Alarm on notification bar


If you open the clock app and click on the alarm page, you should see all the alarms you have created, if any of the little alarm icons next to them are green it means that that alarm is enabled, tap the icon to turn off the alarm, this should make it go away.

Check the connections on the batteries. One or more may be loose or corroded. Also check the fuse for the batteries. It may have blown.

Powerware ups 6kv indicates Bat disconnected


1st does this have external battery modules or is it only the Internal batteries on this unit? You can disconnect the EBM's and the unit doesn't alarm even removing the internals with EBM;s attached won't cause an alarm. But it you only have internal batteries, open the front cover by pressing in the sides on the bottom left and right and pull it out and up at the same time revealing a black cable with a small anderson connector, make sure it is connected. you can pull the batteries out to check them to be sure they are properly seated. By the way the UPS in the picture only went to 3000va so is the 6Kv a different model?

Constant alarm but works fine otherwise


Jordan,

It probably burned up one of the capacitors on the board that signal the UPS to turn the alarm off. I've had this happen before and I unplugged everything, turned the UPS off, disconnected the batteries and then opened the UPS up to cut off the tiny, annoying, surprisingly loud speaker. I then put everything back together and that was the end of it :)

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

APC back-ups es500 alarm continuously sounds why we power it off and alarm stops everything works fine then we power it back on and alarms sounds again


It means it has an internal fault. if still under warranty period, just call APC and ask for replacement. if it out of warranty bring it to service center or better if you have to buy a new one because as far as i am concerned repair cost of this unit is much expensive than a new unit
