The invention discloses a linear temperature sensitive fire detector. The linear temperature sensing element and the main switch are respectively connected with the line type temperature sensing element at both ends of the box and the auxiliary switch box; or comprises two parallel arranged linear temperature sensing element is connected, in which the primary conversion of a linear temperature sensing element at one end of the box and connected to the conversion of another linear temperature sensing element at the other end of the box. The linear temperature sensing fire detector is the use of the two conversion are located in a linear temperature sensing element at both ends of the box to detect the linear temperature sensing element is connected with a detection section of the fire alarm and alarm data respectively, so that even if the linear temperature sensor circuit failure element, it will not cause false fire problem therefore, can improve the reliability of the alarm of the linear temperature sensing fire detector.
