carbon monoxide detector 1 beep image

Answer
I have worked in the electronic security industry for over 40 years, and have encountered many of my customers with this same complaint. Here are the most common causes of this problem.
1) You may have identified the wrong detector. In other words, the beep is coming from somewhere else, and not the smoke detectors. If you are absolutely certain that you have disconnected all power to the smoke detector then there is no way a noise can come from a detector that has no power. It is ether getting power from somewhere else, or you are hearing a beep from another device such as a carbon monoxide detector that is nearby.
2) Your smoke detector is one that is wired to an alarm system. In this case I highly recommend that you contact your alarm company for service because your smoke detector is getting power from a back up battery that is a part of your alarm system, and leaving the main power shut off will wear that battery down, and then you may have to have it replaced too.
3) Your smoke detector has a built in back up battery. You can shut off the main power to your detector, but it will still run on the internal battery until it dies, which could take several hours, or maybe even days. In this case you need to take the smoke detector down and see if there is a battery inside and disconnect it.
Most smoke detectors will come down by simply grasping the detector on the outer edges and giving it a twist either to the left or the right. If you look closely on the outer housing of the detector, there should be instructions on how to open it in raised lettering on the plastic. Be careful not to force it too much if the detector is expensive because most people end up breaking the housing or the mount of the device to the point it needs to be replaced with a new one.
The most common reason these detectors start beeping when there is no reason such as a fire, is because it has reached the end of it's useful service life. A very good quality detector should last about 10 years before it should be replaced, so if yours are older than that, you need to consider replacing them with new ones, and if they are wired in to your household power, or to your wired security system, then call in a professional service technician to have them replaced and tested for operation.

Is my family going to die?
Abria
Today, when I came home from school, it smelled a lot like gas. I went into the kitchen and found out the smell was coming from there. I looked at the stove. I have on of the stoves where you turn the nozzle and then the fire comes up and its numbered 1-8 for the level of fire to cook. I heard a little continuous beeping noise and noticed that the nozzle was just above 1 (on ), so I turned it off and the noise stopped but now it still smells bad. In the past we had carbon monoxide problems with our stove TWICE and had to be evacuated. We also have a carbon monoxide alarm, so when it goes off, we know but its not doing anything. I've been in the house for about 10 minutes now and I just got a minor headache. Should I be worried? I don't want to go to sleep and have neither me or my family wake up again.

The entire stove needs to be replaced and the battery for the Carbon monoxide detector as well, if you rent tell the landlord and notate it, call the fire department-it will be on their records...If everyone's passed out in the house open the windows and get a neighbor to help you drag them out, if everyone can get out...then get out and don't mess with the windows, let the professionals with air pacs (SCBA's) do the work when they get their on the truck...Nothing is risking your life over. The headache is the first sign of oxygen deprivation and CO poisoning.
