Abstract: PURPOSE: To output location result data having a time difference by transmitting a location result output allowance signal a predetermined time after outputting the data to a hose system when a location result output request signal is received from a lower order device. CONSTITUTION: A fault location FL2 sets a terminal (a) to H if a terminal (c) is set to H (request signal is transmitted) from a fault location FL3 or if a fault occurs at a transmission line L and a fault point location result is obtained by the unit FL2 , and transmits a request signal to the fault location FL1 of a hose unit. That is, if there is a location output request at a lower order unit including itself, a request signal is transmitted to the host unit, and an allowance signal for receiving at a terminal (b) is waited from the fault location FL1 . If the signal is received (the terminal (b) is set to H), location result data is output to a telecontrol 1. After outputting, the signal is transmitted to the fault location FL3 .  In this case, the time of transmitting to the telecontrol 1 is an already set fixed time, and the signal is transmitted the fixed time after outputting. Thus, the result data with a time difference can be output.
