Abstract: There are provided: a first communication device; a second communication device that communicates wirelessly with the first communication device; and a state detector that outputs state data indicating a state of a predetermined installation place. The first communication device includes: a storage; and a data controller that selectively executes a transmitting operation to transmit the state data to the second communication device and a storing operation to store the state data in the storage. The second communication device includes a signal generator that generates a stop notification signal notifying that the second communication device in operation stops an operation, and stops the operation after transmitting the stop notification signal to the first communication device. The data controller executes the transmitting operation before the stop notification signal is transmitted from the second communication device, and executes the storing operation after the stop notification signal is transmitted from the second communication device.
