Battery operated propane alarms?

Hi, folks.

I am wondering if anyone has found a battery-operated propane detector and/or alarm that they like. I am holding off on wiring any constant-draw devices into my wee 2004 Scamp 13 until I have a better sense of how much propane I use when camping off-grid (or at least without electricity).

Thanks!
Kathy

Look here: https://www.mtiindustries.com/produc...ti=0&ci=1&si=3
but I don't think you'll find a battery operated alarm.
The draw from your house battery will be minor. Your furnace fan is the real draw.
If storing, you can just disconnect the battery.

Kathy, here's another way you could go although some may not agree. I installed a switch next to the monitor so I didn't have the battery draw but could still turn a light on if I needed to while it's stored/parked. I've just made it a habit to turn it on when I light the refer etc.

"fools seldom disagree"....lol

me too, I put a switch in that circuit....I know, I know I'll be dead anytime now


I got tired of getting up at 4 in the morning because the alarm had gone off parked in my backyard after a few days in the winter (suspect CO2 alarm).....also in my unit the alarm is located across the aisle from the stove/oven so every so often when I used the oven the alarm would go off.


I located a toggle switch near the floor, around a corner out of the way of normal foot traffic....it is "on" in the down position (the only way it could be accidently tripped would be from the off to on position)

Pull fuse

When I picked up my Scamp last month, they had the fuse pulled from the detector so that it wouldn't drain the battery when waiting for me to pick it up. Seems like a pretty simple solution when the trailer is in storage.

The problem is the technology used by most flammable gas detectors draws a fair amount of current, and would result in limited battery life. No problems for smoke & CO detectors, but the propane generally runs of the larger trailer battery.

Battery and AC Operated CO2 & Propane Monitor

Hi There!
I just installed a fabulous combo CO2/Explosive Gas Detector which can be operated by battery and or AC. It's made by Kidde and I bought it for about $49 at Home Depot. I saw it featured on a UTube video and the old timer at H.D. said it's the best they've carried. Installation took about 5 minutes.

I just order a First Alert CO400 from Amazon for under $12 + tax, regular price around $33, operates on a 9V battery.

That would be a carbon monoxide detector, not a propane gas detector.
And, CO2 is carbon dioxide, which is what you breath out all day and night.
CO is carbon monoxide and a killer.

Actually most all of the RV propane detector / alarms are battery powered... the battery being the house battery (supplemented by the converter / charger when on shore power).

And the reason is that they wont last long enough on smaller batteries. You might get a week out of a pair of D cells, but much less time with smaller batteries.

My recommendation is a battery cutoff switch that shuts off everything 12 volts in the camper from the battery, including the gas alarm. The switch is used when the camper is unoccupied AND the propane tank is turned off at the valve or removed all together.

At other times the gas alarm should be used, and the battery kept up by whatever means are appropriate (shore power, solar, weekly hookup to a charger, etc.)

Now if you find yourself in a situation where you cant recharge the battery and you need every Milliwatt possible out of the battery to keep from freezing to death, then its reasonable to remove the fuse to the gas alarm and take your chances on a gas leak. I would suggest that you do NOT install a switch to the alarm however because its just too darn easy to flip it and forget about it, leaving you without a gas leak alarm.

The previous owner of my
scamp 16 had a switch installed which shut down 12v to the alarms, heater and water pump, but left power on to the lights. hard to forget to flip the switch back on.
A useful mod.

Thank you all!

Thank you all for your thoughtful responses. I will purchase (and use!) an explosive gas detector and alarm, and unplug or disconnect when the Scamp is in storage or when the battery is in desperate need of recharging.
