I have been _plagued_ by smoke alarms that treat a low battery as a sign of a fire. To the point that I am trained by their crying wolf that it is _always_ a false alarm. Particularly when I'm asleep and they've gone off.

I would actually prefer if rules mandated they could only have large capacitors and just NOT CARE if the power goes out.

Next would be to require a sensor pick up an area that's IR hot AND smoke to go off. I'm sick of bathroom steam sometimes setting them off too.

Finally, ONLY FOR EMERGENCY would the loud and annoying cry be allowed. Tests, low battery, anything not indicating a clear and immediate threat to life should be a low noise, low light, indication. Maybe a 2 second low-quality sound clip that says 'bat' at a soft voice volume with a strobe at the end of the voice (when a human would be looking for the noise). Fog/Steam/etc, E.G. possible fire without detected heat but at a weak detection level, could also use the 'info' level of alert, not the DANGER level.

I’m at the point where a low battery in a smoke detector triggering a fire would be an actual upgrade. Have tried cheap, expensive, and multiple models. Currently have zero active and about 8 on a shelf. They randomly go off even with new batteries. My house isn’t on fire.

I have literally never had this problem.

I don't mean that in a "so you must be wrong" way, but "there may be something up with your situation besides the smoke alarms themselves".

Completely agree and it’s very frustrating. My guess is humidity, as hot nights seem to be when they go off.

My guess is the landlord's invariably choose the cheapest models that check the box; or that everything out there just sucks for some reason.
