From mod description:

This addon adds new locking door system.
Doors can be unlocked to allow enemies and prisoners to pass by (only races that have inteligence "humanlike" or above).
Note: In order to unlock/lock door, colonist must "flick" the door.
Doors can exclude visitors (wanna lock some traders?).
Pet doors for small animals can now be added to doors.
Doors can be assigned to colonists (you can simply restrict rooms to specific colonists without allowed area manager).
New Flicking job: Locking/unlocking doors, it has higher priority than normal flicking job. ("Flicking" doors is needed).

Doors can be unlocked to allow enemies and prisoners to pass by (only races that have inteligence "humanlike" or above).
yes i see this but how. there is no option for prisoner only? is it warden job automaticly?

let me reask in a diffrent way. How does this work?

You can't set door to "prisoner only" as desc. says, why this should be a thing? Prisoners aren't on your side. If you want to "control" it that way, unlock and lock doors manually. For example lock doors when raid is coming.

It's working as it's described:
- if you click "unlock the door" will be unlocked so all humans can pass by.
- you can forbid vistors by clicking "forbid vistors" etc.
It's really easy to use. You can add "click on option to enable" to desc and thats all.
