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. In the case of FDMS the fire dampers
blade closes automatically air duct using a shutting spring or an return spring of its actuating mechanism in case of fire. In the case of
FDMS-VAV the fire damper has an additional function of the variable air flow controller. The return spring of the actuator is started when
the thermal fuse is activated or the actuator is without power supply. In the case of thermal 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 FDMS
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, BFN 230-T (version .40)
or BFL, BFN 24-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 60s. 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 (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.

The damper is equipped with electric actuating mechanism. There are several actuators depending on the damper size: GRUNER
340CTA-024D-XX-S2-V/8F12/ST06/BP8. To ensure the VAV function there is an Gruner universal actuator controller GUAC-DM3
for air flow control and GUAC-PM3 for pressure control. After connection to the power supply AC/DC 24V, the actuating
mechanism displaces the damper blade into operation position given by the required air volume flow. 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 given by the required air volume flow. The back spring is pre-stretched. 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 given by the required air volume flow.
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
fire damper has a part with controller consists of the body of the controller with a control blade and pressure probes for determining
the through-flow of air. A controller is affixed to the body for controlling the control blade, which is in this case the blade of the fire
damper.

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.
