I’m finishing up the basement and pursuant to code, I need combo smoke and CO2 detectors. They need to be hardwired too.

Thanks!

I have had Kiddie combo units in my rental property for about 10 years. I had no problems other than batteries beeping. I have one located so high I need to pull out my long extension ladder to change the battery. This time I put in an AC powered unit with a 10 year battery so I hopefully won't have to change it again for at lest 7-8 years. I just replaced them all at 8 years. The combo units beeped constantly due to end of life so i replaced all 7 of them.

I have Kidde FireX units in my house and have had no problems with them....they do make a combo smoke/CO detection. Typical CO detectors alarm at 50 ppm for residential which is a safe buffer to avoid nuisance alarms.

I've installed thousands of these with no issues. They have a newer replacement with 10 year sealed lithium battery now, installed a lot less of those, but have had some call backs. Manufacture guarantees either product for ten years. The first gen or two of the lithium ones were complete junk.

I put these in my house

I bought mine at home depot. The first couple I bought were defective from the same batch.

I exchanged them and they have been working fine

I work in public housing..we use these in our units.

Those are decent, I've seen maybe slightly more failures with those vs the Kidde ones, but the Kidde by far outweighs the BRK in usage.

CO2 detector? I think you mean CO (carbon monoxide).

I swing both ways mono or dio.
