The Audible Beacon Device (ABD) was designed to assist visually impaired pedestrians at intersections. It functions as an add-on for Accessible Pedestrian Signals (APS) by providing distinct audible guidance during crosswalk navigation. The device emits a loud, percussive locator tone from an auxiliary speaker positioned at the destination end of the crosswalk, helping pedestrians maintain their trajectory in the final two-thirds of the crosswalk during the pedestrian change interval. Pedestrians can activate the ABD’s destination beaconing feature. through an extended press feature (holding for one second or longer) at an APS when the feature is turned on through PedConnex®.
The ABD is mounted either on the pedestrian signal head or a pole at the destination end of the crosswalk or to a pole at a height of 7-10 feet to meet MUTCD regulations. Its flexible design and trunnion bracket allow for easy positioning at the intersection ensuring audible signals reach all users throughout the crossing. In addition to functioning as an APS add-on, the ABD can also function as an audible information device when paired with 4EVR® Speech, RRFBs, or other passive detection devices, to broadcast messages at markedly louder volumes than the device alone. It features specific volume settings tailored for day and night, ensuring sound is delivered precisely when and where needed. The ABD comes ready to install but is fully customizable, and can be programmed with MUTCD-required messages, or any other custom messages that fit its application.
