That was just a comment on my part, not a suggestion of any kind. What would you suggest beyond what I've already done (smoke detector in every bedroom, every hallway, and common living areas)?

I wouldn't rule out a "parent voice" smoke detector. I'd be skeptical of additional benefit from them them without further research into their effectiveness, but I wouldn't rule them out at this point. I don't think I put my kids at greater than normal risk by installing many detectors, teaching everybody how to get out on their own, but also acknowledging the fact that you'd do your best to make sure the rest of your family was accounted for before you exited yourself.

I don't quite get where you're going talking about my "thinking". Sorry if I'm missing your point.
