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 or an electromagnetic one. The
back spring of the actuating mechanism is started when the thermoelectrical starting mechanism
BAE 72B-S is activated, when a reset button on BAE 72B-S 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.
Square dampers have two inspection holes. Round dampers have one inspection hole, since the
shutting device and the inspection hole can be set into the most advantageous position (with
respect to the operation and manipulation with the control device).
1.3. 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) Dampers could be displaced into position “CLOSED” only in case that ventilator, or Air
Handling Unit is switched off. The goal is the securing of proper closing and safe
function of Fire Damper in case of Fire.
c) 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.

Design .01 or .11 with mechanical control can be complemented with initiation by means of an
electromagnet (solenoid). The voltage of the electromagnet (solenoid) can be AC 230V, AC/DC
24V. By voltage AC 230 V is damper equipped by electromagnet EM230. By voltage AC/DC 24
V is damper equipped by electromagnet EM230 with pre-pulse switch SIEM24. SEIM24 activates
the electromagnet after capacitor charge witch is placed inside of SIEM24. It takes about 10 sec.
Charging time depends on the current supply. For reliable operation is necessary connect to
electromagnet or pre-pulse switch appropriate supply for 20 to 30 sec. After activation of
electromagnet is released initiation lever and damper is closed. After activation is initiation lever
released. If is damper set up in position "OPEN" is necessary unlock initiation lever by pulling of
electromagnet core.

Design .40, .50
FDMB is always equipped by electric actuating mechanism BLF(BF) 230-T or BLF(BF) 24-T
(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
140 sec. If the actuating power supply is cut off (due to loss of supply voltage, activation of
thermoelectrical actuating mechanism or pushing the reset button on the thermoelectrical starting
mechanism BAE 72B-S), 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 16 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 BAE 72B-S, which contains two thermal fuses Tf1 and
Tf2/Tf3, 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/Tf3 when the temperature inside the air-conditioning piping has been exceeded). After the
thermal fuse Tf1 or Tf2/Tf3 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".

2.3. Design with the communication and supply device
Design .60
Design with the communication and supply device BKN 230-24 and the actuating mechanism
BF 24-T-ST (BLF 24-T-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-T-ST (BLF 24-T-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-T-ST (BLF 24-T-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 BAE 72-S 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".

3. Communication an control evices
3.1. BKS 24-1B communication and control device is used for control and checks of fire dampers with
the BF 24-T-ST (BLF 24-T-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.

3.2. 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-T-ST (BLF 24-T-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.
