Each radar sensor requires a power and a network connection. The power and network connections run from the sensor to a local junction box (e.g. at the base of a post) where the power supply is situated. Remember to ensure that the maximum cable lengths remain within the capability of the selected cabling and infrastructure.

CIR wiring detail

The cabling requirements for the radar sensor are shown below.


IMPORTANT: The Ethernet protective cover must always be fitted if the Ethernet cable is not in place to ensure the integrity of the unit.

To connect power and network

  1. Remove the protective cap from the Ethernet connector and attach the RJ45 plug. Ensure that the weatherproof shroud on the Ethernet connector is secure.
  2. Attach the 24V DC plug to the connector (by pushing it fully on and turning clockwise to lock).
  3. Attach a suitable earth cable to the earthing point (requires an M5 bolt).
  4. Ensure that the power and Ethernet cables are securely connected into a suitable junction box that has a suitable 24V DC power supply installed.
    Note: The radar typically draws a continuous 800m A, but when the internal heater is active, this rises to approximately 2.2A. Ensure that the Power supply cabling is correctly terminated - see Appendix A.
  5. Ensure that the junction box has an Ethernet cable/fibre optic running to the infrastructure network switch.
  6. When power is applied, ensure that the radar begins rotating - you can easily hear this, although it takes approximately 10 seconds for the radar to start rotating – in cold conditions this could be longer.
