■
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.
