範囲第１項及び第２項記載の警報器。[Claims for Utility Model Registration] (1) In an alarm device that sets upper and lower limit values for the input current of the compressor drive motor and issues a signal when these values are exceeded, It is characterized by having a multiplier that automatically changes depending on the condensed gas pressure or its temperature, the evaporated gas pressure or its temperature, etc., and its purpose is to control the electric motor and the compressor driven by it. The goal is to always give appropriate warnings even for minor abnormalities. (2) A request for registration of a utility model characterized in that the motor has a multiplier whose upper limit value of input current representing the normal maximum load of the motor itself automatically changes depending on the winding temperature, input power frequency, etc. The alarm device described in item 1 within the scope of . (3) In an alarm device that sets upper and lower limit values for the input current of the compressor motor and issues a signal when the input current exceeds those limits, the signal is transmitted to multiple nearby Distinguishing the signals emitted from the motor,
The alarm device according to claims 1 and 2 of the utility model registration claim, characterized in that the alarm device transmits electromagnetic waves by changing different frequencies and the number of repetition times so as to be able to distinguish between upper limit values, upper limit values, and lower limit values. .
