Based on the unique floor plan of the home you’re building, the sprinkler designer determines the piping design and the appropriate number, type and layout of sprinklers along the piping.
Since sprinklers cover a minimum 12 x 12 foot area, while extended coverage sprinklers can cover up to a 20 X 20 foot area, in many rooms you’ll have a single sprinkler. Larger areas will be protected by additional sprinklers or special extended coverage sprinklers. For example, in a typical unfinished basement, three pendent sprinklers would be used to protect the far sides of the area and near the center stairway.
The NFPA 13D standard permits positioning sprinklers in basements to anticipate future ceiling finishing – a flexibility selling point for your buyers who are thinking ahead. If you finish the basement, concealed sprinklers can be used immediately.
When you get up into the finished areas of the home, concealed sprinklers can be used in the ceilings. Wall-mounted, semi-recessed sprinklers are used when you want to avoid placing pipes in an unfinished attic.
