Review of Fire Sprinklers 501 – Residential Fire Sprinkler Systems for One- and Two-Family Dwellings: Part 1 - Design and Installation Concepts

One Hour and 40 Minutes –3 Audio parts
CEUs = .15 / CPDs = 1.5 (CEUs/CPDs are OPTIONAL)

This seminar, Part 1 of CLSE’s program on Plan Review and Acceptance of Residential Fire Sprinkler Systems designed in accordance with NFPA 13D, describes: the history of the NFPA 13D standard, and how it differs from NFPA 13 and NFPA 13R; Exceptions allowed by NFPA 13D in certain circumstances; Water supply requirements and how they are determined and evaluated; Residential sprinkler spacing and location; Residential sprinkler coverage areas, temperature ratings, and obstructions to discharge; Applicable pipe and fittings; Multipurpose and Stand-alone piping systems; and Concepts and considerations used in residential system hydraulic calculations. This is meant as a prerequisite to Fire Sprinklers 502.

On completion of this program, the attendee should be able to:

  • Describe the history of the NFPA 13D Standard and how it differs from NFPA 13 and NPFA 13R
  • Identify the exceptions in NPFA 13D that allow certain areas of a residence to be excluded from sprinkler protection
  • Describe the history of the NFPA 13D standard and how it differs from NFPA 13 and NPFA 13R
  • Identify acceptable water supplies and the water supply requirements for an NFPA 13D system
  • Calculate the gain or loss in pressure due to changes in elevation
  • Discuss coverage areas, temperature ratings and maximum spacing for residential sprinklers
  • Determine required pressure and flow for residential sprinklers at various spacings
  • Identify obstructions to discharge and sloped ceiling limitations in residential occupancies
  • Calculate the flow from various K-factor sprinklers at 7.0 psi
  • Recognize applicable types of pipe and fittings used in NPFA 13D systems.
  • Discuss the differences in multipurpose and standalone systems
  • Describe the considerations included and the process involved in performing hydraulic calculations for NFPA 13D systems.
  • Identify when the NFPA 13D “simplified” method cannot be used

It is highly recommended that the student have a copy of NFPA 13D Installation of Sprinkler Systems in One- and two-Family Dwellings and Manufactured Homes, 2007 Edition, readily available for reference during this seminar.
