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.

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
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.
