Smoke alarms sold on Amazon Canada recalled over potential risk

Health Canada has issued a recall for smoke detectors sold on Amazon that they say could fail in…

Might I take this opportunity to note that RIGHT NOW, at THIS VERY MOMENT, Artemis 2 is having problems with a

SPURIOUS SMOKE DETECTOR ALERT

and they aren't seeing why _either_?

MY HOUSE IS LIKE A FUCKEN SPACESHIP

#SmokeDetectors #electronics

AND rf chokes on every wire going to every smoke detector

yes including neutral

WILL IT STOP?

idek lol

hope so

#SmokeDetectors

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 can recycle it cleanly.)

#SmokeDetectors

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 deal with this is to RMA individual units that trigger randomly one at a time until you end up with a set that doesn't. And I guess that's what I'm gonna do, but

holy shit, team

holy shit

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 fucking reason, and then pass self-test just fine afterwards."

And no, regular cleaning - even weekly cleaning - does not help. I do _all the things_. None of it stops the problem.

(4/?)

#electronics #SmokeDetectors #why

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 signal backbone.

But they don't. There's always a unit claiming to be the active detector and it's always smoke (and there is *never* actually smoke), and none of them shut up until we shut off that unit, which sometimes seems to require removing it from power.

So today's afternoon check was basically just another way of confirming what we already knew, and I guess I've done that now, but...

#electronics #SmokeDetectors #why

Checking for DC on the signal line, I get functionally nothing. 20ma DC at most, and even that's something I'm picking up out of noise floor shift rather than direct measurement.

My _thought_ was that if the signal line was somehow floating in whole number volts (for whatever reason) than maybe somehow the right RF noise could kick it over.

The problem with _that_ is that I can now _also_ confirm that non-detecting units go off _exactly as long_ as a detecting device keeps saying it's detecting by putting voltage on the signal line. If that voltage goes away, so do the satellite alarms - and immediately.

And that's not what happens. We have to manually intervene and shut the alarms off ourselves.

(2/n)

#electronics #SmokeDetectors #why

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.

Most importantly, it's not like... 500mv. Or AC. Or complicated. It's simple DC.

When acting as a non-reporting _satellite_ node, it triggers when _receiving_ 4V DC on the signal pin (4.0 exactly), and that voltage is polarity sensitive. -4V doesn't trigger the alarm.

what even are smoke detectors

honestly

what even the fuck are they at this point

change sets change types change brands clean them fucking _weekly_ doesn't matter:

false alarms in the middle of the night

these new ones were extra expensive because i wanted ones that would tell which set them off (because they're hardwire networked, one goes off they all go off) and once again one claims responsibility saying "yep I sure did it it was me I saw smoke"

there was no smoke

why

#SmokeDetectors #FirstAlert #ThisTimeAnyway

okay so I guess there are literally no good smoke detectors anymore? or is it just hardwired ones that are all fucking garbage?

I really thought I'd finally found it, I really thought I'd found why the smoke detectors liked to go off for fun at random times, more memorably at night, most memorably around 1-3am, when I found that long-term defective connector but

GUESS NOT

"Anything to declare?" "Yeah, don't buy Kidde."

seriously, fuck kidde.

We're ditching all of 'em. every single one. fuck 'em. DO NOT BUY KIDDE, they don't even honour warranties.

Trying BRK this time, they're the same people as First Alert, but it's the contractor brand. Combo smoke/CO detectors. They're more expensive. Hopefully they'll also be better.

FUCK kidde.

Okay, one of my 10 #smokedetectors started its low #battery alarm tonight. They always start beeping during the night, don't they?.

Should I continue to buy cheap 9V blocks at the local discounter or switch to rechargeable batteries instead (edit: for the environment)?

Non-rechargeable: Duracell industrial (1,35€) lasted 3½ years. Cheap batteries (50 Cents) lasted 2 years.

The rechargeable ones (~5€) do seem to provide just 8,4V and store only ~300-650mAh. Charging via USB cable or proprietary charger. I'm afraid they don't last more than a year and replacing them frequently is tedious.

Do you have experience with that?

Hey, did you know #SmokeDetectors only last 10 years? Check the manufacture date on yours—it’s on a sticker by the battery compartment.

Does anyone know why a bunch of networked #smokeDetectors would go off when there’s no #smoke, fire, or #carbonMonoxide?

My house is pretty humid. Could that be a factor?
I’ve tried vacuuming the detectors based on the theory that it might be dust inside the detector. That doesn’t seem to have done much.

Please let me know if you have a clue because this is super annoying
