36 CFR Parts 1190 and 1191 ADA and ABA Accessibility Guidelines - Preamble (Discussion of Comments and Changes)

Section 407.3.4 specifies door and signal timing. This provision helps ensure that elevator doors remain open long enough for persons with disabilities to travel from call buttons to the responding car and is based on a travel speed of 1 ½ feet per second. Destination-oriented elevators may have call buttons located outside elevator landing areas and have enhanced programming features for the response time of cars. In recognition of this, the Board has included in the final rule an exception from the door and signal timing requirements for destination-oriented elevators (407.3.4, Exception 2).
