Which unit is used for spacing measurements of smoke detectors on ceilings in these guidelines?

• A. Meters
• B. Centimeters
• C. Inches
• D. Yards

Answer: (A)

Spacing on ceilings is specified in meters. This aligns with the metric standard used in the guidelines, making detector placement clear and scalable across different buildings and ceiling heights. Using meters keeps documentation consistent and easy to interpret; if you prefer imperial units, you can convert—1 meter is about 3.28 feet. Centimeters would be too granular for typical room-scale spacing, inches would clash with the metric standard, and yards would be impractically large for most ceiling placements, so meters is the appropriate unit.
