1. , a kind of line-type heat detector that adopts the data fusion mode to report to the police, it comprises single line type temperature sensing element (1);

  • Be connected an end of linear temperature sensor (1), can be in real time the electrical quantity of linear temperature sensor be detected, and carry out the boxcar (3) of fire alarm according to the comparative result of the alarm threshold value of above-mentioned electric parameter measurement value and setting;

    With the electronic switch (2) that is connected linear temperature sensor (1) other end;

    Wherein linear temperature sensor (1) comprises two parallel detecting conductors (4,5) that are provided with and the parallel NTC characteristic barrier layer (6) that is arranged between the detecting conductor (4,5);

    It is characterized in that;

    at least one is the detecting conductor with ptc characteristics in the described detecting conductor (4,5).
