When a Carbon Monoxide Detector alarm goes off, you should follow the procedures that came with the manufacturer manual. Even when the alarm sounds, you cannot smell, taste, or see this dangerous silent killer known as Carbon Monoxide.

Have your house checked by your local fire department for possible levels of CO gas readings. If this all checks out, you can go online to Kidde Nighthawk website and find the manual for your Carbon Monoxide detector model.

Hopefully, you found your solution since you posted this question back in Dec, 2008. Go to my website to read industry information and to view most Brands and Models of Carbon Monoxide Detectors.

I have a nighthawk carbon monoxide alarm which is showing nan error code. Please can you tell me what to do to rectify it? Thank you.


You can unplug the unit if it's an AC detector, change the battery for a new one and reset the Carbon Monoxide Detector. If that doen't work, you can have it checked by your local fire department. If the unit is more than 5 years old, it absolutely needs to be replaced.

Whenever in doubt about the efficiency of a carbon monoxide detector, a replacement is recommended. Yes, protection has a price, but a life cannot be replaced.

Good Morning, My nighthawk CO detector went off with a loud continuous alarm this morning while all were sleeping. I reset it and it is not alarming now. I pushed the peak button and it reads 19. The...


When a carbon monoxide detector sends an alarm, there is cause for concern. You mentioned that the other CO detector did not go off, but maybe it is too far away to monitor the carbon monoxide levels that was in this area.

The instructions in your manual would direct you to evacuate the house immediately and ventilate. Your next step is to get a professional to inspect what may have caused the carbon monoxide leak.

A reading of 19 indicates that there is carbon monoxide in that area of your house, unless your CO detector is not working properly. Your local fire department will give you the best advice for what action to take when a carbon monoxide detector sends an alarm.

Be safe, don't assume a carbon monoxide alarm is cause by a defective CO detector, have it inspected.

A reading of 221 ppm carbon monoxide gas is a dangerous level that should be taken seriously. You could try a new battery and reset the detector. If in doubt, always err on the cautious side and have the apartment checked by a professional or by the local fire department.

A new carbon monoxide detector is a small investment that may prevent carbon monoxide poisoning or death.

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.

My nighthawk Kidde carbon monoxide detector keeps beeping every 25-30 seconds. Do I need to buy a new one?


Some models of Carbon Monoxide Detectors will give an audible beep every 25-30 seconds after it has sounded an alert alarm. This may have happened when there was noone home to hear it. A periodic beeping sound may also indicate it is time to change the battery.

Solution: Install a new battery and check your manual for instructions on how to reset the system. Check the expiry date on your unit, it needs to be replaced after 5 to 7 years, according to the manufacturer specifications.

If you are in doubt that your Carbon Monoxide Detector is not working effectively, REPLACE IT. Your safety and your peace of mind is worth it.

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.
