When actuating a handle or a push bar / touch bar, the counter case’s drive bar rods are retracted. The active door leaf lock latch bolt and dead bolt are pushed back at the same time. When the inactive leaf is returned to the locked position, the lock 4685 latch automatically triggers the independent locking on the drive bar rods above and below. The door can only be closed after this locking action.
