Key Features

• 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.
