BKS24-9A communication and control device is used for group control and checks of 1 to 9 fire dampers with the actuator BFL
(BFN)24-T-ST in connection with the supply and communication device BKN230-24. Signalization of the damper blade position
is individual for each damper (9 LED diodes), but the dampers can be controlled and tested only as a group. BKS24-9A is intended
for use in superordinate control system, which can display operation mode and failure reports of the connected fire dampers.
BKS24-9A receives signals from BKN230-24 through two wire cable. Proper damper operation is indicated by two light LED diodes:

Control LED "OPEN" = damper blade in emergency position OPEN

Control LED "CLOSE" = damper blade in safety position CLOSED

If the damper does not reach the required position within the preset time, the appropriate on-board FAULT LED flashes and, at
the same time, the fault contact K1 is activated (K1 is group alarm for all 9 dampers). This contact is overridden as soon the
defective damper reaches the required position. The on-board FAULT LED remains on, until the fault is reset. Auxiliary contact
K2 is provided for signaling the positions of dampers to a supreme communication controlling system. The function of the auxiliary
contact can be programmed via terminal 14 according the next table.

The BKS24-9A unit can be clipped directly onto a 35mm DIN mounting rail and external wiring is connected by two 9-pin terminal
connectors.
Functional testing can be performed by pressing the TEST pushbutton. While this button is held depressed, the dampers run to
the safe position. Any malfunctions are indicated by the internal FAULT LED´s.
