carbon monoxide detector beepng
My carbon monoxide detector is starting to beep when I'm not hooked up to 110 or hooked to my truck. When sitting out in my driveway unhooked it will beep after awhile, I push the reset button it will stop then after awhile it will start again, I'll plug in the 110 and it will stop. Dose anyone know what it could be does it have a back up battery there's nothing in the manual thanks for the help
