Home built in 2005. These are interconnected Fireex smoke detectors (I
believe because they have a yellow wire connected to the red wire). All the
breakers are marked, but I don't see one for the smoke alarms.

Now I was away on business and my wife had an alarm chirping and couldn't
get it to stop so she literally in wired it while it was hot! Could have
killed herself.

Problem is I want to rewire it and I don't know how to cut the power to it
since there is no breaker.

Thoughts?

Oh boy you are real nerd
