A new flashlight fire alarm has recently appeared in Copenhagen. It consists of a small cartridge filled with Bengal light composition and provided with a fuse which carries a small capsule of strong sulphuric acid. When the temperature of the room rises above the melting point of paraffine the sulphuric acid is liberated and ignites the fuse which in turn sets fire to the Bengal light. The device can be supplemented by a piece of fusible metal which in melting will establish an electric current and ring a bell.
