FDS-3G…OF
Rectangular Fire Damper FDS-3G
Description
Overflow 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. FDS-3G...OF fire dampers are to be used as Air Transfer Grilles - installations without
connected ductwork. The installations are listed and described in their User Manual. By default, all Overflow fire
dampers are supplied with an manual mechanism or actuator mechanism, optionally with smoke detector. FDR-3G...OF
is equipped on both ends with Grilles that together with the duct extensions cover blade overhangs.
Manually Operated Fire Dampers
By default, all manually operated fire dampers are supplied with hand crank, optionally with micro switches. In case of
fire, the fire damper is closes automatically after the melting of the thermal fuse. After the closing of the damper
blade, it is mechanically locked in the closed position and can only be opened manually. The actuating mechanism is
activated when the temperature of the air in the duct reaches 74°C and the damper closes within 10 seconds after the
melting of the fuse.
Actuator Operated Fire Dampers
By default, all actuator operated fire dampers are supplied with an actuator with micro switches. A fire damper
equipped with a spring return actuator can be closed with command from the building management system, or after
the breaching of the thermoelectric fuse. Actuator operated fire dampers are standardly equipped with a
thermoelectric fuse, that activates the closing of the damper after the reaching or exceeding of the ambient
temperature of 72°C. The actuator power circuit is interrupted and its spring closes the damper blade within 20
seconds.
The activation mechanisms are removable and are interchangeable, for example an actuator operated mechanism
instead of a manually operated mechanism.
Highlights
• Activation types with fitted smoke detector
• Construction with included Grilles
