Description
Working conditions
■Exact damper function is provided under the following conditions:
■maximum air velocity 12 m/s
■maximum pressure difference 1200 Pa
■the air circulation in the whole damper section must be secured steady over the entire surface.
■Dampers can be installed in position with horizontal or vertical blade axis.
■Dampers can be installed in position with actuating mechanism on top or on the side of the damper.
■Dampers are suitable for systems without abrasive, chemical and adhesive particles.
■Dampers are designed for macroclimatic areas with mild climate according to EN IEC 60 721-3-3 ed.2., class 3K22.
(Environment 3K22 is typically protected place with regulated temperature)
■Temperature in the place of installation is permitted to range from -30°C to +50°C.
Fire dampers are shutters in ducts of air-conditioning devices
that prevent the spread of 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.
Damper blade automatically closes air duct using a closing
spring or a spring return actuator. The closing spring is
actuated by pressing a button on the manual control or by
melting a thermal fuse.
The return spring of the actuator is actuated when a
thermoelectric activation device BAT is activated, when a test
button on BAT is pressed or when power supply of the
actuator is interrupted.
After closing the blade, the damper is sealed with silicon
against smoke penetration. On request by customer, the
damper can be supplied silicon-free. In the closed position,
the damper is also sealed with material which increases its
volume due to increasing temperature and air proofs the air
duct.
Dampers have two inspection openings.

Design with spring return actuator
■The fire dampers are equipped with Belimo spring return
actuators with thermoelectric activation device BAT. The
spring return actuator types are BFL, BFN or BF depending
on the damper size. (Further mentioned as „actuator“).
■After being connected to power supply 230V or AC/DC
24V, the actuator rotates the damper blade to the
operating position "OPEN" and at the same time pre-
stretches its return spring.
■When the actuator is power supplied, the damper blade is
in the position "OPEN" and the return spring is pre-
stretched.
■Time needed for full opening of the damper blade from
the position "CLOSED" to the position "OPEN" is maximum
120 sec. If the actuator power supply is interrupted (due
to loss of supply voltage, or pressing a test button on the
thermoelectric activation device BAT), the actuator
rotates the damper blade to the breakdown position
"CLOSED".
■The time of closing the damper 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 actuator starts to rotate the
damper blade back to the position "OPEN".
■A thermoelectric activation device BAT, which contains
two thermal fuses Tf1 and Tf2, is an integral part of the
actuator.
■These fuses are activated when temperature +72°C has
been reached (the fuse Tf1 due to temperature outside
the duct and the fuse Tf2 due to temperature inside the
duct). The thermoelectric activation device can also be
equipped with a Tf2 thermal fuse type ZBAT 95/120/140
(must be specified in the order). In this case, the activation
temperature inside the duct is +95°C, +120°C or +140°C
(depending on the type).
■After the thermal fuse Tf1 or Tf2 has been activated, the
power supply is permanently and irreversibly interrupted
and the actuator, by means of the pre-stretched spring,
rotates the damper blade into the breakdown position
"CLOSED".
■Signalisation of damper blade position "OPEN" and
"CLOSE" is provided by two microswitches.

Optical smoke detector ORS 142 K with the socket 143A
■The smoke detector ORS 142 K is used for early smoke detection
in rooms or inside the ventilation system.
■The sensor operates on the light scatter principle. Inside the
scanning chamber is a light source and a light sensor, in the
normal state the light from the source does not fall on the
senzor. Only when smoke enters the scanning chamber the light
is scattered and falls on the senzor.
■The smoke detector can be connected directly to the actuator
(design .41 and .51) which, in case of smoke detection, passes to
the safety position, or to the BKN communication and supply
device (design .61, .63).
■By early detection of smoke, it can be effectively prevented from
spreading of smoke through the ventilation system. In addition
to smoke detection, the sensor can distinguish and signal slight
and heavy contamination, e.g. the presence of large amounts of
dust.
■The ORS 142 K smoke detector has an alarm memory, i.e. if the
alarm is triggered, the safety relay opens and stays in this state
even if the smoke disappears from the scanning chamber. The
sensor remains in the alarm state until the power supply is
briefly reset.
■On the pin 3, an external device can be connected via RS-Bus
communication to report the status of the sensor.
■Pin 6 has no connection to the detector and is designed as a
load-bearing structure in the base.

■BKS 24-1B communication and control device is used for control
and checks of fire dampers with the BF 24-TN-ST (BFL 24-T-ST, BFN
24-T-ST) actuator in conjunction with the BKN 230-24 supply and
communication device.
■BKS 24-1B receives information about the situation of the fire
damper through 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 damper 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 rotates 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 actuator BF
24-TN-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 damper
blade position to the master device.
■Function of this auxiliary contact can be programmed through the
terminal 14.
■Function check can be done in the position OPERATION by means
of pressing the TEST button.
■While the test button is pressed, damper blade is rotating into the
position FAILURE.
■Fault function is indicated by a report "FAILURE".
■Assembly and connection BKS 24-9A can be made by DIN 35 mm
panel. It is connected by two 9-pole plug-in connectors.
