3. Communication and control devices

3.1. BKS 24-9A communication and control device is used for group control and checks of 1 to 9 fire
dampers with the actuating mechanism BFL 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 lights up shines
(the failure is saved in memory).
K2 - the auxiliary contact - is used for signalisation of the flap position to the master device. Function
of this auxiliary contact can be programmed through the terminal 14 according to the Tab. 3.1.1.
