    If the gas bottle is nearly empty, you will sometimes notice the smell of mercaptin (?) which seems to get concentrated in the bottom of the tank. There is no more gas than usual, just more smell.

    Some detectors have a switch on the side that could have been moved while cleaning - otherwise you will just have to trace the wiring back to its source

    LPG detectors will also react to alcohol and similar chemicals so once you get it powered up you could do a very rough check by holding a pad soaked in any spirit close to the detector.

    Would be unusual not to have a switch because the detectors commonly draw 100mA and will soon run a battery down if the van is idle.

    Hi

    Are you sure it's an LPG detector and not a CO ?

    RVs usually have CO monitors in the bedroom, (I think it's a US requirement), they also have a green light, lit when 'normal', it doesn't have an on/off switch. Mine is fed directly from the 12v lighting circuit and has an in-line fuse hidden in the panel behind the detector.. worth a look ..

    LPG detectors usually mounted low to the floor and CO and smoke detectors up near or on the ceiling

    It is deffo an LPG detector at floor level, I also have 2 carbon monoxide alarms.
    Anyway I have just taken it out and its been disconected !!
    By the way my LPG tank is almost empty which might explain the smell, so im off for a top up and will keep an eye or should I say a nose on it.
    So all I can presume it was disconnected due to it using power ?? so next question is is it worth having it on all the time ? I dont understand much about ampage but I do have a 130 watt solar panel, though my 4 x 110ah batterries often run down as I spend almost all my time in my RV.

    recent thread here or maybe on another forum where people claimed to be able to tell when the gas was about to run out by the smell. Betty is right 100% of the time

    Mine has never gone off for a gas leak by\ut it did save a bottle of rum once. Bottle on top of fridge tipped over and was dripping slowly onto the floor next to the alarm which went off. Another time a bottle in a case of wine under the seat on the other side of the doorway broke off at the neck and there was a small quantity on the floor. Again the alarm went off.

    So it does have its uses.

    Yes, it should be on all the time you are occupying the van. Needs a switch or a fuse to pull if you are laying the van up for more than a few days.
