I have (6) 4-wire DSC FSA-410 smoke detectors and (1) 4-wire GE 240CO CO2 detector. A single 18g five wire cable was daisy run through all 7 locations and back to the panel during construction because I hadn't considered using a monitored CO2 at the time. I wired them as indicated in the DSC 832 reference, parallel with EOL Relay and Resistor. I used a standard 12v relay from Radio Shack because I couldn't find the part they suggested in the manual and the diagram looked just like a standard relay. As I was installing, it occured to me that it would be more beneficial to have the CO2 on a seperate zone so that if ever reported during an actual problem, the fire department would know ahead of time that they were dealing with CO2 and not to be surprised not to see smoke and nobody answering and just leave. This is where my amateur assumptions may be askew. I figured since I had an extra wire in the cable, I could use the same power and ground, and same common as the smokes by using adjacent zones on the panel which share a common anyway... and use the extra wire for the unique zone signal loop. When I finished all my wiring, and started programming... the instant I assigned the fire zone... it tripped and went into alarm and I had to reset with user code... it didn't do that again. However, I continued to get an open trouble on the CO2 zone. I tried with and without a resistor, and I tried switching from NO terminal to NC terminal on the CO2 detector, but it always showed open. I gave up and wired into the Fire Zone loop and I have no trouble on that zone. So my first question is... is it simply not possible to pull off with only one extra wire? My second question is... although I have no trouble indications for the fire zone... should they all go off and the panel go into fire alarm when I hold down the test button on one of the detectors? Because they don't... and I'm not sure if this is a problem. I appreciate your help and patience with the long thread.

I'm gutting an old farmhouse & there have been some people nosing around, so I'm installing a Vista20P & an Aurora motion detector that will later be used in the finished home. First question is about wiring the motion detector to the panel. I believe I have it right at the sensor. That seemed pretty straight forward, but where do I connect the + & - wires on the panel? Right now I had them attached to terminals 4 & 5 which is what my 6160 keypad is connected to for power. The RR wire I just connected to terminals 8 & 9, which should be zone #1 correct? Do I need to add a resistor to this somewhere? If so, exactly where do I need to connect it. In laymans terms please. This is the first I have ever messed with security systems, so I'm a little green. Next question. I walked through the Data Field Programming last night but it was getting late so I might have screwed something up. I get "Fault 01" & this goes through "Fault 08" & then it says "Check 100 RF Transmitter" I think, can't remeber exactly. I have no RF transmitters & I don't think I programmed it to see one. What do I need to do to fix all these faults? Thanks! Dan
