SMOKE CONTROL DAMPERS
INSTALLATION
FDSD smoke control damper is always tested in standardized
support frames in accordance with EN 1366-2: 2015. The results
obtained are valid for all similar support frames which have a
thickness/density/fire resistance similar or greater than the one
of the tests.
The duct connected to the smoke control 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
placed so as to ensure easy access during inspection.
The smoke control 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.
The gap in the installation opening between the smoke control
damper and the wall can be increased by up to 50% of the
gap dimension, or decreased to the smallest dimension
(B + 80 x H + 80)
•
The installation must comply with the tests that were
performed during certification
•
The FDSD smoke damper can be connected to ducts that
have been tested to EN 1366-9 and EN 1366-8. Also, the
smoke damper can be connected to fire-resistant ducts
that have been tested to EN 1366-1
•
Avoid any obstruction of the moving blade by the
connected ducts
•
The class of air-tightness is maintained in case the
installation of the damper is made in accordance with the
technical manual
•
For indoor use only
•
If the damper is installed in a wall of a lower fire resistance
class, the damper itself will have a lower fire resistance
class
All dampers have to be installed with the blade axis in a
horizontal position. To help you find the suspension plane, a
bendable fixing bracket is provided on the damper casing and
the red tape is placed on the casing to mark the location of
the wall limit
WALL LIMIT
125 mm
(distance from wall limit to the end of smoke control damper
is 125 mm).
Check the operation of the smoke control
damper before commencing the installation!
