Co sensor (1 Viewer)

[Manxcat]

Just curious

Watched a video review earlier of a van which does not have gas. Solar Panels and an inverter power an electric hob etc.

There was a CO1 sensor above the hab door.

Why would you have such a sensor when there seems almost no change of carbon monoxide existing ?

Placing the sensor up by the roof seems daft as (from my school science days over 50 years ago) co1 is heavier than air and sinks to the floor. Anyone sleeping well below the sensor would therefore be dead before it went off.

Am I missing something?

 

[Lenny HB]

Nope, lots of people fit them in stupid places, I fitted mine in the bedroom area on a side wall 150mm below a locker so plenty of air flow around it.

CO2 is heavier. CO is lighter than air and therefore rises. At least that's what I was taught at school.

I would be interested to know if this is a British NCC approved van ?
As already said it seems that some manufacturers are fitting both the CO alarm and smoke detectors in the worst possible locations?
But as usual in this industry nothing will happen and it will carry on regardless

Carbon Monoxide is slightly lighter than air, @ 1.14 kg/m3, air is approximately 1.293 kg/m3.
So Carbon monoxide (CO) may rise in an static environment, given the slight density difference it is most
likely to mix in a living environment. Best to place sensor as NEAR the source of CO.

Skipping over fire risk of lithium batteries I presume provide power to inverter.

There is no fire risk with LIFEPO4 batteries.

 

[Two on Tour]

There is no fire risk with LIFEPO4 batteries.

So you have no devices with Li ion batteries on your van then Lenny ? ar, but you already have a CO monitor.

CO1 is the post code for the centre of Colchester, do I need an alarm to warn me it is dangerous?

Sounds a good idea. I once went to Colchester.

 

[Deep Owl]

I have a CO monitor up by the controls and another Trigas (Linnepe) monitor below the bed, so lighter or heavier I don’t care! The Trigas is not a CO monitor.

What #3 said. Like you I thought CO was heavier than air until I actually read the instructions that came with my alarm. Luckily still alive . . . .

LPG will sink hence the drop/spill vents in motorhomes and caravans. Carbon monoxide generally will just mingle with air but as the source of it is often heated it may rise.

The best location for one is at sleeping head height but often instructions state standing eye level in order to make reading the display easier.

I didn't realise till I was told by the chap doing our annual boiler maintenance but carbon monoxide detectors only have a max 10year life. Apparently they lose sensitivity.

They often have the expiry date marked on them.

We changed ours at home last June, a year early.

Every day's a school day..
FYI Smoke detectors have an expiry date as well..
Best to note as after that date it may not alarm resulting in your expiry date.

 

[Pausim]

I decided to check the date on one of my home CO alarms last night (Kidde). No date but it says it will shut itself down after 10 years operation and emit a double beep every 30 seconds. There is a one way switch on the back to permanently silence it for disposal.

I assume they have a water heater that uses diesel?

Edit, note to self - "read entire thread"

 

[Jez1966]

Meandering a little with the thread, BUT.

If you bought NEW or VERY NEAR new as we did (secondhand from a dealer @ 4 month old),
did MH come with 1 or more fire extinguishers installed?
I was astonished it did not.
2 installed, 1 by hab door in reach from kitchen and 2nd at the end of the island bed to fight out with if necessary.
Also a fire blanked fixed to the wall, the right of hob, shoulder height.

Had 3 new Motorhomes never had a fire extinguisher, smoke alarm or CO detector always fitted them myself.

 

[Pausim]

Neither of my new motorhomes came with a fire extinguisher. Both had dealer supplied smoke and CO alarms.
