So, there I am minding my own business...

So, there I am minding my own business sleeping away nice and content when the smoke detectors go off. They're all wired together so if one goes off they all will. My wife and I were up and off like shot to the boys rooms to get them out of the house but we don't smell see anything. The detectors stay on for about 30 seconds and then shut off. The yellow light isn't on (that's what has always shown when they go off for a legitimate problem). I looked around for 20-30 minutes, checked the attic, outside etc. No fire and no smoke. We went back to bed and slept for another couple of hours with no issues. I'm not sure WTF happened. I'm going to change all the batteries tonight. I'm a little late but not bad. Anything else I should check?

Sure scared the Dejesus out of me.

Are they dual purpose? Smoke and CO2?

that's what i'm thinking maybe your detector picked up a trace of CO2 ,are they located near a furnace or ???

never hurts to have a drill like that from time to time

Are you suggesting a device that monitors the atmosphere around you failed?

O2 sensor

i've got a fire/CO2 alarm near my Bathroom and water heater closet and it will go off periodically but just chirps

This intro casts some suspicion of doubt upon the rest of the story.



I once had a small spider crawl into a smoke detector and set it (all of them) off.

I took the cover off and cleaned the dust and webs (and the spider) out and never had a problem afterwards.

I would sure hope the detectors didn't go off from CO2, an inert gas that we exhale with every breath (they would be going off a lot lol). Now if they detected CO, a harmful gas that has no odor and can kill people silently in their sleep, then I would be worried.

Was the spider smoking?
You fart snowflakes, and you have a smoking spider. I bet it's a hoot being around your house, lol.

My Brother had a similar problem. He build a new house, and code required all his detectors be wired together, and in addition, they had to have 120v + battery power. Within the first 3 years, every detector in the house failed one by one and had to be replaced. The bad part was that every failure caused them all to scream out a false alarm.
