Carbon monoxide alarm beeping

[lorger]

We are currently away in the van on hook up with no gas running and our carbon monoxide alarm just beeped 4 times. I’ve checked the book and it says a leak has been detected, is this possible with no gas appliances running.
To be on the safe side I’ve opened the door and a roof opening, the van is quite warm but I don’t think this could cause it.
It’s a fire angel alarm.

I read it like this

Ours kept alarming, it was faulty. If in doubt, gas off at the cylinder and get a new alarm tomorrow.

 

[Janine]

Mine started beeping when the hab battery was gassing.

They have been known to actuate, if your battery is venting off. Janine beat me to it.

I didn’t think it would detect a gas leak as that’s no carbon monoxide if I’m correct in my thinking

 

[Tombola]

carboon monoxide is only produced when fuels (gas) is burnt, and not burnt fully
so as long as no gas running it looks faulty (assuming you have changed the battery)

 

[bobandjanie]

If your panel looks OK and your batteries are not cooking, I would say alarm battery is low and need changing. Bob.

This was my thinking but I just wanted to make sure.

Probably a stupid question but is it fitted at the correct height etc ?

Cheers Bob I’m sitting right above where our batteries are and certainly no smell coming from them, will get new alarm batteries in the morning.

Not a stupid question as I thought the same, it’s a brand new van so you’d think so. It’s fitted at head height which I thought was wrong

I only use CO monitors with a display

CO is serious but only above certain levels , the alarm will trigger at near safe levels, but will not differentiate lethal levels

hopefully just a low battery but suggest replace with

Amazon product ASIN B00ABGEL62

 

[DavidG58]

Head height is right

Two years ago a neighbour knocked and said there is a beeping coming from your van !
We had not been near it for a fortnight so I was baffled to discover it was the alarm.
To this day I do not know what caused it.. I removed and refitted the battery, did the button test and it was fine... perhaps it was feeling lonely and wanted company

You are 100% right, sorry, I should have been clearer. Turning the gas bottles off ensures there is nothing on that may produce carbon monoxide.

Generally they alarm at 300ppm which is the 5 minute short term exposure limit if I remember correctly. That’s still a lot of CO though and over days and hours is still deadly.

For that reason, like you we only get the ones with a display on.

Long term low doses of CO can cause great harm even if they don’t rise enough to set your detector off.

 

[DelMar]

A CO alarm should be fitted 6 inches from the ceiling. CO is lighter than air and a room will start to fill with CO from the ceiling down, therefore place the alarm 6 inches down. Never at head height.

I would check your batteries tmake sure they are not getting warm.

It is about the same density as air but rises normally with the warm air produced from combustion.

Head height isn’t a bad option, the stuff gets everywhere so nothing lost. Depends on the manufacturer of the device.

Some helpful info here.

I have one of these in our van, at ceiling height, but am still not sure if that is correct?

 

[lorger]

Checked them earlier and no heat present

 

[DelMar]

6 inches from the ceiling is the correct height, If I see a CO alarm at head in MH I would not stay for long.

 

[kevenh]

Different alarm, but our MH Fire alarm started beeping.
Fitted a new battery, still the same.
RTM for the alarm.
Found - one solution was to clean/vacuum it
Tried that & it worked
Another suggestion was the battery but I'd eliminated that ^^

Six inches from the ceiling in a motorhome is head height.... unless you are a dwarf

6 inches down in the mh is my head height.

 

[Theonlysue]

A friends alarm went off, when external fridge gasses were entering the moho.

 

[lorger]

Thanks for all the replies it’s been okay overnight and I’ll change the batteries today to be on the safe side.

DelMar as most have said head height is about 6 inches from the ceiling , I’m 6,1 and it’s above my eye level.

 

[icantremember]

Not a CO alarm, but I had a mains powered smoke alarm fitted in the attic at home ... had to remove it due to so many false alarms caused by hibernating insects getting in to it, mainly lacewings.
