Reviewer: ronald zeuske
i was hoping for a plug in model, i guess this will work anyway.
First Alert does also provide a plug in model for a basic battery operated CO Alarm. The CO600 linked below operates via standard outlet.

I would really love to be able to use your CO2 detector, but I can find no place in my small house that fits the criteria of not near a heat source, window, air return, not in the sun, etc. Where does one put this thing?
