Most do not do both, but you can certainly buy those that do. If all yours are the same/match, it is likely that they are not as the ones that do both are usually more expensive and people usually do not send the extra money. Just google the part number off of one and the specs will tell you. I have one in each level of my home as there is a gas log in each...but the rest of the detectors are just for smoke/fire. Mine are mounted low upstairs but on the ceiling downstairs.

I bought all new detectors for my vacation home when I bought it (they are only good for 10-12 years...some less). I used the combination CO/fire ones throughout as I was able to get a good deal due to volume (hardware stores sell builder packs) and i liked that they all matched and operated the same, mounted the same, used the same batteries, etc. I chose not to use them for my monitored alarms (just regular smoke/fire detectors, as it is really only an issue when you are there...and they are reportedly more prone to false alarms.
