Abstract

PURPOSE: To detect simply and accurately a short-circuited spot on a signal line connecting a main control panel and terminals by receiving a transmission output of a wireless transmitter on main control panel input side according to reception of signals from terminal side on a wireless receiver on terminal side.
CONSTITUTION: A main control panel M and a multitude of terminals T1, T2... are connected through a signal line L. When a signal from a signal generator 4 connected to the terminal T2 is received on a receiver 2 connected to an input side of the control panel M, a confirmatory signal is transmitted from a wireless transmitter 1, which is received on a wireless receiver 5 on the terminal T2 side, and a buzzer sounds. The buzzer does not sound where there occurs a short circuit between the terminal T2 and the control panel M, thus a short-circuited spot on the signal line can be detected simply and accurately.
