Alarm keeps beeping, reads 0

Our alarm (900-0113) has sounded briefly (3 short beeps) 3 different times today.  The display continues to read "0", nothing else.  I changed the battery thinking that was the problem, but it happened again since then.  I am thinking that it is malfunctioning since it still reads 0 after testing it.  There is a blinking red light next to the 0 which, according, to the manual, means it is working.  I have two small children at home so do not want to misdiagnose.  Thanks.

Alarm keeps beeping, reads 0

Try testing it first. Press the test/reset button. If it's operating properly on the display: "GAS" - and it should beep 3 times. Then a number should appear on the display. It should be arround 200. Then it should beep 4 quick times, then nothing for 5 seconds, then 4 quick beeps that keep repeating. It will then show 3 numbers again for a few seconds. When they're gone it will be done resetting. It should show a flashing red light and a 0 or whatever the reading might be. Try this and let me know what happens. If this fixes the problem please rate as fixed. If not, please don't rate yet. Let me know what's going on and I'll be more than happy to help. Thanks.

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 number it reads is 245 when I pushed the test/reset button. I have a second CO detector in the house and it didn't go off. Any ideas what could have triggered this to alarm? Also, is the reading of 19 significant? Thank you, Carla Hornung

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.

The detector has gone off two times within the last week. The detector reads "GAS" when it goes off. THe number the first time was 199 and yesterday is was 235. The first time I got out of the house, called the fire dept and they came and checked the house. They found nothing. The second time, I just turned it off, put it outside and it stopped beeping. Once I brought it back into the house, it started beeping again. I just left the house - not calling the fire dept. Not sure if is malfunctioning - or if there is "GAS" in the house. Is there a way to check to see if it is malfunctioning - or if it is a true problem. (The two alarms were a little more than a week apart - and no beeping in between the alarms). We don't have natural gas, just propane. Fire dept checked the only three appliances that run on propane, and said they were fine. Any suggestions??

Propane is heavier than air so if the detector is mounted ABOVE the appliances that use it (or any tubing that brings the propane into the house) it (the propane) will NOT be detected, even if there is a leak. That said, the PRODUCTS OF COMBUSTION of a propane appliance will still contain carbon monoxide (CO) which is lighter than air and will be detected by a properly installed detector. If you continue to get alarms and readings that differ from each other, along with no error codes on the display, it sounds like the detector is really detecting something. If the fire department cannot identify a source, try calling the Kidde "Hotline" at 1-800-880-6788 and ask if they can recommend another agency in your area to check your premises. I don't think these units detect Radon but am not sure. If your dwelling is of relatively new construction, the problem can be complicated by the fact that there is less outside air infiltration to disperse any build-up of gas/radon/CO/etc. than is typical in older construction. *Disclaimer: I am not a lawyer, despite the handle.
