したことを特徴とする自動火災報知器。 A first terminal pin 6 made of copper is fixed to one end of a copper case 10, a second terminal pin 7 is fixed to the other end via an insulating member, and one end of this second terminal pin 7 is made to protrude inside the case 10. On the other hand, a temperature-sensitive pellet 13 made of a soluble substance is placed inside the case 10.
A spring 14 with one end in contact with the spring 14 is housed, and a movable contact 12 biased toward the first terminal pin 6 by an auxiliary spring 15 made of an insulating material is arranged in the case 10. A plurality of temperature fuses 5, which are configured to be able to slide along the inner surface and are biased by the spring 14 so as to come into contact with the second terminal pin 7, are arranged at predetermined positions in the building. temperature fuses are connected in series to a DC circuit through which a minute current flows, the outputs at both ends of the plurality of temperature fuses 5 are connected to a switching circuit 18 of the alarm device 17, and this switching circuit 18 is connected to the plurality of temperature fuses 5 in series. An automatic fire alarm system characterized in that the output signal is inverted due to fluctuations in the output between both ends of the fire alarm.
