Responding to System Events
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 youknow exactly what event caused the
change from Normal mode. System events can be indicated by horns, lights on
the UPS, or both.
Select Active fromthe Events menu on the LCD screen to look at the Active
System Events screen. This screen shows any currently active alarms, notices, or
commands.

System Event Horns

The system event horn beeps according to the type of event it is signifying:
·When the UPS detects an alarm that requires your attention, the hornbeeps at
½-second intervals.
·When a notice occurs, the horn beeps at 2-second intervals.

System Event Lights

The status indicators on the UPS MonitorPanel work in conjunction with the event
horn to let you know when the UPS is operatingin any mode other than Normal.
Only the Normal indicator is visible during normal UPS operation. The others light
to indicate alarms or events. When an alarm occurs, you should firstcheck these
indicators to see what type of event has taken place. (For descriptions of the
status indicators, refer to the “Reading the Status Indicators” sectionof Chapter 5.)
