Problems solved by technology

[0003] During the use of the short-circuit alarm method of the above-mentioned non-recoverable linear temperature-sensing detector, because a short-circuit fault alarm and a short-circuit fire alarm occur on the linear temperature sensing element, a short-circuit point is shared at the same time, which is likely to cause misjudgment or leakage. Fire alarm, can not provide open circuit fault

Abstract

The invention relates to a single-temperature fault-alarming outputting line-type heat-sensing detector which can not be restored. The detector comprises a heat-sensing cable two ends of which are respectively connected with a resistance signal processing device and a terminal resistance whose value is optimized between 50omega-50Momega to form a resistance signal connection circuit. It is characterized by the two elastic metal connectors of the heat-sensing cable, in which one connector is coated with insulation material layer and the other is coated with semi-conductor material layer. The two connectors are intertwisted or wound together in a pitch optimized between 20mm-200mm. In the resistance signal processing device are set with three signal starting resistance values of resistance change quantity. The resistance signal processing device judges and outputs set-temperature alarming signals, short circuit fault signals and broken circuit fault signals.

Description

technical field [0001] The invention relates to a fire alarm device, which is a non-recoverable single-temperature alarm fault output linear temperature-sensing detector. technical background [0002] A short-circuit alarm method for a non-recoverable linear temperature-sensing detector in the prior art, application number ZL200610130417.5 is shown in Figure 1: including the stage where a short-circuit occurs on the linear temperature-sensing element; The stage of whether the detected electrical parameter (or sampling value) changes within the time; if the judgment result is that the electrical parameter (or sampling value) does not change, the conversion box sends a short-circuit fault alarm signal and performs a short-circuit fault alarm stage; If the judgment result is that the electrical parameter (or sampled value) changes, the conversion box will send out a short-circuit fire alarm signal when the electrical parameter (or sampled value) reaches the set alarm threshold ...
