Abstract
By pushing the registration switch of a main controller, a radio signal for requesting the transmission of a terminal-device ID number is transmitted (SP1, SP2). A wireless sensor sends back the terminal-device ID number (SP11, SP12), and the main controller stores the received terminal-device ID number in its storage unit and transmits a main-controller device ID number (SP4, SP5). The wireless sensor stores the main-controller device ID number in its storage unit. From then on, communications between devices whose device ID numbers have been registered are permitted.
