System Events Main Screen
When the UPS system is running in Online mode, it continually monitors itself and the
incoming utility power. In Battery or Bypass modes, the UPS may issue alarms to
display exactly what event caused the change from Online mode. System events on
the UPS can be indicated by horns, lights, messages, or all three. See Figure 7‐22.

System Event Horns
– The system event horn beeps to alert an operator that an
event needing attention is taking place. The horn cycles at a half-second rate.
S
System Event Indicators
– The status indicators on the UPS control panel work with
the event horn to let the operator know when the UPS is operating in any mode
other than normal. Only the ON indicator is visible during normal UPS system
operation. The other indicators illuminate to indicate alarms or events. When an
alarm occurs, first check these indicators to see what type of event has taken
place. For descriptions of the status indicators, see paragraph 7.3.1.
S
System Event Messages
– 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 History Log. The messages are divided into four
categories: alarms, notices, status, and commands.
