My smoke detectors all started smoking at the same time after alerting.

    1. I just replaced all my direct-wired smoke detectors with 10-year battery only detectors. I just got tired of the depleted battery chirping every year. Always happened in the middle of the night.

      Ah, a classic mistake, that was your household *smoking* alarm. For all the occasions when a regular alarm isn’t alarming enough!

    3. The electronics version of waking yourself up with your own snoring.

      Perhaps it’s in self test mode.

    4. For context, I’ve lived here for 6 months in this apartment, and the smoke detectors were tested two months ago during an inspection… nothing seemed out of the ordinary until recently.

    5. I’ve seen that happen to smoke detectors when line voltage is applied to the red wire, maybe someone was doing some electrical tinkering in your building and literally smoked your smoke detectors

      Same thing happened to me. Every (hard wired) alarm in the house went off at once. Pulled them all out and just ran them off batteries after that, and it seemed fine. They would go off if I smoked out the kitchen, so they worked. I haven’t trust hard wired alarms ever since.

      I think you may have bought the wrong smoke detectors. I think they may be using smoke to signal that they have detected something.

      When the mains voltage goes through the interlink. Ive seen it happen a couple of times.

    9. From what I can tell, the wire nut seems to be the problem. Call a sparky and have them swap it for a wago. Loose connections tend to have quite charred results, and wire nuts are nothing but loose connections.

    10. Jokes aside, I would guess that there is a wiring fault and you should probably call an electrician
