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.
The damper blade automatically closes the air duct using a shutting spring or an actuating mechanism
of back spring. The shutting spring is activated by pressing the start button or by the impulse from the
thermal fuse. The back spring of the actuating mechanism is started when the thermoelectric starting
mechanism BAT is activated, when the reset button on BAT is pressed or when the power supply to
the actuating mechanism is stopped.
After closing the blade, the damper is sealed with a silicon packing against smoke penetration. The
damper can be delivered with a seal without silicone at the customer's wish. At the same time, the
damper blade is embedded in a material which enlarges its volume due to increasing temperature and
hermetically seals the air duct.
The dampers have one inspection hole, as the shutting device and the inspection hole can be set to
the most advantageous position with respect to operation and handling of the control device by turning
the damper a little in case of the spiro model of the dampers.
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).
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.

Design with actuating mechanism
The dampers are equipped with Belimo actuating mechanisms with back spring and thermoelectric
actuating device, of range BF (hereinafter referred to only as the "actuating mechanism"). After being
connected to power supply AC/DC 24V or AC 230V, respectively, the actuating mechanism moves
the damper blade to "OPEN" operation position and at the same time pre-stretches its back spring.
While the actuating mechanism is under voltage, the damper blade is in the "OPEN" position and the
back spring is pre-stretched. The time needed for full opening of the damper blade from "CLOSED"
position to "OPEN" position is 120 seconds at the maximum. if the power supply to the actuating
mechanism is cut off (due to loss of power supply or by pressing the reset button on the BAT
thermoelectric starting mechanism), the back spring will move the damper blade to "CLOSED" failure
position. The time of moving the blade from "OPEN" position to "CLOSED" position takes 20
seconds at the maximum. If the power supply is restored (the blade can be in any position), the
actuating mechanism starts to move the damper blade to "OPEN" position again.
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" and "CLOSE" is provided by two limit switches.

Design with the communication and supply device BKN 230-24 and the actuating mechanism
BF 24-TN-ST. 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 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 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".

the BF 24-TN-ST for communication with control systems using the Modbus RTU or BACnet MS
/ TP protocol. The wiring of the line is to be carried out in accordance with applicable RS485
regulations. Parameterization of the communication is done using DIL switches. The BKN
230-24-MOD can be installed separately, without a connection to a master control system, in
which case the connection bridge between the terminals 1 and 4 must be installed. For more
information, see the Belimo catalog.

BKS 24-1B communication and control device is used for control and checks of fire dampers with
BF 24-TN-ST actuating mechanism in conjunction with the BKN 230-24 supply and
communication device. BKS 24-1B receives information about the situation of the fire damper
through the BKN 230-24 supply and communication device and issues controlling commands.
The device is intended for building in into the distribution board. Light diodes on the front side of
the device signalise the operating situations of the damper and breakdowns of the whole system.
Potentialless auxiliary contacts enable connection to the master control system (signaling of the
damper position, failure reports, release of the ventilators etc.).
While a flashing green LED pilot light signalises damper blade motion towards the given position,
the same pilot light reports reaching the required position when shining constantly. If the flap
blade, with respect to the given time, does not reach the required position, then a red LED pilot
light starts to flash and at the same time, the failure contact is active. Once the damper blade
reaches the given position, this contact is deactivated. The LED pilot light keeps flashing unless
the failure is unblocked by means of the RESET button. Except for reporting failures, other three
auxiliary contacts are available. Contacts showing operating and failure position of the damper
are active when the damper is in the given position. Function check can be done by pressing and
holding the button "RESET/TEST" for longer time. While holding the button, the damper blade
moves in the direction of the failure position. Fault function is indicated by the LED pilot light.
BKS 24-1B can be connected by means of ZSO-11 11 pole connector for DIN 35 mm panel.

BKS 24-9A communication and control device is used for group control and checks of 1 to 9 fire
dampers with the actuating mechanism BF 24-TN-ST in connection with the supply and
communication device BKN 230-24. Signalisation of the damper position is individual; the
damper can be controlled and tested only as a group. BKS 24-9A is intended for use in the
distribution board and displays the operation situations and failure reports of the connected fire
dampers. It is possible to signalise functions such as the damper position and failure reports or to
transmit them further to the system by means of integrated auxiliary switches. BKS 24-9A
receives signals from BKN 230-24 through the two-conductor wiring and issues control
commands. Proper damper operation is indicated by two light LED diodes:
Control ON = position OPERATION
Control OFF = position FAILURE
If the fire damper do not reach the given position in time tolerable for displacing, the appropriate
light diode FAILURE starts to flash and K1 contact is opened (current failure). In case that the
faulty damper finally reaches its given position, K1 is closed and the failure report light shines (the
failure is saved in memory). K2 - the auxiliary contact - is used for signaling of the flap position to
the master device. Function of this auxiliary contact can be programmed through the terminal
14 according to the Tab. 3.2.1.

The 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
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.
