CL625 Mortice Lock With Double Cylinder And Code Free Option

Check operation of the coded front plate

On the CL625 model a free passage function is available. This is identified by a black dot on the bottom left hand ‘P’ button. In normal operation the code needs to be entered every time to retract the latch. To put the lock into free passage mode, first press the random factory set code, followed by the passage set button. The lock will now be in code free access mode. To put the lock to code access only press the passage set button once followed by the C button.
See the code change instructions.  

The code may be entered in any sequence, i.e. 1370 may be entered as 0731 or any other sequence of those numbers. There are a total of 4,095 codes available, any of which may be entered in any order.

The CL625 model has a mortise lock and may be used as a new installation on a door, or where an existing lock is to be replaced.

IMPORTANT The mortise lock provided (fig.2) has features which are not found in most other locks and so it is recommended that you familiarise yourself with them as follows:

A. When necessary the hand of the latchbolt can be changed by removing the three screws holding the faceplate to the lockcase, reverse the latchbolt, and tighten the screw back up, ensuring that the latchbolt is central.

B. Put the key in the cylinder and insert it centrally into the lockcase. Fix it in position with the long bolt through the faceplate. It should now be possible to project and retract the deadbolt with the key, and also to retract the latchbolt.

C. The square latchbolt follower is in 2 parts: the inside ‘panic function’ follower will retract the latchbolt and also the deadbolt when it is projected. The effect of this is to ensure that it is not possible to accidentally lock someone in a room because the deadbolt is projected. The outside follower will always retract the latchbolt whenever the lever handle is depressed after a correct code is entered, but it will not retract the deadbolt.

The hand of the ‘panic function’ is determined as follows: the grub screws on the split follower facing the code side must be removed. This prevents the outside handle retracting the deadbolt.

NEVER remove the grub screws from both sides at the same time.

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.

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 below it.

2. Hold the 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 mortise.

3. Apply tape to the 16mm drill bit at 90mm from the top to act as a depth guide when drilling the mortise holes. Ensure the drill is level and parallel to the door face and drill the holes as indicated on the template. Remove the remaining wood with a chisel to leave a clean mortise hole which accepts the lockcase without forcing. With the lock in the mortise make sure that the forend is parallel with the door edge and mark the outline of the forend plate. Cut the outline with a Stanley knife to avoid splitting out when chiselling. Chisel a rebate sufficient to accept the forend flush with the surface.

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 the procedure on the other face of the door.

5. Drill the holes from both sides of the door to improve accuracy and to avoid splintering out the door face.

6. Install the lockcase in the door.

7. Cut three of the socket head bolts to the required length for your door. Approximate overall length should be door thickness plus 25mm to allow about 10mm of threaded bolt to enter the outside plate.

8. Take the BLUE or RED tipped spindle and fit to the code side according to the hand of your door (see diagram).

Fit remaining spindle to inside - non code side. 

9. Apply the front and back plates, with the neoprene seals in position, against the door, over the protruding ends of the spindle.

10. Fix the two plates together using the socket head bolts, starting with the top fixings. Ensure that the two plates are truly vertical and then tighten the bolts using the ‘T’ shaped Allen key. Do not use excessive force.

11.Check that the lever handles are correctly fitted for the hand of door. To change the hand of a lever handle, loosen the grub screw with the small Allen key, reverse the lever handle and fully tighten the grub screw.

12. Before closing the door, enter the code and check that the latchbolt will retract when the lever handle is depressed. Now check the operation of the inside lever handle. If there is any binding of the handles or the latch then loosen the bolts and reposition the plates slightly until the correct position is found, and then re-tighten the bolts.

13. Fit the double europrofile cylinder and secure it with the long screw through the faceplate. Fit the cylinder escutcheons.

14. Check that the deadbolt will project and retract by key, and that the key will also retract the latchbolt. Check that the inside lever handle WILL retract the deadbolt simultaneously with the latchbolt. Check that the outside lever handle WILL NOT retract the deadbolt.

15. Mark a vertical line on the door jamb half the door thickness away from the door stop. This gives the centre line of the strike plate. Align the strike plate template with the height line, with the arrow heads aligned with the centre line. Mark the fixing holes, and draw around the apertures for the latchbolt and the deadbolt. Chisel out the latch aperture to 12mm deep, and the deadbolt aperture to 22mm deep. Fix the strike plate with the top screw only and gently close the door. Ensure that the latchbolt enters its aperture easily and holds the door without too much ‘play’. When satisfied, draw around the final position of the strike plate, remove it, and cut a rebate to allow it to fit flush to the surface. Re-fix the strike with both screws.  

The CL625 has been designed so the code can be changed on the door in seconds.

The code chamber consists of 12 buttons from which the code is selected, and a ‘C’ button which is used to re-set the chamber after an incorrect entry, and which must always be used as the first digit of a code. Buttons may only be used once in a code. For example, 1212 is not possible. A CL625 code, or combination, can be entered in any order or sequence; e.g. 1234 can be 4321 or 1342 or whatever sequence is most convenient to remember.
With 12 buttons, a total of 4,095 different codes are available, any of which can be entered in any sequence. Most people will set a code in the range of 4 to 7 digits, and the total number of codes in this range is 5,434. The lock is supplied with a random factory set code (see code change card supplied with lock). At any time this can be quickly changed to a new code of your choice. Typically codes are 4 to 7 digits long. Shorter codes are possible (1-2 digits) but are not recommended.

Passage Free Mode
This feature can be identified with a black dot on the ‘P’ button. To set the lock in passage free mode enter the code followed by the ‘P’ button. The lock will now be in free passage mode. To put the lock back into code access only press the passage set ‘P’ button once followed by the C button.

Code Change Instructions

The CL625 model offers significant advantages over other similar mechanical digital locks by allowing the code to be changed in seconds on the door.

* Before changing code press the ‘P’ and ‘C’ button to ensure that the lock is not in free passage mode. 

1. Choose code.
2. Insert key and turn anticlockwise to stop for right hand hung doors, or clockwise to stop for left hand hung doors. Fig 1.
3. Push the code change tool onto each button in turn, pushing in the buttons approx 2mm turn anticlockwise 180°. All buttons should now be in the non code position.
4. Test that all buttons are in non code position by depressing the lever handle which should retract the latch. If latch cannot be retracted press ‘C’ buttons and repeat step 3.
5. To select a button as a code button, push code tool over button. Press in button with tool approx 2mm and turn clockwise 180°. Fig 2.
6. Now turn the key clockwise for right hand hung doors, or anticlockwise for left hand hung doors retracting the latch which will relock the code buttons. Fig 3.
7. Return the key to centre and remove.
8. Before closing door test code.

Fig.1 (Image shows right hand hung door - for left hand, turn key clockwise)

Removal of front load cylinders to repin or replace with cylinders by a different manufacturer
1. Remove handle and cylinder cover

2. Turn key 90° anticlockwise and remove the cylinder from boss.

3. To replace cylinder, reinsert and turn 90° clockwise. Replace the cylinder cover and handle.
* If intending to use a cylinder from a different manufacturer it is advisable to confirm beforehand that the new cylinder will fit the boss.
Note that the CL625 uses a 6 pin screw cap cylinder. If using a screw cap cylinder other than supplied, the tail piece from the Codelocks screw cap cylinder will need to be fitted as follows:

4. Hold down the control pin in the end of the cylinder and unscrew the cap.
CAUTION! DO NOT INSERT THE KEY IN THE CYLINDER ONCE YOU HAVE REMOVED THE SCREW CAP.

5. Refit the tailpiece, hold down the control pin and screw the cap on fully without tightening. Ensure the control pin projects to lock the cap.

Test the key operation
If the key is difficult to insert, or tight when turning, then the cap maybe too tight. Loosen the cap one notch at a time and try the key again. If the key inserts and turns OK, but is difficult to remove, then the cap may be too loose. Tighten up the cap one notch at a time. Adjust the cap until the key inserts, turns and removes easily.

Maintenance
No maintenance of the working parts is necessary. Do not oil. To maintain the finish the lock should be cleaned regularly with a soft cloth. A silicone spray or similar should be used to provide a protective film against grit and grime.
