The Usability Standard (Voluntary Compliance Agreement) allows an equivalent alternate for elevators in existing buildings. Where an indicator panel for car position is not provided, lights can be mounted on the outside of the car and a view panel can be provided in the car and hoistway doors so that people waiting in lobbies can see the car arriving. |

The point of this rule is to avoid indented buttons. Such buttons can be difficult for people with limitations of hand movement to activate. |

Few NYCHA buildings would have indicator lights. The VCA Usability Standard allows vision panels in the car and hoistway doors as an alternative. |

The UFAS Checklist requires a single sound for the up direction and a double sound for the down direction. However, this is not required by the actual UFAS text. In NYCHA elevators, a gong is used for the up direction and a buzzer for the down direction. |
