ABSTRACT:
A transmitter comprises a signaling history information transmission unit. After the transmitter generates a detection signal, the signaling history information transmission unit sends corresponding signaling history information to a regular signal transmission unit. From this regular signal transmission unit, the signaling history information and a regular signal are transmitted to a receiver. The signaling history information contains a count value which is updated at every transmission of the information. Even if the transmitter generates a detection signal during a communication failure, the receiver can identify a time when the transmitter generated the detection signal, based on a received count value.
