Installation
• The duct connected to the smoke damper must be supported or hung in such a way that the damper does not
carry its weight. The damper must not support any part of the surrounding construction or wall which could cause
damage and consequent damper failure.
• The damper driving mechanism can be placed on either side of the wall, however, it needs to be situated to ensure
easy access during inspection.
• According to the EN 1366-2 standard, the distance between the smoke damper bodies must be at least 200 mm.
• According to the EN 1366-2 standard, the distance between smoke damper and the adjacent wall/ceiling
and the smoke damper must be at least 75 mm.
• The S-SA2 smoke damper must be installed into a smoke and re partition structure in such a way that the damper
blade is located inside this structure in its closed position. To help you nd the suspension plane, a bendable hinge
is provided on the damper body. This condition does not apply for S-SA2L.
• The gap in the installation opening between the smoke damper and the wall/ceiling can be increased by up to 50%
of the gap area, or decreased to the smallest amount possible that still provides sufcient space for the installation
of the seal.
• The gap between the damper blade in the open position and the self-standing grill (when installed) must be at least
200 mm according to EN 1366-10. Otherwise, the damper must be tested together with the grill.
• The smoke damper must be earthed after being installed into or onto the duct.
• Lists of all permitted installation methods are provided on the following pages. Every method only applies to those
damper types that are listed in the corresponding paragraph’s heading.
