I have a First Alert CO614 carbon monoxide alarm that has been getting triggered sporadically when I transmit on 80 meters.   At first this was just a nuisance, but now the alarm has gone into permanent "error" status according to the display.   The manual says that "error" status means "malfunction - replace alarm".   I called First Alert and they took a "report", but I don't know if they'll actually do anything to make the newer CO detectors more RF-resistant.  (I bought the alarm at Costco, so they'll give me a refund with no problem.) 

Anyone else seen this behaviour with CO alarms, particularly the First Alert CO614?   Anyone else have a CO alarm that appears to be RF-immune?

We have a similar First Alert model that gets tripped into "error" mode when I occasionally key up on 2 meters with only 5 watts. Starts the error "chirp" and continues until I take the battery out. Running 1w to hit repeaters seems to help and using UHF/HF doesn't seem to effect it.

You aren't alone my friend!

EDIT: I should add that 80m may trip mine as well but I do not operate enough on that band to say.

.....yep, same thing here.  Unplugged, removed battery and threw the whole thing in the trash.  Bye bye.

Original post didn't state if the CO detector operates on 120vac or battery.  I had a similar situation with a detector that plugged into 120vac and I set it off when operating 160m.  Replaced with a battery powered unit....problem solved.

CO614 operates on 120 VAC and has battery backup.   Replaced unit with a battery powered unit and problem is solved.
