| 产品规格 | 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. |
| 中文汉化 | 331000 固定温度点式火灾探测器，65°C -----描述-----：点型感温探测器安装在裸露的天花板表面或靠近天花板的墙壁上；当两种热膨胀系数不同的金属片贴合在一起并受热时，由于膨胀差异会导致金属片向膨胀率较低的一侧弯曲，从而闭合原本断开的电路；该固定温度型火灾探测器的机制是在环境温度上升速率超过预设值时触发火警报警。 |
