Oh wow, this is great information! Thank you for spending the time to do this testing!
I was going to trigger the CO alarm by putting it in a ziplock bag, and then fill the ziplock bag with automotive exhaust analyzer calibration gas, but I can’t find my bottle of calibration gas, it must be in my storage unit. I’ll look again tonight though.
Anyway, this is exciting news. Thanks again for all the time you’ve spent looking into this!
