The CO/Propane detector alarms when the battery gets too low to operate properly. This is usually below the level you want to draw the battery down to so as to prevent damage to the battery. If you plan to do a lot of boondocking, I recommend a second battery. I would not recommend disabling the CO/Propane detector. See battery chart below. It is recommended that you do not draw down battery more than 50% on a regular basis.
