I get an alarm with continuos beep sound everytime I plug in the unit, even without load


Time to change the batteries. Open the UPS and get the battery type numbers and spec written on the batteries. Locate a local battery distributor and you can order batteries. APC uses industry batteries.

The batteries last an average of 2 to 3 years. They wear out inside. You can also order APC original batteries if you feel insecure about purchasing them from a battery dealer. APC will charge more for the batteries, but they will be original to the UPS type.

After a power outage, the alarm keeps sounding. I see others have had this problem but I can't find the solution. Help


The alarm is sounding because you have a low DC Buss. The alarm will go alarm will go away once the DC buss is at the min. threshold. Your batteries may be getting weak. Think about replacing

Continuous Beeping (theamber On Battery LED will be illuminated)
This alarm indicates that the UPS has reached aLow Battery condition and will soon shutdown. The UPS can only operate onbattery for a limited amount of time. In order to protect the unit's batteriesfrom discharging too much, the UPS will shutdown and turn off its output. Towarn you that the unit will soon shutdown, the UPS will sound this alarm 2minutes before actual shutdown. With optional Powerchute Plus software, 2minutes can be changed to 5, 7, or 10 minutes to give you more of a warning ofimpending shutdown. If you hear this tone, you should immediately gracefullyshutdown your operating system to prevent data loss or corruption.
Note:This graceful shutdown will occur automatically if Powerchute PLUS software isbeing used.

Constant, Solid Tone (the red Overload LEDwill be illuminated)
This alarm indicates that the UPS has detectedan Overload condition. If this alarm is sounded, try removing non-essentialequipment. The alarm will remain until the load is reduced. To determine ifyour UPS is capable of handling the equipment you want to protect, visit APC'sSizing Guide at www.apcc.com/sizing.

Continuous Beeps for One Minute; RepeatedEvery 5 Hours (Replace Battery LED will be illuminated)
This alarm indicates that the UPS has failed itsSelf-Test of the battery. The unit will continue to sound this alarm until theunit passes the test. Try to let the unit charge for a few hours and thenperform another Self-Test (Press and hold the on/off button until the second'chirp', then release). If it fails and the unit is still in-warranty (twoyears from date of purchase), then contact APC. If the unit fails and its outof warranty, then order a replacement battey cartridge through your reseller,distributor, or from APC's web site.

Battery test failed


1. Replace the batteries because they NEED to be replaced. It is not wise to ignore alarms.

2. Remove the battery backups. Without good batteries they are useless so why waste your time silencing alarms. Just make sure that the computers are plugged into a surge-protected outlet and you save your work frequently when there is bad weather.

FYI: Retail UPS batteries are only good for 2-3 years and high-end commercial batteries are only good for 3-5 years.

I hope this helps.
