Campbell Wave Pedestrian Station

Guardian pedestrian system is available in touch-free options, increasing pedestrian safety by placing a call with the wave of a hand. 


Guardian is an independent 4-Wire Accessible Pedestrian Signal. A four-conductor cable connects the Signal Power Interface (SPI) in the pedestrian signal head to the Guardian station. The housing is machined from a solid billet of 6061 T6 AL and is vandal resistant. The push button is ADA compliant and is designed to withstand extreme conditions. The Guardian provides information and audible indications required by the MUTCD and TAC making the intersection accessible for all pedestrians. Bump and Wave options allow pedestrians a non-contact actuation solution. Guardian Wave™ is equipped with a non-contact actuation sensor. Pedestrians place a call by waving a hand in front of the Wave Icon near the physical actuator. No exclusivity or proprietary apps, the solution in available to 100% of all pedestrians. Guardian Bluetooth ® Bump™ add-on option utilizes the Bluetooth module for noncontact actuation functionality. The Bump allows a pedestrian to make a call by placing their NFC enabled smart phone near the Guardian Bluetooth module. Bump™ utilizes the PedCross app which is an agency controlled supplement.
