When the LM10 contact inputs are connected to the remote devices for the input signal via long cables, induced voltages may be present at the input terminal of LM10 relay. The contact input status could be detected as closed if the induced voltages are greater than 33V. Under these situations it is recomonded to use interposing relay or to connect a resistor across the LM10 contact input terminal and ground to provide path for the induced voltages to the ground.
