The dirscan probe alarms randomly at 07:00 which is outside the scheduled active time of 04:00-06:00.
Deleted the dirscan profile and its schedule
Recreated the dirscan profile and its schedule
Rt-click and updated the probe version from v3.19 to 3.20
Then as a result, the dirscan probe no longer alarmed randomly at 07:00+ outside the scheduled active time of 04:00-06:00.
Yet several weeks later, it alarmed again outside of the schedule.
So the customer moved the dirscan monitoring to a different robot/server.
Then there was no reoccurrence of alarms outside of the defined schedule.
