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 or an electromagnetic 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 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 -30°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).
Design .11
Design .01 with mechanical control can be complemented with a limit switch signalling of the damper blade

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.

Dampers can be supplied on the customer´s demands in all subdimension of the above mentioned range.
Flanges of dampers are 30 mm wide with oval hole (Fig. 15).
These values have to respected when projecting related air-conditioning ducts

4. Placement and Assembly
4.1
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.
Fig. 16 The distance between the fire damper and the construction
"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 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-Q.
Important: For lower fire resistance than EI90 the reinforcement VRM-Q is not necessary!!!
