Back UPS ES 550 Beeps each night at same time

This was originally posted on APC forums on 10/12/2007


I need some advise on how to remedy the annoying beeping that occurs each night around the same time form my Back UPS ES 550. I have been using this UPS for the past 2 months without any issues. Just this week, however, the alarm started tripping every night around the same time and there has not been any power failures in the house. Any ideas?

Although you are not experiencing a total power loss, this does not mean that the quality of your utility power is 100% at that exact moment. Power Sags and Dirty Power (Total Harmonic Distortion) can not always be seen with the naked eye and are just a couple things which could cause the unit to switch to battery.

You've indicated the UPS beeps, but you have not mentioned what it sounds like and for how long. This audible indications can really tell you quite a bit about the UPS and what it's seeing. If this is occuring late at night, it's possible the power company is switching grids or adjusting their power generation to conserve energy.

I'm having this same problem.

My UPS isn't connected to the computer (other than with the power chord).

It goes beep beep beep beep at the same times of the day and night every day.

It beeps at 9:50 PM and 1:50 PM every day.

You can either try to figure out what's causing the unit to go to battery at these times (other equipment kicking on & causing voltage sags on the line, dirty power, etc) or disable the alarms via the software, as mentioned earlier.

Hello,

What type of alarm are you getting?

You can use the PowerChute Personal Edition software that comes with the UPS to disable all alarms, or even disable alarms during a certain time. The software may also tell you what is causing your UPS to alarm as well.

Thanks.
