Delayed Alarm Reporting
Any metering channel can be configured to delay alarm reporting for a preconfigured duration,
as specified under the Alarm Delay heading. When a delay is configured, the channel must be
continuously out of tolerance for the duration of the delay before the alarm will be logged or
reported.
Rearm Delay
The ARC Plus has a built-in mechanism to reduce multiple alarm reports due to a single alarm
event. An out-of-tolerance metering channel that returns to tolerance must remain within
normal limits for a period of time before a new alarm is issued on that channel. Use the Rearm
Delay column to specify this period.
For example, a channel configured to cause a high temperature alarm immediately upon
reaching 90 degrees will report the alarm as soon as the temperature reads 90. However, if the
temperature decreases to 89.9 and returns to 90 after less than the rearm period, a second
alarm is not issued.
