Description: The BKNE230-24 is a separate power supply unit for BE(G)24-ST smoke extraction damper actuators. It also serves as a communications interface between the actuators and the BKSE24-6 control and monitoring unit.

Communication / Command memory: The 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 factory setting is Close damper command stored in the memory).

Monitoring : 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. It also monitors the actuator current (actuator connected?) and the power supply.

Signalling : The power supply unit incorporates two LEDs to signal its functional status.

Installation and connection : 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.

Note: 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.

Safety function: The safety function is guaranteed within the temperature range shown in the diagram below which is based on standard ÖNORM H 6029 and DIN 18232.
