Fire dampers are shutters in duct systems 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 air
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 back spring of the actuating mechanism is started when the thermoelectrical
starting mechanism BAT72B-S is activated, when a reset button on BAT72B-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.
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
Exact damper function is provided under the following conditions:
a) Maximum air circulation speed: 12 m.s
Maximum pressure difference: 1500 Pa
b) The air circulation in the whole damper section must be secured as steady on whole
surface.

4
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 actuating mechanism
Actuating mechanism
BAT
FDMC is always equipped by electric actuating mechanism BFL (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 60 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
Design with the communication and supply device BKN 230-24 and the actuating mechanism
BFL 24-T-ST. It simplifies electrical wiring and interconnection of fire damper. 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
BFL 24-T-ST with a spring back drive on one hand and on the other hand it transmits the signal
information about the fire damper 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 BFL 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 BAT72B-S is switched on or if
the power supply (e.g. by a signal from ELECTRICAL FIRE SIGNALISATION) is disconnected,
the fire damper position will be "FAILURE".
Communication and supply device BKN 230-24 has to be placed near the damper. It is necessary
for easy connection of actuating system equipped by BKN 230-24 device.

BKS 24-9A communication and control device is used for group control and checks of 1 to 9 fire
dampers with the actuating mechanism BFL 24-T-ST in connection with the supply and
communication device BKN 230-24. Signalisation of the damper position is individual; the
dampers 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 dampers 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 lights up shines
(the failure is saved in memory).
K2 - the auxiliary contact - is used for signalisation of the flap position to the master device. Function
of this auxiliary contact can be programmed through the terminal 14 according to the Tab. 3.1.1.

BKS 24-1B communication and control device is used for control and checks of fire dampers with the
BFL 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 indicates the
operating situations of the damper and breakdowns of the whole system. Nonpotential auxiliary
contacts enable connection to the master control system (indication of the damper position, failure
reports, release of the ventilators etc.).

While a flashing green LED pilot light signalises flap blade motion towards the given position, the
same pilot light reports reaching the required position when shining constantly. If the damper, 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.

Fire dampers are suitable for installation in arbitrary position in vertical and horizontal passages
of fire separating constructions. Damper assembly procedures must be done so as all load
transfer from the fire separating constructions to the damper body is absolutely excluded.
Back-to-back air-conditioning piping must be hung or supported so as all load transfer from the
back-to-back piping to the damper is absolutely excluded. Installation gap must be filled by
approved material perfectly in all the installation space volume (installation gap).
To provide needed access space to the control device, all other objects must be situated at least
350 mm from the control parts of the damper. Inspection hole must be accessible.
Damper blade has to be inside of construction (labelled with BUILD IN EDGE on the damper
body) after installation. The fire damper can also be installed outside the wall construction. Duct
and the damper part between the wall construction and the damper blade (labelled with BUILD
IN EDGE on the protective covering) must be protected with firefighting insulation (see fig. 12).
The distance between the fire damper and the construction (wall, ceiling) must be minimal in
range from 10 to 50 mm. In case that two or more dampers are supposed to be installed in one
fire separating construction, the distance between the adjacent dampers must be at least 50 mm.
Exceptions are given in chapter 6.
