■
BKS 24-1B communication and control device is used for control
and checks of fire dampers with the BF 24-TN-ST (BFL 24-T-ST, BFN
24-T-ST) actuator in conjunction with the BKN 230-24 supply and
communication device.
■
BKS 24-1B receives information about the situation of the fire
damper through 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 signalise the operating
situations of the damper and breakdowns of the whole system.
■
Potentialless auxiliary contacts enable connection to the master
control system (signaling of the damper position, failure reports,
release of the ventilators etc.).
■
While a flashing green LED pilot light signalises damper blade
motion towards the given position, the same pilot light reports
reaching the required position when shining constantly.
■
If the damper blade, with respect to the given time, does not
reach the required position, then a red LED pilot light starts to
flash and at the same time, the failure contact is active.
■
Once the damper blade reaches the given position, this contact is
deactivated.
■
The LED pilot light keeps flashing unless the failure is unblocked
by means of the RESET button.
■
Except for reporting failures, other three auxiliary contacts are
available. Contacts showing operating and failure position of the
damper are active when the damper is in the given position.
Function check can be done by pressing and holding the button
"RESET/TEST" for longer time. While holding the button, the
damper blade rotates in the direction of the failure position. Fault
function is indicated by the LED pilot light.
■
BKS 24-1B can be connected by means of ZSO-11 11 pole
connector for DIN 35 mm panel.
