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.

Worried about Carbon Monoxide.?







Worried about Carbon Monoxide.

Okay so the carbon manoxide dector went off. It was showing there was 400ppm, after it stopped beeping for a few min. I checked the memory, and it said the max ppm was 0ppm. I replaced the batteries since I thought it could be the batteries could have gone bacd. But when I checked the amount of juice left in the batteries it was still pretty much fully charged. So I put the new batteries in and it's been about 2 days ago and the detector hasn't gone off since. So was it was just a false alarm? It's not even showing a reading above 0 ppm.

Sadly there's no way to get it checked out or my parents will get pissed at me...



Answer
Carbon Monoxide levels could have risen temporarily and then fallen back to 0 ppm. I cannot see any other explanation. Notify your parents that the alarm went off and they can either replace it or get it checked out by a professional.
