1. Description
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.

1.2 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 designed for macroclimatic areas with mild climate according to EN 60 721-3-3.
Dampers are suitable for systems without abrasive, chemical and adhesive particles.
Temperature in the place of installation is permitted to range from –30 °C to +50 °C.
If electric elements are installed on the damper, the temperature range is narrowed according to the temperature
range of the electric elements used (see chapter 2 ”Design”).
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).
ATTENTION!
Mechanisms are produced in four designs M1 to M4,
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 mechanism - Tab. 3. 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
Design .80
Design .01 with mechanical control can be complemented with a terminal switches signaling of the damper
blade position ”CLOSED” and ”OPEN”. Limit switches are connected via damper casing, cables are connected
directly to limit switches.

2.2 Design with actuating mechanism
Design .40, .50
The damper are equipped by Belimo actuators with spring return and thermoelectric activation device of BFL,
BFN or BF depending on the damper size (furher mentioned as „actuators“). 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
Fire dampers are suitable for installation in arbitrary position in vertical and horizontal passages of fire separating
constructions. Damper assembly procedures must be done so as all load transfer from the fire separating
constructions to the damper body is absolutely excluded. Back-to-back air-conditioning piping must be hung or
supported so as all load transfer from the back-to-back piping to the damper is absolutely excluded. Installation
gap must be filled by approved material perfectly in all the installation space volume (installation gap).
To provide needed access space to the control device, all other objects must be situated at least 350 mm from
the control parts of the damper. Inspection hole must be accessible.
Damper blade has to be inside of construction (labelled with BUILD IN EDGE on the damper body) after
installation. The fire damper can also be installed 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 firefighting insulation.
The distance between the fire damper and the construction (wall, ceiling) must be minimum 75 mm. In case that
two or more dampers are supposed to be installed in one fire separating construction, the distance between
the adjacent dampers must be at least 200 mm according to EN 1366-2 paragraph 13.5.
Exceptions are given in chapter 5.

Built in edge
Fig. 15 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.

The control mechanism has to be protected (covered) against damage and pollution during installation process.
All fire dampers has to be closed during installation process. The damper body should not be deformed in
the course of bricking in. Once the damper is built in, its blade should not grind on the damper body during
opening or closing.
4.1 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 for dampers
with dimension A ≥ 800 mm.
Important! For lower fire resistance than EI 90 the reinforcement VRM-B is not necessary!
