indicated by horns, lights on the UPS, or both.
Select Active from the Events menu on the LCD screen to look at the Active System Events
screen. This screen shows any currently active alarms, notices, or commands.

events. When an alarm occurs, you should first check these indicators to see what type of
event has taken place. (For descriptions of the status indicators, see Reading the Status
