I have a pair of APC S-15s which are dead silent on standby and on
battery. The alarm is defeatable but the fan does operate very
briefly at switch on and change-over to battery as part of the
diagnostic operations. Other than that, silent and cool-running.

If anyone knows of more relevant newsgroups to post this to, we'd
appreciate the info.

We're trying to find an uninterruptible power supply (~1000VA or
more) for a quiet environment (residential living room). Which
means the unit must not have any fans, buzzing noises etc while it's
operating, and above all else, must have an option to disable any
audible alarms it might have.

We've been searching for a month and haven't found anything so far.

Any help greatly appreciated,

Tom
