Line separator

All FDnet/C-NET devices are equipped with a line separator.
The FDnet/C-NET device is equipped with electronic switches which isolate the
defective part in case of a short-circuit on the detector line. The rest of the detector
line remains serviceable. On a loop line all FDnet/C-NET devices remain fully
functional after a simple error.

Danger levels

The detector can transmit the following danger levels to the control panel:
Danger level Meaning
0 No danger
1 Check situation
1
2 Warning
1
3 Alarm
The evaluation of the danger level and the decisions to be taken (e.g. activation of
remote transmission) are configured in the control panel.
Danger levels 1 and 2 are only transmitted to FDnet/C-NET detector lines. On a
1
collective detector line, only danger levels 0 and 3 can be transmitted to the control
panel.
