design only with actuator and they have two main applications.

  • Page 4: Design

    ® NORDfire | FDML 2. Design 2.1 Design with manual control Design .40 and .50 Fire dampers are equipped with Belimo spring return actuators with thermoelectric activation device BAT. The spring return actuator types are BFL, BFN or BF depending on the damper size. (Further mentioned as „actuator“). After being connected to power supply 230V or AC/DC 24V, the actuator rotates the damper blades to the operating position “OPEN”...
