    Have not seen this idea posted anywhere on the Portal. The Aliner's propane detector consumes .07 Amp/hour. That's 1.68 amps per day according to the book. In an experiment with a newish battery it appears it is more like 3+ amps per day. Test period 14 days

    There are several beginning camper threads lamenting about a beeper sounding in their NTU campers during the winter. Usually its a low battery caused by the propane detector. The boilerplate response is 1) disconnect the battery cable, 2) pull the battery fuse ,3) get a heavy duty on / off switch for it. But what if you just want to pop into the camper for a couple minutes to do something? You have to disconnect then reconnect the battery.

    The parasitic drag on the battery is .007 amp with the detector unplugged. Why cut the battery out of the electrical system when cutting the detector out cures the problem? The detector has a light that tells if it is on and functional. You don't need the detector while you are away from the camper. We are away most of the day. If you dry camp, why not only use it only when you need it? That's 20+ amps wasted.

    A toggle switch was wired in series with the detector. The switch travels horizontally in an attempt to prevent accidentally turning it on/off. It is located on the converter wall next to the detector. You can turn it on with your toe while climbing into bed.

    Electrically you are correct but life safety devices are not allowed to have on /off switches and I don't recommend putting one in.

    If you have an always-on solar system - you don't care :)

    My propane detector is kaput. I will either reinstall it with a switch (with a cover to prevent accidental flips) or find a unit that uses a 9v battery or similar (not the house battery). Any of the latter that anyone recommends?

    Why? unless it's night time, you probably dont even the battery "on" if youre just popping in for a few minutes..

    Haven't found a gas detecter that works off a 9 volt or simmiler. I dont think they exist, because they cycle the air. That means they take and purge an air sample every 30 seconds to a minute. It would deplete the battery in a day or so. Same goes for the good co alarms.

    They want it always on so you do not forget you turned it off and then have a problem.Ifthats why it does not have a **** off. Same idea behind the new 10 year battery smoke detecters, thats so people don't disconect them.

    If in storage its easy enough to just install a battery disconect switch. This way when you go into the camper and the lights dont work you turn on the battery and the detector.

    Yes, it seems like a no brainer, but when looking at fires and disconected smoke alarms, i can tell you that when people die, they have the smoke alarms up, but they have no batteries in them or disconected batteries in them. So, it happens. Its easy to say ill remember that, and 99 times you will be fine. Its that 1 percent of the time where you dont want to screw up.
