Subject: UPS shutdown happens how?

I just got a new UPS at work which has a USB cable connection.
If I look at the power settings in gnome-control-center, it claims to know I'm on a UPS, so I guess it knows how to talk to it.

I told it to shutdown when battery power is critical, but I'm wondering who the heck recognizes that. I don't run a gnome session, so is there some daemon that needs to be working for it to actually shutdown cleanly?

As with all in Linux-realm, there are several ways  to obtain something.
Not all UPS has a proper working intercase, or have one that is not compatible.

A friend of mine solved it in a different way: On his UPS-protected machine, he pinged every minute  a small box that is not UPS-protected.
No reply? Decent shutdown!  Also easy to test...
