Rectangular Smoke Dampers | 3 / 24 1396 - CPR - 0112 1396 - CPR - 0147 Description 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.
/ 24 | Rectangular Smoke Dampers Design 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.

/ 24 | Rectangular Smoke Dampers Dimensions Installation Distances The minimum distance from the wall or ceiling to the damper body is 75 mm. The minimum distance between two damper bodies is 200 mm. This applies for distances between the damper body and a nearby foreign object crossing the fire resistant wall. Damper clearances vary from the type of mechanism and their rotation. ≥75 A ≥210 ≥210 ≥75 ≥210 ≥200 A Fig. 3: Installation distances between damper bodies Tab.
Rectangular Smoke Dampers | 9 / 24 Dimensions and Overhang Make sure to avoid blocking the movement of a damper blade by keeping a minimal distance of 100 mm from the edge of the fully open blade to foreign objects and connected duct parts. R1 and R2 are the overhang of the fully open blade, including the seals and gaskets on the damper blade. 175 ø 6,2 80 10,5 × 11 R1 R2 125 W1 W×H (W + 60) × (H + 60) L = 300 Fig.

Rectangular Smoke Dampers | 13 / 24 Accessories D1-S-SA2 Duct Extension with Mesh for S-SA2 Description This accessory is available only for S-SA2 and must be used in situations where the duct ends right after the smoke damper installed in the wall or ceiling. Its mesh will cover the blade from any damage done by foreign objects during smoke extraction. Design This duct extension is designed in one length and is made of riveted sheet metal. The flanges fit the S-SA2 exactly.
