MARINE CARE DUAL WATCH GAS ALARM

[alisdair4]

I'm currently fitting a Marinecare dualwaych gas and CO alarm. The instructions a re pretty clear - don't get the sensor wet (it invalidates the warranty).

As LPG is heavier than air, the logical place is for the sensor would appear to be at the bottom of the bilge sump (which in a Rival 32 is a long way down). The actual position is a clearly going to have to be a compromise.

So, what do other forumites do?

Just below the deck, in the saloon, in my boat, IMO.

I also have a deep bilge, much of which is occupied by water tanks forward, and the bilge below the engine is probably not a good place for a gas detector.

I figure the most likely place for a leak is at the galley (it has happened, when the flexible hose perished, and the alarm worked). A bubble leak detector in the gas locker should pick up a problem if you check it when the bottle is turned on.

But make sure any access hatches aren't tightly sealed.

I have two different alarms; one has its sensor underneath the gas cooker, and the in the bilge in the engine room (in the expectation that it will pick up hydrocarbon fumes, too)

Two different machines in support of the principle of redundancy.

My gas alarm sensor is waterproof, spend the extra, its worth it, I have soaked the sensor a few times, accidently, and it,s fine, worth the bit more.
First Alarm was in R 32 "TRYVAL" (SOLD 93) I put the sensor about 300mm down the bilge on the aft end on a timber strap, protected by an "umbrella"(that sensor was not waterproof). Bill.

Thanks for all the info. I've compromised by putting it on the floor stringer next to the Nav station. It is about 18" above the automatic bilge pump, so should hopefully be OK.
