[QUOTE="Phoenix, post: 499729, member: 8133"] Thanks for the information, it just looked like there was something missing... would you want that thing on your ceiling! I didn't want to prod about too much and end up setting the bells off, but it looked like the end bi-metallic strip moving upwards was what happened when it was heated wasn't sure how it opened up. Interesting to note about the mercury switches inside, I can remember when I was a kid my dad having a couple of them on a shelf in the garage, he worked for a catering equipment manufacturer and they'd be fitted on the arm of the float valve of the water boilers in the 80s, somehow don't think that sort of design would be allowed these days incase it got broken!
