This powerpoint presentation begins by providing a brief overview of the Residential Fire Service Meter Task Group that was
formed three years ago by Standards Committee #380, to
investigate residential fires sprinkler (RFS) metering issues. This Task Group is
now struggling over two basic issues:
do RFS applications require new AWWA meter standards
provisions;
and if so, what technical requirements should be
included? To gather further information on this subject, this
task group wrote an article in the Committee
Connection section of the April 2008 Journal
AWWA. This article asks for comments on three alternative
positions regarding RFS metering that include the following:
the sprinkler supply branch should not be metered;
the sprinkler supply branch should be metered with a
conventional/standard water meter; and,
the sprinkler supply branch should be metered with
special meters, specifically designed for RFS applications
(and requiring new meter standards provisions). Basic fire sprinkler installation requirements are
given in National Fire Protection Association
(NFPA) standards. General attributes of NFPA 13D systems are presented, NFPA 13D has a preferred arrangement for water
supply and plumbing - A-2-2(a). To promote the use of 13D systems, Building Code
Administrators and municipalities have offered
incentives to reduce the net cost of RFS
installations (a.k.a. trade-offs, trade-ups, design
freedoms, design alternatives). Actual RFS field experiences are presented for Scottsdale, Arizona and Prince George's County, Maryland. Metering considerations in light of NFPA 13D
requirements and actual field experiences are provided.
