Abstract: The present disclosure provides methods, devices, and systems for controlling access to a controlled area. The method may comprise receiving a credential identifier in an access controller associated with an entrance to the enclosed area, and then authenticating the credential identifier. The method may then comprise sending an unlock signal through a solid state relay within the access controller to power a lock associated with but external to the access controller to unlock a door at the entrance to the enclosed area when the credential identifier has been successfully authenticated.
