Installation on the Horizontal Duct
S-BM2 smoke control damper can be installed on “single” (tested according to EN 1366-9) or “multi” (tested according
to EN 1366-8) ductwork. If mounted on a duct classified with lover fire resistivity, the fire resistivity of S-BM2 smoke
control damper will be decreased to the duct level. This section is not depicting 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 fire rated
anchor (with suitable fire rating certificate).
IMPORTANT:
The suspension of the damper must be loaded only with the weight of the damper.
The connection surfaces must be flattened and clean before the fire resistive coat is applied.
Suspension systems longer than 1,5 m require fire-resistant insulation.
