Just got a gas alarm from Lidl £10.99, It has a mains power supply but this gives out 12V DC so it should work off the boat battery.
 
I got one too! Says on the box that can be used for boat. Instructions say to unwire the transformer and wire alarm up through a switch. A previous post just said chop the transformer off and use the wire provided!
 
Re: Lidl gas alarm - where to put it?

Needs to mounted low down. I thought that next to the battery switch (which is low down in my boat) might be a good spot so that you see it before you use the switch.
 
I bought one around a year ago, and yes It works very well on the boat. sited under the cooker it will detect an unlit burner in about 10 seconds. The current draw is relatively high at around 30mA so you may not want to leave it on when not onboard. Unusually, the wall-cube in fact supplies 12v AC, and the alarm itself incorporates a bridge rectifier so a DC supplied can be connected either way around.

Bought one of these today, looks useful, thanks for the tip.
One little worry though, the instructions say, "under no circumstances install in areas under risk of explosion"
Like, for instance, where there may be a gas leak?
 
Yes bought one last year, and again its in locker below cooker, and it does work well.
It was £1 cheaper last year, but still a lot cheaper than other places.
 
SWMBO says anyone who shops in LIDL deserves to get nits (allegedly!) - I shopped there once and got away with it so it may not be true (although I am a bald b*stard) - got a gas alarm fire blanket and 2 fire extinguishers last time they were on offer
 
The circuit board on the one I got had a place for the 7810 regulator ( three pre drilled, plated holes with a jumper near the input wires) This made it stable over the battery range and allowed me to use the mains adapter for my Lidl weather station at home... Also, I unsoldered the sensor, and put in on a long wire to the bilge, re-set the sensitivity pot, so now have a proper setup. (then sold the boat - need to start again!)
 
Fitted one about a year ago wired direct to 12v works very well, when first powered up gives a test sound so you know its working.

Fitted below the cooker was very surprised when it when off cpl of days ago as i was using some spray glue in the aft cabin. Surprised how sensative it is as I was only spraying glue for a few seconds.
 
I really can not understand how anyone could rely on these things which were never designed to be used on 12vdc or indeed a boat. It surely is only of any value when the sensor is in or very near the lowest part of the hull, you could have a lot of cubic meters of explosive in the boat by the time it reached a sensor under the cooker, for example?

They are designed to run on 12v, that's why they come with a 12v transformer and they are also designed to be used in boats and caravans - I bought one today and it tells you all this in the instruction manual.

A better question would seem to be how anyone could rely on these things which were never designed to be used on 240vac or indeed a house.

If you mount it under the cooker, it is triggered by the gas passing over the sensor on the way to the lowest part of the boat. seems a pretty sensible place to put it to me - the manufacturers seem to think so too.

Possibly fine if the leak is from the cooker, but it may not be the source, hence the need to have the "remote" sensor as low as poss. As I said you could have a big bang when the pool of gas reaches the cooker and sensor. I suupose if you have a 10quid family/life/boat to protect 10 quid gear is ok?

The cooker is the only source in my boat, the cylinders are in a fully vented locker with only a couple of foot run of pipe direct to the cooker. Even if gas somehow found it's way into the boat from the gas locker it would still pass over the alarm on the way to the bilges. So it is more than possibly fine, it would be less effective to put it anywhere else.

If the ten quid gear works properly what's the problem - I have five quid smoke alarms, thirteen quid fire extinguishers and a twenty quid CO detector. What's price got to do with it? Not a chandler by any chance are you?
 
Nice boat the Seadog Mark, but I still maintain that that type of gas detector is not designed for most boats, and could lead to a false sense of security, I don,t know, but assume your bottle is in a cockpit locker, as is mine, and all being well, self draining, but the principal remains, it is better to detect the problem while it is well below sole level. IMHO. Bill.
 
Just make sure to check the drain on the battery. I installed one - well known make - that drained the 85 AH battery completely in about 10 days...

Good point, mine is a "nereusalarms", not cheap but waterproof sensor, very sensitive and not too hungry. Scored high in a PBO survey.
