describe the nature of the alarm condition. Scroll through multiple alarms using the Up and
Down arrow keys on the Center button. Refer to the section, "Status," in Chapter 3 for more
information on displaying the alarms using the LCD menu.
The Main Menu displays active alarms for the entire system. Under the electronics modules
M1-M4 menus, only the individual electronics modules that have alarms are indicated. As a
result, you can pinpoint individual modules that are having problems.
Refer to the section, "LCD Alarm Troubleshooting," in Chapter 5 for causes and suggested
actions for all alarm conditions.
Silencing an Audible Alarm
To silence the alarm, press the Test/Alarm Reset button (1) and hold for one second.

IMPORTANT: Although the Test/Alarm Reset button silences the audible alarm, the condition that
caused the alarm still exists. See Chapter 5, "Troubleshooting," for information on what to do if the UPS
detects an alarm condition.
The silencing of the alarm is based on the current set of alarms that is present when the button is
pressed. If the alarm set changes and at least one alarm condition still exists, the audible alarm
reactivates.
If the condition that caused the alarm is a utility power failure, the alarm is silenced shortly after utility
power is restored.
