Fig. 7 Communication and Control Device BKS 24-9A
3.2. BKS 24-1B communication and control device is used for control and checks of fire dampers with
the BFL 24-T-ST actuating mechanism in conjunction with the BKN 230-24 supply and
communication device. BKS 24-1B receives information about the situation of the fire damper
through the 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 indicates the operating situations of the damper and breakdowns of the whole system.
Nonpotential auxiliary contacts enable connection to the master control system (indication of the
damper position, failure reports, release of the ventilators etc.).
