The AMC2 4W can also detect the wiring conditions ‘short cir- cuit’ and ‘broken’ and initiate an alarm if the appropriate devices are connected.
1. Door open:RS + RP
2. Door closed:RS
3. Broken wire:RS + RP =
4. Short circuit:RS + RP = 0
The resistor values can vary and depend on the used lock system (wire resistance negligible).
The AMC2 4W package includes 2,2 kΩ resistors using for reserves for the RS and the RP resistor.
