What is the maximum travel distance for visual notification devices in a hallway?

The maximum travel distance for visual notification devices in a hallway is established to ensure effective alerting for individuals who may be hearing impaired or in situations where auditory alarms may not be effective. The standard distance of 100 feet allows for an adequate level of visibility to ensure that occupants can see the notification devices, such as strobe lights, from a safe distance while evacuating or responding to an emergency.

This distance is based on safety requirements to reduce the risk of confusion during emergencies, where clear visual cues are essential for guiding people towards safety. Other options propose distances that either exceed commonly recognized safety guidelines or fall short of effectively ensuring that occupants under those conditions can receive visual notifications in a timely manner.
