Rectangular Rapid Flashing Beacon (RRFB)

Rectangular Rapid Flashing Beacon (RRFB)

The RRFB is an economical, easy-to-install pedestrian safety measure that increases motorist yielding. The LightGuard Systems RRFB uses high-intensity LEDs (light-emitting diodes) to alert drivers of pedestrians in a crosswalk in real-time. It flashes at a highly visible MUTCD approved on/off rate that demands motorists’ attention.

Pedestrians activate the RRFB system using an ADA compliant push button device and/or passive pedestrian detection bollard sensors. The RRFB is a stand-alone pedestrian warning system that is commonly paired with static LED warning signs and is also compatible with our in-roadway warning lights (IRWL). System options: solar wireless; solar and AC power. (The Solar and AC PCU is capable of collecting directional statistics and detecting peak hours, daily, weekly and monthly patterns.)

RRFB increases driver yielding while improving visibility in locations such as:

  • Urban mid-block crosswalks
  • School crossings
  • Intersections with through lanes on major legs
  • Multi-lane crosswalks
  • Greenways
  • Trail crossings
  • Public parking garages
  • Corporate campuses

Application Notes:

The wireless RRFB use FCC approved matched transceivers to securely communicate pedestrian activation from either crosswalk entrance up to 250 ft. (75m) apart and is designed to support one RRFB up to 500 daily activations (30 sec each) for 7 days without requiring battery recharge.  Additional solar capacity (solar panel and/or battery) can be upgraded based on usage requirements.

The controllers and transceivers are factory installed, assembled into a lockable NEMA 4 cabinet. Installers need only connect the battery, solar panel, RRFB-F and push button to the enclosure mounted behind the static W11-2 sign located at each crosswalk entrance. Optional static S1-1 schoolhouse crossing sign available.
