Problems solved by technology

It can be seen that the linear temperature-sensing fire detectors in the prior art that use a single linear temperature sensing element and detect a single electrical parameter of the linear temperature sensing element cannot accurately measure the temperature of the heated part of the temperature sensing element. The size or the rate of change of temperature, so it is impossible to give an accurate alarm in the event of a fire, and it is also difficult to pass the two tests of the action test and the non-action test of the line fire detector according to the technical standards of the line fire detector
