Portable Traffic Signal Support

Basic programming manuals for units with 1.0 and 2.0 controllers can be found in the MANUALS section below. Please contact Street Smart support by phone for a more detailed assistance on programming signals for your specific project.

All Horizon signals are designed to communicate by radio at a distance of up to 1 mile with a clear line of sight.

Doppler radars are designed to be “plug and play.” Dopplers are mounted to a bracket fixed to the bottom of the lower signal head and plugged into the black plug on the white junction box located on the signal mast near the lower signal head. To utilize a doppler for green extension time all you need to do is mount the doppler and while programming create a green time as well as an extension time and the doppler will automatically use that extension while detecting traffic. The dopplers can also be used to activate a green cycle when traffic is detected. To do this you’ll need to program the signals to “rest in red YES.” With rest in red activated, the signals will stay red until a doppler detects a vehicle and then cycle to green.

Horizon SQ3 portable traffic signals are designed to run autonomously year round if the solar panels are fully expanded, free of any sun obstructions, tilted to face due south, and kept clean. If you are having low battery issues with a unit contact Street Smart Support for additional assistance.
