In the 95T readers the resistor is placed on the CPU board and can be connected / disconnected by the jumper J1.
In the 90T RKP Card readers the resistor is placed on the small interface board on the back plate. In the GPI -
interface it is placed on the main board. See lay-out drawings.
In each card reader it is possible to install a local separate S-ART bus with maximum 15 S-ART's.
This bus
must not be connected together with other S-ART busses coming from other readers or THOR
intrusion.
The Card reader S-ART bus is used to connect the door contact, electric striking plate, exit push
button etc. to the reader.
