Abstract: The present invention provides a method and device whereby the occupant of a room can notify those outside the room that the occupant prefers no one enter the room, entry occur only after knocking, or unrestricted entry. Commonly understood symbolism is utilized so that a red indicator notifies that no entry is desired, a yellow indicator notifies that knocking should occur before entry, and a green indicator notifies that unrestricted or silent entry is permitted. The indicators can be remotely controlled by means of a control mechanism inside the room to allow someone inside the room to control the easily understood notice which can be viewed on an exterior wall of the room.
