100%, but tell that to the sensorAn electric heater should emit no harmful gas, nor consume O2. When I head to my hunting land on weekends in the winter I put the propane heater on long enough to get the chill out and then turn on 2 electric heaters and the electric fireplace, that is nothing more than an electric heater. It is a 34footer so it takes more than one heater to heat that area. I am a little unclear what alarm is going off but I would not worry about it as long as you are sure the propane tank is shut off. An electric space heated can't kill you with CO, HC, or any other gas for that matter.
