Is there any code that specifies a minimum required distance between a
ceiling-mounted smoke detector and a ceiling-mounted CO (carbon
monoxide) detector? My initial thought is that since there are
commercially available combo smoke/CO detectors, installing them next
to each other wouldn't be an issue. However, I wasn't sure if there
was any code or other requirement that applied to the installation of
two discrete units.

Do not be concerned : they won't breed.
