I was thinking the same thing with the diode, but I'm not 100% clear on the troubles that the OP is getting. Are you getting both a NAC trouble and a zone trouble?
Btw, here are the resistor values according to the manual.
6.8 kΩ, 1/2W, End-of-Line Resistor Harness for standard IDCs; (ref. 733-886)
3.3 kΩ, 1 W, End-of-Line Resistor Harness for high current IDCs; (ref. 733-893)
10 kΩ, 1/2 W, End-of-Line Resistor Harness for NACs; (ref. 733-894)
2.2 kΩ, 1/2 W, End-of-Line Resistor Harness for 8 Pt I/O input mode; (ref. 733-892)
1.2 kΩ, 1 W, End-of-Line Resistor Harness for N.O. tamper switch monitoring; (ref. 733-891)
Looks like OP needs new IDC resistors if he's using 10K's on the IDC. NAC trouble is probably needing a diode.
