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.
rectangular 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).

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 - 30°C to + 50°C.

Design with mechanical control with a thermal protective fuse which actuates the shutting device
within 120 seconds at latest 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 limit switch signaling of the
damper blade position "CLOSED".

Design .01 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.

FDMB is always equipped by electric actuating mechanism BFL, BFN, BF 230-T or BFL, BFN,
BF 230-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, 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 with the communication and supply device BKN 230-24 and the actuating mechanism
BF 24-T-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-T-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-T-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 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".

BKS 24-1B communication and control device is used for control and checks of fire dampers with
the BF 24-T-ST (BFL 24-T-ST, BFN 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.

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 (BFL 24-T-ST, BFN 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.
