In my house at Gamone, I’ve just assembled and installed two alarm panels like this:
The alarm on the left is a smoke detector, while that on the right detects lethal carbon monoxide gas. They both run on batteries.
I’ve installed one panel in the staircase, in the vicinity of my ground-floor wood-burning stove. The other panel is installed on a wall in the kitchen. These detectors are not expensive, and they’re easy to install. So, I’ll probably get around to installing other identical panels throughout the house.
My son François told me that he inadvertently tested his CO detector when cleaning the interior of the chimney pipe that evacuates smoke from his wood-burning stove. There were two 90-degree bends in his piping (which have since been eliminated thanks to a single vertical pipe from ground level to the roof), and it would appear that CO had collected between these bends. Consequently, as soon as François started to brush away the soot that had gathered in these bends, the CO floated down into his living room and set off the alarm.
François and I both felt that it would be reassuring if we were able to test our smoke detectors… without setting fire to our houses. At lunchtime today, I succeeded in doing just that, thanks to half-a-dozen barbecue sausages from my deep freezer. I cooked them on a flat iron pan of the kind used for making pancakes, heated by my gas range. Naturally, as the temperature rose, and the sausages sizzled, a bit of smoke escaped from the pan. Suddenly there was a piercing whistle, but I had no idea of its origin. Since I was also using an induction plate to cook vegetables to accompany the sausages, I had the crazy idea that the molecules in the induction system might be “resonating” weirdly and catastrophically… and I half-expected something to explode. The whistle continued to shriek. Finally, I noticed that the smoke detector was also flashing a red lamp… and I realized what had happened. So, I rushed to the kitchen door and opened it to let out the smoke, which ended the whistle shrieks.
