What is the minimum height a fire alarm strobe must be mounted?

The minimum height at which a fire alarm strobe must be mounted is generally established to ensure that it is clearly visible and effective in alerting occupants in various environments. A height of 80 inches provides a proper line of sight for individuals of varying heights, including those in wheelchairs or other mobility devices, ensuring accessibility and safety.

This height is aligned with the National Fire Protection Association (NFPA) code regulations, which set standards to maximize the effectiveness of fire alarm systems in alerting occupants during an emergency. Strobing lights must be positioned where they can be easily seen, especially in high-stress or low-visibility situations that accompany fires.

In this context, the other options suggest either lower or higher mounting heights, which do not meet the recommended regulations and could potentially impair the effectiveness of the strobe in alarm situations. Therefore, mounting at 80 inches ensures compliance with safety standards and provides optimal functionality.
