The Ei3016 Optical Smoke Alarm is best for detecting slow, smouldering fires in the home in the living room, bedroom, hallway, landing, or dining room.

This type. Never had issues with these so why do you think they are frowned upon

No, I'm not talking about that. I use those, but they are mains-powered with lithium-ion battery back-up.

The ones which I said are 'frowned upon' (even though I would personally be comfortable with them) are powered only by a non-rechargeable (and not replaceable) lithium battery with an alleged 10-year in-service life - such as the Aico Ei650i

Maybe they are (I have no personal experience).

However, that's got absolutely nothing to do with the question I posed when I started this thread, nor even any of the subsequent off-shoots of the discussion!
