Withdrawn Technical Assistance: Common ADA Errors and Omissions in New Construction and Alterations

Visual Alarms

Error/Omission:

No visual alarms are provided although an audible alarm system is installed.

Result:

People who are deaf have no way of knowing that a building emergency has been declared while others who can hear are alerted by the audible alarm. This is especially true of toilet rooms, and study carrel areas where occupants cannot observe others leaving the facility.

Requirement:

4.1.3(14) If emergency warning systems are provided, then they shall include both audible alarms and visual alarms complying with 4.28. Sleeping accommodations required to comply with 9.3 shall have an alarm system complying with 4.28. Emergency warning systems in medical care facilities may be modified to suit standard health care alarm design practice.

4.28.1 General. Alarm systems required to be accessible by 4.1 shall comply with 4.28. At a minimum, visual signal appliances shall be provided in buildings and facilities in each of the following areas: restrooms and any other general usage areas (e.g., meeting rooms), hallways, lobbies, and any other area for common use.
