Gas alarm going off

I got so mad at my propane alarm that I took out some wire cutters and disabled it. The darn thing would go off when I didn't even have the propane tanks turned on. On day I had to keep resetting it for over 20 minutes before it would turn off. I know that sometimes my wife's hair spray would set it off. Other times, the dogs would set it off. The last time it went off I could not get it to stop. The wife and dogs were outside, the propane was turned off and the windows were open. After 30 minutes of constantly resetting it, I disabled it. I have since purchased one of the portable units that plugs in a 110 AC socket. I plugged it in close to the stove which would be the most likely place for a propane leak. I will eventually get around to replacing the original one. It did have a date on the back and it was almost 5 years old when I disabled it so it was likely in need of replacement.
