4.2.6.1 Monitoring with Collective Detection Line
Collectively addressed detector zone (detector zone = detector line) with point-type
smoke detectors or Aspirating smoke detectors.
In the case of using a small extinguishing panel e.g. XC10 cross zoning monitoring
has to be applied. If both monitoring zones are in alarm the extinguishing process
starts.

4.2.6.2 Monitoring with Addressable Detection Line
Addressable point detectors or Aspirating smoke detectors are connected directly
to the fire detection loop.
If two detectors in the extinguishing zone are in alarm, the fire detection system
triggers the extinguishing panel e.g. XC10 to start the extinguishing process.
