If the detectors are AC-powered, it does sound as though it could be a bad connection resulting in low-voltage when the load of the iron is connected.

Trying the iron in other outlets might narrow down the problem.

Going back next week for more thorough investigation.

Were the smokes operational before the iron was plugged in? Perhaps the smokes are connected in series. As he iron heats up, the resistance (and freqency of the smokes beeping changes)

Awesome forum!
