Sorry if I jump in the thread. When it comes to detecting a power
outage and shutingdown nicely your server, a cheap/easy way is for the
server (on the UPS) to check through the network for a low grade PC
(not on the UPS). If the low grade PC is down, it means the power is
off and the server should consider a shutdown.

Dirty trick, but it works.

Best regards,
