This is design with the communication and supply device BKN230-24 and the actuator BFL(or BFN)24-T-ST. It simplifies electrical
wiring and interconnection of fire damper. This design facilitates checking of the damper on site and enables central control and check
of fire damper during by a simple "2-wire" wiring with superordinate control unit. BKN230-24 is working as a decentralized network
device for supplying of the actuator BFL(BFN)24-T-ST on one hand and on the other hand it transmits the signal information about the
fire damper position and failure. Control command SWITCH-ON and SWITCH-OFF from superordinate system controls via the same
wiring to the actuating mechanism. To allow more simple connection, the actuator BFL(BFN)24-T-ST is equipped with two connecting
plugs (one with three jacks and one plug with six jacks). They are inserted directly to BKN230-24. BKN230-24 is supplied with a
conductor and EURO-plug for connecting to the 230V mains. Two wire cable from superordinate system is connected to BKN230-24
by means of clamps 6 and 7 in BKN. If the drive is supposed to be controlled without any signal from the superordinate, it can be
switch-on by means of a bridge between clamps 3 and 4 in BKN. A green LED diode on BKN230-24 is lighting in case the voltage 24V
is present in the drive. If the TEST button on BAT is switched-on or if the power supply (e.g. by a signal from ELECTRICAL FIRE
SIGNALISATION) is disconnected, the fire damper position will be "FAILURE". It means damper blade goes in position "CLOSED".
Communication and supply device BKN230-24 has to be placed near the damper (BKN isn´t mounted on damper body). It is necessary
for easy connection of actuator equipped by BKN230-24 device.
