Shared Bathroom Privacy Lock

The Shared Bathroom Privacy Lock is an electronic system to secure privacy in bathrooms shared by two adjoining rooms. The system works as follows:

1. For access to the bathroom, press the Open button in your room.
2. Your bathroom door opens while the door to the adjoining room remains locked.
3. When you have entered the bathroom and closed the door, press the Open/Locked button inside, and both doors are locked for privacy.
4. To exit, press the Open/Locked button once more, and the door you came in opens while the door to the adjoining room remains locked.
5. A few seconds after you exit, both doors return to a locked position, and the bathroom is available from both rooms by pressing the Open button.
