(d). Pedestrian Detection.
follows:
• General . Furnish a tamper and weatherproof assembly with pushbutton contacts, entirely insulated from the housing and buttons. Use a pushbutton with 2-inch diameter +/- 0.1-inch, audio signal actuation confirmation, Americans with Disabilities Act ( ADA) compliant, 303 or 316 stainless steel non- moving pushbutton and a maximum force of 5 pounds. Furnish sign and mounting assembly as indicated. Conform to the regulations for the sign legend and as specified in Section 1103.04 for the fabrication. Use stainless steel tamper resistant hardware to mount the pushbutton assembly.
• Housing. Die-cast aluminum alloy housing, with a curved back or a flat back as required to conform to the mounting surface. Powder coat the assembly highway yell
