About CL4000

The CL4000 heavy duty digital Codelock provides 80 User Code, 10 Single-Use User Codes and Code Free. The 2024 model has been updated to have 8 digit Master and Sub-Master Codes.

The CL2000 and CL4000 locks have an 11 button keypad including the badge bar  which acts as the #  button.

The Basics

Master Code

The factory set Master Code is #12345678. This should be changed immediately after installation - see First Use. The Master Code (and Sub-Master Code if set) always start with the # button. This puts the lock into Programming Mode.

Programming

Each programming sequence starts with the #Master Code or #Sub-Master Code. The singular • blue dots throughout the sequence represent an acceptance flash; the keypad will illuminate blue to confirm a correct input. At the end of a sequence, the keypad will flash twice • • confirming it’s complete and programming has been successful. 

When in Programming Mode, a Program Code must be entered within 5 seconds, otherwise the Red LED will flash and beep and the lock will revert to normal. If a programming mistake is made, wait 5 seconds, the Red LED will flash and beep and the lock will revert to normal.

Re-Lock Delay

The default re-lock delay is 4 seconds. This may be changed using Program 06 up to 30 seconds.

Access Methods

1. The lock memory will store 80 different User Codes, each identified by a User Code ID - 01 to 80.
2. The lock can store an additional 10 One-Time User Codes. Each One-Time User Code is identified by a One-Time User Code ID - 81 to 90.
   

Keypad

The lock has a 12 button keypad which includes * and # buttons. The # button is only used for programming.

Code Free Mode

Using the Master or the Sub-Master Code, programs 08 and 09 will put the lock into, and out of, Code Free Mode. In Code Free Mode battery power is not being used. If Master and Sub-Master Codes cannot be issued for this purpose it is possible to use the Key-in-Lever to put the lock into Code Free Mode. This requires changing the cylinder tailpiece according to the CL4000 Tailpiece Instructions.

Locked/Unlocked Status

Using Program 15 the Blue and Red LED’s can be programmed to indicate locked and unlocked status.

Remote Release

REM 1 is intended for use when there is a need to allow a visitor to open the door after having been identified by intercom or by sight from within. REM 1  would be connected to a pushbutton on a reception desk, or to the appropriate button on an intercom. Pushing the button would cause the Blue LED to light and would release the lock for the normal set time.

REM 2 is intended for use when there is a need for the door to be released by an alarm system, such as a fire alarm. This enables emergency personnel to rapidly check that no one is trapped/overlooked in classrooms, wards, guest rooms, etc. during an emergency evacuation, or during a fire drill. When activated by an alarm REM 2  will maintain the unlocked condition for 30 minutes. During this time the red LED will flash once every second and beep to indicate the unlocked condition. The lock will automatically revert to normal after 30 minutes. If required Program 11 can be used to revert the lock to normal before the 30 minute period has finished.
