| Since yesterday, every few minutes, the smoke alarms go off and beep several times, then go quiet again. I took the batteries out and tested them with a multimeter. All above 9 volts. They are also hard wired to electric. We can't find any reason for them to be beeping.
Anyone here got any ideas about it? Pooh Bear |

| Could be flawed electronics. Can you get the manufacturer name and contact them? It could be that the number of beeps and beep type (long, short, etc.) may tell you the issue with the unit. |

| I think this is the one we have. It is less than 6 months old. Kidde AC-Hard-Wired 120-Volt Smoke Detector We have two of them interconnected. One is in the They didn't go off much last night. But started early Pooh Bear |

| So the beeps happen at both alarms at the same time and beep the same?? How far apart are they?? |

| Distance wise they are about 6 feet apart, maybe a tad more. One is in the garage and one is in the laundry/mudroom. They are separated by a steel door (exterior type). Both are ceiling mounted. |

| In order to isolate the detector at fault, disconnect the interconnect (the red wire) from one of the alarms. Then, only the detector at fault will beep. Did the multimeter you used to check the battery have a "battery test function" for testing 1.5 and 9 volt batteries? Reading the voltage on just the DC volt scale doesn't place a load on the battery and can give a false good reading. Also, cold weather, like in an unheated, uninsulated garage, will cause a drop in battery voltage. |

| I have had detectors in cold areas (like unheated garages) act very different than their brethren installed in heated spaces. For testing purposes, I'd disconnect the garage detector and see what the inside detector does. Also "So the beeps happen at both alarms at the same time and beep the same??" |

| Smoke detectors in a garage are generally a bad idea - if you're parking a vehicle in there, the products of combustion are going to trigger it every time. Since it's unheated, that could be an issue too. I personally think some sort of fire detection in a garage is a great idea, but it needs to be a heat detector, preferably a rate-of-rise detector which means you need a burglar alarm (or dedicated fire panel) to connect it to. Even sawdust might set a smokie off, although the new ones seem to be very good at distinguishing these days. |

| It's just the one in the laundry/mud room. The one in the garage is not going off. It is going off less and less. It just now beeped once. It beeps a different pattern each time it goes off. My wife took it down and blew on it to get dust out of it. That seems to have helped. It's not going off every 10 minutes now. The instructions say use a vacuum set up to blow air to clean the dust out of it. Probably try that and see if it helps. My VOM only tests voltage on batteries. No load testing ability. |

| Is this a detector that is also a particle detector? If so, lint/dust in the air will set it off. |
|
| You wouldn't happen to have an exhaust duct on your dryer in the laundry room with a slight hole in it?? Could be dust/lint from the discharge hose clogging the detector? I'd clean the crud out of the detector with a wet-dry vacuum, put a box fan in the laundry room blowing/excavating any particles from the room to outside/another room without a detector. |
|
| .... for an hour or so. Then put all back to normal and listen for the beeps. Strange/interesting that the beeping decreased and did more so after cleaning the detector - I think we are on the right path. |

| Could have been drywall dust or even paint overspray if the builders were slack. Dust is a pain for smokies. |
