What are latency, confidence and alarm inhibition?

These parameters provide an improved alarm management performance not only based on impulse.

Parametri Sensore

You can set the following parameters in the menubar:

  • Latency: latency time of the alarm in seconds; it is the minimum duration of the alarm condition; the alarm is not notified if the alarm condition does not persists for at least the confidence percentage of the latency time.
  • Confidence: the minimum percentage of the latency time in which the alarm condition must be detected to raise an alarm. Therefore, the alarm is not generated if the alarm condition does not persist for at least the confidence percentage of the latency time. The higher is the confidence, the lower is the probability to raise false alarms; on the other hand, it can increase the false negative probability and viceversa.
  • Inhibition: inhibition time expressed in seconds, representing the minimum timespan between two consecutive alarms on the same sensor; basically, an alarm generated on a sensor will be ignored if the inhibition time is not over yet.
