What is the difference between the QET170 and QET180 night latch escutcheon?

The QET170 is an ANSI 03 night latch function where the lever is always locked and the key is used to retract the latch. The QET180 is an ANSI 09 night latch function where the lever is locked and the key is used to unlock the lever. The lever is then used to retract the latch. The key can only be removed when the lever is locked.
