fire damper is used as a shutoff device to prevent fire and smoke from
spreading through ducting. During normal operation the damper blade is open to
enable air passage through the ventilation system.
If the temperature increases in the event of a fire, the damper blade closes.
Release is triggered at 72 °C ( 95 °C in warm air ventilation systems). If the
damper blade closes due to a temperature increase (i.e. in the event of a
fire), it must not be reopened.

fusible link
Functional description
In fire dampers with a fusible link, damper closure is triggered by the
fusible link. If the temperature inside the fire damper rises to 72 °C or 95
°C, the fusible link triggers a coil spring mechanism. The coil spring
mechanism then causes the fire damper to close.
As an option, the fire damper can be either supplied or subsequently fitted
with one or two limit switches. The limit switches can signal the damper blade
position to the central BMS or fire alarm system. One limit switch each is
required for damper blade positions OPEN and CLOSED.
Functional description
The spring return actuator enables the motorised opening and closing of the
damper blade; it can be activated by the central BMS. Motorised fire dampers
can be used to shut off ducts on a regular basis. As long as power is supplied
to the actuator, the damper blade remains open. The spring return actuator
closes the fire damper when one of the following events occur:
Temperature in the fire damper > 72 °C or > 95 °C Ambient temperature outside
the release mecha-
nism > 72 °C The power supply is interrupted (power off to close)
As standard, the spring return actuator is equipped with limit switches that
can be used to indicate the damper blade position.

Functional description
If the duct smoke detector detects smoke, the spring return actuator closes
the damper blade. This prevents smoke from being transferred via ductwork into
adjacent fire compartments even before it reaches a temperature that would
trigger the thermoelectric release mechanism.
As long as power is supplied to the actuator, the damper blade remains open.
The spring return actuator closes the fire damper when one of the following
events occur:
The duct smoke detector detects smoke Temperature in the fire damper > 72 °C
Ambient temperature outside the release mecha-
nism > 72 °C The power supply is interrupted (power off to close)
The duct smoke detector must be installed by others in a rectangular duct.
Alternatively, the installation can be carried out on site in a circular duct,
in a T-piece. The duct smoke detector must always be placed at the top.
Deviating arrangements are possible, provided that the specifications of the
general building inspectorate licence of the duct smoke detector are observed.

release mechanism with fusible link
Functional description
Upstream shutters of air transfer units prevent fire and smoke from spreading
in buildings. The thermal release mechanism closes the upstream shutter of the
air transfer unit when the release temperature of 72°C is reached. Smoke can,
however, spread below this temperature.
The upstream shutter of the air transfer unit consists of the FKR-EU fire
damper with a thermal release mechanism for 72°C and with cover grilles on
both sides, but without a duct smoke detector.
The following applies to Germany: If fire dampers with a purely mechanical
shut-off element are to be used as an upstream shutter of an air transfer
unit, the local building regulations must be observed. Usually the use of such
upstream shutters of air transfer units is restricted to pressure differential
systems.

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 protection (if any) until installation is
complete.
26
Fire damper FKR-EU
Installation
General installation information
Control elements, electric actuator and inspection access panel must remain
accessible for maintenance.
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. 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
141 .
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 condensation 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 properties 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 elements 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 protection claddings. The fire-resistant cladding
(panel material) must be manufactured in accordance with a national or
European certificate and must lie against the supporting structure 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 nonstraight duct, i.e. by bends or elbows, for example. Be sure
to comply with the relevant national guidelines 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 recommend connecting the duct using flexible connectors (fastened
with hose clamp) or sliding connectors. 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 equipotential 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 regulations for combustible building
materials and smoke formation classes.
Fire damper FKR-EU
27
Installation
General installation information
Insulation is non-hazardous in terms of fire safety if the following
requirements are met:
the insulation does not impair the function of the fire damper,
The fire damper remains accessible. The inspection accesses and product
sticker remain
accessible. The insulation does not penetrate walls or ceilings.
Extension pieces
To ensure that the fire damper can be connected to the ductwork after
installation even if the wall or ceiling is fairly thick, you should extend
the fire damper with a suitable extension piece (attachment or extension by
others) on the installation side Ä Chapter 6 `Accessories’ on page 137 .
Installation positions
The fire damper may be installed so that the damper blade shaft is horizontal
or vertical or in all intermediate positions (0 360°).
Fig. 11: Thermal insulation

dripping), around the perimeter, actuator and release mechanism, inspection
accesses and product sticker must be accessible 9.2 Extension piece or duct Up
to EI 120 S
Note: The installation situation shown is representative of all supporting
constructions.
The following applies to Germany: In Germany, only insulation materials with a
fire behaviour of at least C – s2, d0, may be used according to the
specifications of the MVV TB (since 2019/1). This requirement is met by
Armaflex Ultima insulation material from Armacell, for example. The applicable
local building regulations must be observed. For notes on the use of
elastomeric foams, see Ä 7 .
Fig. 12: Installation positions and distances
a Distance between two fire dampers; see Ä 26 . The distance also depends on
the installation situation and is given in the installation details.
If a duct smoke detector is installed in the connected duct, it must be
positioned at the top, regardless of the installation position. Deviating
arrangements are possible, provided that the specifications of the general
building inspectorate licence of the duct smoke detector are observed.
For installation in the UK please note:
The final connection between the fire damper and the HVAC ductwork should
include a break-away joint, which will allow collapse of the ductwork during a
fire without disturbing the integrity of the fire damper.
Breakaway or flexible joints (e.g. flexible connectors) should incorporate materials, fixings, clamps, etc, that are manufactured from a non-fire resistant material with a low melting point such as aluminium, plastic, etc.

Installation
General installation information
Perimeter gap “s1” With mortar-based installation the perimeter gap
“s1” must not exceed 225 mm (wall and ceiling). The perimeter gap »s« must be
large enough so that mortar can be filled in even in case of thicker walls or
ceilings. Be sure to close larger wall openings or holes beforehand and in a
suitable way, i.e. depending on the type of wall. When there are larger
openings in the solid ceiling slabs, the dampers must be encased in concrete
when the ceiling section is created. The gap must be large enough so that
mortar can be filled in. We recommend a gap of at least 20 mm (note the
constructively required minimum installation opening size, e.g., for the
flange construction). Reinforcement should meet structural requirements.
Fig. 15: Perimeter gap 1 FKR-EU 2.1 Mortar s1 Perimeter gap Maximum gap widths
are based on EN 15882-2. Larger gaps do not have an adverse effect with regard
to fire protection and are in our opinion not critical.
Mortar-based installation
Cover all openings and control elements of the fire damper (e.g. with plastic)
to protect them from contamination.
If the wall thickness is >115 mm , extend the fire damper on the installation
side with an extension piece or a spiral duct.
Push the fire dampers into the installation opening in a centred manner and
secure them. The distance from the operating side to the wall/ceiling slab is
370 mm for the spigot construction and 342 mm for the flange construction.
Connect extension piece or duct if required.
In case of mortar-based installation, the open spaces between the fire damper
casing and the wall or ceiling slab must be closed off with mortar. Entrapped
air is to be avoided. The mortar bed depth should be equal to the thickness of
the wall but must be at least 100 mm.
If you install the fire damper as the solid wall or ceiling slab is being
completed, perimeter gap »s1« is not required. The open spaces between the
fire damper and the wall must be closed off with mortar; for installation into
solid ceiling slabs, concrete can be used. Reinforcements should meet
structural requirements.
The mortar bed depth should be equal to the thickness of the wall. If trim
panels with appropriate fire resistance are used, a mortar bed depth of 100 mm
suffices.

Installation
General installation information
Installation with installation kit
For installation without a mortar-mix, the installation kit TQ can be used
(only FKR-EU in spigot construction).
The installation kit is assembled on the fire damper at the factory. Fixing to
the wall / ceiling slab is carried out according to the respective
installation details.
The installation is carried out centred in the installation opening.
For installation near the floor or ceiling, professionally shorten the cover
plate of the installation kit on one side.
Fixing to the wall / ceiling slab is carried out according to the respective
installation details.
Installation with fire batt
The distance from the operating side flange to the wall or ceiling has to be
370 mm for the spigot construction and Flange construction 342 mm.
Fire batt systems consist of two layers of mineral wool slabs, gross density
140 kg/m³.
Apply fire-resistant sealant to the cut faces of the mineral wool slabs and
fit them tightly into the installation opening. Seal any gaps between the
mineral wool slabs and the installation opening, gaps between the cut faces of
cut-to-size pieces, and gaps between slabs and the fire damper by applying
fire-resistant sealant or coating. Use only sealant or coating that is
suitable for the fire batt system.
Apply ablative coating to the mineral wool slabs, joints, transitions and any
imperfections on the coated mineral wool slabs; coating thickness 2.5 mm.
Fix fire dampers on both sides of the wall, see Ä 136 .
If the wall/ceiling is fairly thick, you must use additional layers of mineral
wool slabs on side A.
Fire batt systems are not suitable for use below flexible ceiling joints.
