Smoke Control Damper
2.4. Communication and control device
BKSE 24-6 indicates operating condition and faults of flue dampers. These conditions can be signalled or transmitted to the
higher-level control system via the auxiliary built-in contacts. Signals from individual BKNE 230-24 are evaluated separately.
All BKNE 230-24 are controlled simultaneously. A maximum of 6 BKNE 230-24 can be connected to the BKSE 24-6.
Damper control is ensured with a simple 2-wire line. The damper's correct function is indicated by two LEDs. The operating
status of the entire control system and any errors are indicated by these LEDs and the corresponding error LED.
Mounting and connection of BKSE 24-6 can be done on a 35mm DIN rail. It's connected using two 9-pin terminal blocks
(plug connectors).
