YES!!!! If this unit is working properly you should not be in the house. Maximum allowable safety level for an 8 hour period is 50! If you think it's working properly call the fire department! This will cause dizziness,nausea,etc. Let your fire department find the problem! If you don't believe me follow this link to owner's manual but do it quickly: http://www.kiddeus.com/utcfs/ws-384/Assets/KN-COB-B(9CO5)en.pdf

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.

Relocate it to an area of fresh air - outside will work.. Does it still beep?
If yes, recover the new battery and toss the unit.

Do you have it located in a steamy damp area? Laundry room, bath room etc.. That will cause it to malfunction too..

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
