I can't get any smoke detectors to work on my Elk zone expanders. I ran an 18/4 from my main board's SAUX/VAUX to the 2ndary cabinet for juice, wired everything up, as soon as I enable the zone with a smoke detector, I immediately get a fire alert.
It's a 4-wire smoke detector, so I hooked up to both SAUX and zone.
When I repeat the same steps with the main board, all wires the same, resistor the same, everything is fine.
I tried this with 3 different smoke detectors, so I know it's not any given smoke detector or wiring run.
I'm baffled as to what the problem could be. Any clues as to what to try next?
