Maintenance
– The functional reliability of the fire damper
must be tested at least every six months;
this has to be arranged by the owner of the
ventilation system; functional tests must be
carried out in compliance with the basic
maintenance principles stated in EN 13306
and DIN 31051. If two consecutive tests,
one 6 months after the other, are successful,
the next test can be conducted one year later
– A functional test involves closing the damper
blade and opening it again; with a spring return
actuator this can be done via remote control
– Fire dampers must be included in the regular
cleaning schedule of the ventilation system.
– For details on functional tests, maintenance
and inspection refer to the installation
and operating manual

Functional description
In the event of a fire, fire dampers shut
automatically to prevent the propagation
of fire and smoke through ductwork to adjacent
designated fire compartments. In the event of a
fire, the damper is triggered at 72 °C or at 95 °C
(use in warm air ventilation systems) by a fusible
link.The release mechanism is accessible and
can be tested from the outside. Both regular
limit switches and explosion-proof limit
switches are available for zones 1 and 2
(gases, mists, vapours) and for zones 21 and 22
(dusts) to indicate damper blade positions.

Fire dampers
General information FKR-EU
1Functional description
The spring return actuator enables the motorised
opening and closing of the damper blade;
it can be activated by the central BMS.
In the event of a fire, the damper is triggered
thermoelectrically at 72 °C or 95 °C
(use in warm air ventilation systems).
As long as power is supplied to the actuator,
the damper blade remains open. If the supply
voltage fails, the damper closes (power off to
close). Motorised fire dampers can be used to
shut off ducts.The torque of each actuator is
sufficient to open and close the damper blade
even while the fan is running.The spring return
actuator is fitted with limit switches that can be
used for capturing the damper blade position.

Functional description
The fire damper is used as a shut-off device to
prevent fire and smoke from spreading through
ducting in areas with potentially explosive
atmospheres.The fire damper is suitable for
supply air and extract air systems in potentially
explosive atmospheres. For details on the
operation of the fire damper refer to the operating
and installation manual and to the technical data
in the supplementary operating manual
(A00000038482).
Use in areas with potentially
explosive atmospheres (ATEX)
According to declaration of conformity
TÜV 13 ATEX 128437 X, the fire damper
may be used in the following areas with
potentially explosive atmospheres.
The ambient temperatures and types
of release and actuation specified
in the technical data are binding.

Fire dampers
Correct use FKR-EU
1Design information
– Approved only for use in ventilation
and air conditioning systems
– If the fire damper is installed in solid walls
and ceiling slabs, timber stud walls as well
as shaft walls with a lower fire resistance class
than that of the fire damper, the fire resistance
class of the wall or ceiling slab applies
also to the FKR-EU
– Loads imposed on the casing may impair the
function of the fire damper. Install and connect
the damper in such a way that no loads
will be imposed on the installed damper.
– For particular applications it is recommended
that flexible connectors are used to connect
rigid ducting to the unit.
– Inspection accesses are provided
for maintenance and cleaning work
– For further information relevant to design,
in particular information on installation
situations, please refer to the operating
and installation manual.
K4 – 1.1 – 8 03/2017 – DE/en
Incorrect use
Never use the fire damper
– without specially approved attachments
in areas with potentially explosive atmospheres
– as a smoke control damper
– outdoors without sufficient protection
against the effects of weather
– in atmospheres where chemical reactions,
whether planned or unplanned, may cause
damage to the fire damper or lead to corrosion
If this fire damper is used in Germany:
– Do not use it as an air transfer damper.
– Do not use it in extract air systems
in commercial kitchens.
– A class of performance up to EI 120
(ve, ho,i↔o)Scanonlybeachieved
with ducts connected on both ends,
or with a duct on one end and a cover grille
on the other end.

K4 – 1.1 – 16
Flexible connector with
flange for FKS-EU-FL
Application
– For information on how to limit such loads
please refer to the guideline regarding fire
protection requirements on ventilation systems
(Lüftungsanlagen-Richtlinie, LüAR)
– As ducts may expand and walls may become
deformed in the event of a fire, we recommend
for the following applications using flexible
connectors when connecting the fire damper to
rigid ducts: installation into lightweight partition
walls and into lightweight shaft walls
– Flexible connectors should be installed in such
a way that both ends can compensate
both tension and compression
– Flexible ducts can be used as an alternative
– For certain nominal sizes extension pieces
may be required, see table
– The fixing holes in the flexible connectors
and extension pieces match those in the fire
damper flanges (applies only to FKR-EU-FL)
– Flexible connectors are supplied separately
and can are fixed by others
– Flexible connectors
are also available separately
Materials and surfaces
– Flexible connectors made of galvanised steel
(FKR-EU-FL only) and fibre-reinforced plastic
– Fire resistance properties to 4102; B2
– Extension piece made of galvanised sheet
steel (and powder-coated silver grey,
RAL 7001, when used with powder-coated (1)
and stainless steel (2) dampers)
