Reach range of pushbuttons Pushbuttons must be within accessible reach range of a level landing for use from a wheelchair and no higher than 42 inches measured from the landing. Pushbutton location Pushbuttons should be within reach from a level landing, within 5 feet of the crosswalk lines extended and within 10 feet of the curb. See specification information in Installation Specifications. Vibrotactile information Vibrotactile WALK information should be provided during the associated Walk interval by each APS equipped with a vibrating surface. If two pushbutton-integrated APS with vibrating surfaces are installed on the same pole, they may both vibrate during both walk intervals if they are not properly insulated from the pole and spaced apart from each other. Orientation of tactile arrows The tactile arrow must be oriented parallel to the direction of the crosswalk controlled by the pushbutton. Installer should check that arrow direction and pushbutton information message agree. APS have accidentally been installed with the message providing notification about the wrong street.
Speech messages When sound chips with the recorded speech message are part of the device or its control board, the installer must take care to install the proper device and control board in each location. top
