The system can be extended by connecting additional sensors (glass breakage sensor, tilt sensor).

Central locking

Unlike the previous systems, a two-motor lock is used here.

locked motor safe motor

The locked motor switches the central locking system from unlocked to locked or vice versa.

The safe motor switches the central locking system from locked to safe or vice versa.

The central locking system provides for three different locking conditions:

Action 1: If the lock is activated once, the so-called "Safe locking - door secured"

The doors can be opened only with the key, but not with the inside door handles.
