Troubleshooting opinion

Per my recent posts about rerunning my smoke detector wiring and adding 2 more detectors, I reset my system and reloaded the settings which cleared the telco seize issue as I expected.

However, after I did this I had fire trouble messages. The Elk is reporting 0.6 for the zone. I now have 7 System Sensor 2WTAB detectors on zone 16. The last is terminated with the required eol resistor. I measured the output terminals and the four or so detectors I checked (first ones in the chain) showed 0.6-0.4.

The two new detectors are the first ones in the chain now. I reviewed the wiring and it does not look like I mixed up the cables since the first three detectors are on different floors.

My thought to troubleshoot this was to remove the resistor from the last detector and then terminate the first detector and test, if it does not work, replace the wire and retest, if it does, repeat and go onto the next detector.

My question is, is this an appropriate way to test this? I won't be able to do this until tomorrow as the last detector is blocked by furniture in the doorway (side note, but would you believe there are furniture specialists who come in to take apart pieces of couches and related furniture so they can be put into a room and then put it back together?).

I'm assuming I missed something basic but any troubleshooting practices that might help would be appreciated. Perhaps my assumption on the wiring issue was incorrect, as now I am consistently getting the issue that was intermittent before.

As an update, this actually worked perfectly. I was able to isolate the issue to a particular leg and will be correcting it tomorrow.

As luck would have it, it was the last leg I tested as well.

On a side note, I think I may be coming up on or already achieved the title of 'most time spent on smoke detectors'...

Strange.........that always happens to me also......finding something in the last place I look.
