Why does my Nighthawk carbon monoxide detector keep chirping every so often and reading 248 after I reset it?




Dragonlady


The last few days, the detector has chirped...does it for about an hour or less, every 30 seconds or so. Sometimes it stops for hours..even up to a day before it does it again. I've changed the battery twice. It came up low battery once...but was reading 0 the whole time the other times it happened. Then when I hit reset, it went to 888, then to 248 and once said 247. I don't understand this...makes me worry, yet it goes back to 0.


Answer
It suggests that there most likely is a malfunction if as you say that you've put new batteries in. It could also be an end of life warning (not yours, the carbon monoxide detectors'). If you've had the alarm for between 4-7 years this could be the case. People have had some problems with this particular model of carbon monoxide detector. It's probably best to contact the manufacturer directly, in this case Kidde, and if you have a valid warranty get them to send a new one asap. If not and your detector is in the end of life period it's probably better to buy a new one asap anyway. In the meantime it's better not to take any risks; make sure your house is well ventilated at all times.

Why dose my carbon monoxide detector goes off when there are no CO2 levels present?

For some reason the CO2 alarm keeps going off. I know the stove tops are off, and the 9V battery that powers it, have not gone down to levels that will make the CO2 alarm "chirp" once a minute.

But for the last 2 weeks my CO2 alarm keep going off at all hours of the day or night. Even when I'm not home.

Can someone PLEASE HELP!!!

Thank You in advance.
I checked the date on it, it with was manufactured in December 2004.
The batteries are brand new. They were changed last month.



Answer
Most carbon monoxide detectors use a chemical reaction to measure levels. When they get old they can malfunction. Check the manufacture date on yours and see if it needs replaced. For more info, check out the furnace page at my source. It will give you more info about co sources and what to do.
