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.
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.
