S-RA1
Installation DMV
Vertically Oriented Damper, in the Metal Duct
The S-RA1 smoke control damper can be installed on these types of ductwork:
• “single” ductwork from sheet metal tested to EN 1366-9 or with higher density/thickness.
• builders work ducts (created on site).
This section does not give information about duct hanger rules. These rules are related to the weight of the duct and
they must have static approval.
Hang the smoke control dampers from solid ceiling slabs with rods that have a thread. The dimension of these rods
must be sufficient for the weight of the damper.
If you use anchors in the ceiling, make sure that you use a fire- rated anchor (with the correct fire rating certificate).
1. Prepare the duct connections:
a. Clean the ductwork connection surfaces.
b. Follow ductwork manufacturer instructions and if needed apply sealant on the ductwork connection surfaces.
2. Follow instructions in "Product Handling" section.
3. Perform damper's functionality check (see "Operation Manual" section).
CAUTION:
• Make sure that the closest hanger is placed not further than 150 mm from the duct connection.
• If the hanger system is longer than 1,5 m, fire-resistant insulation is necessary (see hanger manufacturer instruction).
• Make sure that it is always possible to access the smoke control damper internally for maintenance. If necessary,
make inspection panel in the connecting duct.
• Duct with lower resistivities will decrease the fire resistivity of smoke control damper.
• The maximum fire resistance for in-duct installation is EI120 with pressure level 2 (-1000 Pa … 300 Pa).
Installation Distances
The minimum distance between the damper body and the wall or ceiling must be 75 mm (refer to Standard EN
1366-2). The minimum distance between two damper bodies installed in separate ducts must be 200 mm.
