What is the maximum mounting height for audible notification appliances according to NFPA 72?

Explanation:
NFPA 72 specifies a maximum mounting height of 90 inches (7 ft 6 in) above the finished floor for audible notification appliances. This keeps the sound energy at a practical height for occupants so the alarm is audible across most rooms, providing reliable coverage. If a space has taller ceilings or needs broader coverage, the code calls for additional devices or higher-output units rather than mounting devices higher than this limit.
