Abstract

A system includes a communication circuit provided in at least one of multiple devices that are connected to a control device in a predetermined connection relationship. The control device includes: a signal transmitter designating, as a destination, one of the devices provided with the communication circuit, based on the connection relationship, and transmitting a call signal to the device designated as the destination; a receiver circuit wirelessly receiving a recall signal, which is transmitted in response to the call signal; and a determination unit determining that the control device and the device designated as the destination are connected in the connection relationship when the receiver circuit receives the recall signal. The communication circuit wirelessly transmits the recall signal to the control device when the device provided with the communication circuit itself is designated as the destination and when the device provided with the communication circuit itself receives the call signal.
