4. check the damper’s functionality as per the chapter “Fire Damper Functionality Check” before you install the fire
damper. This procedure prevents the installation of a damper that has been damaged during transportation or
handling.
Installation rules
• 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 placed so as to
ensure easy access during inspection. When the damper is fitted with smoke sensor, the damper must be rotated so
that the sensor is on highest posisition.
• According to the standard EN 1366-2, the distance between the fire damper bodies must be at least 200 mm. This
condition does not apply for tested distances. Therefore Wet and Soft installations are approved for smaller distances
under condition that the resulted resistivity is reduced to EI90S.
• The distance between the wall/ceiling and the fire damper must be at least 75 mm. This condition does not apply for
tested distances. Therefore Wet and Soft installations are approved for smaller distances under condition that the
resulted resistivity is reduced to EI90S.
• The fire damper must be installed into a fire partition structure in such a way that the damper blade in its closed
position is located inside this structure. A bendable hinge is provided on the damper body which represents a plane
where supporting construction begins.
• For each resistivity the minimum thickness of a its supporting construction cannot be decreased as per EN 1366-2 at
least 200 mm from the installation opening.
• The gap in the installation opening between the fire 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 sufficient space for the installation of
the filling.
IN ACCORDANCE WITH EN 15650, EACH FIRE DAMPER MUST BE INSTALLED ACCORDING TO THE INSTALLATION
INSTRUCTIONS PROVIDED BY THE MANUFACTURER!
