The resistor values can vary and depend on the used lock
system.
The extension package includes 2,2 kΩ resistors which can be
used to replace R

To detect the four states, the voltage drop in the connecting
cable may not exceed special values. The following table shows
the maximum values of permissible cable resistance depending
on the used resistor combination.
