Wiring Inputs and Outputs
Wiring Variable Resistance Analog Inputs
Variable resistance analog inputs include 10K thermistors, resistance temperature detectors (RTD),
and setpoint thumbwheels on zone sensors. To wire a variable resistance analog input:
1. Connect the shield to a common terminal at the terminal board and tape it back at the input
device.
2. Connect the signal wire to an available input terminal.
3. Use the Tracer TU service tool to configure the analog input that references the corresponding
hardware termination.
