Backup Beeps

upsBackup Beeps: a reader asks…

I have sleep apnea and use a CPAP while I sleep. We have frequent brownouts. I have just purchased 2 UPS’s (Prolink Pro700SFT 650va). The brownouts usually last between 2 and 20 minutes. I wrote the Manufacturer but was told I can’t shut the alarm off. I want to disable or silence the alarm so I can continue to sleep uninterrupted. How do I do this? Thanks in advance for your assistance.

First, I’m assuming you were looking for a lower-cost solution to your problem than a battery backup system that is designed for CPAP use. I see battery systems available from $260US and up from places like and

The Prolink brand of UPS are designed for computer systems and other consumer electronics backup needs, so the engineers designing them likely didn’t consider the need for beep silencing such as in your situation. Certain other brands of UPS devices do offer the capability to disable warning beeps, notably APC Back-UPS and CyberPower. I should note that this doesn’t apply to every model in either brand, most of the smaller and cheaper units don’t have any way to change the warning beeps. Larger and more expensive models do.

  1. temporarily plug in the UPS to your computer
  2. install and run the software, and turn off those system beeps
  3. then unplug the UPS from the computer and relocate it to your bedroom

Although the software runs on your computer, the notification setting is made on the UPS itself, which allows it to work even when the computer’s not attached.

I know that certain models of APC Back-UPS system can use their PowerChute Personal Edition software, which includes the ability to disable those annoying beeps. One other possibility would be a home theater battery backup system – those are designed specifically for situations where you don’t want annoying beeps. But the cost of those systems is generally quite a bit higher than either the CyberPower or APC options.

If returning is not an option and you have to use the Prolink systems, then you have a few other options:

This isn’t for the average consumer, you’d have to first remove the internal battery pack and then unscrew the case and locate the beeper. That is usually a small, can-shaped cylinder wired to a circuit board. Removing it can be tricky though, so I wouldn’t recommend this for most people who aren’t comfortable dealing with wiring, circuit boards and a soldering iron.

Second, and by far the simplest solution is to just relocate the UPS units to another room in your house, one far enough away so you can’t hear them beeping. Then run a long extension cord from there to your bedroom and the CPAP unit. A low-tech answer, but one you might consider, particularly if you can’t return the Prolink systems and are willing to live with a cord running down your hallway.

  1. Alina @ APC Smart UPS

    The Smart-UPS is APC’s business line and should be “smart” no matter where it is installed. It’s perfectly valid for a prosumer to buy a business-class device because s/he needs business-class performance.

    • The OP simply needs an UPS that has the ability to turn off the beeps. IMO, that’s not a business-class performance level. But you’re correct that APC’s Smart-UPS line does support the Powerchute software to allow you to turn off the beeps. So does the cheaper Back-UPS line, except for the lowest end of the models.
