Can you smell gas !

if they heard an alarm they would notify us.

Clever....that way you can stay away until the gas dissipates or explodes

I keep our Pixie in a marina, the staff there walk around all the boats at least twice a day, if they heard an alarm they would notify us.

And yep I do turn the gas off at the bottle when we leave the boat, but only at the shut off inside when we are on the boat.

Wiring it in permanently also stops it beeeeeeeeeeeeeping when we first get on the boat.

I theory there should be no way of gas getting into the boat when we're not there. However with a Sadler 32 the cockpit drains exit under water, so I've added another drain that should drain the gas out before it fills up the boat. If that pipe were to block (38mm id so unlikely), there is a chance that gas may enter the boat...it's a remote chance, but the thing about freak accidents is they don't happen often

However...

I have a dislike as a matter of principle of wiring up anything without providing a means of isolation.

It is also worth considering what current the gas alarm draws. I have a 2 detector Pilot which draws a standby current of 170mA. That's over 4Ah per day, so if, while you're away from the boat for a fortnight, some clown trips the pontoon supply, you're likely to find a flat battery when you return. It's happened to me twice so now, when I'm not aboard, the gas detector is turned off. (As is the gas at the bottle, naturally.)

The start up test beep, while certainly annoying, in reality only goes on for a few seconds not "several minutes" as claimed in one previous post.

30 seconds is what I said. That came from the manufacturers instructions.

My gas alarm is wired in the otherside of a relay on my smartgauge that cuts out when the battery capacity goes down to 50%.

I also have a wind gen.

I wasn't referring to your post but to your posted link:

Bluddy thing, it came with the boat, complete with the single head and a couple of meters of cable, it used to do my head in, get on board, switch batteries on and BEEEEEEP! for about 3 or 4 minutes, Dunno whether its supposed to do this!
