Alarms

queries provide data based on your specified time and date require- ments. For more information on performing queries, see page 39.

The generated data displays in a table with the same headings shown on the Main page (see Table 4 on page 31). This data is listed sequen- tially based on the time of an alarm’s change in state. The most recent change is listed first.

Rows showing the green icon show either:

•“Cleared”—an attribute has returned to “Normal” from one of the alarm states other than “Unknown”.

•“Normal”—an attribute has returned to normal state from the unknown state () and the description shows “State Change Unknown to Active”.

To return to the history request form from an alarm history table, click the History page selector.
