I know UPS issues have been covered in the past. As many of you may know, I'm 
an advocate of using them. Recently (within the past 2 weeks!) we have begun 
having UPS issues:

To wit: Sometimes, in the middle of the night (2 am - 4 am), two of our UPS's 
begin to click / beep. Not sound an alarm, mind you, just to click / beep 
quietly in a rhythmic pattern. I cannot find reference to what this might mean, 
though I think it means that the circuit being used is "browning out" power and 
the UPS is making up the missing power. 

Last night this happened at about 11 pm!!!

Eventually, the UPS's (we have many, but only two are involved in this 
situation) begin to blare. Then everything shuts down and they continue to 
blare 
until reset and recharged.

This is a very frustrating situation as it only affects two of our 4 UPS 
units (all in the same room, but possibly on separate circuits). It is also 
happening to a neighbor!!!!! Same scenario. Only our UPS's are far enough away 
that 
they don't wake us. Hers, sadly, wakes her when it begins to scream. (Please 
don't ask about the 2 am - 4 am thing. I sometimes work late into the 
night/morning.) 

We can tell when this scenario has occurred because a telephone answering 
machine ceases to work, and because my iMac is turned off. There are two UPS 
units involved. One has only the telephone answering machine plugged into its 
battery back-up sockets, and the other has only my iMac connected to its 
battery 
back-up sockets. Dedicated UPS's if you will. It is unclear if these are on the 
same circuit breaker or not. It's also weird that sometimes one of the UPS's 
is affected, and sometimes both of them are affected at the same time.

I have searched for references to sounds made by APC UPS units without 
success. These units are all relatively new (a higher capacity one was 
purchased 
last week for my computer in the hope that would help resolve the problem with 
my 
computer shutting down, but to no avail), and their batteries should be in 
good condition. 

Any help / advice / would be appreciated.
