5.2 Safety notes regarding installation
Sharp edges, sharp corners and thin sheet metal
parts
CAUTION!
Danger of injury from sharp edges, sharp cor-
ners and thin sheet metal parts!
Sharp edges, sharp corners and thin sheet metal
parts may cause cuts or grazes.
– Be careful when carrying out any work.
– Wear protective gloves, safety shoes and a hard
hat.
5.3 General installation information
NOTICE!
Risk of damage to the fire damper
– Protect the fire damper from contamination and
damage.
– Cover openings and release mechanism (e.g.
with plastic) to protect them from mortar and
dripping water.
– Do not remove the transport and installation pro-
tection (if any) until installation is complete.

Control elements, electric actuator and inspection
access panel must remain accessible for mainte-
nance.

Loads imposed on the casing may impair the func-
tion of the fire damper. Install and connect the
damper in such a way that no loads will be imposed
on the installed damper. Ducts of combustible or
non-combustible materials may be connected to fire
dampers if the ducts have been installed straight
and without any torsion.

Before installation: Perform a functional test, then
close the fire damper
Ä
160 .

The adhesive tape in the installation area must NOT
be removed.

Protect the fire damper from humidity and conden-
sation as they will damage the fire damper.

The construction variants with stainless steel or
powder-coated casing and additionally with an
impregnated damper blade meet more critical
requirements for corrosion protection.

When installing the FKRS-EU, the statics of the sup-
porting construction (wall / ceiling) must be ensured
by others, even in the event of a fire.

Unless stated otherwise for a particular installation
situation:
–
Each fire damper must be installed in a separate
installation opening. The distance between two
fire dampers is
≥
200 mm.
– The distance from load-bearing structural ele-
ments is
≥
75 mm.
– A maximum of two fire dampers must be
installed in a single installation opening.
– Fire dampers are allowed to be in mortar-based
installation at a distance of
≥
40 mm from steel
beams, wooden beams or wooden ceilings with
fire protection claddings.

If several fire dampers are used on the same duct,
the following has to be ensured: If one damper
closes, the maximum permitted upstream velocity
for the other fire dampers that remain open must not
be exceeded. This has to be ensured by others; it
can be ensured, for example, by switching off the
fan or by using actuators with limit switches that
ensure that not too many dampers close at the
same time.
