Thank you folks for bringing these to my attention!
I have a mid-70's home where I don't trust the smoke detectors (only one on each level, nothing in the bedrooms). The one on the main level has been known to go off if somebody is showering (it's located just outside the bathroom, of course :roll: ) ... but didn't go off when I burned up a fry pan in the kitchen and the level was filled with visible smoke!
I could theoretically use the hardwired model (with 'transmitter') at that location and make the rest of the house safer with the wireless ones.
Since there's no wiring changes involved ... I don't have to add AFCI ... correct?
(I'd be surprised to find an AFCI breaker for the panel that's in the basement!)
The other option is to leave it all as is and just move! (Moving next summer is actually the plan!)
