You don't mention how old the detector is. If it is more than 5 years old the detector may be beeping to indicate the end of its service life. A smoke detector can last much longer but carbon monoxide detectors have a limited life span. If putting in new batteries doesn't fix the problem then most likely you will need to replace it.

Some models of Carbon Monoxide Detectors will give an audible beep every 25-30 seconds after it has sounded an alert alarm. This may have happened when there was noone home to hear it. A periodic beeping sound may also indicate it is time to change the battery.

Solution: Install a new battery and check your manual for instructions on how to reset the system. Check the expiry date on your unit, it needs to be replaced after 5 to 7 years, according to the manufacturer specifications.

If you are in doubt that your Carbon Monoxide Detector is not working effectively, REPLACE IT. Your safety and your peace of mind is worth it.

My Smotec 3786A indicates not to install it in above 85% humidity.
One of my three seems to go off annually or so and this is what
recently put it down to. I was making an espresso coffee on the
stove and it generates a lot of steam and off goes the fire alarm.
I did change the battery to no avail.

Detecotrs have a limited lifespan of 5-7 years. So sounds like you need new one (It's not worth to buy just a sensor). Take a look on amazon: Amazon com Carbon monoxide detector (watch out on reviews). I hope this was helpful. cheers
