FIRE ALARM WITH FUSE STATER

The utility model relates to a novel fire danger alarm starter for detecting fire danger. The utility model contacts the environment directly by an alarm alloy fusible chip selected by the standard of 50 DEG C-190 DEG C melting temperature. When fire danger temperature rises, the fusible chip melts to the liquid state from the solid state, a limit jacket tube is out of control and is pushed out of a metal shell round hole by the pressure of a compression spring acting on a pressure column, a float electrode on the pressure column is contacted with a fixed electrode on a fixed insulation plate, and a power supply conducting wire is communicated with an alarm power supply to rapidly start an electric bell and other audible and visual alarms or an automatic fire extinguisher to send out a fire danger alarm. The utility model has the advantages of simple structure, rapid alarm, and low equipment cost.
