Public Input No. 37-NFPA 13R-2016 [ Section No. 1.1 [Excluding any Sub-Sections] ]

This standard shall cover the design and installation of automatic sprinkler systems for protection againstfire hazards in residential occupancies up to and including four stories in height, that are located inbuildings not exceeding 60 ft (18 m) in height above grade plane.

Statement of Problem and Substantiation for Public Input

At a recent ICC code hearing, there was extensive discussion about whether the 4-story limit in NFPA 13R relates to grade plane, as defined in the building code. It does not.

Although the existing NFPA 13R text was thought to be clear that the 4-story limit is not with respect to grade plane (which is why "in height" was repeated in the existing scope text), it has become apparent that the existing text needs to be slightly adjusted to better convey this point. This is particularly important with respect to application of NFPA 13R to buildings that are constructed in accordance with pedestal building options under model building codes. Proper application of the standard to pedestal construction, consistent with this proposal, is clearly conveyed in the NFPA Residential Sprinkler Systems Handbook, but adjusting the scoping text should help to eliminate any remaining confusion.

Press-Connect Fitting-

A permanent mechanical connection for joining copper tubing, steel and stainless steel pipe utilizingelastomeric seal or an elastomeric seal and corrosion-resistant grip ring or rings. Fitting connections aremade with a pressing tool and jaws or rings approved by the fitting manufacturer for use in accordance withthe product listing.


Currently there is no definition for Press-Connect fittings in NFPA 13R. The term Press-Connect Fitting is used in both the IAPMO and ICC codes. The wide use of Mechanical type fittings has created the need to identify fittings such as Press-Connect and provide definitions to prevent confusion between mechanical fitting types and to help identify the correct standards these fittings are required to be listed to. This definition is proposed to prevent confusion within the industry and aligns definitions for these type fittings. This definition will also help to prevent incorrect terminology in the industry such as referring to Press-Connect fittings as Propress which we have all commonly seen. As the Manufacturer of Propress we do like that our brand name is the name used by those in the industry when referring to Press-Connect fittings, but we do want the industry to have the correct terminology of the fittings to avoid any confusion between manufactured products.

5.1.3 Rated Pressure.

System components shall be rated for the maximum system working pressure to which they are exposedbut shall not be rated at less than 175 psi (12.1 bar) for components installed above ground and 150 psi(10.4 bar) for components installed underground between the water supply and the system riser. When theunderground piping can be supplied or pressurized by a Fire Department Connection (FDC), theunderground piping shall be designed to withstand a working pressure of not less than 200 psi (Class 200),or 50 psi greater than the system design pressure, whichever is greater.


This PI intends to require higher pressure ratings for underground lines that can be fed by Fire Department Connections. Delivery of water at Fire Department Connections can cause pressures that exceed 150 psi. Typically, use of 200 psi rated line can withstand the pressures delivered at the FDC. However, when higher pressures are required at the FDC due to system demands, the underground line is required to be listed for 50 psi above that demand pressure. The 50 psi above design pressure is to allow for pipe to be listed for the pressure used during the hydrostatic test.

The addition of the standard will also be consistent with referenced standards in the ICC Fire Code TABLE AG101.1 and Section AG102 for UL 1821 and will help guide manufacturer's to another widely used Standard for Metallic Sprinkler Pipe for Fire Protection Service and will help to prevent confusion within the industry as to the applicable standards for Fire Protection piping for materials.. This addition will guide manufacturers, designers and installers to the correct standards that comply with NFPA 13, 13R and 13D requirements which these same changes have been proposed. There is no fiscal impact associated with these proposals.

5.2.1.4

Nonmetallic pipe used in isolated portions of wet pipe sprinkler systems where that portion of the system isprovided with a pressure-reducing valve set to no more than 80 psi (5.5 bar) shall be designed to withstanda working pressure not less than 130 psi (9 bar) at 120°F (49°C) and 100 psi (6.9 bar) at 180°F (82°C).


By requiring that system components be rated at 175 psi an assurance is made that there will be no failures due to excessive pressure in the system coming either from a fire pump or from a fire truck when they arrive on scene and hook up to the fire department connection on the outside of the building. The purpose of the fire department connection is both to provide a reliable water supply to supplement the sprinkler system and to provide water pressure and flow in the standpipe for fire department hose connections. There is no reason for the sprinkler system to have excessive pressure applied to the sprinklers themselves, simply providing a sustainable water flow is enough. Therefore, limiting the pressure to 80 psi with the use of pressure reducing valves will not have a negative impact on the performance of the sprinkler system. In fact in many cases there are reduced pressure zone valves coming off standpipes for the sprinkler system on each floor already. If the pressure is limited to 80 psi for each zone/area utilizing a non-metallic type of pipe that doesn’t have the 175 psi pressure rating there should be no issues allowing the use of these types of pipes in 13R applications. Precedence for this has been set in NFPA 13D with the allowance of a wet pipe standalone sprinkler system utilizing non-metallic pipe that has a listed pressure below 175 psi as long as the pressure was limited to no more than 80 psi.

In many residential buildings, there are private garages that exceed 400 square feet. However, many of these garages are protected with residential sprinklers or standard sprinklers with a .05 density. These concealed spaces are generally wood floor trusses with dwelling units above. The concealed space itself is technically light hazard and in most cases it is a rated assembly. In the spirit of providing life safety verses property protection, non metallic piping should be allowed to run in these spaces even when the room is greater than 400 square feet.

5.2.2.2.1

Pipe or tube installed in accordance with 5.2.2.2 shall be permitted to be installed exposed, in accordancewith their listing.

5.2.2.2.2

Pipe or tube installed in accordance with 5.2.2.2 shall be permitted to be installed in ordinary hazard rooms

larger than 400 ft 2 (37 m 2 ) where the pipe is concealed within a 1-hour fire resistance-rated assembly.


New Section 5.2.2.1 is a clarification and makes NFPA 13R consistent with Section 6.3.9.6.1 of NFPA 13.

In residential buildings with ordinary hazard rooms larger than 400 square feet, the installer is required to transition from listed nonmetallic pipe to metallic pipe. New Section 5.2.2.2.2 eliminates that issue. The requirement to install the pipe or tube within a 1-hour fire resistance-rated assembly will insure the integrity of the piping systems until the sprinkler heads activate.

UL 213 is currently not referenced by NFPA 13R. UL 213 is a widely used standard for Rubber Gasketed Fittings for Fire Protection Service for Steel, Stainless Steel and Copper fittings.. Many manufacturers are listed to UL 213 and having a reference in the code will help to identify the correct standard for building officials as well as sprinkler designers. As more manufacturers produce press-connect and similar type fittings, this addition will help to guide them to a standard that meets NFPA 13R requirements.

UL 1821 standard is a widely used standard for Plastic Pipe and Fittings for Fire Protection Service. Currently this standard is not mentioned as a referenced standard in the pipe or fittings table. The addition of the standard will

also be consistent with referenced standards in the ICC Fire Code TABLE AG101.1 and Section AG102 and will help to prevent confusion within the industry. This addition will guide manufacturers, designers and installers to the correct standards that comply with NFPA 13, 13R and 13D requirements which these same changes have been proposed.

There is no fiscal impact for these proposals.

Currently NFPA 13R does not currently reference ASME B16.51 This Standard establishes requirements for cast copper alloy, wrought copper, and wrought copper alloy, press-connect pressure fittings for use with hard drawn seamless copper water tube conforming to ASTM B88 for piping systems conveying water. The press-connect system (tube, fitting, and joint) conforming to this Standard is for use at a maximum pressure of 1 380 kPa (200 psi) over the temperature range from 0°C to 93°C (32°F to 200°F). This Standard provides requirements for fittings suitable for press-connect joining and covers the following:(a) size designations(b) pressure–temperature ratings(c) terminology(d) dimensions and tolerances(e) materials

5.2.9.4

Nonmetallic fittings used in isolated portions of wet pipe sprinkler systems where that portion of the systemis provided with a pressure-reducing valve set to no more than 80 psi (5.5 bar) shall be designed towithstand a working pressure not less than 130 psi (9 bar) at 120°F (49°C) and 100 psi (6.9 bar) at 180°F(82°C).


By requiring that system components be rated at 175 psi an assurance is made that there will be no failures due to excessive pressure in the system coming either from a fire pump or from a fire truck when they arrive on scene and hook up to the fire department connection on the outside of the building. The purpose of the fire department connection is both to provide a reliable water supply to supplement the sprinkler system and to provide water pressure and flow in the standpipe for fire department hose connections. There is no reason for the sprinkler system to have excessive pressure applied to the sprinklers themselves, simply providing a sustainable water flow is enough. Therefore, limiting the pressure to 80 psi with the use of pressure reducing valves will not have a negative impact on the performance of the sprinkler system. In fact in many cases there are reduced pressure zone valves coming off standpipes for the sprinkler system on each floor already. If the pressure is limited to 80 psi for each zone/area utilizing a non-metallic type of pipe that doesn’t have the 175 psi pressure rating there should be no issues allowing the use of these types of pipes in 13R applications. Precedence for this has been set in NFPA 13D with the allowance of a wet pipe standalone sprinkler system utilizing non-metallic pipe that has a listed pressure below 175 psi as long as the pressure was limited to no more than 80 psi. This is the same language submitted for the justification for 5.1.3.1 and 5.2.1.4.

The current language implies that only brazed fittings are to be used in dry pipe and pre-action systems. Copper Press Connect fittings listed to UL 213 Rubber Gasketed Fittings for Fire Protection Service are listed for use in dry and pre-action systems.

Joints for the connection of copper pipe for wet systems shall use solder joints with 95-5 solder metal or ,press-connect, or be brazed.


Currently only soldered or brazed joints are allowed for joining copper per this section.

The addition of press-connect will eliminate the confusion for allowable copper pipe joining as press-connect fittings are the most widely used joints outside of brazed or soldered joints. Section 5.2.9 allows other types of fittings to be used where listed for sprinkler systems but there is a need to identify press-connect fittings within the body of the code as their use is now very familiar with building officials, designers and installers and it will help to clarify terminology when referring to these fittings as Press-Connect and not Propress or Sharkbite names which are commonly used to describe Press-Connect and Push Fit style fittings. By adding this terminology it will eliminate confusion of the name of the fitting type.

Listed quick-response sprinklers shall be permitted to be installed in dwelling units meeting the definition ofa compartment, as defined in Section 3.3, where no more than four sprinklers are located in the dwellingunit .


There is no reason to limit the use of quick response sprinklers to a dwelling unit of 4 sprinklers. The density is double what is required of a residential sprinkler and is adequate for NFPA 13. Also, if there were 6 sprinklers in the dwelling unit, then per 6.2.1.3.1, the design area would be 6 sprinklers.

Sprinklers in closets containing ventless clothes dryers shall be of the intermediate-temperatureclassification or higher.


Ventless clothes dryers placed within closets have the potential to raise ceiling temperatures above 100 F (38 C) for sustained periods of time, potentially weakening the operating mechanisms of ordinary temperature rated fire sprinklers over months or years of use, leading to inadvertent operations. While ventless clothes dryers have been used in Europe for many years, they are fairly new to the North American market, where vented clothes dryers have been the norm. More expensive than vented dryers, they generally incorporate condensers in a “two-loop” system to first heat some incoming air, allowing it to absorb moisture from the damp clothes, then continually condense the heated moist air to release the water before recirculating the resulting dry air within the clothes dryer. Unlike vented dryers, where moist heated air is exhausted to the building exterior, these devices capture the water to a drain or pan, while the heat from the condensing cycle is exhausted into the immediate area.

The condensers in combination machines that both wash and dry the clothes are generally water-cooled, such that quantities of cold water are used to condense the moisture evaporated from the clothes during the drying cycle, and pumped away through the drain line. But the standalone dryer units are air-cooled, using the ambient air as a heat sink. While this heat can be dissipated in a large laundry room, it can be expected to raise the temperatures within a laundry closet to levels unacceptable for ordinary temperature rated sprinklers. All standalone ventless dryers in the market are reportedly of this type.

6.4.6.3.4.3.1

Sprinklers shall be permitted to be installed closer than 3 ft (914 mm) from an obstruction such as a light inhallways where the obstruction is on the width of the hallway.


Many times in hallways there are lights that create obstructions. If the sprinkler is placed adjacent to the light with the light between the sprinkler and the wall, the amount of obstructed space is minimal. The sprinkler is still protecting the length of the hallway in both directions. This should be an acceptable level of protection as the "shadow" created by that light will be considerably less then 15 square feet.

6.5.5 Temporary Protection During Construction, Alteration or Demolition

During construction, alteration or demolition, the use of temporary fire sprinkler protection installed inaccordance with approval of the AHJ shall be permitted as supplemental protection of hazardousconditions.

A.6.5.5 During construction, alternation and demolition, there are many hazardous conditions, such ascutting, welding, grinding and hazardous product storage that can be made safer by installing a temporaryfire sprinkler system. Without this section, there would be no allowance in NFPA 13R to permit suchsystems because they would not fully comply with the provisions of the standard. Given that suchprotection would be supplemental to any other protection that would be required, there is no harm inallowing this additional safety feature on a temporary basis if the design and installation is consideredreasonable by the AHJ.


There is a history of major fires during construction that were associated with hazardous conditions during construction. In some cases, developers will consolidate hazardous operations, such as a welding or grinding area, in a designated area of a building to increase control of the operation. Site managers will sometimes provide temporary sprinkler systems to supplement fire extinguishers and other safety features (not diminishing any other required protection feature) to improve safety, but there have been cases where AHJs have ordered these systems removed because they aren't currently permitted by NFPA 13 or NFPA 13R. Given that it's better to have some protection, as approved by the AHJ, vs.prohibiting an additional measure of safety, this proposal adds an allowance in NFPA 13R to permit temporary installations. A parallel proposal is being submitted to NFPA 13.

6.6.6.1 Where the fuel-fired equipment is above all occupied areas , sprinkler protection shall not berequired in the concealed space.

The change reflects recent revisions made to NFPA 13D, Section 8.3.5.1, recognizing that fuel-fired equipment in attics is not uniquely hazardous to warrant the complexity of having to install a single sprinkler in an attic space that will often be required to be protected from freezing. Given the pending prohibition of anti-freeze systems, having to install a freeze-protected single sprinkler over a fuel-fired appliance will become even more difficult in the future.

6.6.6.1

When

Protection of Fuel-Fired Equipment. Where protection of fuel-fired equipment is

present, at

required by 6.6.4, 6.6.6 and 6.6.7, sprinkler protection shall be provided in accordance with the following:

(1) At least one quick-response

intermediate temperature sprinkler

sprinkler with a minimum k-factor of 5.6 shall be

installed

provided above the fuel-fired equipment. Sprinklers shall be sufficient to cover the fuel-fired equipmentprotection area, which is equal to the entire perimeter of the fuel-fired equipment when viewed on a planview.

(2) Where the sprinkler(s) protecting the fuel-fired equipment is located under a ceiling with slope equal toor greater than a 4:12 pitch, a minimum of one sprinkler shall be located above the edge of the fuel-firedequipment protection area, on the upslope side of the equipment.

(3) Freeze protection shall be provided in accordance with 5.4.2.



The purpose of this PI is to provide minimum design requirements for protection of fuel-fired equipment. Sections 6.6.6 (and proposed 6.6.7) require protection in spaces that contain fuel-fired equipment. However the base code does not provide criteria for protection of these spaces. One interpretation of this code section would indicate that the entire space would need to be provided with fire sprinklers. However, this is not seen as prudent, as it could lead to requiring sprinklers throughout an attic simply due to having a few pieces of fuel-fired equipment in a small portion of the attic. Therefore, this code section is proposed to simply indicate that a minimum of one sprinkler head be located above the fuel-fired equipment. Additional sprinkler heads may be required if there are multiple pieces of equipment, which would together form an area that is called “fuel-fired equipment protection area” and is simply an area with boundaries that contain all fuel-fired equipment within those boundaries. Where there is a slope to the roof, it is felt that the heat from fire will travel up the slope of the roof. Therefore, the proposal requires that in cases where the slope exceeds 4:12, then at least one of the sprinkler heads need to be located at the edge of the protection area on the upslope side, in order to ensure that a head activates.

7.4.1 Occupied Attics and Attics Used for Storage. Attics that are intended for occupancy or storageshall comply with Section 7.1, where the attic is part of the dwelling unit, or Section 7.2, where the attic isoutside of the dwelling unit. Sprinkler temperature ratings shall comply with Section 6.2.3.

7.4.2 Fuel Fired Equipment. Where fuel-fired equipment is installed in an attic that is not otherwiserequired to have sprinklers, at least one quick-response intermediate temperature sprinkler shall beinstalled above the equipment.

7.4.3* Other Attics. Attics that are not required by Section 7.4.1 to have sprinklers shall bepermitted to have protection in accordance with one of the following. Sprinkler temperature ratingsshall comply with Section 6.2.3.

1. Protection complying with NFPA 13.

2. Protection using sprinklers that are specifically listed to provide attic protection inresidential occupancies using a discharge density of not less than 0.05 gpm/ft2 (2.04mm/min) and a design area of not less than 4 sprinklers.

A.7.4.2 NFPA 13R does not require installation of sprinklers in attics that are not intended for occupancyor storage. However, model building codes sometimes require protection of attics in tall, combustible-framed residential occupancies that are otherwise allowed to follow NFPA 13R. Such protection ispermitted to be provided by sprinklers or other means allowed by the model building code or NFPA 13, asspecified for protection of combustible concealed spaces. Common methods of protection in lieu ofsprinklers include filling the space with non-combustible insulation, using fire-retardant treated wood, orusing non-combustible materials. Even though sprinklers are not mandatory for attic protection underNFPA 13R, NFPA 13R offers appropriate design requirements for cases where sprinklers are provided andsets design benchmarks that parallel what is permitted for garages.

Renumber existing 7.4 as 7.5


Section 6.6.6 and 6.6.6.1 require sprinklers in attics that are intended for living or storage purposes and for attics that contain fuel-fired equipment, and it is helpful to provide guidance on attic protection in Chapter 7 to correlate. In addition, model building codes are adding requirements for some other attics to be protected with sprinklers or other acceptable means for protection of concealed spaces. It is important for NFPA 13R to provide guidance on protection of attics for these situations as well. The proposal parallels the design guidance for garages by offering an option to use not less than a 0.05 gpm/sqft density and not less than a 4 sprinkler design basis. However, the minimum density and minimum number of sprinklers would have to be determined based on testing and a listing for this specific hazard, as validated by a listing agency. The second design option is necessary to state in NFPA 13R to provide an alternative to the general provisions in Section 6.6.8, which would otherwise require compliance with NFPA 13 as the only basis for attic sprinkler protection.

A single automatically controlled fire pump in accordance with NFPA 20 shall be an acceptable water supply source. Where a fire pump is installed, the fire pump shall be installed in accordance with NFPA 20. 9.5 Water Tanks. Where a water tank is installed, the water tank shall be installed in accordance with NFPA 22. 9.6* Domestic Demand. Domestic demand for the building being calculated shall be included as part of the overall system demand for systems with common domestic/fire mains where no provisions are made to prevent the domestic waterflow upon sprinkler system activation. 9.8 Penstocks, flumes, Rivers, or Lakes. Water supply connections from penstocks, flumes, rivers, lakes or reservoirs shall be arranged to avoid mud and sediment and shall be provided with approved double removable screens or approved strainers installed in an approved manner. 9.97 Non–Fire Protection Connections. Sprinkler systems with non–fire protection connections shall not be permitted.

A.9.4.23 The connection to city mains for fire protection is often subject to local regulation of metering and backflow prevention requirements. Where connections are made from public waterworks systems, such systems should be guarded against possible contamination as follows (see AWWA M14, Recommended Practice for Backflow Prevention and Cross Connection Control). A.9.5.1 Preferred and acceptable water supply arrangements are shown in Figure A.9.5.13(a), Figure A.9.9.13(b), and Figure A.9.5.13(c). Where it is necessary to use a meter between the city water main and the sprinkler system supply, an acceptable arrangement as shown in Figure A.9.5.13(c) can be used. Under these circumstances, the flow characteristics of the meter are to be included in the hydraulic calculation of the system. Where a tank is used for both domestic and fire protection purposes, a low water alarm that actuates when the water level falls below 110 percent of the minimum quantity specified in Section 9.2 should be provided. A.9.3(1) Pumps that are owned and operated by thea public or private waterworks utility are not required to meet NFPA 20 because the waterworks industry standards for reliability and redundancy take care of concerns regarding reliability for fire‐fighting operations. If there is any concern over the

use of these non NFPA 20 pump installations, then the waterworks would not be considered reliable and would not be permitted as a water supply. An authority having jurisdiction has the authority to review a combined domestic/fire protection pump arrangement and determine whether or not the reliability and redundancy meets the intent of NFPA 20, even if the exact arrangement of equipment does not meet the rules of NFPA 20. INSERT FIGURES A.9.3(a), A.9.3(b), and A.9.3(c) and rename as A.9.5.1(a), A.9.5.1(b), and A.9.5.1(c) Private pumps taking suction from the waterworks system need to comply with NFPA20, even if they supply both fire protection and domestic water uses, unless they comply with the same waterworks industry standards for reliability and redundancy as the pumps owned by a waterworks utility. A.9.3(4) Pumps taking water from a stored source need to meet NFPA 20 requirements, even when they supply both fire protection and domestic water uses, unless they comply with waterworks industry standards for reliability and redundancy. An authority having jurisdiction has the authority to review a combined domestic/fire protection pump arrangement and determine whether or not the reliability and redundancy meets the intent of NFPA 20, even if the exact arrangement of equipment does not meet the rules of NFPA 20. A.9.6 Table A.9.6(a) and Table A.9.6(b) can be used to determine a domestic design demand. Using Table A.9.6(a), the total number of water supply fixture units downstream of any point in the piping serving both sprinkler and domestic needs is determined. Using Table A.9.6(b), the appropriate total flow allowance is determined and added to the sprinkler demand at the total pressure required for the sprinkler system at that point.


9.3.1

The flow and pressure of a public water supply shall be determined from waterflow test data or otherapproved method.

9.3.1.1 Water supply fluctuations must be addressed in the design of sprinkler systems, as required by theAuthority Having Jurisdiction.

9.3.1.2 Safety factors must be addressed in the design of sprinkler systems, as required by the AuthorityHaving Jurisdiction.


The intent of this proposal is to recognize the need for evaluation of water supply fluctuations and safety factors in system design.

The International Codes now specifically require that water supply fluctuations be addressed in sprinkler system design as follows (from 2015 IFC, Section 903.3.5):"For connections to public waterworks systems, the water supply test used for design of fire protection systems shall be adjusted to account for seasonal and daily pressure fluctuations based on information from the water supply authority and as approved by the firecode official."

Additionally, NFPA 14 (2016 edition) now states: "10.1.1 Daily and seasonal flow and pressure fluctuation data shall be provided by the water purveyor, and the fire protection design must account for both high and low variations.10.1.1.1 Where these data are not available, design shall be based on the available water flow data."

This proposal is simply an intent to recognize the need for and importance of water supply fluctuation to be evaluated, as well as to recognize that many jurisdictions require safety factors in the design of sprinkler systems. There is an additional similar proposal to NFPA 13 in this regard to move the requirement to address pressure fluctuations back into the body of that standard, rather than just in the Appendix.

9.4.1* Knowledge of the water supply and engineering judgment taking into account reasonabledaily and seasonal fluctuations not extreme conditions.

9.4.2* Use of the following formula:

P = The pressure available from the water supply to use for a fire protection system that willbe calculated for a given flow (Q)

Q = The flow that will be used to calculate the available pressure from the water supply.

P R = The residual pressure measured during the waterflow test while the flow Q R was

discharging from the water supply.

P S = The static pressure measured during the waterflow test.

Q R = The flow discharging from the water supply when P R was measured.

P L = The expected low static pressure at the location of the test results accounting for

daily and seasonal fluctuations (not extreme conditions) obtained from the water utility. Where the water authority does not provide P L , see 9.4.3.

9.4.3 Where the water authority does not provide a value for P L , the value of P L shall be

calculated from the following formula:

P L = P S – 10 psi



Safety_Margin_Proposal-NFPA_13R.docx

This provides the formula that I can't get into Terra View and shows the effect of the annex text as well.


There needs to be a reasonable adjustment to water supply data in order to accommodate changes due to daily and seasonal fluctuations. The fact that this is currently not a requirement allows the design of fire protection systems that are known by the designer to have an ineffective water supply almost immediately after installation.

This proposal takes care of the traditional arguments against a mandated safety margin by creating a standardized method of calculating that safety margin; however, this standardized method is only used if there is no information regarding the water utility. So, those situations where the fluctuations in the water delivery are known at a particular location, then these take priority.

Spelling out the fact that NFPA 13R is not expecting unusual circumstances like water main breaks and 100 year droughts should help alleviate liability concerns on the part of the water utility, which should lead to a more open dialog between the fire protection professional and the water utility representative. The reality is that extreme conditions like 100 year droughts and water main breaks are better handled by the Impairment Procedures of NFPA 25.

One of the concerns about this proposal last cycle was that there was no way to account for the situation where the water utility brings more pumps on line as the flow demand increases. These situations produce a water

P = The pressure available from the water supply to use for a fire protection system that will be calculated for a given flow (Q) Q = The flow that will be used to calculate the available pressure from the water supply. PR = The residual pressure measured during the waterflow test while the flow QR was discharging from the water supply. PS = The static pressure measured during the waterflow test. QR = The flow discharging from the water supply when PR was measured. PL = The expected low static pressure at the location of the test results accounting for daily and seasonal fluctuations (not extreme conditions) obtained from the water utility. Where the water authority does not provide PL, see 9.4.3.

9.4.3 Where the water authority does not provide a value for PL, the value of PL shall be calculated from the following formula:

PL = PS – 10 psi A.5.1.2 An adjustment to the waterflow test data to account for the following should be made, as appropriate: (1) Daily and seasonal fluctuations (2) Possible interruption by flood or ice conditions (3) Large simultaneous industrial use (4) Future demand on the water supply system (5) Other conditions that could affect the water supply

A.9.4.1 The purpose of the adjustment is to take into account reasonable daily and seasonal variations in the water supply, which are easily predicted and tracked by a water utility. It is not the intent to use this section to account for unusual conditions such as 100 year droughts or water main breaks. These unusual conditions are handled through the Impairment Procedures of NFPA 25 and should not be considered when determining the ability of a water supply to meet the demand of a fire protection system under more normal circumstances. A.9.4.2 Consider the following example. A waterflow test is conducted at a location where a city water main is going to be tapped for a new sprinkler system. During the test, the static pressure is measured at 70 psi, the residual pressure is measured at 50 psi while 1300 gpm was discharging from a nearby hydrant. The water utility is contacted and they indicate that a reasonable low static pressure accounting for typical daily and seasonal fluctuations in this area is 55 psi. The equation that describes the water supply available for a fire sprinkler system would be:

551300

705085.1

QP

There are two ways to use this formula. One would be to assume two different values for Q, calculate P and then draw a graph on log 1.85 paper. Any fire sprinkler system demand falling on or below the line on this graph would be acceptable in accordance with NFPA 13 to work with this water supply. In this case, the two easiest flows to pick for Q would be 0 and 1300 gpm. When Q = 0, P is simply 55 psi. When Q = 1300 gpm, P = 35 psi. These two points can be plotted on log 1.85 paper as shown in Figure A.9.4.2. The second way to use this formula would be to calculate the fire protection system and determine the flow necessary to make the system work. Plug this flow into the formula above and see what the available pressure from the water supply will be at that flow. For example, if a sprinkler system connected to this water supply had a demand of 580 gpm, the available pressure from the water supply would be:

551300

5807050

85.1

P

P = (-20)(0.225) + 55

P = 50.5 psi

So, as long as the sprinkler system has a pressure demand less than or equal to 50.5 psi, it will work with this water supply.

Sprinkler system demand can be anywhere in shaded region



9.6

Water storage tanks outside the scope of NFPA 22 shall be permitted when approved by the authorityhaving jurisdiction.


NFPA 22 does not address storage tanks for smaller amounts of water required for an NFPA 13R system. NFPA 22 does not permit plastic tanks such as those often used in 13D applications. Due to the increase in retrofitted systems in adult care "houses", we have found section 9.5 creates an unreasonable cost increase on small businesses by not allowing plastic tanks to be installed. The AHJ should be afforded the opportunity to approve plastic tanks in lieu of larger, more expensive tanks with unnecessarily higher capacities.

Public Input No. 42-NFPA 13R-2016 [ Section No. 9.6 ]

9.6* Domestic Demand.

Domestic For systems with common domestic/fire mains serving more than one dwelling unit, domesticdemand for the building being calculated shall be included as part of the overall system demand forsystems with common domestic/fire mains where no unless provisions are made to prevent the domesticwaterflow upon sprinkler system activation.


Four story townhouses have become a popular type of dwelling unit being constructed in many areas, and the International Building Code requires such structures to have a sprinkler system installed in accordance with NFPA 13R in order to have the fourth story. For the most part, these sprinkler systems are not that different from NFPA 13D systems, other than the number of sprinklers calculated. The issue that arises is that the sprinkler supply is usually from a common supply line feeding the domestic water, and most public water authorities require the sprinkler connection to be on the 'downstream' side of the water meter. Even with a 1-inch water meter (which is the largest size that most water authorities will allow on a single-family dwelling), the domestic demand added to the four-sprinkler flow usually results in a total volume beyond the listed rating of the water meter. Historically, NFPA 13D has not required domestic water demand to be included in the sprinkler demand when the common domestic/fire main serves a single dwelling unit. The same philosophy should apply in the scenario of a four-story single-family dwelling.

NFPA 13R systems need identification signs that spell out the assumptions in the design just like NFPA 13 systems. The signs are required by NFPA 25, so as soon as an NFPA 13R system starts being inspected, it is out of compliance without the signs, so NFPA 13R should be requiring the signs.

The material is proposed to be extracted from NFPA 13 so that it will be automatically identical. This way, if the NFPA 13 committee makes any changes, the NFPA 13R committee will not need to handle the situation. The extract can be updated automatically.

It has become quite common to have four-story single-family dwellings and four-story townhomes, which the International Building Code requires sprinkler design in accordance with NFPA 13R in order to have the fourth story. It becomes extremely expensive and over-burdensome for each dwelling unit to have six spare sprinklers. From almost all aspects other than sprinkler hydraulic design, these dwellings are practically identical to homes protected by sprinkler systems designed by NFPA 13D, which requires no spare sprinklers. By minimizing the required number of spare sprinklers required for four-story single-family dwellings, the cost to the home buyers is thereby reduced.

115 of 143 11/3/2016 2:29 PM

NFPA 13R is appropriate for use as an alternative to NFPA 13 only in those residential occupancies, asdefined in this standard, up to and including four aboveground stories in height. It should be noted thatmodel building codes contain special allowances for "pedestal" or "podium" style buildings , which permitthe story height for structures above the pedestal to be measured from the top surface of the pedestal,rather than from grade plane, and it is the intent of NFPA 13R to follow this model building code method fordetermining the number of stories. Accordingly, it is possible for a 4-story residential structure to be withinthe scope of NFPA 13R even when that structure is constructed on top of a 1-story pedestal. However,where this is allowed, model building codes will require the pedestal portion to be constructed using Type Iconstruction, and limited to buildings that are the pedestal portion will be required to be protected by anNFPA 13 compliant sprinkler system.

Regardless of whether a building does or does not involve a pedestal, NFPA 13R systems are alwayslimited to structures that do not exceed 60 ft (18 m) or less in height above grade plane, which is . Notethat model building codes do not allow building height to be measured from the top of a pedestal. That allowance only applies to determiming the number of stories. The 60-foot overall height limit isconsistent with limits established by model building codes for buildings of Type V construction. The heightof a building structure above grade plane is determined by model building codes, which base the height onthe average height of the highest roof surface above grade plane. For further information on the buildingheight story limits, see model building codes.

Buildings that contain multiple occupancies (either separated or non-separated), accessory occupancies orincidental uses are often subject to special rules that may restrict the use of NFPA 13R. Refer to theadopted building code to determine whether such restrictions are applicable.

The criteria in this standard are based on full-scale fire tests of rooms containing typical furnishings found inresidential living rooms, kitchens, and bedrooms. The furnishings were arranged as typically found indwelling units in a manner similar to that shown in Figure A.1.1(a) , Figure A.1.1(b) , and Figure A.1.1(c).Sixty full-scale fire tests were conducted in a two-story dwelling in Los Angeles, California, and 16 testswere conducted in a 14 ft (4.3 m) wide mobile home in Charlotte, North Carolina. Sprinkler systemsdesigned and installed according to this standard are expected to prevent flashover within the compartmentof origin where sprinklers are installed in the compartment. A sprinkler system designed and installedaccording to this standard cannot, however, be expected to completely control a fire involving fuel loads

that are significantly higher than average for dwelling units [10 lb/ft2 (49 kg/m2)], configurations of fuelsother than those with typical residential occupancies, or conditions where the interior finish has anunusually high flame spread index (greater than 225).

To be effective, sprinkler systems installed in accordance with this standard need to open the sprinklersclosest to the fire before the fire exceeds the ability of the sprinkler discharge to extinguish or control thefire. Conditions that allow the fire to grow beyond that point before sprinkler activation or that interfere withthe quality of water distribution can produce conditions beyond the capabilities of the sprinkler systemdescribed in this standard. Unusually high ceilings or ceiling configurations that tend to divert the rising hotgases from sprinkler locations or change the sprinkler discharge pattern from its standard pattern canproduce fire conditions that cannot be extinguished or controlled by the systems described in this standard.

NFPA 13R references NFPA 13 in many aspects (hanging and bracing, design densities and spacingoutside of dwelling unit, painting and finish of sprinklers, welding, etc.). If this standard does not specificallyaddress a situation, NFPA 13 is a good resource that can be utilized by the installer and the authorityhaving jurisdiction for a solution. It is not the intent of this standard to require compliance with NFPA 13when NFPA 13R is silent on a subject. Only AHJ approval should be required.

Various levels of sprinkler protection are available to provide life safety and property protection. Thisstandard is designed to provide a high, but not absolute, level of both life safety and a lesser level ofproperty protection . Greater protection to both life and property could , but to a lesser degree than wouldbe achieved by sprinklering all areas in accordance with using NFPA 13 , which permits the use ofresidential sprinklers in residential areas .

This standard recommends, but does not require, sprinklering of all areas in the building; it permitssprinklers to be omitted in certain areas. These areas have been proved by NFPA statistics to be thosewhere the incidence of life loss from fires in residential occupancies is low. Such an approach provides areasonable degree of fire safety. (See Table A.1.2 for deaths and injuries in multifamily residentialbuildings.)

It should be recognized that the omission of sprinklers from certain areas could result in the development ofuntenable conditions in adjacent spaces. Where evacuation times could be delayed, additional sprinklerprotection and other fire protection features, such as detection and compartmentation, could be necessary.

Clarification of intent. NFPA 13R is both a life-safety and property-protection standard. It is recognized for property protection by model building codes, which grant construction incentives to buildings protected by NFPA 13R systems, and sprinklers required for protection of balconies and garages are primarily provided for property protection. Certainly, NFPA 13 provides an increased level of protection for both life-safety and property protection, and the proposed revision makes this clear.

A room is still considered a bathroom if it contains just a toilet. Additionally, two bathrooms can be adjacentto each other and are considered separate rooms, provided they are enclosed with the required level ofconstruction .


The requirement that the bathrooms "are enclosed with the required level of construction" should be removed as the 20 minute thermal barrier behind fixtures was no longer required beginning in the 2007 NFPA 13R. As long as each adjacent bathroom meets the definition of a bathroom, they should be considered separate rooms.

Delete this section. The 2015 IBC has added section 903.3.1.2.2 which requires sprinklers in open ended corridors and associated stairways that are not separated. This requirement has been included in 1027.6 but the ICC felt it needed to flag the requirement in the NFPA 13R section. As this committee did with the sprinklers on porches in buildings of Type 5 construction, it should align with what is found in the IBC.

These connections should be installed so that the valve can be opened fully and for a sufficient time periodto ensure a proper test without causing water damage. The drain should be designed and sized to verifythe sufficiency of the water supply.


The purpose of the test connection is to verify that the water flow device is in proper working order. The way to verify the sufficiency of the water supply is to conduct a water flow test, not running water through the test connection.

A.7.1.1.3

All residential sprinklers have been investigated under a flat, smooth, 8 ft (2.44 m) high horizontal ceiling.Some residential sprinklers have been investigated and listed for use under specific ceiling configurationssuch as a horizontal beamed ceiling. The performance of residential sprinklers under flat, smooth,horizontal ceilings has been well documented throughout the life of NFPA 13R. Prior to 2010, severalmanufacturers of residential sprinklers had performed testing and received listings for residential sprinklersunder certain slopes and in certain beam conditions. In 2010, the Fire Protection Research Foundation(FPRF) conducted a research project consisting of 76 FDS simulations and 12 full-scale fire tests. Theresults have been used to develop system design criteria in a generic manner in order to simplify the useof residential sprinklers. Some residential sprinkler listings still exist for situations beyond the scope of thegeneric design. See the FPRF report, “Analysis of the Performance of Residential Sprinkler Systems withSloped or Sloped and Beamed Ceilings,” dated July 2010 for more information.

For examples of selecting a compartment for consideration, see Figure A.7.1.1.3(a) and FigureA.7.1.1.3(b), which show examples of design configurations for compartments based on the presence oflintels to stop the flow of heat.

If a corridor separates the units and garages and garages are separated from each other and each garageis individually accessible by locked door, the individual garage is still accessed by the single dwelling

unit. Residential sprinklers and quick-response sprinklers at 0.05 gpm/ft2 (2.04 L/min/m2) densities havenot been tested for use in garages. However, field experience has shown that they will activate, sound analarm, and provide water distribution that will assist in controlling a fire.


The fuel load/fire threat is effectively the same as that of an attached garage.

A.9.4.1 The purpose of the adjustment is to take into account reasonable daily and seasonalvariations in the water supply, which are easily predicted and tracked by a water utility. It is not theintent to use this section to account for unusual conditions such as 100 year droughts or watermain breaks. These unusual conditions are handled through the Impairment Procedures of NFPA25 and should not be considered when determining the ability of a water supply to meet thedemand of a fire protection system under more normal circumstances.

A.9.4.2 Consider the following example. A waterflow test is conducted at a location where a citywater main is going to be tapped for a new sprinkler system. During the test, the static pressure ismeasured at 70 psi, the residual pressure is measured at 50 psi while 1300 gpm was dischargingfrom a nearby hydrant. The water utility is contacted and they indicate that a reasonable low staticpressure accounting for typical daily and seasonal fluctuations in this area is 55 psi. The equationthat describes the water supply available for a fire sprinkler system would be:

There are two ways to use this formula. One would be to assume two different values for Q,calculate P and then draw a graph on log 1.85 paper. Any fire sprinkler system demand falling onor below the line on this graph would be acceptable in accordance with NFPA 13 to work with thiswater supply. In this case, the two easiest flows to pick for Q would be 0 and 1300 gpm. When Q =0, P is simply 55 psi. When Q = 1300 gpm, P = 35 psi. These two points can be plotted on log 1.85paper as shown in Figure A.9.4.2.

The second way to use this formula would be to calculate the fire protection system and determinethe flow necessary to make the system work. Plug this flow into the formula above and see whatthe available pressure from the water supply will be at that flow. For example, if a sprinkler systemconnected to this water supply had a demand of 580 gpm, the available pressure from the watersupply would be:

P = (-20)(0.225) 55

P = 50.5 psi

So, as long as the sprinkler system has a pressure demand less than or equal to 50.5 psi, it willwork with this water supply.

Sprinkler system demand can be anywhere in shadedregion

Water Supply Adjustment Proposals Put Together Insert new sections as follows: 9.4 Where a waterflow test was conducted to determine the strength of a water supply, the volume and pressure available for use for a fire protection system shall be determined from either 9.4.1 or 9.4.2. 9.4.1* Knowledge of the water supply and engineering judgment taking into account reasonable daily and seasonal fluctuations not extreme conditions. 9.4.2* Use of the following formula:

LR

SR PQ

QPPP

85.1

P = The pressure available from the water supply to use for a fire protection system that will be calculated for a given flow (Q) Q = The flow that will be used to calculate the available pressure from the water supply. PR = The residual pressure measured during the waterflow test while the flow QR was discharging from the water supply. PS = The static pressure measured during the waterflow test. QR = The flow discharging from the water supply when PR was measured. PL = The expected low static pressure at the location of the test results accounting for daily and seasonal fluctuations (not extreme conditions) obtained from the water utility. Where the water authority does not provide PL, see 9.4.3.

9.4.3 Where the water authority does not provide a value for PL, the value of PL shall be calculated from the following formula:

PL = PS – 10 psi A.9.4.1 The purpose of the adjustment is to take into account reasonable daily and seasonal variations in the water supply, which are easily predicted and tracked by a water utility. It is not the intent to use this section to account for unusual conditions such as 100 year droughts or water main breaks. These unusual conditions are handled through the Impairment Procedures of NFPA 25 and should not be considered when determining the ability of a water supply to meet the demand of a fire protection system under more normal circumstances.

A.9.4.2 Consider the following example. A waterflow test is conducted at a location where a city water main is going to be tapped for a new sprinkler system. During the test, the static pressure is measured at 70 psi, the residual pressure is measured at 50 psi while 1300 gpm was discharging from a nearby hydrant.

QP

There are two ways to use this formula. One would be to assume two different values for Q, calculate P and then draw a graph on log 1.85 paper. Any fire sprinkler system demand falling on or below the line on this graph would be acceptable in accordance with NFPA 13 to work with this water supply.

These two points can be plotted on log 1.85 paper as shown in Figure A.9.4.2. The second way to use this formula would be to calculate the fire protection system and determine the flow necessary to make the system work. Plug this flow into the formula above and see what the available pressure from the water supply will be at that flow. For example, if a sprinkler system connected to this water supply had a demand of 580 gpm, the available pressure from the water supply would be:

551300

P

P = (-20)(0.225) + 55

P = 50.5 psi

So, as long as the sprinkler system has a pressure demand less than or equal to 50.5 psi, it will work with this water supply.
