External Sensor
Power to the external sensor is provided from the EIO4 card and must be grounded through the EIO4 card as
indicated in the diagram below. A pair of "sensor" and "common" lines are connected to the EIO4 card for each
external sensor. The PBX detects input from the sensor when the signal is under 100
W
