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
S
and R
P
resistors.
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.

) no higher than 5K6 in order to obtain clear
measurements.
