MOUNTING INFORMATION
INSTALLATION IN SOLID WALLS
•
Installation in solid walls (shaft walls, shafts, ducts and fire
walls) made of, for example concrete, masonry according
to EN 1996 or DIN 1053; solid plaster board walls according
to EN 12859 or DIN 18163; apparent density ≥ 450 kg/m³
and wall thickness W ≥ 150 mm.
•
Installation with horizontal damper leaf.
•
Circumferential gaps "s" must be filled completely with
mortar of categories M2.5 to M15 according to EN 998-2,
NM II to III DIN V 18580 (previously: MG II to III according
to DIN 1053) or fire protection mortar of the correspon-
ding grade or with concrete suitable for the wall type. The
minimum gap size s
min
is 50 mm. If the fire damper is in-
stalled during the construction of the wall, the gaps "s" can
be omitted. The mortar bed depth has to be designed ac-
cording to the minimum wall thickness and may not be less
than this thickness.
•
The distance between the fire dampers must be min. 200
mm.
•
Distance to the bearing adjacent components (wall / solid
ceiling) is minimum 75 mm.
INSTALLATION IN SOLID CEILINGS
•
Installation in solid ceilings, for example made of concrete,
foam mortar; apparent density ≥ 500 kg/m³ and ceiling
thickness D ≥ 150 mm.
•
Installation with full mortar lining (circumferential gaps "s"
must be filled completely with mortar of category M15 ac-
cording to EN 998-2, NM II DIN V 18580 (previously: MG III
according to DIN 1053) or fire protection mortar of the cor-
responding grade. The minimum gap size smin is 50 mm. If
the fire damper is installed during the construction of the
ceiling, the gaps "s" can be omitted. The mortar bed depth
has to be designed according to the minimum ceiling thick-
ness and may not be less than this thickness.
•
The distance between the fire dampers must be min. 200
mm.
•
Distance to the bearing adjacent components (wall) is mi-
nimum 75 mm.

CONNECTION OF VENTILATION DUCTS
The fire dampers must be connected to the ventilation ducts
of the ventilation system either on one or on both sides. For
one-sided connections, finishing protective grating made of
non-combustible material (EN 13501-1) must be provided on
the respective opposite sides. The fire dampers can be
connected both to non-combustible and combustible
ventilation ducts.
The local regulations or national standards on ventilation
systems (in Germany e.g. LüAR) apply.
No inadmissible forces may affect the fire damper and space-
enclosing components especially in case of fire and impair
their fire resistance time. The required expansion joints
(flexible connecting pieces) must be designed as flammable,
elastic connecting pieces made of at least standard
inflammable materials (EN 13501-1) and installed between the
fire damper and ventilation duct. Flexible part of the
connecting piece (polyester fabric) must have the minimum
length of l
min
= 100 mm in the mounted state, this gives a
mounting dimension of approx. L = 160 mm. As an alternative,
instead of installing flexible connecting pieces, flexible
ventilation ducts made of aluminium can be connected.
Ventilation ducts must be suspended separately.
