The fire damper can be installed into:
■
Solid wall construction made e.g. of normal
concrete/masonry or porous concrete with min.
thickness 100 mm.
■
Gypsum wall construction with min. thickness 100 mm.
■
Solid ceiling construction made e.g. of normal
concrete or pourous concrete, with minimum
thickness according to EN 1366-2.
■
Outside the wall/ceiling contruction. The duct and
damper must be protected by fire insulation.
■
If the damper is installed outside the fire separation
construction, a damper side A ≥ 800 mm and fire
resistance is EIS 90, VRM-Q reinforcement frame must
be used.
NOTE:
For lower fire resistance than EIS 90, VRM-Q
reinforcement frame is not necessary!
Examples of constructions for fire damper installation
"BUILT IN EDGE label" indicates the recommended edge of installation of a fire damper in the fire separating construction (wall/ceiling).
The damper must be installed so that the entire damper blade (in the closed position) is located in the fire separating construction
(wall/ceiling) and at the same time the actuating mechanism and inspection openings are freely accessible.
