Abstract

PURPOSE:To reduce malfunction caused by mischief or a disturbance wave, by constituting an equipment so that a control code is changed at every constant period by a sending side, and a deciding code is changed over, corresponding to said operation, by a receiving side, too. CONSTITUTION:A control code which has been generated by a control code generator 1 is sent through a sending part 2 and an antenna 3. Its wave is caught by an antenna 5 of a receiving side, and the control code is demodulated by a receiving part 6. The control code is compared and discriminated with a code which has been generated by a code setting part 10, in a code discriminating circuit 7, and in case of coincidence, an output to operate a low frequency amplifying part 8 is generated, and when the low frequency amplifying part 8 is generated, an emergency information which has been detected by the receiving part 6 is heard from a speaker 9. In the sending side, a control code is changed over periodically by a code changeover part 4, and in the receiving side, too, a code corresponding to said code is set by the code setting part 10.
