Carbon Monoxide Detector went crazy this morning?

Mynameis

I have a new Kidde NightHawke Carbon Monoxide detector. We got it about a month ago and it has worked just fine. I live in Ohio and we are in the midst of a winter storm so we have had 5-7 inches of snow and the temp is around 5 right now. This morning as I was leaving I glanced at the CM detector as I always do and it was rising from 30 to 33 to 36. Now normally it sits at zero. I woke my husband and let him know as I left and called our furnace tech. It never went higher than 36 and eventually went back down to 0. We have gas heat, water tank is gas. Nothing else is gas in the house. We were running an a small electrical heater in the laundry room to keep the pipes from freezing, could that have caused this? What else would cause this?
The reason this concerns me so much is we have a 19 month old.

Answer
That is Dangerous.

I would keep an eye on it. If the detector is near a furnace vent I would check the detector when the furnace first comes on. Sometimes with a cracked heat exchanger it will build up some CO when heating before the blower fan comes on. That will give a rise on the reading at the start and then it goes back down as the air mixes in the house.

If you get more readings on the detector, you definitely need the furnace and water heater checked.

what causes Carbon monoxide detectors to go off?

flowerlegz

mine is going off reading a number 47
so i unplugged it then reset it
its a kidde copp 3 model
its back to 0 but i just want to know what would set it off? i have a gas fire place
what in the HOUSE CAUSES IT what can be wrong ?? fireplace? furnace? smoking? fridge/ washer/dryer? all above were not on excpet gas fire place and a smoker in the room

Answer
Do not use your gas fire until it has been checked by an engineer,carbon monoxide detectors can detect monoxide very efficiently,it only takes 0.02 of monoxide to kill you ,don`t want to alarm you but please get the fire checked at once

My Kidde hardwired smoke detector keeps beeping, what should I do?

kidde carbon monoxide detectors image

Q. My Kidde hardwired smoke and carbon monoxide detector just recently has started chirping/beeping every minute or so. I have done extensive research, and I'm not getting any answers that are applicable.

I replaced the battery several times, and the beeping continued. The detector was installed last year, so is not too old, and I even flicked the breaker switch on and off... Nothing works.

Please help me out here.

Answer
These units are problematic. You probably should just replace it. At least you will have some peace of mind.

What can I do about a smoke detector than uses batteries very frequently.?

Both ULI and Kidde detectors installed in my house seem to be eating batteries . The ULI detector was manufactured in 2009. The Kidde one in 2010. ULI says it is warranted for 5 years, Kidde for 10 years. Kidde one has suddenly been false alarming carbon monoxide detected when hard wired. Could the hard wiring need to be replaced? My house was built in 1986. Detectors have been replaced several times over the years. The combo carbon monoxide/smoke detectors seem to have more false alarms and are eating up 9 V back up batteries. Help!

Answer
If the voltage is wrong it could be killing the alarms and they are constantly on the battery hence the reason they seem to go through batteries and false alarm.

You could have AC detectors and your home smoke detector circuit is DC (not good).

You could have DC detectors and the power on the line is AC(not good).

Or the voltage could be wrong it may be 120v ac and the detectors are 24vac. (not good)

Sounds to me like it is time to break out the volt meter and do some sleuthing and them go get the right detectors or rewire the detector power circuit in your home.

Does anyone own a KIDDE smoke or carbon monoxide detector?

I installed fresh batteries twice in both detectors & they are still going off intermittently. Coincidentally-both detectors did this on the same night. Any answers?

Answer
Check the build date on each unit. If they are more than 5 years old they need to be replaced. These detectors do not last forever.

Kidde Smoke and Carbon Monoxide Alarm failure?

I have a Kidde Combo Smoke Alarm amd Carbon Monoxide Detector. Last night it was beeping every minute or so. I took batteries out tested for 1.18 volts , they're low. I put in brand new Energizer Max A A's each measure 1.57 volts digital meter. They were new out of the Wal Mart package. Still beeps once a minute. I double checked position/ polarity , they still beep once per minute?

Answer
most likely you need to press (or press and hold) the 'test' button.
