S-SA2L Installation
The S-SA2L smoke damper can be installed on “single” (tested according to EN 1366-9) or “multi” (tested according
to EN 1366-9) ductwork. If mounted on a duct classied with lower re resistivity, the re resistivity of the S-SA2L
smoke damper will be decreased to the duct level.
This section does not depict duct hanger rules as those are dependent on the weight of the duct itself and must be
statically approved.
Smoke control dampers can be suspended from solid ceiling slabs using adequately sized threaded rods.
When using anchors in the ceiling, use a re-rated anchor (with suitable a re rating certicate).
IMPORTANT: The suspension of the damper must be loaded only with the weight of the damper.
The connection surfaces must be attened and clean before the re resistive coat is applied.
Suspension systems longer than 1,5 m require re-resistant insulation.
Fixing the S-SA2L Smoke Damper
Each S-SA2L smoke damper has a connection ange with openings in the corners (Fig. 27).
For damper widths greater than 750 mm, another xing point in the middle of the widest side is added and must be
connected as per instructions in
Fig. 28 - Fig. 33.
