Problems solved by technology

The disadvantage of this detector is: the alarm temperature of the detector is related to factors such as the heating length, heating temperature, ambient temperature and service length of the temperature sensing cable, and the fire alarm temperature cannot be correctly judged. The accuracy and reliability of the detector alarm temperature are relatively low. Low

Abstract

The invention relates to a fire detector and an alarming method used for a parallel one-way digital temperature sensor, and the detector can be used as a linear fixed temperature fire detector, a differential fire detector and adifferential-fixed temperature fire detector. The detector has the functions of judging fire alarm and alarming for failures of short circuit, open circuit and power-off, and the detector can judge the position of the fire alarm along the circuit to be characterized in that the fire alarm positioning is accurate and the detector can be used repeatedly. The fire detector of the parallel one-way digital temperature sensor is formed by connecting an electrical signal measuring device with a temperature sensing cable which is composed of the one-way digital temperature sensor, a connecting conductor, an insulation layer, a filling layer and an outer jacket layer.
