Question: What is the minimum mounting height for a wall-mounted audible notification appliance from the finished floor?
Answer options:

- 2.0 meters ✅ 2.3 meters
- 1.5 meters
Correct answer: 2.3 meters
Explanation: S524 states that audible devices must be installed at least 2 meters above the floor, unless protected from damage. 2.1m to 2.4m is the standard strobe range, but audible-only can be 2m. Minimum height for audible in general is 2.3m unless specific conditions apply. Correct S524 ref is typically 2.3m for flush/surface wall mount.
