While we're on the subject, why is it that nearly all these battery backups tout the fact that they have an alarm when on battery power? I hate those damn alarms. I have four battery backups at home, and when the power goes out it's a cacophony of beeping.
A certain person I know, once didn't even notice for about five minutes that he was having a power cut because the persistent, oddly unsynchronised beeping from the two UPSes in the sitting room
was indistinguishable from the sort of music he listened to anyway...
It wouldn't be too bad if only there was an easy way to turn these alarms off.
I have an APC Smart-UPS and the alarm can be turned off over the serial port; there's an option in the apcupsd config file.
