Schlage does offer a "time out" mortise lock as a special request only.
DESCRIPTION:
A modified Schlage L9010 with no trim on the inside.
When the lock is in a natural position the lever will be horizontal and the latch will be retained inside the lock case.
The outside lever, when held up, will project the latch into the strike and prevent exiting from the interior.
As soon as the outside lever is released the latch retracts and allows the door to be pushed open from the inside.
Lock case is handed and cannot be rehanded in the field
