Chapter 3 – DefinitionsChapter 3 Definitions(Dwelling Unit)

3.3.10 Dwelling Unit (for sprinkler system installations). One or more d f th f i di id l li i t th irooms arranged for the use of one or more individuals living together, as in a

single housekeeping unit normally having cooking, living, sanitary, and sleeping facilities that include, but are not limited to, hotel rooms, dormitory rooms apartments condominiums sleeping rooms in nursing homes androoms, apartments, condominiums, sleeping rooms in nursing homes, and similar living units.

Clarifies where special design criteria for dwelling units may be applied utilizing NFPA 13 for


criteria

Chapter 3 – DefinitionsChapter 3 Definitions(Continuous & Noncontinuous Obstruction)

3.3.18 Obstruction.

3.3.18.1 Continuous Obstruction. An obstruction located at or below the level of sprinkler deflectors that affect the discharge pattern of two or more p g padjacent sprinklers.

3 3 18 2 Noncontinuous Obstruction An obstruction at or below the level of3.3.18.2 Noncontinuous Obstruction. An obstruction at or below the level of the sprinkler deflector that affects the discharge pattern of a single sprinkler.

These terms were used in previous editions but were never specifically defined. These new


definitions were added to clarify obstruction rules and sprinkler positioning.

Chapter 3 – DefinitionsChapter 3 Definitions(Sprinkler System)

3.3.22* Sprinkler System. A system that consists of an integrated network of i i d i d i d ith fi t ti i i t d d th tpiping designed in accordance with fire protection engineering standards that

includes a water supply source, a water control valve, a waterflow alarm, and a drain and is commonly activated by heat from a fire, discharging water over the fire area The portion of the sprinkler system above ground is a network ofthe fire area. The portion of the sprinkler system above ground is a network of specifically sized or hydraulically designed piping installed in a building, structure, or area, generally overhead, and to which sprinklers are attached in a systematic pattern The system is commonly activated by heat from a firea systematic pattern. The system is commonly activated by heat from a fire and discharges water over the fire area.

This revised definition will help clarify the limitations of a system as it applies to NFPA 13 and


25.

Chapter 3 – DefinitionsChapter 3 Definitions(Sprinkler System)

A.3.3.22 Sprinkler System. As applied to the definition of a sprinkler system, each system riser serving a y , y gportion of a single floor of a facility or where individual floor control valves are used in a multistory building should be considered a separate sprinkler system. Multiple sprinkler systems can be supplied by a

l icommon supply main.

Shown here are typical floor control assemblies


which are considered separate systems.

Chapter 3 – DefinitionsChapter 3 Definitions(Premixed Antifreeze Solution)

3.4.1.1 Premixed Antifreeze Solution. A mixture of an antifreeze material ith t th t i d d f t i d b th f t ithwith water that is prepared and factory-mixed by the manufacturer with a

quality control procedure in place that ensures that the antifreeze solution remains homogeneous and that the concentration is as specified.

Sprinkler contractors once mixed their own solutions using pure antifreeze and water. The purity, actual percentage of concentration, and homogeneity of the solution were


questionable at best.

Chapter 3 – DefinitionsChapter 3 Definitions(Clearance to Ceiling)

3.9.1.5 Clearance to Ceiling. Th di t f th t fThe distance from the top of storage to the ceiling above.

This new definition has an impact on the design criteria for storage


occupancies.

Several major changes were made in chapter 6 that affects the installation of new sprinkler


systems, as well as the renovation of existing systems.

CHAPTER 6 – System Components d H dand Hardware

(Removal of Sprinklers)

6.2.1.1 When a i kl h bsprinkler has been

removed for any reason, it shall not be reinstalledreinstalled.

Because even slight damage to a sprinkler during theto a sprinkler during the removal process could cause a premature discharge, the committee decided to

h b ll


prohibit any re‐installation.


(Underground Pipe)

6.3.1.1.1* Underground pipe shall be itt d t t d i t th b ildipermitted to extend into the building

through the slab or wall not more than 24 in. (0.6 m).

This change limits the amount of underground pipe that can project into the building. The 24” allows room for the transition to the above


ground piping system.


(Nonmetallic Pipe)

6.3.7* Nonmetallic Pipe. Nonmetallic pipe in accordance with Table 6.3.1.1 shall be investigated for suitability in automatic sprinkler installations and listed for this service.for this service.

residential system types as used only in NFPA 13D.

Chapter 3 – DefinitionsChapter 3 Definitions(Multipurpose Piping Sprinkler System)

3.3.11.3* Multipurpose Piping Sprinkler System. A piping system p y p p g yintended to serve both domestic needs in excess of a single fixture and fire protection needs from one common piping system throughout the dwelling unit(s).

This new language will clarify that a multipurpose system is one system throughout the


dwelling unit that feeds both fire protection and domestic fixtures.

Chapter 3 – DefinitionsChapter 3 Definitions(Passive Purge Sprinkler System)

3.3.11.5* Passive Purge Sprinkler System. A type of sprinkler system that i l t il t i dditi t th fi i klserves a single toilet in addition to the fire sprinklers.

A.3.3.11.5 Passive Purge Sprinkler System. The domestic plumbing fixture should be on a remote portion of the system or the system should be designed

l th t t th h j it f th t h thas a loop so that water moves through a majority of the system when the fixture is used. This type of system is also called a “flow through system” in much of North America.

3.3.11.9* Stand-Alone Sprinkler System. A sprinkler system where the b d i i l fi i klaboveground piping serves only fire sprinklers.

A.3.3.11.9 Stand-Alone Sprinkler System. Underground piping is permitted to serve domestic use as well as sprinkler system use, but once the split is made between systems, the piping serving fire sprinklers only serves the fire sprinklers.


Standalone is a commonly used term and this new definition will provide a specific meaning.

Chapter 4Chapter 4 –– General RequirementsGeneral RequirementsChapter 4 Chapter 4 General RequirementsGeneral Requirements

Changes include:

Some requirements relocated

Some of the requirements of chapter 4 in the 2010 edition were relocated to some of the new


chapters in the 2013 edition.

Chapter 5Chapter 5 –– System ComponentsSystem ComponentsChapter 5 Chapter 5 System ComponentsSystem Components

Changes include:

Spare sprinklers not required

Lower sprinkler pressure ratingsp p g

Special piping allowances

Pressure reliefPressure relief

Special fitting allowances

Most of the changes are related to lower pressures being allowed for the materials and


components being installed in certain systems.

Chapter 5 – System Components(Sprinkler Pressure Rating)

Chapter 5 System Components

5.2.1 Listed residential sprinklers installed in systems complying with 5.2.2.3, 5.2.2.4, 5.2.5.3, or 5.2.5.4 shall be permitted to have a minimum pressure rating of 130 psi (8.9 bar).rating of 130 psi (8.9 bar).

Sprinklers listed with a lower pressure rating can used in certain types of residential piping


systems.

Chapter 5 – System Components(Residential Sprinkler Piping)


5.2.2.2* Pipe used in sprinkler systems other than those addressed in 5.2.2.3 or 5.2.2.4 shall be designed to withstand a working pressure of not lessdesigned to withstand a working pressure of not less than 175 psi (12.1 bar).5.2.2.3 Nonmetallic pipe used in multipurpose piping systems and passive purge systems not equippedsystems and passive purge systems not equipped with a fire department connection shall be designed to withstand a working pressure of not less than 130 psi (8.9 bar) at 120 F (49 C).( ) ( )

Nonmetallic piping with lower pressure ratings than normally used in NFPA 13 and 13R


systems are allowed in NFPA 13D



5.2.2.4 Nonmetallic pipe used in wet pipe sprinkler systems not equipped with a fire department connection and provided with a pressure-reducing valve set no higher than 80 psi (5.5 bar) shall be designed to withstand a workingno higher than 80 psi (5.5 bar) shall be designed to withstand a working pressure of not less than 130 psi (8.9 bar) at 120 F (49 C) and 100 psi (6.9 bar) at 180 F (82.2 C).

The use of a pressure reducing valve with a setting of 80 psi, provides a level of assurance


that the pressure rating of the pipe and fittings will not be exceeded.



5.2.2.4.1 If the maximum static pressure from the water supply is less than or equal to 80 psi (5.5 bar), pipe designed to withstand a working pressure of not less than 130 psi (8.9 bar) at 120 F (49 C) and 100 psi (6.9 bar) at 180 Fless than 130 psi (8.9 bar) at 120 F (49 C) and 100 psi (6.9 bar) at 180 F (82.2 C) shall be permitted to be used without a pressure-reducing valve.5.2.2.4.2 If a pressure-reducing valve is used to comply with 5.2.2.4, an automatic means of pressure relief shall be installed on the sprinkler systemautomatic means of pressure relief shall be installed on the sprinkler system side of the pressure-reducing valve.

For situations where the water supply is not going to reach 80 psi, such as a water supply off a pump and tank for the sprinkler system where the churn pressure for the pump is less than


80 psi, there is no need for the pressure reducing valve.
