desc(描述)	Spot Heat Detectors are mounted on exposed ceiling surfaces or on a sidewall near the ceiling. When two metals with different coefficients of thermal expansion are bonded together and then heated, differential expansion causes bending or flexing toward the metal having the lower expansion rate. This action closes a normally open circuit. The mechanism of this fixed temperature type fire detector triggers the fire alarm, when the temperature rises at a rate exceeding a predetermined value.
cdesc(自动翻译)	331000 固定温度，65度热敏探测器。点型热探测器安装在裸露的天花板表面或靠近天花板的侧壁上。当两种具有不同热膨胀系数的金属结合并加热时，它们的膨胀差异会导致弯曲或向膨胀率较低的金属弯曲。这一动作会使通常打开的电路闭合。这种固定温度类型的火警探测器的工作原理是，当温度上升超过预设值时，会触发火警报警。
