When a fire broke out, the critical fire alarm system did not work at all due to a power outage or other electrical failure, resulting in a huge fire and the loss of many precious lives.Furthermore, the sensitivity of the fire alarm system itself has decreased over the years. It got better, and as a result, there were more false alarms,
There have been cases where building managers intentionally turned off the power to fire alarms, and when a fire broke out, the alarms did not work at all, leading to serious problems.

When this happens, the solid electrolyte, the anode active material, and the cathode active material generate electric power, and the temperature detection section is activated as a battery, and the above-mentioned alarm section is activated by this electric power. With this configuration, there is no need to worry about false alarms, there is no need to replace the battery, and it is small and inexpensive, so it can be applied to small-scale buildings and ordinary homes.

Among them, a combination of Na as the cathode active material 12 and Na5GdSi40i2 as the solid electrolyte 13 is preferred.

'tr(7)Na5GdSi4012, anode active material 11
Layers of graphite felt impregnated with sulfur are sequentially provided inside the gasket 14, and a top lid 15 made of copper is further applied.
The temperature sensing portion 17 was created by attaching and sealing under pressure. After that, the temperature detection part 17 was taken out from the dry box, and the fluororesin heat insulating material 18 with the electrode attached was removed.
In addition, a piezoelectric buzzer was attached to the upper part of the heat insulating material 18.

When the hot air current was applied to it, it issued a hunting report in about 5 seconds on average, exactly the same as before preservation.

であれば省略できる。As described above, the fire alarm according to the present invention does not require external power, and therefore can issue a fire alarm regardless of power outage or power outage. Since the battery function is obtained only when a fire is detected, there is no need to replace the dry battery, and maintenance is easy. Moreover, it can be made cheaply. Conventional bimetallic temperature sensing parts are wrapped in a protective material to prevent the contacts from getting dirty or deteriorating, resulting in lower sensitivity, but in this invention, the temperature sensing part is brought into direct contact with the heat. This results in high sensitivity. Note that the heat insulation 18 protects the alarm section 19 from heat, and can be omitted if the alarm section 19 is resistant to heat.
