Residential Sprinklers and Steep Slopes
Residential Sprinklers and Steep Slopes
(OP)
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.
