Variant B:
1. Connect the positive pole of the external alarm indicator to the positive pole for
the alarm indicator on the detector.
2. Leave the negative pole for the alarm indicator on the detector unoccupied.
3. Connect the negative pole of the external alarm indicator with the negative
terminal on the input side of the collective line on the detector via an auxiliary
terminal DBZ1190-xx.
4. Connect the shielding of the collective line with the shielding of the connection
cable to the external alarm indicator via an auxiliary terminal DBZ1190-xx.
On an MS8 detector line an external alarm indicator may be connected to only one
detector.
