Patent attributes
A system and method for sharing state information of an auxiliary door are provided. The system includes a main locking device and an auxiliary door with a state sensor. The state sensor is configured to detect and transmit state information to at least one of the main locking device and a room management system. The state information may include whether the auxiliary door is in an opened state, a closed state, a locked state, and/or an unlocked state. The main locking device is configured to transmit a notification based on the state information when a rotation sensor detects the rotation of an interior door handle and the state information indicates that the auxiliary door is in the opened state and/or the unlocked state. This notification may be sent to a mobile device and/or a status indicator.
