FIRE DAMPER - FD
WALL LIMIT
125 mm
The duct connected to the fire 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. It is recommended to connect the
damper to a
flexible connection on either end of the damper.
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.
•
Mounting is possible with the blade axis in horizontal or in
vertical position
•
The installation must comply with the tests that were
performed during certification
•
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
•
Operating temperature: 50 °C max
•

All dampers can be installed with the blade axis in a horizontal
position or a vertical position in all installation types except
installation remote from the wall and battery installation.
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 (except for installation with
Applique/MF1/MF2 installation frame).
To help you find the suspension plane, a bendable fixing bracket
is provided on the damper body (
the use of bendable fixing
brackets is not required to meet the classification
) and the red
tape is placed on the casing to mark the location of the wall
limit
(distance from wall limit to the end of fire damper is 125
mm)
. This does not apply for Applique/MF1/MF2 kit installations.
Check the operation of the fire damper before commencing
the installation!
INSTALLATION
The FD25/FD40 fire d amper i s a lways t ested i n
standardized support frames (both in a concrete wall
and in a flexible wall) in accordance with EN 1366-2:
2015 table 3/4/5. The results obtained are valid for all
similar support frames which have a thickness and/or
density and/or fire resistance similar or greater
than the one
test
ed
.
Always e
nsure the damper is sufficiently supported
