I am 59 years old and have changed maybe a dozen smoke detector batteries in my life. Every single one of them has been in the middle of the night, including 4am last night. Is this universal, or is it a fucking conspiracy?

Well, the good news is that _unlike_ the makers of the previous smoke detectors we've had who refused to honour their warranties, BRK/FirstAlert gave absolutely no pushback on this. They don't even want the original unit mailed back, they told me I could just toss it out.
(Since it's optical, I […]
this is the opposite of fire safety
this is the opposite of how anything like this should ever work, I mean
what if all the RMAs are getting you are a set that won't go off even when they should?
but whelp
guess i'm gonna find out
'cause this sure ain't workin'.

If you're new to this adventure, I have heard this exact same story from _many other people_ at this point - though nobody I've talked to has said they've literally taken metres to the signal wires to verify that way.
Regardless, I know it is not just us.
What I've been told from others who […]
All _that_ does is get us right back to where we started, which is, "we have alarm after alarm after alarm of different makes, methods (ionisation, photodetector), and models which just in this house are determined to go off randomly, usually but not always at night, for absolutely no detectable […]
The reason I paid meaningfully more than baseline for this particular set is that they report exactly which detector went off and why. That way, if it were the signal line somehow triggering the alarms, none of them would claim to be the originating unit; they'd all report it came from the […]
Checking for DC on the signal line, I get functionally nothing. 20 milliamps DC at most, and even that is something I'm picking up out of noise floor centre shift rather than direct measurement.
My _thought_ was that if the signal line was somehow floating in whole number volts (for whatever […]
Okay so let's write this down to think it though.
The latest smoke detector to howl pointlessly into the night sends out 11.3V DC onto the signal pin when triggered but running off batteries. I suspect that's 12V nominal, and it probably delivers 12V when operating on AC power.
Not super […]
When did you last change the batteries in your smoke detector?
Smoke detector batteries should be replaced every six months, and the entire unit should be replaced after ten years. Don't wait until you hear that dreaded chirping!
