SOURCE: The night hawk carbon monoxide

"L6" is actually "Lb" which means "Low battery". If you just bought the battery it may be defective. Try a different, known-good one. If it works OK, return the first one for a refund.Make sure you are buying brand-name batteries, EverReady, DuraCell, etc. not some cheap knock-off brand you may never have heard of. There is absolutely no quality control or minimum performance specifications for batteries that are marketed in the US and there is some REAL trash out there. If known-good batteries are not lasting at least a year in the unit, call the Kidde "Hotline" at 1-800-880-6788 and discuss the problem with their technical support section; you may be due a warranty replacement if the unit is still in warranty, usually 5 or 7 years depending on the manufacturing date. *Disclaimer: I am not a lawyer, despite the handle.

SOURCE: 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.

My unit keeps chirping every 30 seconds even after replacing the batteries. The unit is over 5 years old.


The manufacturer has written this in their manual for your unit...

"Err" displayed -battery icon may show any state of battery capacity. One quick beep every 30 seconds. Unit is Error condition

Replace batteries. If "Err" (or blank display) continues, unit has malfunctioned. Replace immediately.

How do I reset the Hawking HWR54G to factor settings - delete passwords and security settings?


Hi,

At the back of your device next to the WAN Port (internet port) you will find a small hole with a button inside it, turn your device off then press and hold the small button in while switching on your device, keep pressing down on the button for about 5 seconds, that will reset your router to default settings.

Keep Moving Forward.

Carbon monoxide detector err code


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

Make sure all disks are ejected first. Try holding down the power button on the front near where you put disks in. Keep it held down until it beeps a second time (5-10 seconds after the initial/first beep). Get updated to version 2.2 (came out last night). Good luck!!
