Site alarm roll-ups

For each site record, the monitorAlarmRollUp application periodically rolls ups the alarm counts for each alarm category based on the existing alarm counts of all stations associated with that site.

The following information is kept in each site record:

• Highest active alarm severity at the site (mostSevAlm)

• Color of highest active alarm severity (mostSevAlmCol)

• Number of alarms of each severity (alarm_counts)

  Note: Unlike the station record, during the roll-up of alarms the site record just stores the above information in the RealTime database (RTDB). The site record itself neither flashes nor changes color.

Refer to the following table to determine which element in the alarm_counts array field contains the count for which severity.

For more information on the Alarm Count Index associated with alarm severities, refer to Station alarm roll-ups.

To view the relationship between fields on the Site Summary window, which displays the number of alarms for each alarm category, and the corresponding internal fields, refer to the table in Station alarm roll-ups. For example, the path to the internal site table field for UnAcked Low would be <site>.<record>.alarm_counts[5].
