LED indicators.
The LED energy flow diagram shows the current status of the power supply, the power flow in
the UPS, and the state of the individual UPS components. Detailed description of each diode
below.
Table 5-1 A description of the meaning of each state of the LED indicator

Audible alarm
There are two types of acoustic signaling in the UPS. Both are described in the table below.
Alarm
Description
Two short alarms and one long one
Appears when events such as power outages occur.
