APS Beacon & BBU


The APS Beacon provides a loud locator tone to the pedestrian from a second speaker location on or near the pedestrian display at the far end of the crosswalk during the pedestrian change interval.  The beacon is aimed toward the end of the first third of the crosswalk. The pedestrian is at the initiation point where they place a call of one second or longer at the push button, and the APS Beacon is located at the pedestrian destination point, 7-10 feet high per the MUTCD NPA, where it can broadcast a loud locator tone, up to 100 dBA to the final two-thirds of the crosswalk. during the pedestrian change interval.


    A full APS solution in a compact package and ready to install out of the box, the Guardian Mini utilizes existing mounting holes from an ADA push button.
