What is the maximum separation allowed between visible notification appliances?

The maximum separation allowed between visible notification appliances is correctly noted to be 100 feet. This distance is based on guidelines established by the National Fire Protection Association (NFPA) and applicable local codes to ensure effective notification in the event of an emergency.

The rationale behind this specific measurement is to ensure that these appliances—such as strobe lights or visual alarms—are positioned close enough so that all occupants within the area are able to see them and become aware of an emergency situation. This distance helps to ensure that the visual warning is not only available but also effective for individuals who may have hearing impairments, thus enhancing safety for all building occupants.

Visibility is crucial, especially in larger spaces or areas with high ambient lighting, thereby necessitating a standardized approach to the arrangement of these appliances. If the separation exceeds 100 feet, certain individuals might not see the notifications, which could compromise their safety during critical situations.
