Working conditions
Dampers are designed for smoke exhaust piping systems with underpressure max. 1500 Pa or
overpressure max. 500 Pa.
Dampers are designed for maximum air velocity 12 m.s.
Dampers are installed with the horizontal or vertical axis of the blades.
Dampers are intended for installation on air ducts and in/onto the walls where in the case of wall
installation, this wall with damper does not have fire resistance and therefore does not separate
two fire compartments.
Dampers are suitable for systems without abrasive, chemical and adhesive particles.
Dampers are designed for macroclimatic areas with mild climate according to EN 60 72133.
Temperature in the place of installation is permitted to range from - 20°C to + 50°C.
Design with actuating mechanism
SEDS-L is equipped by actuating mechanism Belimo BLE24 (BE24-12) for 24V supply or
BLE230 (BE230-12) for 230V supply. After being connected to power supply the actuating
mechanism displaces the damper blade into operation position "OPEN" or „CLOSED“ (according
to method of connection, see connection diagram). Running time is max. 60s. If is power supply
cut off, actuating mechanism is stopped in actual position. The crank handle supplied with the
actuator allows it to be operated manually. Signaling of the damper blade positions "OPEN" and
"CLOSED" is provided by means of two integrated, invariably set terminal switches.
