Use of shielded cables
The detector line shielding must be connected through in the detector base with
auxiliary terminals DBZ1190-xx.
There are two ways of connecting external alarm indicators:

Variant A
1. Connect the positive pole of the external alarm indicator to the positive pole for
the external alarm indicator on the detector.
2. Connect the negative pole of the external alarm indicator to the negative pole
for the external alarm indicator on the detector.
3. Connect the shielding of the connection cable between the external alarm
indicator and detector on the detector side to the positive pole for the external
alarm indicator via an auxiliary terminal DBZ1190-xx.
Variant B
1. Connect the positive pole of the external alarm indicator to the positive pole for
the external alarm indicator on the detector.
2. Leave the negative pole for the external alarm indicator on the detector
unoccupied.
3. Connect the negative pole of the external alarm indicator with the negative pole
on the input side of the detector line on the detector via an auxiliary terminal
DBZ1190-xx.
4. Connect the shielding of the detector line with the shielding of the connection
cable to the external alarm indicator via an auxiliary terminal DBZ1190-xx.
