As shown in FIG. 1 and FIG. 2, the present invention provides a transmitter 112 for transmitting a detection signal output from a plurality of sensors 111 for detecting a dangerous element in a home, and the air from the transmitter 112. It consists of a radiotelephone 113 for receiving and processing the radio waves propagated by.

The transmitter 112 may configure a plurality of transmitters (see FIG. 1) having individual bands to propagate detection signals from the plurality of detection sensors 111 to the air, and a detection sensor therein. The transmission on / off circuit section 112a is connected to an output side terminal of the output terminal, and outputs transmission information. An encoder 112b and a mixer section 112d are output to the output terminal of the transmission on / off circuit section 112a. Is coupled, and after mixing with the oscillation frequency from oscillator (OSC) 112c, it is configured to propagate into the air via amplifier 112e.
