Our Rectangular Rapid Flashing Beacon (RRFB) RRFBalerts drivers of pedestrians in a crosswalk in-real time. Installed on the sidewalk near the crosswalk’s entrance, RRFBs are an economical and easy-to-install pedestrian safety measure.

Pedestrians activate the system via ADA compliant push button devices or automatically via our Automatic Activation Pedestrian Detection Bollards. RRFB systems operate with AC power sources and are low voltage DC operated flashing safety systems. They are offered in wireless solar and hard wired, and are sold as a pair.

Our PCU RRFB system is capable of collecting directional statistics and detecting peak hours, daily, weekly and monthly patterns. This data helps to adjust traffic and parking regulations to improve pedestrians comfort and safety.

RRFBs can be used as a stand-alone pedestrian warning system and can also be upgraded to our Smart Crosswalk™ system which contains in-roadway warning lights (IRWL). Installers need only supply the 12VDC output from a flashing unit controller to the RRFB for operation.


MUTCD Authorized for Optional Use of Rectangular Rapid Flashing Beacons 

Application Notes:

Separate AC or DC input powered controller required. The RRFB may be powered by a separate (not shown) LightGuard Systems®, Inc. flashing unit controller (AC or Solar) sold separately.  The flashing output is user select-able for either one of two flashing sequence options (LRLRL or LLLRR) alerting motorists to the presence of the crosswalk.


Solar Powered Wireless RRFB System

Solar Wireless RRFB UnitThe Wireless RRFB is used at a crosswalk to alert motorists to the presence of pedestrians and are offered as a pair. Pedestrians activate the system via ADA compliant push button station devices. RRFBs will flash for the cross time duration setting.

Application Notes:

The wireless RRFB use FCC approved matched transceivers to securely communicate pedestrian activation from either cross walk 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 &/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 W-63 schoolhouse crossing sign available.

Our solar wireless RRFBs are installed on both sides of the crosswalk, and activated with either manual push button or our Automatic Activation Pedestrian Detection Bollard devices. RRFB systems can operate with AC power sources; they are low voltage DC operated flashing safety systems.
