Connection
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.).
