This question relates to the problem that none of the residential fire sprinklers currently on the market are listed for slopes greater than 8:12, and NFPA 13D requires residential fire sprinklers.
Has anyone run across single family home projects with ceiling slopes greater than 8:12. What has been common practice for designing these sprinkler systems? I have seen AHJs requesting increasing the design area to 3 heads (50% increase). This helps in some repect, but the sprinklers are still being installed outside of their listing.
