sounds like a false alarm BUT get it checked out before using the van.that stuff

YOU CANNOT SEE IT / CANNOT SMELL IT / CANNOT TASTE IT / AND DEADLY             

Did you have a bonfire in the garden? Were you smoking a large Havana?

Sounds like a faulty detector to me

ive heard of this before on very hot days in new vans but not sure if it would happen in older vans or not

something about the fumes released from glue and plastics in the furniture and foam backed window blinds ect when they get very hot from the sun, was it a sunny morning where you live? remember even if it wasnt hot in your garden it could be very hot in your van if your curtains vwere open

was there a car running nearby as im a gas engineer and they are quite sensative to car emmisions

if not get everything checked by a lpg gas engineer

but if there was nothing on and no gas conected it must be a false alarm

Check on your battery in the detector.

It was a very sunny day on Sunday and quite warm. May be something to do with fumes in a new van. Still odd isn't it? Anyway rang SF Detection in Poole this morning and they couldn't understand it either. I have sent alarm back and they will check it and replace it.

No. There wasn't any car running near by and next door's gas fire outlet is way up high but is nearer the caravan than ours.It was quite windy on Sunday so I think any fumes outside would have been blown away and dispersed.Not taking any chances though. We have another detector which we use in the house. I am going to put that in the van tomorrow for the day and see if it happens again.The weather forecast is warm and sunny like it was on Sunday.

Thanks for your advice everyone. Greatly appreciated.

Carbon monoxide is produced from incomplete combustion, so unless something is actually being burnt, it cannot be produced in the van. Like kaceyjosh suggested, sometimes when you leave the car running to demist windows and get the heater going the fumes from the exhaust are blowing straight at the caravan, in through the vents so set off the alarm.

your right about how carbon monixide is produced

unfortunately just as steam and dust can give a false alarm in smoke detectors, certain fumes from chemicals can do the same in  carbon monoxide detectors due to the way they work

 

anyway op you have done the right thing getting the comany to check it out and tbh if they are a decent company they should send you a new unit just incase

I had this experience  when drycamping in the high desert, in the middle of nowhere. 

Our battery was depleated after 2 days (it was the original battery, and at the time 3 years old.) In the middle of the night the co2 detector chirped & beeped scaring us awake. Thankfully, all was well and no gas leak. Next day we went 60 miles to the nearest big town with a local tyre shop and they graciously recharged our battery up for us.

I am hoping that your problem will be as easy to fix.
