1. Description
1.1 Fire dampers are shutters in ducts of air-conditioning devices that prevent spreading the fire and
combustion products from one fire segment to the other one by means of closing the duct in the
points of fire separating constructions.
Dampers blade automatically closes air duct using a shutting spring or an actuating mechanism
back spring. The shutting spring is started by releasing an initiation lever. The impulse for
releasing the lever can be either a manual one, a thermal one. The back spring of the actuating
mechanism is started when the thermoelectrical starting mechanism BAT is activated, when a
reset button on BAT is pushed or when a power supply of the actuating mechanism is stopped.
The damper is sealed with a silicon packing against smoke penetration after closing the blade.
At the same time, the damper blade is bedded in a material which enlarges its capacity and air
proofs the air duct.
Dampers have two inspection holes.

1.3 Working conditions
Right damper function is secured under the following conditions:
a) Maximum air circulation speed: 12 m/s
Maximum pressure dierence: 1200 Pa
b) The air circulation in the whole damper section must be secured as steady on whole
surface.
Operation of the dampers does not depend on the direction of air circulation. The dampers can
be located in an arbitrary position.
Dampers are suitable for systems without abrasive, chemical and adhesive particles.
Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3.
Temperature in the place of installation is permitted to range from -20°C to +50°C.
2. Design
2.1 Design with mechanical control
Design .01
Design with mechanical control with a thermal protective fuse which actuates the shutting device,
after the nominal start temperature 72°C has been reached. Automatic initiation of the shutting
device is not activated if the temperature does not exceed 70°C. In case that other start
temperatures are required, thermal fuses with nominal start temperature +104°C or +147°C can
be supplied (this requirement must be specified in the order).
Fig. 3 Design .01
Design .11
Design .01 with mechanical control can be complemented with a limit switch signalling of the
damper blade position "CLOSED". Cable is connected directly to limit switch.

ATTENTION:
Mechanisms are produced in four designs M1
to M5, dierence is only in size of inner spring,
which closes the fire damper. For the size of fire
dampers is always assigned the size of mecha-
nism - Tab 4.2.1. It is not recommended to use
dierent size of mechanism, than given by the
manufacturer, otherwise, there is a risk of fire
damper destruction.

2.2 Design with actuating mechanism
Design .40, .50
FDMQ is always equipped by electric actuating mechanism BFL, BFN, BF 230-TN or BFL, BFN,
BF 230-TN (further only "actuating mechanism"). After being connected to power supply AC/DC
24V or 230V, the actuating mechanism displaces the damper blade into operation position
"OPEN" and at the same time it pre-stretches its back spring. When the actuating mechanism is
under voltage, the damper blade is in the position "OPEN" and the back spring is pre-stretched.
Time needed for full opening of the flap blade from the position "CLOSED" to the position "OPEN"
is maximum 120 sec. If the actuating power supply is cut o (due to loss of supply voltage, or
pushing the reset button on the thermoelectrical starting mechanism BAT), the back spring
displaces the damper blade into the breakdown position "CLOSED". The time of displacing the
blade from the position "OPEN" to the position "CLOSED" takes maximum 20 sec. In case that
the power supply is restored again (the blade can be in any position), the actuating mechanism
starts to re-displace the damper blade into the position "OPEN".
A thermoelectrical starting mechanism BAT, which contains two thermal fuses Tf1 and Tf2, is a
part of the actuating mechanism. These fuses are activated when temperature +72°C has been
exceeded (the fuse Tf1 when the temperature around the damper and the fuses Tf2 when the
temperature inside the air-conditioning piping has been exceeded). After the thermal fuse Tf1 or
Tf2 has been activated, the power supply is permanently and irreversibly cut o and the actuating
mechanism, by means of the pre-stretched spring, displaces the damper blade into the
breakdown position "CLOSED".
Signalisation of damper blade position "OPEN" a "CLOSE" is provided by two limit switches.

4. Placement and Assembly
4.1 Fire dampers are suitable for installation in arbitrary position in vertical and horizontal passages
of fire separating structures. The damper assembly procedures must be done so that all load
transfer from the fire separating constructions to the damper body is absolutely excluded.
The back-to-back air-conditioning piping must be suspended or supported so that all load
transfer from the back-to-back piping to the damper flanges is absolutely excluded. The gap
between the installed damper and the building structure must be perfectly filled with approved
material all over its volume.
To provide the necessary space for access to the control device, all other items must be situated
at least 350 mm from the control parts of the damper. At least one inspection hole must be
accessible.
The damper must be installed so that the damper blade (in closed position) is situated in the fire
separating structure - marked by the label BUILD-IN EDGE on the damper body. If such solution
is not possible, the piping between the fire separating structure and the damper blade must be
protected according to the certified installation method, see Section 6.
During the installation and plastering process, the control mechanism must be protected
(covered) against damage and pollution. The damper body should not be deformed during
bricking in. Once the damper is built in, the damper blade should not grind on the damper body
during opening or closing.
The distance between the fire damper and the structure (wall, ceiling) must be 75 mm at the
minimum. If two or more dampers are to be installed in one fire separating structure, the distance
between adjacent dampers must be 200 mm at the minimum, according to EN 1366-2 paragraph
13.5. For admissible exceptions see Section 6.
Fig. 17 The distance between the fire damper and the construction
27
"Wall edge sticker" indicates the recommended edge of installation of fire damper into the fire partition structure (wall).
The damper must be installed so that the entire damper blade - in the closed position - is located inside the fire separating structure
(wall) and at the same time the control mechanism and inspection openings are freely accessible.

Fig. 18 Built in edge
“Wall edge sticker” indicates the recommended edge of installation of fire damper into the fire
partition structure (wall). The damper must be installed so that the entire damper blade - in the
closed position - is located inside the fire separating structure (wall) and at the same time the
control mechanism and inspection openings are freely accessible.
4.2 Installation opening dimensions
Fig. 19 Installation opening dimensions
4.3 Examples of fire damper installing
The fire damper can be integrated into a solid wall construction made e.g. of normal concrete/
masonry, porous concrete with minimum thickness 100 mm or into solid ceiling construction made
e.g. of normal concrete with minimum thickness 110 mm or porous concrete with minimum
thickness 125 mm. The fire damper can be integrated into a gypsum wall construction with fire
classification EI 120 or EI 90.
The fire damper can also be integrated outside the wall construction. Duct and the damper part
between the wall construction and the damper blade (labelled with BUILD IN EDGE on the
protective covering) must be protected with fire-fighting insulation.
If is damper installed outside a construction it is necessary to use reinforcement VRM.

separating constructions to the damper body is absolutely excluded. The back-to-back air-conditioning
piping must be suspended or supported so that all load transfer from the back-to-back piping to the damper
flanges is absolutely excluded. The gap between the installed damper and the building structure must be
perfectly filled with approved material all over its volume.
To provide the necessary space for access to the control device, all other items must be situated at least
350 mm from the control parts of the damper. At least one inspection hole must be accessible.
The damper must be installed so that the damper blade (in closed position) is situated in the fire separating
structure - marked by the label BUILD-IN EDGE on the damper body. If such solution is not possible, the
piping between the fire separating structure and the damper blade must be protected according to the
certified installation method, see Section 6.
During the installation and plastering process, the control mechanism must be protected (covered) against
damage and pollution. The damper body should not be deformed during bricking in. Once the damper is built
in, the damper blade should not grind on the damper body during opening or closing.
The distance between the fire damper and the structure (wall, ceiling) must be 75 mm at the minimum. If two
or more dampers are to be installed in one fire separating structure, the distance between adjacent dampers
must be 200 mm at the minimum, according to EN 1366-2 paragraph 13.5. For admissible exceptions see
Section 6.
