The double cylinder 97 Function ‘Classroom Intruder’ function uses a key to lock and unlock the door from the outside for opening or closing the classroom. In an emergency situation, it allows the teacher to use their key to lock the outside lever from inside the classroom thereby preventing unauthorized entry. Because it requires a key, it prevents the students from accidentally locking the teacher out of the classroom. The inside lever is always free for emergency egress.
