  • Page 3: Overview

    FDS-3G Overview Description 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 damper together with its installation form an inseparable part of fire resistivity rating.
  • Page 4 FDS-3G Overview Activation Types Manually Operated Fire Dampers By default, all manually operated fire dampers are supplied with manual control, optionally with micro switches and electromagnets. In case of fire, the fire damper is closed automatically. Depending on the version, the damper closes either after the melting of the thermal fuse or by means of remote activation through an electromagnet in impulse connection.
  • Page 5 FDS-3G Overview Design Fire dampers have casings made from galvanized sheet metal. Blades from non-asbestos insulants have a rubber seal for cold smoke and an intumescent seal, that expands in a fire situation. Material Composition The product contains galvanized sheet metal, calcium silicate board, fireproof carbon fiberglass, polyurethane foam and ethylene-propylene rubber.

    FDS-3G Diagrams The pressure drop and A-weighted total discharged sound power level depend on the nominal width and height 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.
