I see some worms peeking through the lid of the can. Is this going to spiral us down the EOR hole again or is this another hole occupied by sprinkler designers/contractors?

Based on the recently discussed conservative committee actions I would think that anything in the later editions of 13 should be allowed as an "alternate arrangement". Say something in 2002 edition that was later proved to be wrong through full scale testing. Would you force a licensed contractor to install it wrong because the AHJ hasn't adopted the standard with the new data with the corrections? Or as a licensed contractor would you knowingly install something that has been proven to be wrong by today's standards because it was okay in the 2002 editionRon F -----Original Message----- From: Sprinklerforum [mailto:[email protected]] On Behalf Of Mark A.

Therefore, we cannot accept those 'clarifications.' WE may KNOW that the changes won't affect the future code revisions; but the AHJ doesn't know and most times won't take the chance. Mark A.

We have an ECHSW above the door in a room. On the opposite wall is a window and sill that does not create an additional floor area. There is a built in cabinet that partially obstructs the window sill and creates a shadow of 2 sq.ft. between the cabinet and the window over the window sill. We informed the AHJ that per NFPA 13 (2007) 8.5.3.2.4 sprinklers are spaced to walls and not windows if they do not create additional floor area. We also pointed to NFPA 13 (2013) 8.1.1(3) & A.8.1.1(3) which indicate shadow areas are acceptable so long as the other obstruction guidelines are followed. The AHJ stated they cannot accept the newer standard clarifications on this issue. Is there something I am missing in NFPA 13 (2002) that states this design is acceptable?
