Question about APC Back-UPS Pro 650 UPS System

1 Answer

My APC keeps beeping.

I just purchased my APC UPS ES 725 and when I turn it on, it starts with a short beep to let me know that it powers on, and it worked fine for about 4 houars. But after that, the alarm went off and it would not stop. Ever since that, it will only alarm. I don't understand it.

    Yes, this is the 3rd one I have had--they keep replacing. I have never had this problem before. Everything is connected as it should be. There are no brown outs and everything is plugged in accordingly. Depending on the day, it will beep all day. Hate it!

    Comments have not been helpful. Have done all that you are suppose to do including connection, downloading software, etc.. Mine keeps beeping and APC has exchange it twice. I don't get it...can't be the battery and cannot be a brown out cause my system doesn't go down. Maybe there is a potergeist in the wall. Doesn't happen everyday--some days-all day, some days--one to four hours, some days--not at all. Clueless with APCs.

    Firstly, have you connected the UPS cable to your computer and installed the PowerChute software? This software will be able to tell you more exactly what it going on.



    Secondly, on the UPS, is the "Building wire fault" light on? If it is, then it means that your power outlet is badly installed. It may be because the polarity was inverted or because the ground is not connected.

HOW DO I KEEP MY MINUTE MAN BACKUP TO STOP BEEPING?


If you connect it up to a Windows computer with the supplied (goofy-looking) USB cable and install the APC Monitor progam "Powerchute" available on the APC web site, you can set all the activity levels and tell it just when to beep the beeper, or turn it off completely. I have two of these in my house, and have set them to never beep. The cable is goofy because it is USB on one end and a network-type on the other end.

Apc beeping twice every 2 seconds


The battery inside the APC is "weak", and the "beep" is telling you to replace the battery inside the APC, or, maybe cheaper, to buy a new APC.

Verify that the usb to ups cable is pluggled in properly. Also you may not have a good ground. Disconnect the ups and plug it in another outlet to test with nothing else plugged into it, to see if it still beeps. You can also try and upgrade the ups software from apc.com

What does it mean by the beep sound from the UPS ES 350 unit?


Ok, 3-4 years is a much as you can expect from an ups battery so replacement is indicated. The beeps are letting you know the battery is not able to keep up with demand. So either you have recently added to the system or the battery/s failing.

Beeping


These UPS systems do a self check everytime you press the power button. If the voltage in the battery is too low, you'll get a long drawn out beep. A new battery should solve that problem and it is even economical with a unit this size. Here's a link: http://batteryinternational.com/apc-backups-es-be350es-ups-battery-ups-batteries-f1.html

Simply remove the single phillips screw on the bottom of the unit and remove the battery cover. Replace battery and that's it. Very simple to do.

UPS shuts off intermittently and beeps


More than likely it just needs a new battery. If the power is sagging (called a brownout) the UPS is trying to switch over to the battery to keep the power consistent. The beeping is probably a code that indicates there is an issue with low voltage on the battery. New batteries are around $20-25. Here's a link to the replacement battery: http://batteryinternational.com/apc-backups-es-be350es-ups-battery-ups-batteries-f1.html

Hope that helps.

1) Switch Off the UPS and unplug all Loads (like System, Monitor etc.) from UPS.
2) Switch Off the AC Power (Input Power to UPS).
3) Press the UPS Power Switch constantly unless you hear 2nd BEEP Tone. As soon as you are hearing 2nd BEEP Tone, Release the Power Switch.
4) This is COLD START of all APC UPS that will reset any internal problem.
5) If, however, the problem persists, contact APC.
