The Alarm system

This unit will continuously check for dangerous situations and
system faults while the system is running. When an alarm situation
occurs, an alarm message will pop up on the screen.
If you have enabled the siren, the alarm message will be followed by
an audible alarm.
The alarm is recorded in the alarm history so you can see the details
and take the appropriate corrective action.

The alarms dialog

The alarms can be setup in the Alarms dialog. This dialog also in-
cludes information about active alarms and alarm history.
The alarms dialog is accessed from the Utilities tab on the home
