S-SA2

Smoke control dampers are designed for mechanical or natural smoke and heat extract systems. Its function is to extract toxic gases, smoke and fire or provide a supply of fresh air to fire compartments. Smoke control dampers are fitted with an actuator without a spring; therefore they have two safety positions, “open” and “closed” and require power even in the event of fire.

• AA – automatic activation (sets the safety position within 60 seconds). No thermal insulation around the actuator needed.

• Multi – usage in compartments classified as “multi” Can be used also in compartments classified as "single"

• Pressure level 3 (-1500 Pa … 500 Pa)

• Casing leakage according to EN 1751, class C

• Blade leakage according to EN 1751, class 3

• Lightweight sheet metal construction

S-SA2 and S-SA2L smoke dampers are CE certified according to EN 12101-8:2011. Tested according to EN 1366–10:2011 + A1:2017 and classified according to EN 13501-4:2016. The smoke damper together with its installation form an inseparable part of the fire resistivity rating

• S-SA2: Wall Mounted Smoke Control Damper - AAmulti Rectangular smoke control damper without mesh for installations in the wall and ceiling between single & multi and multi & multi compartments

• S-SA2L: Duct Mounted Smoke Control Damper - AAmulti Rectangular smoke control damper with a silicone gasket and mesh -fitted extension for blade overhangs. Suited for installations on the vertical and horizontal multi compartment ducts.

S-SA2 and S-SA2L has a galvanized sheet metal casing. The damper blade is made of calcium silicate boards. The closed damper is sealed by an active intumescent sealing to avoid the spread of heat and smoke. Flanges are used for the connection of the damper to a duct. S-SA2L has an additional frame of calcium silicate board on the casing in the blade area and a duct extension fitted with galvanized sheet metal mesh.
