Before this past Saturday morning, if asked, I would have said "I don't think FM requires 1.4 anymore, especially if it is not a high risk occupancy". But before Friday afternoon I was not even aware of FM Data Sheet 3-0 HYDRAULICS OF FIRE PROTECTION SYSTEMS.
On page 21, for the Density/Demand Area Format, in a nutshell it says 1.2 for ceiling slopes less than or eq. to 5 degree (1 in 12 i think), and 1.4 for slopes greater than that! Friday I had been reading the product data of a sprinkler head that I had seen Advertised in a mag. (be careful if FM is not the only AHJ) and I saw the above 1.2/1.4 requirement. It was a freak coincidence to shortly realize that it had come from FM, not the manufacturer. Is any one aware of this? Am I just "seeing things" here? Is there more or less to it? thanks, Brad Casterline, NICET IV Fire Protection Division FSC, Inc.
