Issue: UPSs are generally installed and placed in places not easily seen by a user (i.e., under a desk, in a wiring closet, etc). Therefore, in order to provide proactive warnings of changing UPS and power conditions to users, APC's UPSs have audible tones. An occasional single beep from the UPS is normal UPS operations. This means that the UPS is protecting the load. Below is a list of audible indicators and possible meanings. Please refer to your Back-UPS user manual for the complete list of which audible tones the unit you purchased has.

Product Line: All Back-UPS Families Environment: All Back-UPS Families Cause: 1.) The Back-UPS product is operating on battery power - This alarm indicates that the UPS has transferred from On Line operation to On Battery operation. The Battery Power Supplied outlets are now battery powered. 2.) The Back-UPS product has entered a low battery condition - This alarm indicates that the UPS has reached a Low Battery condition and will soon shutdown. The UPS can only operate on battery for a limited amount of time. In order to protect the unit's batteries from discharging too much, the UPS will shutdown and turn off its output. To warn you that the unit will soon shutdown, the UPS will sound this alarm 2 minutes before actual shutdown.

With optional APC management software, 2 minutes can be changed to give you more of a warning of impending shutdown. If you hear this tone, you should immediately gracefully shutdown your operating system to prevent data loss or corruption. 3.) Capacity Overload - This alarm indicates that the UPS has detected an Overload condition. If this alarm is sounded, try removing non-essential equipment.

4.) Unit failed a self test - Most Back-UPS products perform an internal self-test every 14 days, checking the integrity of the battery. If the battery fails the self-test, the 'Replace Battery' LED will illuminate. The Replace Battery LED is a WARNING that the battery may be near the end of its life, and replacement is typically recommended within 2-4 weeks. 5.) Disabling UPS audible alarm tones - When using the PowerChute Personal Edition software, the UPS audible alarm tones can be disabled.

(Not available on all Back-UPS Models) Resolution: 1.) The Back-UPS product is operating on battery power Tones: • 4 Beeps Every 30 Seconds (the amber On Battery LED will be illuminated). 1 beep every 5 seconds - If the input voltage is determined to be unsafe for your computer equipment, the UPS will transfer to On Battery. The alarm will stop once the unit returns to On Line operation.

Please refer to the technical specification section of your user manual for the acceptable voltage window. Occasional transfers to On Battery should not be a matter of concern, but rather, should be considered normal operation. The UPS is trying to provide clean, safe, and reliable power.

If your unit shipped with APC management software it may be possible to change the default acceptable voltages that the unit shipped with. Please see the help section of the APC management software for instruction to do this. - If the Frequency deviates + or - 5% this will also cause a Back-UPS product to transfer to battery power. Frequency distortions are most commonly caused by generators that are undersized. Always make sure a generator is 3 to 5 times the size of the total load attached to unsure it can maintain a steady output frequency. There is no way to change the +/- 5% deviation. - If the shape of the incoming power is considered 'too dirty', some Back-UPS products may transfer to battery power.

This is most likely the problem if you have already confirmed that the input voltage is within the acceptable limits. Most Back-UPS products have the ability to change their sensitivity to the shape of the input power from high to medium or even low. Please see your user manual for details as to how to adjust this setting. Note: If the power disturbance is brief, you may only hear the unit beep once or twice. 2.) The Back-UPS product has entered a low battery condition • Continuous Beeping (the amber On Battery LED will be illuminated) Note: This graceful shutdown will occur automatically if the APC management software is being used. 3.)Capacity Overload • Constant, Solid Tone (the red Overload LED will be illuminated) If the Back UPS emits a constant flat tone and reducing the load does not solve the problem please try the following steps: 1) Turn the UPS off.
