use what is already packaged for centos:

  apcupsd - apc ups
  nut - network ups tools

apcupsd is designed to run with apc brand ups.

nut is designed to run with apc and other brands.

both monitor ups and will shut system down via shutdown command.

i use apcupsd on my system with an apc back-ups rs 800 and have never
had problems.

during a 5 day power outage, i had change config so i could run system
when i used a gas powered generator to supply mains and voltage would
drop to a low of around 90 v.



peace out.
