Hi Branum,
If you look at the first video in the unit, there are two *operating* voltages that are represented in the various examples that he showed: 120vac and 12vdc.
5vdc is usually for a communications line of some sort. So when you see that, it is sending a signal that indicates the status of the door. It is not operating the lock.
Does that help?
