Important: The Key Override itself does not retract the
latch or deadbolt. Do not use too much force when turn-
ing the key as this may damage the unit. To retract the
latch, turn the key clockwise until it stops, release the
key and turn the lever handle (H). See page 19
!
Note: The lever handle must stay in the horizontal posi-
tion when turning the key (do not try to turn the key while
turning the handle) or the override mechanism will not
work.
!
Important: Always keep the door open while installing and
verifying the functionality of the 79 Series lock with the
keycard or key override. Do not close the door until you
are certain that you have installed the unit correctly.
