Description
This powerpoint presentation begins by providing a brief overview of the Residential Fire Service Meter Task Group that wasformed three years ago by Standards Committee #380, toinvestigate residential fires sprinkler (RFS) metering issues. This Task Group isnow struggling over two basic issues:do RFS applications require new AWWA meter standardsprovisions; and if so, what technical requirements should beincluded? To gather further information on this subject, thistask group wrote an article in the CommitteeConnection section of the April 2008 JournalAWWA. This article asks for comments on three alternativepositions regarding RFS metering that include the following:the sprinkler supply branch should not be metered;the sprinkler supply branch should be metered with aconventional/standard water meter; and,the sprinkler supply branch should be metered withspecial meters, specifically designed for RFS applications(and requiring new meter standards provisions). Basic fire sprinkler installation requirements aregiven in National Fire Protection Association(NFPA) standards. General attributes of NFPA 13D systems are presented, NFPA 13D has a preferred arrangement for watersupply and plumbing – A-2-2(a). To promote the use of 13D systems, Building CodeAdministrators and municipalities have offeredincentives to reduce the net cost of RFSinstallations (a.k.a. trade-offs, trade-ups, designfreedoms, design alternatives). Actual RFS field experiences are presented for Scottsdale, Arizona and Prince George’s County, Maryland. Metering considerations in light of NFPA 13Drequirements and actual field experiences are provided.
