What does L6 mean on my Garrison carbon monoxide detector, it beeps then that message flashes, and then it beeps again . It is a plug in and does not need a battery.


L6" display & chirping sound, indicates you need to change the 9 volt battery in the detector.

Please rate me as HELPFUL.

My night hawk carbon monoxide reads L6. Then Err.


Lb (rather than L6) indicates a low battery. You need to replace the 9V battery in the carbon monoxide detector. The Err suggests an internal error but could just be due to the low battery.

If the Err persists after you replace the battery, press the peak level button (the right hand button) and check for an additional error code. If the Err message continues, replace the Night Hawk unit. If the unit is still under warranty, contact the manufacturer. Most of these units have a 10 year warranty. There are several models available from Kidde. The manual is available on the product site. For the KN-COPP-3 Night Hawk carbon monoxide detector, the documentation is available here: http://www.kidde.com/home-safety/en/us/products/fire-safety/co-alarms/kn-copp-3/ . Click on the Documents tab. The manual for the KN-COPP-3 999-0100 is here: http://www.utcccs-cdn.com/hvac/docs/2001/Public/06/User_Guide_KN-COPP-3_900-0100.pdf .

I hope this helps.

Are radon and carbon monoxide detectors the same?


A carbon monoxide detector is a device that detects the presence of carbon monoxide gas to prevent CO poisoning. Radon is a different gas that can enter your house through foundation cracks. It has its own test kit to detect traces.

My Kidde Carbon monoxide beeps every 30 seconds and is showing L6 with a flash of 0? It is brand new. What does this mean?


L6 is actually "Lb", which is a low battery warning. If the 9V battery is missing, or if the battery's power is low, an "Lb" message will display, which blink's alternately with the current CO reading, while chirping. If this happens, you need to replace the battery.

My carbon monoxide detector just has one sold beep and is not plugged in.


I assume you mean your carbon monoxide detector has one solid beep, and it is probably an AC unit. It may be safe to assume that it has battery backup if it is beeping without being plugged in.

First, you may replace the battery with a new one, plug it in and hit the reset button. If that doesn't work, you could bring it in to your local fire department to have it tested.

Check the expiry date on the Carbon Monoxide Detector. It should be replaced if it is more than 5 to 7 years old, check manufacturer recommendations.

A replacement carbon monoxide detector will give you the protection you need and peace of mind. Your safety depends on how fast you deal with this issue.

Error code keeps coming up on nighthawk carbon monoxide detector


An error code on a Carbon Monoxide Detector is a serious matter that should be looked at immediately. Your local fire department will be glad to help you with this issue.

If the error code keeps coming, it may mean that you have a defective unit. If the unit is new, you should be able to get a replacement where you boutht it. A unit that is more than 5 to 7 years old should be replaced, see manufacturer recommendations.

Browse my website for more information or for buying a replacement for a new Carbon Mononxide Detector.

My carbon monoxide detector keeps beeping in spite of replacing thebattery and gives an error code of E09. Also it keeps flashing an err on the led redout. I placed it outside and it is still doing it...


Hopefully you have found a solution for your Carbon Monoxide Detector issue of October 4, 2009. The best solution for a questionable CO dectector is a replacement.

A Carbon Monoxide Detector is the only thing that will read, detect and sound an alert when reads dangerous levels of CO levels in your house. A defective carbon monoxide detector will give you and your family a false sense of security and will give you no protection.

Whenever in doubt, always err on the safe side and replace Carbon Monoxide Dectectors, your life depends on it.

Lost manual for the nighthawk carbon monoxide detector, model no.900-0082-00 made in 11/1996. hasnt been used for several years.DON'T KNOW HOW TO SET IT.


Hold on!

All carbon monoxide detectors have to be replaced after 5 years of manufacture date. The sensors are not reliable after that time and may give false readings.

A carbon monoxide detector is your only defense against the hazards of Carbon Monoxide Poisoning. I would never recommend installing a used Detector. Ask your local fire department for more professional advice on how and where you should install carbon monoxide detectors.
