20 Most Recent Kidde Carbon Monoxide (KNCOBB) and Smoke Alarm (0916) Value Pack Questions & Answers

No.

Most units being made today have a battery backup. If the battery compartment is not plainly visible from the outside it could be underneath (also the location of the model number and date code). Most smoke/co alarms are removed from their mounted bases by turning counterclockwise, usually about 1/8 of a turn. If the device is more than 10 years old it (the entire unit) must be replaced per the National Fire Code, NFPA72. Otherwise, you my find the opening for the battery underneath as well. There are a few that do not have a battery at all. To be sure, locate the manufacturer and model number and check the appropriate website.

It is LB...low battery

according to the second page of the manual (found online at the link provided), it sounds like your detector has reached end of life and must be replaced. CO detectors have a finite life span.

replace the battery? hopefully it is not actually reporting carbon monoxide.

replace the battery??

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

Check the manufacturer's website.

Get one of the new 10 year models.

The numbers on my CO detector indicate the concentration of Carbon Monoxide in the room. The manual for most Kidde Alarms are here: https://portalgb.knowledgebase.net/display/4/kb/browse/cat.aspx?cid=88327&kb=16372&L1cid=88309&L2cid=88327&level=3&r=0.06986403&tab=browse . For some models, it will display the peak CO detected (if the peak level button is pressed).

Do not assume that the alarm is in error. Please have the exhaust vent, pipe and intake (for some tankless water heaters) checked for blockages or disconnected pieces. (You can check some of the vents pipe yourself - like the connection from the water heater to the pipe. Depending on your building, you may need a professional to check the vent on the roof and the pipe from there.) Also check the flame color of the water heater. For natural gas, you should see a blue flame. LP usually has a little bit of yellow in the flame tips. CO is the result of incomplete combustion. See this page for an idea of the flame color: http://www.appliance411.com/faq/gas_range_flames.shtml . If the flame is the wrong color, get the unit fixed.

I hope this helps.

(who has had the CO detector indicate a major problem. Fortunately it was easy to fix. I hope yours is also simple.)

chane your power supply or battery

probably time for a new one. Most instructions for these types of units will tell you if it does the chirp after new batteries are installed, the unit has likely become defective. You got your money's worth from the unit. You can get better ones noew likely cheaper than the original one.

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.
