5.3 Audible alarms
The UPS features an audible alarm that beeps to indicate certain conditions
(see Secs. 5.3.1–5.3.4). Operation of the audible alarm is configurable using
UPS monitoring software (see Sec. 5.5.4).
5.3.1 On-battery alarm
The UPS emits four short beeps every 30 seconds when the UPS is operat-
ing on battery power.
5.3.2 Low battery
The UPS beeps steadily to indicate that less than 2 minutes of power
remains before shutdown from battery exhaustion. The low-battery warn-
ing interval is configurable (see Sec. 5.5.4).
5.3.3 Replace battery
The UPS emits short beeps for 1 minute if the UPS’s batteries fail the self-
test. If the UPS is left operating in this condition, the UPS emits short beeps
once every 5 hours until a successful battery test is completed.
5.3.4 Overload
The UPS emits a loud, sustained tone when overloaded. When the load
exceeds the UPS’s rating during on-line operation, the alarm sounds until
the overload is removed. If the overload occurs during on-battery opera-
tion, the alarm sounds until the UPS Enable switch on the rear panel is
turned off.
