CL4520 Mortice Lock

  • Higher level of control
  • Lock out code users with key


The CL4520 includes a euro profile mortice sash lock with deadbolt and latchbolt safety feature. The new smart lock makes access control easier, offering flexibility and convenience by providing a range of entry methods including the use of pushbutton code, smart card or smartphone, enabling users to choose the most suitable access method. It utilises wireless technology to give building managers the ability to program locks via a Bluetooth™ compatible smartphone by downloading the K3 Connect App*.  Program locks via your smartphone, generate and send codes for easy access, issue smart cards for alternative entry, track and control with audit trail.

Code. Card. Phone.

The smart lock supports up to 350 users, with 100 client user codes, 100 phone clients and 150 client smart cards as an alternative entry option. By installing the K3 Connect App* on a smartphone all aspects of the lock can be managed conveniently, from updating basic settings to creating multiple individual access periods.

Entry can be tightly controlled and monitored by issuing a NetCode®, which is generated and sent via email and SMS. The codes can be created with a specific start date and time that automatically expire after a set duration. The ability to offer keyless entry removes the hassle of storing, issuing, and replacing keys. Audit trails allow building managers to keep track of when and where the lock was accessed. The full lock audit trail data can be downloaded and viewed at any time.

The CL4520 can also be set in code-free mode at fixed times of the day, for example when access is required for cleaning, maintenance or deliveries. This removes the need for a key to manually unlock doors. Up to 10 different code-free periods can be created, that automatically enable when scheduled.

The lock outside lever and key functions as CL4510. The lockcase key retracts the latchbolt for entry without using a code or card. The key controls the deadbolt position. The deadbolt denies access by code and card, when projected, safety features allow the inside lever handle to retract the deadbolt and latchbolt preventing accidental lock in. The key can be used to open doors for management functions such as security and cleaning.

Controlling locks is now even more convenient with the CL4520.
