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. Closing spring is released either by pushing of the button or by thermal fuse.
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.

Working conditions
Right damper function is secured under the following conditions:
a) Maximum air circulation speed: 12 m/s
Maximum pressure difference: 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.

Design with mechanical control
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).
Mechanisms are produced in four designs to ,
difference 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 - It is not
recommended to use different 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 limit switch signalling of the
damper blade position "CLOSED". Cable is connected directly to limit switch.

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 off (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 off 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.

Design .41 or .51 with actuating mechanism can be complemented with smoke detector ORS 142
K. The voltage can be AC 230 V or 24 V DC. Design with voltage AC 230 V is equpped with
Communication and supply device BKN 230-24-MOD and with actuating mechanism BF 24-TN
(BFL 24-T, BFN 24-T).
The smoke detector is activated when smoke spreads in air duct system. Deactivation of smoke
detector is provided by interruption of supply voltage for min. 2s.
Signalisation of damper blade position "OPEN" a "CLOSE" is provided by two limit switches.
The smoke detector sensor is not part of the fire damper in the case of dampers from A<160 or

Design with the communication and supply device BKN 230-24 and the actuating mechanism
BF 24-TN-ST (BFL 24-T, BFN 24-T). It simplifies electrical wiring and interconnection of fire flap
valves. It facilitates on site check and enables central control and checks of fire damper by means
of a simple 2-conductor wiring.
BKN 230-24 functions as a decentralized network device for supplying the actuating mechanism
BF 24-TN-ST (BFL 24-T, BFN 24-T) with a spring back drive on one hand and on the other hand
it transmits the signal informing about the flap valve position OPERATION and FAILURE through
2-conductor wiring to the central. Control command SWITCHED ON - SWITCHED OFF from the
central through BKN 230-24 goes through the same wiring to the actuating mechanism.
To simplify the connection, the actuating mechanism BF 24-TN-ST (BFL 24-T, BFN 24-T) is
equipped with connecting plugs that are inserted directly to BKN 230-24. BKN 230-24 is supplied
with a conductor and an EURO plug to be connected to the 230V mains. 2- conductor wiring is
connected to BKN 230-24 by means of terminals 6 and 7. If the drive is supposed to be controlled
without any signal from the central, it can be switched on by means of a bridge between the
terminals 3 and 4. A green LED pilot light on BKN 230-24 is on when voltage is present in the
drive (AC 24V).
If the button on BAT is switched on or if the power supply (e.g. by a signal from ELECTRICAL
FIRE SIGNALISATION ) is disconnected, the damper position will be "FAILURE".
