• A. 6
• B. 12
• C. 24
• D. 48

Answer: (B)

Spare sprinklers are kept on site so you can quickly replace a head during maintenance without interrupting the system. For protected facilities with 300 to 1000 sprinklers, no fewer than twelve spares provide a practical buffer to handle multiple replacements or repairs without delaying service. The spares should match the installed sprinkler type and temperature rating and be stored in a dry, accessible location with clear labeling. Six might be too few for this size, while twenty-four or forty-eight would be more than usually needed for this range unless maintenance needs are exceptionally high.
