器に、所定温度に達したときに火災検出部を作動状態と
する予め記憶した形状に変位する形状記憶金属を設け、
作動試験時に該形状記憶金属の両端に電源を供給し、該
電源供給で流れる電流による自己発熱で前記形状記憶金
属を所定温度以上に加熱する作動試験用の信号線を引出
したことを特徴とする火災感知器の作動試験装置。A fire detector that detects changes in surrounding physical phenomena due to fire is provided with a shape memory metal that displaces into a pre-memorized shape that activates the fire detection part when a predetermined temperature is reached.
A signal line for the operation test is drawn out, which supplies power to both ends of the shape memory metal during the operation test, and heats the shape memory metal to a predetermined temperature or higher by self-heating due to the current flowing through the power supply. Fire detector operation test equipment.
