The CL525 is a heavy duty Mortice lock with double cylinder, 3 keys, Code Free option and anti-panic safety feature.
The outside lever handle will retract the latch after a correct code is entered. The spring loaded latchbolt will lock automatically when the door is closed. The key retracts the latchbolt for entry without using a code. The key controls the deadbolt position. When the deadbolt is projected it denies access by code. When the deadbolt is projected the safety feature allows the inside lever handle to retract the deadbolt and the latchbolt, preventing people being accidentally locked in.
The key can be used to open doors for management functions such as security and cleaning.

Tools Required
Check operation of the coded front plateNote the slotted turn within the bottom left hand button. If the slot is in the vertical position it signifies that a code is needed each time to operate the lever handle. Enter the code from the code card provided in the box, the lever handle should turn fully to 80 degrees, and then spring back to horizontal. Enter the code again, turn the slot to the horizontal position and the lock will be in code-free access mode. Return the slot to the vertical position and after one further free turn of the handle the lock will be in code control mode again. Turn the front plate over and note that the red tipped tumblers inside correspond to the code. The code may be entered in any sequence, i.e. 1370 may be entered as 3710 or any other sequence of those numbers. There are a total of 1,023 codes available, any of which may be entered in any order. If you intend to change the code you should do it, if convenient, before installing the lock – see the Code Change instructions. Model CL525 is a complete locking unit with all the parts necessary for a new installation, or the total replacement of an existing lock. |

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: 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 two of the black 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 the butterfly spindle to the inside, non-code side.  |
|
| 9. 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. 10. Apply the front and back plates, with the neoprene seals in position, against the door, over the protruding ends of the spindle. 11. Fix the two plates together using the socket head bolts, starting with the top fixing. Ensure that the two plates are truly vertical and then tighten the bolts using the ‘T’ shaped Allen key. Do not use excessive force. 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 CL525 code chamber consist of 10 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 CL525 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 10 buttons, a total of 1,023 different codes are available, any of which can be entered in any sequence.
The lock is factory set with a randomly selected 5 digit code starting with the C button. The code is not recorded by the factory. The code can be changed as often as required to any other 5 digit code. Every new code must start with the C button. Using the spare tumblers, one red and one blue, the code length can be changed to 4 or 6 digits. Shorter codes are possible, but 1 or 2 digit codes are not recommended.
Code Change Instructions
Note: Before changing the code make sure that the lock is in Code Control Mode, with the slot in the bottom left button in the vertical position.
1. Take your CL525 lock off the door by unscrewing the 2 bolts in the backplate.
2. Press the C button to reset the chamber and place the lock case on a flat surface with the buttons down.
3. Remove the 4 red screws and carefully lift off the code chamber plate. Check the all 12 springs are held in place on the plate.
4. Note that the red tipped code tumblers correspond in position to the existing code. The blue tipped non-code tumblers fill the other positions. The C tumbler is not colored.
5. Hold the lock in your hand and depress the C button. Keeping the C button depressed use tweezers to re-position the tumblers to correspond with your new code. The square notches of ALL tumblers MUST face outwards, with the colored tips ON TOP: see diagram below. Do not force the tumblers in.
N.B. Holding the C button depressed whilst removing or replacing the tumblers is essential to avoid damaging the internal mechanism. Do not attempt to reposition the C tumbler.
6. Replace the code chamber plate carefully with the 4 red screws.
7. Check the operation of the new code, and make a written note of it before re-installing the lock.
8. Note: Fit either the Blue or Red tipped spindle to the code side, dependant on hand of door.
9. Fit the butterfly spindle to the inside lever handle.
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.
