3/50 | FDR-3G…EX Description Atex fire dampers represent passive fire protection, designed with the help of compartmentalization to prevent the spread of toxic gases, smoke and fire. Standard fire dampers are designed and certified in accordance with EN 15650 and tested for EIS criteria according to EN 1366–2. Fire dampers together with their installation form an inseparable part of a fire resistivity rating.

4/50 | FDR-3G…EX • Inspection opening built-in • Great variety of installations rated up to EI120S Activation Types Manually Operated Fire Dampers By default, all manually operated fire dampers are supplied with a hand crank, optionally with microswitches. In case of fire, the fire damper is closes automatically after the melting of the thermal fuse.

11/50 | FDR-3G…EX Diagrams The pressure drop and A-weighted total discharged sound power level depend on the nominal diameter of the damper and air flow volume at different duct pressures. The type of activation does not influences the airflow parameter, therefore only one activation type is shown in the diagrams.

48/50 | FDR-3G…EX Operation Manual Warning To avoid injury, make sure to wear gloves and keep the blades movement area clear while manipulating the damper. NEVER OPEN THE INSPECTION LID WHEN THERE IS AIR FLOWING IN THE DUCT CONNECTED TO THE FIRE DAMPER! Fire Damper Functionality Check Manually Operated Activation Mechanism 1.
Page 49
49/50 | FDR-3G…EX Because to the need to perform a visual check of the damper’s internal parts, the inspection lid should be opened. For small sizes there is the possibility of removing the mechanism to perform the inspection. The removable mechanism always needs to be replaced into the damper with the damper blade being closed.
