In daily life, why does my apcpack UPS beep differently? This is because your machine is being protected by apcups. In case of power failure, apcups will provide sound alarm for users. When the ups beeps, it means that the UPS is working and protecting your load. When the back ups is running on battery, you may hear the following sounds:

4 beeps every 30 seconds (with the battery running yellow indicator on). The UPS has switched to battery powered because it has detected that the mains supply cannot provide a safe input voltage to your device. It is normal to switch to battery power occasionally. UPS can provide pure, safe and reliable power supply. The alarm will stop after the UPS is switched back to normal power supply. If your UPS is equipped with apcpowerchute ® management software, you can also change the default switching voltage range.
