Abstract: PROBLEM TO BE SOLVED: To extend the service life of a battery by sending a detected signal from a portable transmitter after receiving a feed signal from a detector so as to eliminate the need for transmission of the detected signal at all times thereby reducing the current consumption. SOLUTION: A detector D sends a feed signal f3 and the transmission of the feeding signal f3 and the reception of a detected signal f1 by a portable transmitter T are conducted at all times through the changeover of an antenna switch. In a transmission circuit of the detector D, a carrier oscillated by the oscillation circuit is frequency-modulated at an FM modulation circuit with a detector ID and the result is amplified by an FM amplifier circuit as a feeding signal f3 and the amplified modulation signal is sent from an antenna. In the portable transmitter T, an antenna SW1 is always thrown to the position of the receiver side, and when the oscillator T approaches the detector D, the antenna of the transmitter T receives the feeding signal f3 sent by the detector D.  When the feeding signal f3 is received, a voltage is induced in the antenna 13 and a filter 1 eliminates noise other than the feeding signal via an antenna switch.
