My Carbon Monoxide Beeps Twice after a Reset Before Going to Zero.?

Johnny

I noticed today that my carbon monoxide detector had become a little unplugged from the outlet. I plugged it back in immediately and hit the reset button. The detector's numbers lit up (showing 888) and made no noise. A few moments later it displayed 244 and then 222 and started beeping. It then went back to all numbers lit up and then immediately went to zero and was silent. This whole process took about 1 minutes or so. When this happened I immediately went outside and called someone to ask about this (not the police immediately). They said it probably just happened when you hit the reset button. I was thinking this too and so went back inside and hit the reset button again. It went through the same sequence, eventually ending at 0. So, is it safe inside the house? Is this common or does this occur with anyone else? Any help or input is appreciated. I personally believe it is something that happens every reset. I believe this system is a nighthawk carbon monoxide detector.

Here are a couple of links to answer all your questions about carbon monoxide detectors and what is carbon monoxide.

How old is your detector? Even though it is a plug in, does it also have a battery. Some do.

i've never had anythink like this happen. the detector is a few years old, and all the sudden about 15 minutes ago i heard something beep and then i heard it beep again and realized it was the detector. when i went to see what was going on all it said was "Err." or what obviously means error. why is it doing this and whats going on?!?! never ever have i had the thing go off because of carbon monoxide! and its not showing numbers, i've tried unplugging it and it plugs in and lights up 888 [like it always does] and then goes to Err.

Answer
I would call for assistance immemorially and stay stationed outside of the house.

A family friend of ours had a similar problem.

Call over a neighbor for assistance.
