Hello,

Could you please provide the model and serial number of this UPS? Also just to clarify, your UPS is emitting a long constant beep with no indicators or lights on, correct?

Thank you,

Hi,

Sorry for the inconvenience. When the UPS emits a constant tone that indicates the unit is overloaded. If there is no load and it emits a constant tone that would indicate an internal fault. Have you tried to reset the UPS? 

To reset 

1: Disconnect any attached load.

2: Unplug the UPS from the wall socket.

3: Disconnect the UPS' internal battery.

4: Push and hold the "On" button on the UPS for 5 seconds

5: Reconnect internal battery.

6: Plug UPS in to known good power source.

7: Turn UPS on.

If the reset procedure does not correct the issue the unit should be replaced.
