This may sound like a strange question, but is there a way to mute the
voice box of a UPS? I have a highly specialised application for one- I
need a mobile desktop pc (very cheap). I need to setup a pc for my
little girl so that she has music, video, and visualisations while she's
in her cot- which is mobile and moved from room to room. So I don't want
to shutdown the pc when in transit, and I certainly don't want any
shrieks when I unplug the power...
Just crack open the UPS box and cut the wires to the loudspeaker :-)
I thought of that- but how do you do that with those little sealed
units? I'm looking at a small consumer unit around 500-700VA.

I've got a couple of cheap APC models (RS500). You can turn off all
their alert signals using the apcupsd ( sysutils/apcupsd) program (
which is of course used for automatic shutdowns). The setting is stored
in UPS memory (probably flash or EEPROM) and is retained. This is good
actually, since one of these is pretty close to my bedroom ;)
So it can be switched off with the software? That could work for me...
I just confirmed with APC regarding this software setting, and they
confirmed it- but stated categorically that only the Window$ software of
their making could do it. Can you confirm the BSD software will do it?
I think I shocked the guy when he suggested just hook up to another
windows box to change the setting, then put it on whatever machine I
wanted, and I told him that was near impossible- "I wouldn't corrupt my
network with M$"!!!
I assure you, apcupsd has this option. Here is a direct paste from my
freebsd server:
Please select the function you want to perform.
1) Test kill UPS power
2) Perform self-test
3) Read last self-test result
4) Change battery date
5) View battery date
6) View manufacturing date
7) Set alarm behavior
8) Set sensitivity
9) Quit
Select function number: 7
Current alarm setting: DISABLED
Press...
E to Enable alarms
D to Disable alarms
Q to Quit with no changes
Your choice:
You can access this by running apctest as root. It is installed as part
of sysutils/apcupsd. You should however stop the apcupsd monitoring
daemon before running apctest.
