Yes in bedrooms.

Edit: Oh wait, you're specifically asking about the combo part right? THAT I'm not positive about.. far as I understood it, only 1 had to be carbon monoxide.. but all have to be battery backup. I always do combos though.. never pushed it before.

Any update on if we can get away with just 1 or 2 combo units?

Awesome man, thanks for the update.

So theoretically a house with bedrooms all the one level could only require 1 combo unit. Many houses I do will still need 3, but that's better than all 7 being combo.

Tell your old customers there's a recall on those smoke/co units and they need to be replaced ASAP.
Swap them out with regular smokes and save the combos for future homes! :thumbup:

I don't think so.. doing so is just going above and beyond minimum code. It's not a bad idea, but if it's not specified in code rules, then I won't be doing it.

The smokes detect smoke.. the CO's detect CO and the combos just happen to do both in one unit in the same location.
