Carbon Monoxide Alarm £5, Morrisons

[skyflyer]

No idea if it was just my local store (Malvern) but CO alarm (runs on 3 x AA bats included) with digital display discounted down to £5. (price ticket said £7.50 but I was charged £5 at till)

Doesnt seem to be available online so i suspect its clearance stock in some stores only

What British Standard specification does it comply with?

BS EN 50291-1:2018. which is only suitable for domestic properties
or
BS EN 50291-2:2010 which is also suitable for mobile use ie caravans and boats

or is it an old model that complies with an older standard.? If so which ?

So if it is the domestic version, in what way won't it work on a boat?

It will work but those that comply with part 2 have been subjected to extra tests to ensure that they are suitable for the rigours of mobile use.

Maybe someone with a better memory than mine will remember some details. Robustness of battery mountings ???????

Some alarms would comply but simply have not been tested to part 2.. There is/was a popular Fireangel alarm with a digital display (CO-9D) that fell into that category but I think it may now have been tested.

Neither, it is EN 50291-1:2010 + A1:2012

I would imagine that the marine type has to have a degree of corrosive atmosphere resistance?

[edited to add] Just Googled it. Those for marine and recreational vehicle use are tested to ensure they will withstand vibration and movement.

My (domestic only) unit does seem to have survived the journey from factory to distribution centre, distribution centre to supermarket and supermarket to home without a problem however.

I actually bought it for domestic use though as my old one is over 7 years old although still testing fine.

That's the old standard which has now been replaced by EN 50291 -1: 2018 I don't know if there are any technical differences or whether it is purely a paperwork exercise to simplify a confusing system but it is probably why they are being sold off cheaply.

 

[skyflyer]

Legally they have to be fit for purpose no matter what price they are sold at, so i suspect little difference.

Its a bit like 15th, 16th, 17th etc edition wiring regs. Because they come up with a better/safer spec, you dont really have to rewire your house every time!

That's not why the CO-9D wasn't listed as suitable for marine use. The digital display is not fully sealed and might fail in a marine environment, although the alarm would still function. Unless they have sealed the display, it's hard to see how it could have passed certification.

I've had a CO-9D on my boat for several years. Neat little unit, no sign of failure at all. I don't fully understand how much vibration an alarm might be subjected to in a typical sailboat.

It looks like the same very anomalous situation still exists

The FireAngel CO-9D........
.
Product Life: 7 years
.
CE marked and Kitemarked to BS EN 50291-1 (domestic use) BS EN 50291-2 (camping, caravanning and travel)
.
.
Please Note: The FireAngel CO-9D is not suitable for use in boats.

Mine must be almost 7 years old now. The digital dispay is abit of a gimmick. Sounds like a good idea but the novelty of regularly checking a display that always says zero soon wears off
