I'm not sure what is going on with your UPS units but I think the best
solution to your particular problem would be to insert a switch in series
with the sounder. Then you could leave the unit on without fear of
bothering the people upstairs.

Your problem got me curious so I did a little quick research. According
to Schneider Electric Storing a UPS with the battery connected can cause
permanent battery damage within a few days to a week. A UPS should be
stored after complete battery recharging with the battery disconnected.
The better quality bnc connectors are usually nickel-plated brass. If you
scrape a small area the brass color will show under bright light. Also,
many of the cheaper connectors use dielectric material that will soften
during soldering.

pencil on a piece of paper as was done in an
episode of the old Macgyver TV series :)
