As the design of automatic fire sprinkler systems becomes more complex the responsibility of the system designer and the AHJ reviewing those plans increases as well. This virtual seminar discusses 10 errors - either of omisison or misapplication - frequently found on plans. Included in the discussion are sketches and examples of those scenarios, along with references to the applicable sections of the 2002 edition of NFPA-13, Standard for the Installation of Sprinkler Systems. This seminar will give AHJ's and designers a useful explanation of the issues regarding these mistakes.
Upon completion of this program you will be able to:
- Recognize the effects of sloped ceilings in NFPA 13 for protection
of various occupancies
- Identify the various construction types contained in NFPA 13
- Unobstructed – five examples
- Obstructed – seven examples
- Explain the limitations on sprinkler coverage areas for:
- Light hazard occupancies
- Ordinary hazard occupancies
- Extra hazard occupancies
- Interpret deflector position requirements for various construction
- Identify “boiler plate” notes which are not applicable
to the specific project
- Recognize incompatibility between general notes, plans and
- Calculate the loss for flow through a meter in an NFPA 13D
compliant sprinkler system
- Solve for the loss in pressure through various valves at various
- Explain the loss or gain in pressure due to elevation
- Determine if the hydraulics for a “grid” system
have been “peaked”
- Recognize when “canned” details are not accurate
in their depiction of installation conditions
- Demonstrate how the minimum length of the most remote area
parallel to the branch lines is established
- Describe when branch line restraint is required and when it
