(see Chapter: STOP Button and Configuration).
IMPORTANT: When using occupied detectors with a shared connection pole (10808: Input "N",
10787: Input "+"), it is to be ensured that only a single booster output is to be connected to this
shared connection pole, i.e. the connecting of various booster outputs and/or the control centre
with the same shared connection pole at the detector is not permissible. The booster power circuit
is also to remain disconnected at the occupied detector.
