Installation D1V, D2V - Vertically Oriented
Damper, On the 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 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.
1.Prepare the duct connection or opening - clean and flatten the connecting surface.
2.Apply fire resistive coat (F5) on the connection surfaces.
3.Place the damper on the profile hanger.
4.Connect the damper to ductwork with boards (8) create collars and overlap the connection.
5.Fix the collar covering to the damper and ductwork with nails or pins (F4) as per duct system manufacturer
instructions.
IMPORTANT
• The suspension of the damper must be loaded only with the weight of the damper.
• Dimension of opening must be created according to details of each type and thickness of connected duct.
• The fire resistivity of S-BM2 smoke control damper must be decreased to the duct performance.
• The maximum resistivity for in duct installation is EI120S with pressure level 2 (-1000 Pa … 300 Pa)
Installation Distances
According to the EN 1366-2 standard, the minimum distance from the wall or ceiling to the damper body is 75 mm.
For multiple crossings through a fire resistive wall, 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 resistive wall/duct.
