Abstract

PURPOSE:To make it possible to increase the number of objectes to be monitored, by changing the transmission timing of a return signal to a main operation monitor panel. CONSTITUTION:The transmission signal from a main operation supervisory panel is inputted to a logic circuit 15 through a signal inversion control circuit part 30; and when address coincidence is discriminated, a control gate signal is outputted from a gate G1. This signal sets or resets a flip flop 39. Meanwhile, a 2-chnnel multiplexer 40 outputs Q and -Q outputs of the flip flop 39 to an I/O terminal slectively by closing or opening of a switch 41 of a signal direction selecting circuit part 31. That is, the phase of an input signal is selected by the state of the switch 41. Consequently, two terminal equipments having the same address are connected, and phases of input signals of them are made different from each other, and as the result, transmission timings of return signals of them are made different from each other to transmit monitoring data.
