In the old days (~thirty years ago), a UPS would have a "dry contact" that would be closed when there is power and it would open when power is removed. We would use an open serial port and wire the RTS line to one side of the contact and the CTS line to the other side of it. Then we set one signal high and monitor the other one and this would tell us when we had power. I am certain you could easily do something similar if you have a UPS with a relay contact. I don't know if they have them any more.
