 Cautions for Connection of Dual Input Signals
• Connect the switch (contact) that turns the dual signals ON and OFF
simultaneously.
If the timing that turns the two signals ON and OFF is not right, a disagreement alarm
occurs. Refer to the figure below.
• Do not connect two signals to the same contact point.
Since the power supply for each signal is reversed, it will short-circuit if the signals are
connected to the same contact point.
