Kidde Recent Questions, Troubleshooting Help & Support

Check the Kidde website for the manual for your model to get specific info...I'm sure it's probably an error indication, but without the model number it's hard to look up.

It is LB...low battery

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.

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!

if it is about a smoke alarm with a battery in it, when the alarm beeps for no apparent reason, it is a bult in indicator that the battery is flat or approaching a low voltage and needs replacing If it still beeps after replacing the battery have it checked out as a fire alarm is critical for your safety

certainly will -- same as low battery will set of the smoke alarm

send the detector back and have it replaced, The CO sensor will not alarm to levels of CO below 30 ppm and will alarm in the following time range when exposed to the corresponding levels of CO: 70 ppm CO Concentration 60 - 240 minutes 150 ppm CO Concentration 10 - 50 minutes 400 ppm CO Concentration 4 - 15 minutes The alarm shall include a piezoelectric horn that is rated at 85 decibels at 10 feet. When the unit detects carbon monoxide, the alarm pattern will be four (4) short beeps - followed by five (5) seconds of silence - followed by four (4) short beeps. The unit shall incorporate 2 LED's. A green LED will be illuminated to indicate the alarm is operating properly when plugged into an outlet, and will flash every 10 seconds when on backup battery power. A red LED will flash to indicate that carbon monoxide has been detected until the device is reset or CO is eliminated or will flash to indicate low battery or alarm malfunction. The unit shall at a minimum meet the requirements of CAN/CSA 6.19-01. It shall also include a 10-year manufacturer's limited warranty or Test/Reset Button - Tests the unit for proper operation. Resets the carbon monoxide alarm. • Tamper Resist Feature - If activated, unit goes into constant alarm mode if it has been unplugged or has come loose from the outlet.

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.

Change the battery and see if that fixes it.

low battery, replace battery

You can probably find the manual for your device at this link: https://portalgb.knowledgebase.net/display/4/kb/browse/cat.aspx?cid=93152&kb=16372&L1cid=93132&L2cid=93139&L3cid=93152&level=4&r=0.8358809&tab=browse

Air may flow through the unit if you don't have a vapour barrier wrapped around the electrical box in a ceiling with an attic above. The smoke detector may look smoky and it may have come from cooking grease in the air. This may foul the smoke detector. All smoke detectors have a piece of radioactive americium-241 that creates ions in an ionic chamber. This chamber has to be pristine. That is why smoke detectors have a replacement date on them. It may be time to get another one. Some kits come with a cardboard baffle to stop so much air sucking through the unit.

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

replace the battery??

Dale, My alarms beep like that to warn me of batteries needing replaced. What I do is hit the test button and ensure it sounds. I would still replace the battery(ies) and retest when you do.

The unit probably needs to be replaced If you need further help, I’m available over the phone at https://www.6ya.com/expert/justin_3ae27a9d61d6acd4

Be sure you are using a well known brand battery. The store brands, in my my opinion generally are not quite up to par. Try this and see if the chirp will stop. Thanks for asking me.
