Design with the communication and supply device
Design with the communication and supply device BKNE230-24 and the actuating mechanism
BLE24(BE24-12)-ST.
BKNE230-24 functions as a decentralized network device for supplying the actuating mechanism
BLE24(BE24-12)-ST on one hand and on the other hand it transmits signals from communication
and control device BKSE24-6.
It simplifies electrical wiring and interconnection of dampers. It facilitates on site check and
enables central control and checks of fire damper by means of a simple 2-conductor wiring.
BKNE230-24 signals the damper position „OPEN“/„CLOSED“ (from switches on the actuator)
and any fault alarms to the BKSE24-6 unit. It also receives positioning commands from the
control unit and triggers the actuator to the required position. The last control command is
retained troughout temporary power failures.
The BKNE230-24 unit monitors the positions of the switches on the actuator, its running time and
the exchange of data with the control and monitoring unit BKSE24-6. It also monitors the actuator
current and the power supply. In order to make installation as simple as possible the smoke
extraction damper actuators ...-ST are fitted with plug connectors that can be inserted directly into
the BKNE230-24 unit.
The 2-wire conductor must be connected to screw terminals 6 and 7. It is recommended that a
fire alarm signal cable suitable for the application be used for the 2-wire conductor. It is essential
to ensure the correct polarity. More information in catalogue Belimo.
