If a lightning or strong lightning is detected in any of the slave stations, a lightning surge request is polled and output to all master stations. The polling means that the central office 3 sequentially transmits lightning surge frequency requests to all the master stations 2 and receives lightning surge frequency data. Each master station 2 stores a lightning surge detection signal from each lightning surge sensor 6, so that upon receiving a lightning surge request from the central office 3, the integrated lightning surge counter value is returned.
