ALARMS
On Battery – When the UPS is operating on the batteries, the On Battery LED will illuminate and the audible
alarm will sound once every five seconds. The alarm will stop once the UPS returns to the AC normal mode.
Low Battery Warning - The UPS will sound two beeps every five seconds when the battery reserve runs low.
This condition will continue until the AC returns or the UPS shuts down from battery exhaustion.
Weak/Bad Battery – The UPS automatically tests the battery’s condition and will illuminate the BAD
Battery/Overload/Fault LED and sound the alarm. This alarm will be repeated until the batteries pass a self test.
If the battery is weak, bad, or disconnected, the Bad Battery/Overload/Fault LED will illuminate and the alarm
will beep three times every thirty seconds until the battery is reconnected or replaced. It is recommended that
the UPS be allowed to charge overnight before performing a battery test to confirm a Weak/Bad Battery
condition.
Overload – When the amount of load attached to the UPS exceeds its power rating, the Bad
Battery/Overload/Fault LED will illuminate and the UPS will sound 1 beep every half second (AC and Battery
modes). This alarm will remain on until the excess load is removed or the UPS’s self protection circuit shuts the
UPS down.
UPS Fault – When the UPS detects a hardware fault, the Bad Battery/Overload/Fault LED will illuminate and
the UPS will sound a constant alarm. The fault condition, in some instances, may be reset by turning the UPS
off and then on.
