ABSTRACT:
The electric lock system operates to block access to the room when a guest key has been used and the guest is detected as being present in the room. The lock blocks access to hotel staff and provides the guest greater privacy in the room. The lock system employs an electronic lock in combination with a motion detector for detecting the presence of the guest in the room.
