Visual Difference, Smoke/CO2/Combo ?

Visited Home Depot to distinguish between smoke detectors and CO2 detectors, but photos are too large to upload. I found CO2 detectors, smoke detectors for the bedroom, smoke detectors for the kitchen, and combo smoke/CO2 detectors. Other than the rectangular CO2 detector, all of the others look EXACTLY ALIKE with no distinguishing mark; and the Home Depot in-store-expert advised me that one needs to look inside the devices to determine the color of the built-in battery. Any advice otherwise?

p.s. Is the peer appraisal community (for lack of another description) concerned when the install date isn't penciled in?

I have said more than once there is a detector installed wherever, but I cannot tell if is is smoke, CO, or both.
It has not come back to haunt me. Yet.
Halloween draws near though. :leeann2:

CO2 is actually carbon dioxide not carbon monoxide, this I learned as an underwriter pointed this out to me on my appraisal, so I now painfully write out carbon monoxide detector every time when referencing carbon monoxide detectors.
So anyway many of the units are now combination smoke and carbon monoxide detectors. All sort of different sizes and shapes but one difference that seems to be consistent in the typical round ones I see is that there are vents on the face of the units in a small grill like design. When they have just one set of vents it is smoke detection, Two sets of vents indicates it is a combination unit.
When you cant read them as they may be on ceiling, take a picture then blow it up and see if its readable.

Sounds like you need to take up smoking. I suggest cigars for the extra available volume of smoke. Toke on it and blow on the detector. If it goes off, its a smoke detector. If it doesn't, its a CO detector or a non functioning smoke detector...Never mind.
