Abstract

PURPOSE:To confirm on the transmittor side the fact that information is received on the receiver, by outputting on-signal of a switch from the 1st terminal and by operating an alarm device in correspondence to a signal inputted from the 2nd terminal. CONSTITUTION:A push-button switch S is turned on and the output of a flip flop FF is set to high level. As a result, a pulse signal which is input from a terminal P is added to a counter CT through an AND gate AN1 and counted. The output of the 1st and 3rd bits of the counter CT is added to an AND gate AN4 through an AND gate AN3. While, high-level voltage output from a terminal 1a is added to the AND gate AN4 if a transmission line III and a feedback line V are normal. As a result, a pulse having a constant pulse width is outputted from the AND gate AN4 and light emitting diode illuminates for a constant time.
