Available in one PVD finish
Stainless Steel (SS)
CL500 PK stainless steel lock available with either lever or knob handle.
This is an example of what a panic pad looks like; we provide the keypad plate only, supplied with an extra long spindle to work with most exit devices with 8mm square followers.
The CL500 PK coded plates are supplied with a random code commencing with the ‘C’ clear button. To change the code after fitting, the lock must first be removed from the door. The code is non sequential, that is the code can be entered in any order e.g. 1234 can be 4321 or 1342 or whatever is the most convenient sequence. With the 11 buttons a total of 2,047 different codes are available, any of which may be entered in any order.

Check operation of the coded front plateTurn 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 2,047 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.
The CL500 model is intended to replace the conventional door furniture fitted to an existing mortise latch, or an existing mortise lock which has both a spring latch and a deadbolt. The square follower should be 8mm square. Any lock and key mechanism is retained to operate the deadbolt. The latchbolt will only operate by code, and not by key.
A mortise lock case should have holes for fixing bolts to pass through on either side of the square latch follower and sometimes, additionally, a hole below the follower. See figure 1 and confirm that your lockcase is compatible with the CL500 lock plates.
1. Hold the black neoprene seal with the three holes against the door, perfectly vertically, with the rectangular hole centrally over the follower. Mark the top and bottom holes on the door face, and repeat the procedure on the other side of the door. Remove the lock. At both points drill a 12mm hole through the door. Drill from both sides for greater accuracy and to avoid splintering out of the door face. Check that the existing spindle hole is at least 18mm diameter. Replace the lock.
4. Take the adaptor kit, item 10. on the contents table. Cut the tow M5 countersunk head bolts to length to suit the door thickness; i.e. door thickness plus a maximum of 10mm (no more than 5mm should enter the front plate). Hold the front plate, with the three hole neoprene seal, against the door over the protruding spindle. From the other side of the door, fix the adaptor plate to the front plate using the two M5 countersunk bolts. Before tightening up the fixings, make sure that the spindle hole is centrally positioned over the follower. Do not use excessive force.
5. Cut one of the long black socket head screws 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 front plate. Place the neoprene gasket over the adaptor plate. Use the screw with the ‘T’ shaped Allen key, to fix the back plate to the front plate through the TOP hole. Using the 20mm socket head screw fix the back plate through the BOTTOM hole to the adaptor plate. Do not use excessive force.
6. Before closing the door, enter the code and check that the latchbolt retracts when the lever handle is depressed. Now check the operation of the inside lever handle. If there is any binding of the handles or latch then loosen the top and bottom bolts and reposition the plates slightly until the correct position is found, and then re-tighten the bolts.
1. Hold the black neoprene seal with the three holes against the door, perfectly vertically, with the rectangular hole centrally over the follower. Mark the top hole and the holes on either side of the follower, if not already drilled, then repeat the procedure on the other side of the door. Mark an extra hole on the inside of the door in line with the bottom fixing hole. Remove the lock. Drill the 3 x 12mm holes from both sides for greater accuracy, and to avoid splintering out of the door face. Check that the existing spindle hole is at least 18mm. Drill the extra 12mm hole 5mm deep on the inside of the door to accept the fixing nut on the adaptor plate. Replace the lock.
|3. 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.
4. Cut two of the black socket head screws 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.
5. Apply the front and back plates, with the neoprene seals in position, against the door, over the protruding ends of the spindle.
6. 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.
7. Before closing the door, enter the code and ensure 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 latch then loosen the bolts slightly and reposition the plates slightly until the correct position is found, and then re-tighten the bolts.
The CL500 code chamber consist of 11 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 CL500 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 11 buttons, a total of 2,047 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 1584.
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
1. Take your CL500 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 coloured.
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 coloured 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.
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.
