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

4 beeps with pauses for 2 year old carbon monoxide detector


I'm pretty sure that indicates an alarm. The pattern is referred to as "temporal 4" which is the alarm pattern for CO. Either your device is in a bad place or there is an intermittent CO leak which is exceeding the ppm (parts per million) threshold for a given time period. The instructions for the device will tell you what that number is. If you have more than one of these, I would try swapping them to determine if the problen is with the device or the location. Good luck!

I hve a number J90 on my detector what that means


Kidde AC Plug in Operated Carbon Monoxide AlarmKN COB LCB

The above link is to get a copy of the user guide. However, it does not show anything regarding an error code J90...in fact, I can find no reference to this code on the Kidde website. You would be well-advised to call their support number or contact them through their website: "Call our Product Support Line at 1-800-880-6788 or contact us at our website at www.kidde.com". If you get a definitive answer it would be nice if you would post it here for others to see. Thank you.

How can I shut off my Kidde carbon monoxide detector when beeping


Here is the link to the manual for your Kidde model KN-COB-LCB-A
Carbon Monoxide Detector. This may help you solve your issue.

You may find more related information on my website. If you need a replacement or you need to add additional Carbon Monoxide Detectors in other levels of your house, you can purchase them here.

This issue should be solved immediately, Carbon Monoxide Poisoning can only be avoided by making sure you have good working CO Detectors in your house, camp or recreational vehicle.
