Overactive gas alarm!

[AndrewB]

There it goes again! Every time SWMBO makes toast, up fires our onboard CO alarm. Almost the moment she puts the grill pan under the gas burner. Not for anything else though - just toast. Is she buying particularly toxic bread?

Anyone else have an idiosyncratic alarm?

Our CO alarm also sometimes goes off a few minutes before the smoke detector when burning bread (no grill just a rubbish contraption on the hob which makes Shrodinger's toast - simultaneously burned and fresh bread!). I assume we may actually be making small amounts of CO, but they are not particularly specific to CO - will pick up hydrogen and a bunch of other easily oxidised hydrocarbons too.

Not CO but I had a smoke detector that reacted to a Dyson hair drier.

Does the grill burner need a service? Incomplete combustion?

Ours does exactly the same. Galley is forward of the deck saloon, and the gas detector is in the aft cabin, where we sleep. As long as we remember to close off the aft cabin before making the morning toast, it's OK. It's done it since the cooker was new, a couple of years or so ago.

I don't think the problem is the burner - otherwise it would do it when grilling other things or running empty - the CO (or other chemical triggering the sensor) is coming from the the incomplete combustion of the toast. By definition toast requires an incomplete oxidation so its not particularly surprising if it gives off some CO or other small volatile organics (it must - thats why it smells delicious).

Well my grill doesn't set off the CO alarm

There's a thread on here dating back to Xmas 2008 about mulled wine setting off gas detectors - people felt there was something missing from their ingredients if the alarm didn't go off

Is the CO alarm in the galley or in the sleeping cabin, where it should be?

What Norman said. Boats are small places. There is probably nothing wrong with the alarm.

According to the following its unlikely to be a false alarm
