The damn thing has developed the habit of bleeping at random intervals, I
tried running it flat and then reconnecting the mains supply but it still
keeps bleeping.

The user manual doesn't have a trouble shooting table and apart from the
random bleeping, the UPS appears to be working correctly.

Any suggestions?

TIA.


Check the voltage input. Perhaps it drops lower than the switchover
threshold.

I have 2 identical UPS boxes on the same ring main - only 1 is playing up.
