I ran my ATV (Motorcycle) in the garage with the doors closed for about 5 minutes or less, and 3 hours later the smoke alarms started going off. My smoke alarms also go off if there's carbon monoxide. Could this be caused by the atv even though it was 3 hours later? I'm trying to find the source and I'm not having much luck. I opened the windows and since then, it hasn't gone off. I don't want to contact the fire department being that it's 3AM on Christmas day...
I plugged in a carbon monoxide detector into the wall, and shortly after about 15 seconds, it started going off as well... .So it wasn't a false reading.
Just to give a safety update, the alarms haven't gone off in about an hour.
Answer
There are smoke detectors, carbon monoxide detectors & combination units. You most likely have all but one, smoke detectors. The other one is a combo unit. The combo units are a bit bigger in size / look different/ have two vs one light on them. You might have ALL combo units (prickly building department).
A detector with a weak battery should be beeping once, every couple / 15-30 minutes.Only the one with the weak battery will beep. It's telling you there is a problem. A weak battery will cause it to malfunction, most likely NOT work. If the light is on, but not beeping , the battery is OK.
If they ALL go off, they are most likely interconnected. This can be checked by testing. Push in the test button on one, wait a few seconds. Every second or two, you should here the next one going off. If they progressively go off, they are interconnected. It's hard, with the one right there going off, but it can be heard that they are progressively going off. Stick the free finger in an ear. Stretch to reach that first one. One going off will cause all to go off. This is to wake you up, before the basement fire gets up stairs.The CO detector is probably picking up some un ventilated CO & causing the alarm. In my area, the Building Inspectors want the CO detector on the upper/ second floor / by the bedrooms. It took some time for the CO to travel to the Co detector, then it went off.
If they go off the next day, it's the furnace / hot water heater / fireplace, bad cooking, etc causing the alarm condition.
Ventilate your home. Open the doors, windows for a bit. Get some fresh air in there. Make it bit cold in there, then close it back up. If you don't get rid of the CO, you will at least dilute down to where it doesn't matter.
Does the plug in unit have a meter reading on it? My experience is, they do. What does it say? Hopefully zero. If it has a number, what does it say for a safe reading? Above zero, doesn't necessary mean bad. If it's sounding / alarming, etc, THAT'S NOT GOOD!
Interconnected CO detectors going off means an UNSAFE condition, not necessarily a DANGEROUS condition. If they went off & you ignored this (how??), for several hours, this would be bad. Going off, then opening doors, then they go silent would be OK, until they go off again.

smoke/carbon monoxide detector?
Rmacy
we got this carbon monoxide detector bout 2 years ago. and works but never went off till now. so i replaced battery. but still beeping. sometimes 2 beeps then like crazy. it doesnt smell like anything. could it be the battery again?
Answer
I have worked with carbon monoxide detectors. And many times when they get 2 to 3 years old they will give a false positive. I recommend that you pick up a new carbon monoxide detector a see if it also says you have a problem.
