Connecting S-SA2 to “multi” Ductwork Made of Boards
The S-SA2 smoke damper can be connected to “multi” ductwork made of calcium silicate boards tested according
to EN 1366-8. If mounted on a duct classied with lower re resistivity, the re resistivity of the S-SA2 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.
IMPORTANT: The interior of the S-SA2 smoke damper must remain accessible for maintenance.
Depending on the installation conguration, it may be necessary to create additional inspection panels
in the connecting ducts.
