When the transmitter 131 transmits a signal from at least one of the plurality of sensors 121 to 125, the transmitter 131 receives the signal, determines which sensor the received signal is from, and wirelessly receives a signal indicating an emergency situation. Send to 115. At this time, the transmitter 131 modulates and transmits a signal including information on an emergency to a high frequency signal, for example, a frequency shift keying (FSK) signal. The configuration of the transmitter 131 will be described in detail with reference to FIG. 2.

The remote controller 141 wirelessly controls the operation of the transmitter 131. The remote controllers 141 are assigned to one transmitting apparatus one by one, but if the frequency of use is unified, all the transmitting apparatuses 111a to 111n can be controlled by one remote controller 141.
