Carbon monoxide detector went off?

Its 2:30 in the morning and my carbon monoxide detector went off about 20 min ago. It was realllllllly quiet and only barely woke me up, not like the loud obnoxious noise it makes when I've tested it in the past. It sounded like an alarm clock, not really a chirping sort of noise. It only went off for about minute and then stopped and hasn't gone off since. Should I be concerned? My parents just shrugged it off and went back to sleep but I'm not so sure they should have done that...CO2 is nothing to mess around with.

Answer
I've had mine go off before and worried about it, too. If it goes off but eventually turns off, you are fine. Trust me, if that thing detects ANY CO2, it will blare the holy living hell out of itself until the CO2 is gone. Also, if there were CO2 in the air, you would be throwing up, or passing out, or at the least, very very sick. If you've been in the house for twenty minutes since it went off and you are not dead, I'm sure there is nothing in the house. However, you might want to urge your parents to have it checked out tomorrow when you all wake up. If they don't, I'm 99% certain that you'll be fine. It might just be good to check and make sure.

Why does my smoke detector chirp when it's the kind that's hard-wired and not batteries?

There is no smoke in the house and I checked for carbon monoxide but I can't seem to figure out why it continues to chirp. Do I need to get an electrician to come in to replace it?
What does the back-up battery look like?
I took the cover off and I guess I'm just blind cuz I don't know what the battery looks like. Regular battery or one of those round watch-like batteries? PLEASE HELP I am going nutz with the dang chirping!!!!!

Answer
Even tho hard wired many still have a back up battery, look and see if there is one and if there is change it.
