To provide a wireless system in which a plurality of wireless receivers can perform the same notification processing upon receiving calls from wireless transmitters regardless of an installation environment of each receiver or a state of propagation property of a wireless signal.
A wireless receiver 1 or 1' is connected to another wireless receiver 1 or 1' with each other, and one receiver 1 or 1' is set in a wireless signal receiving mode, and the other receiver 1 or 1' is set in a wireless signal non-receiving mode. When a wireless signal is outputted from any of wireless transmitters 5A, the receiver 1 or 1' in a wireless signal receiving mode receives this to perform a prescribed notification processing, and transmits data registered corresponding to the transmitter 5A to the other receiver 1 or 1'. Upon receiving the data from the receiver 1 or 1' in a wireless signal receiving mode, the other receiver 1 or 1' performs the same notification processing as that of this receiver 1 or 1'.
