Smoke control dampers FSD are used in smoke extraction
systems for extraction of smoke gases or providing supply air to
one or more fire compartments. Smoke control dampers consist
of calcium silicate casing and calcium silicate damper blade.
Calcium silicate blade is equipped with galvanized steel shaft
and with seals. Seals are made out of silicon and of intumescent
material. Smoke control dampers FSD are produced in sizes from
200x240 till 1200x2040 mm and are equipped with Belimo
actuator in version 24V or 230V.
Activation of smoke control dampers equipped with
electric actuator can be via smoke detector or remotely via control
signal. Rearming of the electric smoke damper can also be done
remotely via control signal. All electric actuators are equipped
with end switches for position signalling.
In case of smoke detection the actuator is triggered by a signal.
The signal can come either from a duct smoke detector or
from a fire alarm system. FSD smoke control damper have two
safe positions: open and closed. Depending on the fire site
and the path of the smoke to be extracted, the safe position is
either “open” or “closed”. The blades of FSD move to the safe
position when receiving an automatically or manually triggered
control signal.
FSD smoke control damper complies with the requirements
of EN 12101-8, and is tested to EN 1366-10 and EN 1366-2.
Classification of damper is EI 120/90 (vedw-hodw, i↔o) S1000
C10000 HOT 400/30 MA multi.
