3.3.3 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 FDnet/C-NET detector line. The rest
of the detector line remains serviceable. On a loop line, all FDnet/C-NET devices
remain fully functional after a single short-circuit.

in test mode, alarms from the manual call points are not forwarded by the control
panel.
