Product Usage Instructions

• Wiring Guide
  • When wiring the Guardian/Guardian Wave, follow the instructions below:
  • Ensure that the input voltage matches the requirements of your intersection.
  • Use 120VAC for 120VAC intersections and 48VDC for 48VDC intersections.
  • Connect the power supply to the pedestrian signal head SPI.
  • Use the blue wire for the +12VDC terminal, the white wire for the Walk terminal, and the orange wire for the Don’t Walk terminal.
  • Connect the blue wire to the Walk terminal and the white wire to the Neutral terminal.
  • Connect the -GND terminal to Terminal 3.
  • Connect Terminal 2 (S2 W) to the Walk terminal.
  • Connect Terminal 1 (S1 DW) to the Don’t Walk terminal.
  • Ensure that the SPI is not set on the bottom of the Pedestrian Signal Head.
  • The terminals of the SPI must be connected to the same terminals on the Base Station.
• Field Wires
  • The Guardian/Guardian Wave utilizes the existing field wires from the cabinet to pedestrian push buttons to place calls.
  • The field wires are not polarity-dependent and are only required for intersections.
  • Note: For new intersection installations, PedSafety recommends using IMSA 14-gauge loop detector wire in the absence of city or other local specifications.
• Warranty Note
  • The warranty for the Guardian/Guardian Wave is void if the Guardian is installed upside down.
• Additional Resources
  • For complete documentation and further installation guidance, please visit the PedSafetywebsite and refer to the PedConnex Utility Manual, pages 10-11.

• FAQ
  • Q: What are the input voltage options for the Guardian/Guardian Wave?
  • A: The Guardian/Guardian Wave supports either 120VAC or 48VDC input voltage.
  • Q: Can I use the same SPI for both 120VAC and 48VDC intersections?
  • A: No, 48VDC intersections require a different SPI than 120VAC intersections.
  • Q: Are field wires required for all installations?
  • A: No, field wires are only required for intersections.
