Carbon Monoxide detector went off?

delia

My CO detector went off, but the voice said 0 PPM. It's only a month old. On the ceiling in the finished basement. It's not near any lights. It's in a separate room as the furnace.
Should I be concerned?

Add info: I bought it because a very old one I had in that spot went off. I called 911, the firemen closed the windows (I opened them when it went off) turned up the thermostats; said they couldn't find any readings and told me to buy a new one.

The CO detector is up again and hasn't gone off again. Should I call 911?
Thank you for your responses STEVEN F and adam/penny. I will look for someone to come out and test. It was weird it went off the one time saying go to fresh air 0 PPM, but for no reason. And 0 PPM is nothing, so that's why I came here to ask.
When the firemen came that day they went right up to the running furnace and got nothing. I don't know where else the problem could come from.

Anyway, thank you again. You are both very helpful.

Answer
most of us don't realize it but those detectors come in different co2 detection modes..
i had a similar problem with a new one i bought that went off frequently and after having service people come out to the house they were unable to detect anything wrong. however they said the detector i had purchased was set too low and that's why it went off.
that one cost me over $100.00 for the guys to come out and check.

how can i test carbon monoxide levels in my house?
