ADAAG Manual

Location and Signage

ADAAG does not specify where text telephones are to be located on a site or in a building (except in hospitals, airports, and transit stations). It is best to locate them along primary circulation routes and in central or prominent phone locations so they are easy to find. Since not all phones or banks are equipped with TTYs, signage is important. Signs are required at all phone banks without TTYs indicating the location of the nearest TTY; (if there are no other banks, directional signage is required at building entrances. Additional signage, such as on building maps, is helpful too. Signs labeling pay phones with TTYs is required as well, in part because integrated TTYs may not be easily identified. An international symbol as specified in 4.30.7 is used on all TTY signs. ADAAG does not specify sign size, or in the case directional signs, verbal content, but requires a light-on-dark or dark-on-light color contrast between the content and the background and a non-glare finish.
