Wall-mounted audible devices must be mounted so the top of the device is at least ___ below the ceiling and the top is at least ___ above the finished floor level.

• A. 2 inches, 90 inches
• B. 6 inches, 90 inches
• C. 12 inches, 84 inches
• D. 10 inches, 72 inches

Answer: (B)

The thing being tested is proper mounting height for wall‑mounted audible devices to ensure the sound is effective and stays protected from tampering. Mounting the top of the device at least six inches below the ceiling helps avoid acoustic dead spots and clearance issues near the ceiling, so the horn or siren projects sound cleanly into the room. Placing the top at least ninety inches above the finished floor keeps the device out of reach and above typical furniture and eye level, which aids durability, reduces tampering risk, and helps ensure consistent sound distribution throughout the space. Options with the top too close to the ceiling or too low above the floor would compromise audibility and practicality. So the best match is six inches below the ceiling and ninety inches above the floor.
