Smart UPS intermittent single beep for no reason! Why???

[BillP]

I have a Smart-UPS 1400, rack mount.  It started indicating insufficient battery capacity a couple of days ago.  Blinking battery lights, and occasional burst of multiple beeps.  I should point out these batteries are 3 months old.

So I ran the calibration routine, which helped a bit, but the runtime was still way low.  But the low battery alerts stopped.  However it has started doing this strange thing where every 15 minutes it lets out ONE beep.  I then reset the battery constant, which greatly upped the runtime.  And it keeps beeping every 15!

There is absolutely nothing in any of the logs, lights, or anywhere that indicates any other sort of problem.  When it beeps, nothing blinks, it is not switching to backup.  Nothing.

Now my assistant at work moved all the loads off, unplugged it, and shut it off.  He says it is still beeping every 15.

Arrrgghh!  If someone can give me a clue what this might be about, I'd be most grateful.  This is in a radio station and it is more than just annoying.

It wasn't beeping for no reason.  It wasn't beeping!  TWO pieces of equipment in the same rack developed issues at the same time.  No one knew the fiber modem could beep due to problems.  And both the modem and the UPS sound identical.  Sigh.  Well, at least we learned all sorts of things about both pieces of equipment.

Joseph,

Glad that is resolved for you! One beep every 15 minutes is not a characteristic alarm of APC products so we may have had a wild goose chase.
