After installation, each SmartSensor Matrix unit will need to be integrated into the
traffic cabinet for power, surge, and communications. Pre- wired cabinet units
(PCUs) are available for sensor integration. As an example, this chapter will detail
integration of a Wavetronix stop bar detection system PCU panel that
accommodates four SmartSensor Matrix units (one for each stop bar of a common
four approach intersection).

The standard four-approach PCU back plate is sized 11 inches wide and 11.5 inches
high. Softcopy and hardcopy plans of the cabinet unit wiring are available for
maintenance personnel. All wiring in the on the PCU is done using stranded wires
with wire ferrules for screw terminal connections. The stranded wires are flexible
