Sprinklers can cover up to 225 square feet in light-hazard environments; up to 130 square feet in ordinary-hazard environments; and up to 100 square feet in extra-hazard environments. The amount of water discharged is dependent on the spacing and density requirements in accordance with NFPA 13. When a municipal water supply is not available or impractical, the piping network may be designed to draw water from another source, which can be either open or closed.

The minimum 1" is typical; however, concealed, recessed, and flush sprinklers may be mounted less than 1" from the ceiling and shall be installed based on their listing. Because fire sprinklers are heat activated, sprinkler heads must be located high up on or near the ceiling. In short, fire sprinklers are expected to deliver more water while covering a smaller and smaller area as hazards increase. However, that lintel or soffit can't exceed 16 inches in width unless it's protected by a pendent head. behalf.
