Installation in the Duct Made of Sheet Metal
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 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 must 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). Suspension systems longer than 1,5 m require fireresistant insulation.
IMPORTANT:
Flexible connection between duct and S-BM2 is needed, when connected to metal duct.
The suspension of the damper must be loaded only with the weight of the damper.
The interior of the S-BM2 smoke control damper must remain accessible for maintenance,
it may be necessary to create additional inspection panels in the connecting ducts.
The maximum resistivity for in duct installation is EI120S with pressure level 2 (-1000 Pa … 300 Pa)
