What is the minimum height, in inches, for the tops of wall mounted audible appliances above the finished floor?

• A. 80
• B. 72
• C. 96
• D. 90

Answer: (D)

The height is set so that wall-mounted audible devices are high enough to be out of reach and above typical obstructions, while still projecting sound clearly throughout the space. The minimum tops-of-assembly height for these audible alarms is 90 inches above the finished floor. Placing them lower risks tampering and obstruction by furniture, whereas this 90-inch height strikes a practical balance between accessibility for maintenance and an unobstructed audible path. Heights lower than this are generally considered less effective, while going higher than 90 inches isn’t required unless specific conditions demand it.
