Maintenance and operation
Fire dampers FDC are used for prevention of fire spread trough the ventilation ducts and
between fire sections. Fire dampers consist of steel sheet casing, calcium silicate damper
blade, damper blade mechanism outside of the airflow and a manual, electromagnetic
or electric actuator.
Fire damper casing is made out of galvanized steel sheet. Variants produced from
stainless steel and powder coated steel are also available. Calcium silicate blade is
equipped with brass bearings and seals made out of polyurethane and elastomer rubber.
Fire dampers FDC25 are produced up to size d315 and have 25 mm thick damper blade.
Fire dampers FDC40 are produced in sizes from d355 till d800 and have 40 mm thick
damper blade. FDC25 fire dampers are equipped with R25 manual mechanism and
FDC40 fire dampers are equipped with R40 manual mechanism.
Manual spring return mechanism is equipped with thermal fuse that is triggered
automatically when the temperature inside the duct reaches 72 °C. It can also be
activated manually by the push of the button on the mechanism.
Additional equipment for manual mechanism include end contact switches for damper
position signalling. Electromagnetic actuators feature spring return mechanism with
electromagnet for remote activation. Additional equipment for electromagnetic
mechanism include end contact switches for damper position signalling. Rearming of
the electromagnetic actuator is manual.
Fire dampers with electric actuators are equipped with Belimo actuator drives in 24V or
230V versions. Activation of fire dampers equipped with electric drives can be via 72 °C or
95 °C thermal fuse or remotely via control signal. Rearming of the electric fire damper
can also be done remotely via control signal. All electric actuators are equipped with end
switches for position signalling.
ATEX rated versions of fire dampers can be delivered with Schischek 24V/230V electric
actuators that are rated for installation in explosive atmosphere areas. All fire dampers
are tested according to the EN 1751 for airtightness and retain class 2 leakage on the
closed damper blade and class C on the casing air leakage.
