Entrance Lock
Latchbolt retracted by knob/lever from either side unless outside is locked by 20o rotation of thumbturn. Deadbolt thrown or retracted by 90 degree rotation of thumbturn. When locked, key outside or knob/lever inside retracts deadbolt and latchbolt simultaneously.
Outside knob/lever remains locked until thumbturn is restored to vertical position.
Throwing deadbolt automatically locks outside knob/lever. Auxiliary latch deadlocks latchbolt when door is closed. Inside lever is always free for immediate egress.
門外用鑰匙上鎖，門內用轉鈕或功能切換按鈕上鎖，方舌一旦伸出，即自動鎖住門外把手，上鎖後，門外用鑰匙開鎖，門內用把手可以使方舌和斜舌同時縮回開門。
當外把手被製成是不可解鎖的或者方舌處於伸出狀態時，斜舌是帶有保險的。
當方舌縮回時，斜舌可用擋塊或除鑰匙之外的機械方法來解鎖
