Compliance  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.  The RRFB can be used as a standalone warning system or upgraded at any time with LightGuard Systems®, Inc. In Roadway Warning Lights (IRWL).  Installers need only supply the 12VDC output from a flashing unit controller to the RRFB for operation.

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

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.

Solar wireless RRFB units are installed on either side of the crosswalk activated with manual push button (automatic activation available) devices that allows pedestrians to energize the beacons prior to crossing. These RRFB systems can operate with AC power sources; they are low voltage DC operated flashing safety systems.
