PROBLEM TO BE SOLVED: To appropriately perform event supporting processing by suppressing the time delay to a requisite minimum when an urgent event such as fire reporting to send early or fire restoration occurs during telegram transmission. SOLUTION: In occurrence of an event A, a transmission processing part of a radio sensor repeats, twice or more, telegram transmission A1-A3 for continuously transmitting the same telegram signal for a predetermined time T1 and telegram pause for pausing the telegram transmission for a predetermined time T2. When an urgent event B occurs during repetition of the telegram transmission A1 and the telegram pause based on the occurrence of the preceding event A by the transmission processing part, a transmission switching part repeats, once, the telegram transmission A1 and the telegram pause based on the preceding event A and pauses them, then switches them to the repetition of the telegram transmission B1, B2, etc. and the telegram pause based on the urgent event B.
