Shutdown software/app available?

Good morning,

New member here. I just migrated to a PR4100 NAS after many years running a Seagate Blackarmor in my home office. I am generally happy with the upgrade. My NAS is attached to an APC UPS and the software sees it an reports battery charge state but I do not see any option to shut the NAS down on power failure like I had on the Seagate product. Can anyone suggest how to accomplish this as we experience fairly regular power outages in my area? Thank you in advance for your assistance.

I don’t have an APC but I know there’s a menu where you can setup your nobreak. Maybe the option is there.
