How it works
Classroom function, ANSI E0171
A key in the outside lever locks or unlocks it. The inside lever is always free, so nobody gets locked in. Common on classrooms and meeting rooms.
Outside lever
Locked or unlocked with a key from the outside. It stays that way until the key changes it.
Inside lever
Always free. Anyone inside can leave without a key.
