Standards and guidelines
– Construction Products Regulation
– EN 15650:2010 Ventilation for buildings – Fire
dampers
– EN 1366-2:1999 Fire resistance tests for

– EN 13501-3:2010 Fire classification of
construction products and building elements
– EN 1751:1999 Ventilation for buildings – Air

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 maintenance and inspection
refer to the installation and operating manual

1Functional 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.

Functional 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.

1Functional 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
(M375DD9).
Use in areas with potentially explosive
atmospheres (ATEX)
According to declaration of conformity
TÜV 11 ATEX 085420 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.

Functional description
Air transfer dampers are designed to shut off
openings for air transfer in fire resistant internal
walls and ceiling slabs.To prevent smoke from
spreading in buildings, it is extremely important
that the smoke is detected at an early stage. Duct
smoke detector Type RM-O-3-D is required to
control and trigger the air transfer damper.The
smoke detector operates on the principle of light
scattering and detects the smoke regardless of its
temperature so that the fire dampers can be
closed before the release temperature is reached.
The thermoelectric release mechanism of the
spring return actuator also triggers the closure of
the damper blade.When the release temperature
(72 °C) is reached, the temperature sensor in the
airflow interrupts the supply voltage to the spring
return actuator.The spring return in the actuator
causes the fire damper to close (power off to
close). A second temperature sensor monitors the
ambient temperature. If the supply voltage fails,
the damper closes. Air transfer dampers consist of
an FK-EU fire damper, an RM-O-3-D duct smoke
detector with general building inspectorate
licence Z-78.6-125, a spring return actuator
(24 V AC/DC or 230 V AC) with two integral limit
switches, and cover grilles on both ends.
Special characteristics
– Easy electrical connection
– Integration into the central BMS with
TROXNETCOM
– General building inspectorate licence: Z-6.50-
2031
For further and up-to-date information, including
the general building inspectorate licence and the
operating and installation manual, please refer to

design of our fire dampers please refer to the
Easy Product Finder design programme on our
website.
Note
– Approved only for internal walls and ceilings
– The B and H dimensions of units installed in
ceilings must not exceed 500 mm
– Not to be connected to ducts in ventilation and

Correct use

FK-EU
– DE/en
1Design information
– Approved only for use in ventilation and air
conditioning sytems
– If the fire damper is installed in a solid wall,
solid ceiling slab, lightweight partition wall or
shaft wall 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 FK-
EU (details upon request)
– 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.
– For further information relevant to design, in
particular information on installation situations,
please refer to the operating and installation
manual.
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:
– Use as an air transfer damper only in
compliance with licence no. Z-6.50-2031
– Do not use it in extract air systems in
commercial kitchens.
– A class of performance up to EI 180
(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.
