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.

Installation manual
1. Door open: R
2. Door closed: R
3. Open wire: R
4. Short circuit: R
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 RS and RP
resistor.
