Annunciator
The graphical annunciator panel emulates a physical annunciator panel. Indicators on the
graphical panel are backlit and have a description of the alarm condition that lights each
indicator. The annunciator panel status window shows the alarms that are active.
To reset an active alarm, first highlight the active alarm using the navigation keys, then
press the reset button to reset the highlighted alarm. If no indicator is selected, all alarms
on the page are reset by pushing the reset button.
