What is the maximum distance between visual notification appliances?

• A. 50 feet
• B. 150 feet
• C. 200 feet
• D. 100 feet

Answer: (D)

Visual notification appliances are placed so that every area an occupant might occupy is within the device’s visible coverage. The rule sets a maximum spacing of 100 feet to ensure a strobe is within sight along egress routes and in rooms, which is especially important for those who rely on visual cues. This limit helps prevent blind spots and guarantees that a visual alarm can be seen promptly as people move through corridors or larger spaces. Distances like 50 feet would be more restrictive than necessary, while 150 or 200 feet could leave some areas without a visible alarm. Therefore, the furthest distance allowed between visual notification appliances is 100 feet.
