Codelocks CL5020 Mortice Latch with Double Cylinder - Manual (Page 10)

IMPORTANT The Anti-Panic Mortice Lock has features
which are not found in most other locks and so it is
recommended that you familiarise yourself with them
.
The hand of the latchbolt is changed by removing the three
screws holding the faceplate and reversing the latchbolt.
Insert the cylinder centrally in the lockcase and fix in position
with the long bolt through the faceplate.
Using the key it should be possible to double-throw the
deadbolt, retract the deadbolt, and retract the latchbolt.
The latchbolt follower is in 2 parts, with 2 set screws visible
in each part. Determine which side of the lock will be the
outside and remove the set screws from that side. DO NOT
remove the set screws from both sides.
The outside handle will now retract the latchbolt but
NOT the deadbolt.
The inside handle will now simultaneously retract the
latchbolt AND the deadbolt if it is thrown.
This safety feature ensures that it is not possible to
accidentally lock someone in a room by throwing the deadbolt
from outside.
Throwing the deadbolt will deny access to code users when
appropriate.
All door locks should be installed with a degree of precision
to ensure that all components are horizontally and vertically
accurate in relation to each other, and in relation to the door.
Do not install the lock where it will involve cutting into a joint
between the door stile and a mid-rail.
INSTALLING THE ANTI-PANIC MORTICE LOCK FOR
MODELS CL4020 AND CL5020
INSTALLING THE ANTI-PANIC MORTICE LOCK FOR CL5020
1 Lightly mark a height line on the
edge and both faces of the door, and
the door jamb, to indicate the top of
the lock when fitted. Mark a line
down the centre of the door edge,
extending above the height line and
300mm (11
13 /
16
”) below it.
2 Hold the mortice lock template
against the edge of the door with the
top in line with the height line, and
with the arrows in line with the
‘Centre of Door Edge’ line. Mark the
positions of the fixing screws, and
the holes to be drilled for the
mortice.
3 Drill the marked holes 90mm (3 17 /
32
”)
deep and form the mortice for the
lock.
4 Fold the template accurately along
the dotted line and tape it to the door
face with the top in line with the
height line, and the fold on the door
edge. Mark the centres of all the
holes to be drilled. Remove the
template and repeat on the other face
of the door.
5 Drill the holes from both faces of the
door to improve accuracy. Do not
drill right through the door as this
will damage the door when the drill
breaks through.
