An office space with 10 ft (3 m) high ceilings is designated as a Light...

NFPA 13 allows for a reduction in the design area for quick-response sprinklers under certain conditions, such as in light hazard occupancies with ceilings not exceeding 12 ft in height. A reduction to 1,100 ft² is consistent with the allowance for using quick-response sprinklers to cover a smaller area more effectively due to their faster activation in fire scenarios.
