3.3.4 Line separator
All C-NET devices are equipped with a line separator.
The C-NET device is equipped with electronic switches which isolate the defective
part in case of a short-circuit on the C-NET detector line. The rest of the detector
line remains serviceable. On a loop line all C-NET devices remain fully functional
after a simple error.
3.3.5 Internal alarm indicator in the case of ES <10
The point detectors have an internal alarm indicator. The internal alarm indicator
shows the point detector's operating status:
Operating condition
Flashing mode of the IAI
Normal IAI off
Alarm IAI lights up every second
Test mode IAI off
Alarm in test mode IAI lights up every second
The flashing behavior of the point detectors in the case of ES ≥10 is described in
the 'Extended flashing behavior of alarm indicators in the case of ES ≥10 [➙ 22]'
chapter.
Information about the product version of your device can be found in the 'Product
version ES [➙ 16]' chapter.
