Trox Technik FKR-EU, Инструкция по установке и эксплуатации

Страница: 27 / 164


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


The adhesive tape in the installation area must NOT
be removed.

The product label must NOT be removed and must
remain visible.

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 FKR-EU, the structural proper-
ties of the supporting construction (wall / ceiling)
must be ensured by others, even in the event of a
fire.

Unless stated otherwise in the respective installation
details:
–
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 or ≥ 60 mm
with installation kit TQ from steel beams,
wooden beams or wooden ceilings with fire pro-
tection claddings. The fire-resistant cladding
(panel material) must be manufactured in
accordance with a national or European certifi-
cate and must lie against the supporting struc-
ture without cavities in the area of the fire
damper.

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 must be ensured by other, e.g.,
by switching off the fan or by mutual interlocking in
the case of the construction with a spring return
actuator.

As ducts may expand and walls may become
deformed in the event of a fire, we recommend
using flexible connectors for the following installation
situations:
- Lightweight partition walls
- Lightweight shaft walls
- Fire batt systems
The flexible connectors should be installed in such a
way that they absorb both tension and compression.
Flexible ducts can be used as an alternative.
Ducting must be installed in such a way that it does
not impose any significant loads on the fire damper
in the event of a fire. This can be achieved by a non-
straight duct, i.e. by bends or elbows, for example.
Be sure to comply with the relevant national guide-
lines and regulations.

The interior of the fire damper must be accessible
for maintenance work and cleaning. Depending on
the installation configuration it may be necessary to
provide inspection panels in the connecting ducts.
As an alternative to the inspection access, we rec-
ommend connecting the duct using flexible connec-
tors (fastened with hose clamp) or sliding connec-
tors.

Load-bearing components
Solid ceiling slabs and concrete beams, as well as
load-bearing solid walls are called load-bearing
components.
After installation

Clean the fire damper.

Remove transport and installation protection or the
prop, if any. In case of mortar-based installation this
protection must not be removed until the mortar has
hardened.

Test the function of the fire damper.

Make electrical connections.
Connecting duct and extension piece
It is possible to insert screws near the spigot for fixing.
Equipotential bonding
Flange construction

The flange of the fire damper can be used for equi-
potential bonding; no holes must be drilled into the
damper casing.
Spigot construction

The equipotential bonding is fixed, for example, with
suitable clamps. Alternatively, it is allowable for
drilled holes to be made near the spigot.
Thermal insulation
When using thermal insulation, especially for outside or
exhaust air, fully bonded panel insulation materials
made of elastomeric foams (synthetic rubber) can be
used (e.g. Armaflex Ultima from Armacell). Be sure to
comply with the relevant national guidelines and regula-
tions for combustible building materials and smoke for-
mation classes.
