Stale alarms are alarms which are/were on for 24 hours or more and transitioned in the period selected.

The historical view of stale alarms report will show alarms that

  • were on for 24 hours in the selected period (1).
  • transitioned after 24 hours (or more) in the selected period (2,3)
  • were on for longer than 24h but haven't returned to normal within the selected period (4).
  • were on for longer than 24h but haven't started inside the selected period boundaries (5).

This can be visualised like so:

Example 6 is part of standing alarms report and does not contribute to stale alarm report. Example 7 is outwith selected period and won't contribute to stale alarm report.
