This assembly detail specifies the accessibility requirements for elevator interfaces, including hall call buttons and car control panels. Hall call buttons must be at least 1/8 inch raised and 3/4 inch tall, positioned at a maximum height of 48 inches. Jamb-mounted floor landing numbers must be at least 2 inches tall with 1/32 inch raised lettering, with a star symbol indicating the main exit floor. Car control panels require a minimum 3/4 inch control button diameter with 1/2 inch minimum character and symbol height and 3/8 inch minimum separation between buttons. The emergency stop button must feature a raised octagon symbol, while the 'X' within the symbol remains flush. Automatic door reopening devices are triggered by objects passing through detection lines A and B, which represent non-contact vertical sensing zones.
