carbon monoxide / fire alarm detector going off?

Q. i don't know which one it is... one of them keeps going off and whenever someone goes near it it stops. i can't tell which one it is because they are right by one another and there's no sign to see which one it is. i'm scared. help?

p.s. there's no smoke or anything.

Answer
to tell which is going off---take down fire alarm-take out batteries....if alarm stops-it is the fire and probably needs new batteries---but do a real good sniff test around to make sure there is no smoke up where the alarm was...


if the alarm continues-it is the carbon monoxide one--i'd check to see if the thing takes batteries-or is it plugged into the wall--if it is in the wall--get out and call 911, or the fire co direct---if it doesn't--try putting in the battery from the fire alarm....if it still sounds---get out and call fire co.

Why didn't the carbon monoxide detector go off?

Q. We recently had our AC/heating unit replaced. The installer said the old one was leaking carbon monoxide. So why didn't the carbon monoxide detector go off? It was and still is working(the installer tested it).
The installer didn't try to sell us a new one.

Answer
The way gas furnaces work is the blower motor that circulates hot air through the house has a higher static pressure than the combustion blower moter that creates the fire making the heat exchanger get hot. When the heat exchanger goes bad or gets holes in it it can leak carbon monoxide but more likely it will lose pressure from the blower motor air forcing air into the heat exchanger and not into the house. This would cause a roll out event. This is where the flame from the furnace would travel in the wrong direction tripping a safety limit shutting down the furnace. The way furnaces are designed even if they leak carbon monoxide or have holes inb the heat exchanger they will still keep the levels in the house at safe limits.

Why does my carbon monoxide alarm keep going off?

Everytime my mother cooks using the stove, the carbon monoxide detector goes off. It seems like every sunday when she cooks for a long period of time faithfully the detector goes off like an hour after the stove has been shut off. I take it down remove the battery and open the windows. about 20 minutes later i put it back up....no alarm goes off. the battery is new so that shouldnt be an issue. The only thing i am fearing is a possible gas leak. What should i do?

Answer
It could be a couple of things.
How old is the detector? They have a sensor that only lasts so long and they should be replaced every 5 years.
If your mother is cooking with gas is there an exhaust fan that removes the air to the outside of the house? If not it could be caused by the recirculation of the combustion air back into the flames.
A good flame should also be a light blue, if it is a lazy yellow flame then there isn't enough primary air (air that is mixed with the gas before combustion) if that is the case then you should ask someone who knows how to adjust it and they should also check for soot which may be evidence of flame impingement.
Gas, like electricity, it is safe if done properly but can be very dangerous if done wrong and Carbon monoxide is very dangerous and any warnings should not be ignored.

My house carbon monoxide alarm keeps going off?

Angel

It has gone off 3 times this week. Should I be worried? It has been 3 hours since the garage was open.

Answer
Better get it checked by the fire department. When my grandson & I came home a couple years ago I heard my carbon monoxide alarm going off as soon as I parked the car in the driveway. The dispatcher said she would send someone immediately, but in the meantime we were supposed to go outside for our own safety "just in case". It was winter, we'd just had a snowfall, and it was freezing, but at least the car was still warm. When the firemen got there they told my grandson to stay in the car but had me come in to show them where the alarm was. I had already checked the battery before calling, but they took it out again. Even though it was a relatively new battery they replaced it with another. The alarm still kept going off. It was placed on a wall fairly close to the closet where the furnace was. They checked that out thoroughly to make sure there was no leak. Then one guy went through the entire house with a monitor checking each room. Another one inspected my gas stove and my water heater. They couldn't find anything wrong and said it must have been a defective alarm. They suggested I get another one and also have my plumber/electrician come in to reinspect the furnace if the new one went off. They were there almost 2 hrs. but I felt a lot safer when they left. My grandson, however, was frozen from staying in the car.

Better get it checked ASAP--carbon monoxide, as you probably know, is odorless and colorless. You won't know you have a problem unless the alarm goes off. Make sure you're not feeling headachy or lightheaded or just generally not well. Get into the fresh air if you are and use your cell to call the fire dept. It may be an old battery. I was told to change them every time I changed the batteries in my smoke detector.

Why does my carbon monoxide detector keep beeping?

MirandaT

2 days ago my detector started a slow beep every 30 seconds. I has no idea what was going on & turned the heater off & opened the windows. It stopped after about 10mon & I thought I solved the problem. Then yesterday it did it again! I did the same process over & even pushed the test/silence button to make it stop. I called & was told that it was a low battery that needed to be changed, So I went & bought new ones to exchange with the old. Again, I thought I solved the problem. Now, only 8 hours after purchasing new batteries the slow beeping has started up again!! I don't know what to do?? The heater hasn't been on since the first incident yesterday & the windows are still open. What should I do?!

Answer
What I would suggest is to try new batteries, If that fails, then put a different detector in same area and see if it happens with that one. If not, its safe to say you have a faulty detector. However, if it too goes off then there is always a possibility that you have a monoxide problem. Hope this helps.

My carbon monoxide detector keeps beeping?

Emily J

SO, I was wondering, I have a carbon monoxide detector in my basement, we also have one on the main floor, and one upstairs, the one in the basement is beeping, it says 0, so I don't know what is wrong with it, the other ones aren't going off, any ideas why this is? It just beeps every few seconds.
It stopped beeping after I re-set it once.

Answer
If it is just beeping like that, and the indicator says 0, it means the battery is getting low. Change it and it should be fine.

Q. My carbon monoxide detector alarm keeps going off but i don't wanna get the fire department involved if it is nothing...i've tried cleaning it....moving it around the house to different locations and replacing the batteries with new ones...it stays off for 5 min at each new location and then goes off again...I live in a medium sized house, all the window etc are open...the central air hasn't been on since last night...I do smoke but, I'm pretty sure that has nothing to do with it?? cuz i've always smoked....my cats are acting normal as is my bird? what do you think?

Answer
Call the fire department. They won't mind. They would rather come out on a nothing call like that, than pick up dead bodies. I did the same thing and they said it was not a problem.

Why does my Carbon Monoxide detector keep going off?

Stephen T

We have a brand new First Alert smoke/carbon monoxide detector. One day it was going off when I came home for lunch. I called the fire dept. and they came and did a test and said my levels were normal for the basement. A few weeks ago it started going off again so I opened a window. We felt no symptoms. This morning it went off yet again.

Is my device faulty? What could be the problems. Every time it has gone off I have replaced the batteries just in case the signal meant low battery.

Answer
I would try a different unit (or even different brand) and see if the results are the same. You might even try getting separate smoke/CO detectors and try different locations. And if it goes off again, I would have the fire department come and check more than the basement (and they should use two detectors to make sure THEIR readings are accurate). There's a whole myriad of factors involved here; I wouldn't rest until I was sure I wasn't in any danger. People die from CO poisoning every day. I've found a couple of websites that might help:
