When the UPS system is running in Normal mode, it continually monitors itself and the incoming utility power.
In Battery or Bypass modes, the UPS may issue alarms to let you know exactly what event caused the change
from Normal mode. System events on the UPS can be indicated by horns, lights, messages, or all three.
Select EEvveennttss from the menu bar on the Main Menu screen to look at the Active System Events screen. This
screen shows any currently active alarms, notices, or commands. For more information on using the Events
screen, see 8.2.2 Event Screens.

The system event horn beeps to alert an operator that an event needing attention is taking place. Horn 1 cycles
at a one-second rate.

The status indicators on the UPS control panel work in conjunction with the event horn to let you know when
the UPS system is operating in any mode other than Normal. Only the Normal indicator is visible during normal
UPS system operation. The other indicators illuminate to indicate alarms or 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 8.5 Reading the Status Indicators.

When a system event occurs, a message appears on the LCD in the UPS status area. This message is also
written to the Active Events log and may be added to the Events History log. The messages are divided into
four categories: alarms, notices, status, and commands. The following tables contain the events displayed on
the Events screen of the control panel.
