Option Description
Duration An active alarm means that at least one condition occurred that
triggered the alarm, and the condition still holds true. When the
condition of the alarm no longer holds, the alarm will remain visible

recommended.
After the condition and the alarm duration have expired, the alarm
becomes inactive, although it will remain visible in the historical
logs. (You can view the historical logs using Forensic Analysis.) You
can also clear an alarm before the duration expires.
