System L Komb. Signal groß (SBB)
Signal-ID: 205 (hex: 0xCD)
Using this signal configuration, the following signals can for example be operated:
- Stop FB1 FB2 FB3 FB5 Warning
- Stop FB1 FB2 FB3 FB5 Warning FB2*
- Stop FB1 FB2 FB3 Warning FB1* FB2* FB3*
Combined signals can present both distant signal aspects and main signal aspects,
and are suitable for use in short block sections. The wide variety of equipment
variants with different lamps are hard to completely reproduce in models.
In spite of this, the Z21 signal DECODER attempts to depict the most important
combined signals. Through clever wiring, a high number of usage possibilities are
made available.

The white additional board with a black border and black dot marks these signals as main signals which can indicate stop. This even allows differentiation even in case of distant signal faults.
In case of a switched-off signal with this additional board, the engine driver must acknowledge the signal aspect stop.
In case of a switched off combined signal without this additional board, on the other hand, the engine driver has to acknowledge the distant signal aspect warning.
