Fire dampers are shutters in ventilation duct systems that preventing spreading the fire and combustion gases from one fire
compartment to the other one by shutting of closing the air duct in the positions of fire separating constructions. Dampers blade
closes automatically air duct using a shutting spring or an return spring of its actuating mechanism in case of fire. The return spring
of the actuator is started when the thermal fuse is activated. In the case of thermos electrical fuse the activation (closing)
procedure starts, when a reset button on fuse is pushed or when a power supply of the actuating mechanism is stopped. In case
of mechanical control with thermal fuse, the return spring is activated after the moment, when thermal fuse is melted. The
damper´s blade is sealed with a silicon gasket/packing preventing smoke penetration after closing the blade. At the same time,
the damper´s blade will be tighten by intumescent tape, which will be expanding in the case of fire. Dampers have no inspection
door. For inspection of the damper, there is an inspection hole for camera. For others service works there must by installed
inspection door externally on the duct, next to the fire damper. The damper is equipped with additional collar, around the position
of the blade. On the collar, there are positioned several metallic plates (fixtures for easy installation on the wall or ceiling construction.

The damper can be equipped with electric actuating mechanism. There are several actuators: BELIMO BFL, BFN230-T (version .40)
or BFL, BFN24-T (version .50). After connection to the power supply AC/DC 24V or AC230V, the actuating mechanism displaces the
damper blade into operation position "OPEN". At the same time is pre-stretched back spring inside the actuator. When the actuator is
under voltage (on power supply), the damper´s blade is in the position "OPEN". The back spring is pre-stretched. Time needed for full
opening of the damper blade from the position "CLOSED" to the position "OPEN" is maximum 140s (for type BF) or 60s (for type BFL,
BFN). If the power supply of the actuator is cut off (due to disconnection of power supply, or pressing the reset button on the
thermo-electrical starting mechanism BAT (thermal fuse), the back spring displaces the damper´s blade into the safety position
"CLOSED". The time needed for displacing of the blade from the position "OPEN" to the position "CLOSE" takes maximal 20s. In the
case that the power supply is restored again (the blade can be in arbitrary position), the actuator starts re-displacing the damper´s
blade position into the emergency position "OPEN". The thermos-electrical mechanism BAT, which contains two thermal fuses Tf1
and Tf2, is a part of actuator. These fuses are activated when temperature +72°C has been exceeded. The fuse Tf1 measures the
temperature in the outside of the damper and Tf2 measure the temperature inside the air duct. Both fuses, they are in serial
connection. It means in fact, that when one of them is activated, the power supply of the actuator is cut-off and the actuator displaces
the blade in safety position "CLOSED". The signalization of damper position "OPEN" or "CLOSED" is provided by two limit switches,
which are built-in inside the actuator. The thermal fuse BAT can be also installed separately, into the spiral air duct, outside of the fire
damper (order code for this option is .4V or .5V - see the product code).

This is design with the communication and supply device BKN230-24 and the actuator BFL(or BFN)24-T-ST. It simplifies electrical
wiring and interconnection of fire damper. This design facilitates checking of the damper on site and enables central control and check
of fire damper during by a simple "2-wire" wiring with superordinate control unit. BKN230-24 is working as a decentralized network
device for supplying of the actuator BFL(BFN)24-T-ST on one hand and on the other hand it transmits the signal information about the
fire damper position and failure. Control command SWITCH-ON and SWITCH-OFF from superordinate system controls via the same
wiring to the actuating mechanism. To allow more simple connection, the actuator BFL(BFN)24-T-ST is equipped with two connecting
plugs (one with three jacks and one plug with six jacks). They are inserted directly to BKN230-24. BKN230-24 is supplied with a
conductor and EURO-plug for connecting to the 230V mains. Two wire cable from superordinate system is connected to BKN230-24
by means of clamps 6 and 7 in BKN. If the drive is supposed to be controlled without any signal from the superordinate, it can be
switch-on by means of a bridge between clamps 3 and 4 in BKN. A green LED diode on BKN230-24 is lighting in case the voltage 24V
is present in the drive. If the TEST button on BAT 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". It means damper blade goes in position "CLOSED".
Communication and supply device BKN230-24 has to be placed near the damper (BKN isn´t mounted on damper body). It is necessary
for easy connection of actuator equipped by BKN230-24 device.

BKS24-9A communication and control device is used for group control and checks of 1 to 9 fire dampers with the actuator BFL
(BFN)24-T-ST in connection with the supply and communication device BKN230-24. Signalization of the damper blade position
is individual for each damper (9 LED diodes), but the dampers can be controlled and tested only as a group. BKS24-9A is intended
for use in superordinate control system, which can display operation mode and failure reports of the connected fire dampers.
BKS24-9A receives signals from BKN230-24 through two wire cable. Proper damper operation is indicated by two light LED diodes:
Control LED "OPEN" = damper blade in emergency position OPEN
Control LED "CLOSE" = damper blade in safety position CLOSED
If the damper does not reach the required position within the preset time, the appropriate on-board FAULT LED flashes and, at
the same time, the fault contact K1 is activated (K1 is group alarm for all 9 dampers). This contact is overridden as soon the
defective damper reaches the required position. The on-board FAULT LED remains on, until the fault is reset. Auxiliary contact
K2 is provided for signaling the positions of dampers to a supreme communication controlling system. The function of the auxiliary
contact can be programmed via terminal 14 according the next table.
The BKS24-9A unit can be clipped directly onto a 35mm DIN mounting rail and external wiring is connected by two 9-pin terminal
connectors.
Functional testing can be performed by pressing the TEST pushbutton. While this button is held depressed, the dampers run to
the safe position. Any malfunctions are indicated by the internal FAULT LED´s.

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-ducting 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 be able to provide inspection, inside of the fire damper is the damper with camera inspection hole standardly
equipped. For other service works, the external access door (inspection hole) must be installed on the air duct, next to the fire
damper.
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 13.6.
The control mechanism has to be protected (covered) against damage and pollution during installation process. 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.
