II. GENERAL INFORMATION
1. Description
1.1.
Fire dampers are shutters in piping 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 piping in the points of fire separating constructions.
1.4.
The damper is sealed with a silicon packing against smoke penetration after closing the blade. At
the same time, the damper blade is bed in a material which enlarges its capacity and air proofs
the air duct.
1.3.
Dampers blade automatically closes air duct using an actuating mechanism back spring. 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.
1.5.
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).
1.6. Exact damper function is provided under the following conditions:
a) Maximum air circulation speed: 12 m.s
-1
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.
1.7. Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3.
1.8. Dampers are suitable for systems without abrasive, chemical and adhesive particles.
1.9. Temperature in the place of installation is permitted to range from - 20°C to + 50°C.
1.11. In this document are used next signs and units.
1.10. If is not noticed other way, all dimensions and weight are in millimeters and kilograms.

2.1.2.
Design with the communication and supply device BKN 230-24 and the actuating mechanism
BLF 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
BLF 24-T-ST with a spring back drive on one hand and on the other hand it transmits the signal
informing 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 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 fire damper position will be "FAILURE".
2.1.3.
Signaling damper blade position "OPEN" and "CLOSED" is secured by two built-in, firmly set
terminal switches.
2.1. Actuating mechanism
2.2. Communication and control devices
2.2.1.
BKS 24-1B communication and control device is used for control and checks of fire flap valves
with the 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.
Nonpotential auxiliary contacts enable connection to the master control system (signalisation 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.
2. Design
2.1.1.
Design with an actuating mechanism BLF 24-T or BLF 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 140s. 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 s. 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 three 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".

Except for reporting failures, other three auxiliary contacts are available. Contacts showing
operatingandfailurepositionoftheflapvalveareactivewhentheflap valveisinthegivenposition.
Function check can be done by pressing and holding the button "RESET/TEST" for longer time.
While holding the button, the flap 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.
2.2.2.
BKS 24-9A communication and control device is used for group control and checks of 1 to 9 fire
dampers with the actuating mechanism BLF 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 light shines (the
failure is saved in memory).
K2-theauxiliarycontact-isusedforsignalisationoftheflappositiontothemasterdevice.Function
of this auxiliary contact can be programmed through the terminal 14 according to the Tab. 2.2.1.

4. Placement and Assembly
4.1.
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.
3.3.
For fire damper the open damper blade overlaps the damper body from dimension 250 by the
“a” value. These values are specified in the Tab. 3.2.1
Value has to be respected when projecting related air-conditioning piping.

4.4.
The control mechanism has to be protected (covered) against damage and pollution during
installation process.
4.5.
All fire dampers has to be closed during installation process. The damper body should not be
deformed in the course of bricking in. Once the damper is built in, its blade should not grind on
the damper body during opening or closing.
4.6. Installation opening dimensions
4.2.
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.
4.3.
The distance between the fire damper and the construction (wall, ceiling) must be minimum
75 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 200 mm according to
EN 1366-2 paragraph 13.5.
