Consists of

With the above configuration, the master unit 21 or the slave unit 41 has the function of a remote transmitting device, and calls the master unit 21 or the slave unit 41 from outside via a telephone line, and transmits a predetermined DTMF signal. By sending, parent device 21
Alternatively, the slave unit 41 identifies the signal and
Alternatively, a remote control signal is output to 46. The remote controller adapter body 27 or 46 receives this and
Opening and closing control of 2 and 12 is performed. Thus, turning on of the electric device can be controlled from outside. By using the relay adapter 40 to transmit signals by light or sound waves, the configuration can be simplified and downsized as compared with the case of the master unit using radio waves. In addition, the relay adapter 40 is
