Wall-mounted strobes must be mounted between ___ and ___ above the finished floor level.

Wall-mounted strobes must be mounted between ___ and ___ above the finished floor level.

• A. 72 inches, 84 inches
• B. 84 inches, 90 inches
• C. 78 inches, 102 inches
• D. 80 inches, 96 inches

Answer: (D)

Visual alarm devices must be placed where they’re clearly visible to all occupants, including those who are seated or in wheelchairs. The standard specifies a specific height window for wall-mounted strobes: the center of the device should be between 80 inches and 96 inches above the finished floor. This range ensures the strobes are high enough to be seen over obstacles but not so high that they’re out of the line of sight for most people during an alarm. Among the given options, 80 inches to 96 inches matches this required range. Heights below 80 inches can be blocked by furniture or reach limitations, while heights above 96 inches reduce visibility for some occupants. A range like 84-90 inches sits inside the window but does not reflect the mandated limits, whereas 78-102 inches strays outside the allowed bounds on both ends.
