1.0 Introduction
The Model R820 solar-powered flashing beacon increases the visibility of pedestrians using
uncontrolled crosswalks. A typical installation consists of two pairs of flashing beacons, each
mounted on poles at opposite ends of the crosswalk. Pedestrians activate the R820 solar
roadway lights by pressing a button installed on either pole. The two units communicate with each
other using radio signals. On each pair of lights, one light is flashing towards traffic approaching
the crosswalk from each direction. Coming from either direction, drivers will see two flashing
lights, one on each end of the crosswalk. When activated, drivers will see a “bouncing-ball effect”,
with lights flashing on alternate ends of the crosswalk. The R820 system can accommodate
additional beacons, either in the median, overhead, or in advance of the crosswalk.
Since the R820 operates entirely by solar power, connecting to grid power is unnecessary. In
addition, wireless communication between units means that the R820 requires no trenching of
cables across the roadway. The R820 solar-powered roadway light is designed to operate reliably
under all environmental conditions with no scheduled maintenance for up to 5 years.
WARNING: The R820 is a warning beacon and is intended to be used as a supplemental
emphasis to warning signs located at uncontrolled marked crosswalks, as specified in the
2003 Manual of Uniform Traffic Control Devices, Chapter 4K . It is not a traffic control
device. It is the responsibility of the pedestrian to ensure traffic has stopped before entering
the crosswalk; this is clearly noted on the information plate mounted with the activation
pushbutton. The R820 is only a supplement for an uncontrolled marked crossing.
WARNING: Exercise caution when handling the battery packs. They are capable of
generating enormous short-circuit currents. Remove all jewelry (bracelets, metal-strap
watches, rings) before attempting to handle or remove the battery packs.
