Public Comment No. 5-NFPA 13D-2014 [ Section No. 3.3.11.8 ]

3.3.11.8 Sprinkler System.

For fire protection purposes,A system that consists of an integrated

systemnetwork of

underground and overheadpiping designed in accordance with fire protection engineering standards

. The installation includes one or more automatic water suppliesthat includes a water supply source, a water control valve, a waterflow alarm, and a drain and is commonlyactivated by heat from a fire, discharging water over the fire area . The portion of the sprinkler system

abovegroundabove ground is a network of

speciallyspecifically sized or hydraulically designed piping installed in a building, structure, or area, generallyoverhead, and to which sprinklers are attached in a systematic pattern. The system is

usuallycommonly activated by heat from a fire and discharges water over the fire area. [ 13 3.3.22]

New A.3.3.11.8 A waterflow alarm, although included in this definition, is not a required system componentwithin this standard.


This change would permit consistancy with NFPA13. The additional anex material serves to clarify that the waterflow switch is not a required system component.

The TC states that the material in A.4.5 adequately covers the materials “necessary” for documentation. We agree with the TC that the information in A.4.5 is truly “necessary” documentation for a review of a 13D submittal. Being “necessary” information, it should not be contained in the annex but should be contained in the core text. This requirement is specifically stated in the Manual of Style section 2.3.4.1 “The annexes of codes and standards shall be used for advisory text, explanatory material, and supplementary information and shall not be used for mandatory requirements.” If the requirements of A.4.5 are truly “necessary”, and we agree with the TC that they are, then the text clearly has to be mandatory in order for a “necessary” requirement to be provided by the designer and reviewed by the AHJ.

In addition, if “necessary” information is not provided as part of an initial permit submittal for an AHJ to review the sprinkler design for compliance with NFPA 13D, the TC is basically mandating that the AHJ is going to reject the first submittal of each 13D system because the “necessary” information for a review has not been submitted. This creates additional time delays and additional costs which is directly counter to the TC’s concern that of avoiding “unnecessary” costs.

5.3.1 Type. Any type of pipe or tube acceptable under the applicable plumbing code forunderground supply pipe shall be acceptable as an underground supply for a fire sprinkler systemwhen installed between the point of connection and the system riser.

5.3.2 Depth of Cover.

5.3.2.1 Except where specified otherwise by the applicable plumbing code, the top of the pipe shallbe buried not less than 1 ft (0.3 m) below the frost line for the locality. In those locations wherefrost is not a factor, the depth of cover shall be not less than 2½ ft (0.8 m) to prevent mechanicaldamage.

5.3.2 .2 The depth of cover over water pipes shall be determined by the maximum depth of frostpenetration in the locality where the pipe is laid. The depth of cover shall be measured from the topof the pipe to finished grade, and due consideration shall always be given to future or final gradeand nature of soil.

5.3.3 Protection Against Damage. Unless specified otherwise by the applicable plumbing code, thepipe shall be protected from mechanical and physical damage.


The text comes from NFPA 24. There are many areas in the country that do not have a plumbing code and the text would provide guidance to them. Alos do to the recent harsh winters additional quidance needs to be provided to them. Not all jurisdictions employ a plumbing code. Some adopted plumbing codes don’t address these concerns or does not address fire service mains. The proposal addresses the minimum guidelines when not otherwise addressed by the local plumbing code and recognizes a hierarchy that establishes that the local plumbing code takes precedence.

Public Comment No. 32-NFPA 13D-2014 [ New Section after 8.2.5.6 ]

8.2.5.7

Small areas created by architectural features such as planter box windows, bay windows, and similarfeatures shall be evaluated as follows:

(1) Where no additional floor area is created by the architectural feature, no additional sprinkler protectionis required.

(2) Where additional floor area is created by an architectural feature, no additional sprinkler protection isrequired, provided all of the following conditions are met:

(a) The floor area shall not exceed 18 ft2 (1.7 m2).

(b) The floor area shall not be greater than 2 ft (0.61 m) in depth at the deepest point of thearchitectural feature to the plane of the primary wall where measured along the finished floor.

(c) The floor shall not be greater than 9 ft (2.7 m) in length where measured along the plane of theprimary wall.

(d) Measurement from the deepest point of the architectural feature to the sprinkler shall not exceedthe maximum listed spacing of the sprinkler.

(3) The hydraulic design is not required to consider the area created by the architectural feature.


This language has long been in the annex of NFPA 13D and it is clear that it is the committee's belief that additional floor area created by certain architectural features are not required to have additional sprinkler coverage. As this language is in the annex and not in the enforceable body of the standard, this intent is not consistently applied to such architectural features. Moving this language to the body of the standard would make this longstanding intent of the committee enforceable and clear that additional sprinkler protection is not required in these small areas. As these areas are not required to be included in the hydraulic design area of the systems, these areas are distinct from shadow areas. This language has been included in the body of NFPA 13R and it is not the intent that the requirements of NFPA 13D be more stringent in regards to this issue.

8.2.7.1

In closets and compartments enclosed by walls and a door, including those housing mechanicalequipment, that are smaller than 400 ft3 (11.3 m3), pendent, upright and sidewall residential sprinklersshall be permitted to be installed within 18 inches of the ceiling to avoid obstructions near the ceiling.

Additional Proposed Changes

File Name Description Approved

Computer_Modeling_of_Closet.pdf Computer modeling of closet with residential sprinklers


Small closets, especially those housing mechanical equipment, frequently contain obstructions that make it difficult to place sprinklers within 12 inches of the ceiling. Allowing residential sprinklers to be located further down would allow adequate sprinkler protection of these small closets while avoiding ceiling level obstructions such as ducts and pipes. Based upon CFAST Computer Fire Model, an analysis was performed comparing the performance of sprinklers located 6 inches down from a ceiling in a small room to the performance of sprinklers 18 inches down from the ceiling in an even smaller closet. Based upon this analysis it appears that residential sprinklers 18 inches down from the ceiling in a closet up to 400 ft3 react to a fire at least as quickly as residential sprinklers 6 inches down from a ceiling in a small room. Using equivalency concepts, residential sprinklers could be allowed to be installed within 18 inches of the ceiling in small closets. This analysis is included in this public comment.

Computer Modeling of Closet with Residential Sprinkler 18 Inches from Ceiling

This analysis uses the CFAST Computer Fire Model to compare the performance of sprinklers 6

inches down from the ceiling in a small room to the performance of sprinklers 18 inches down

from the ceiling in an even smaller closet.

Baseline Room: 15 ft x 15 ft x 8 ft

3 sprinkler locations (see Figure 1)

o Sprinkler 1 – 4 ft from south and west walls

o Sprinkler 2 – Centered between east and west walls, 4 ft from south wall

o Sprinkler 3 – 4 inches from south and east walls

All sprinklers 6 inches from ceiling

All sprinklers RTI = 50 (metric units)

Closet: 7 ft x 7 ft x 8 ft (392 ft

Results

The following table compares the activation time of the sprinklers in the small room to that of

the sprinklers in the even smaller closet:

Sprinkler Activation Time in

Small Room (Figure 1)

Activation Time in Closet (Figure 2)

Conclusions

Given this fire location and these three sprinkler locations, it would appear that residential

sprinklers 18 inches down from the ceiling in a closet up to 400 ft3 react to a fire at least as

quickly as residential sprinklers 6 inches down from a ceiling in a small room. Using

equivalency concepts, residential sprinklers could be allowed to be installed within 18 inches of

the ceiling in small closets.

Prior to making any final determination, other combinations of fire size, fire location, and

sprinkler location should be analyzed in the same manner.


8.2.7 Closets.

In all closets and compartments, including those housing mechanical equipment, that are smaller than 400

ft3 (11.3 m3), a single sprinkler at the highest ceiling space ceiling level shall be sufficient without regard toobstructions or minimum distances to wall.

Unless the pipe size is in accordance with the prescriptive pipe sizing method of 10.4.9 , pipe shall besized by hydraulic calculations in accordance with the methods described in NFPA 13, with themanufacturer's listed installation instructions, with 10.4.4 , or with the following general method forstraight-run systems connected to a city water main of at least 4 in. (102 mm) in diameter:

The system flow rate shall be established in accordance with Sections 10.1 and 10.2 , and it shall bedetermined that the flow allowed by the water meter meets or exceeds the system demand and that thetotal demand flow does not exceed the maximum flow allowed by the piping system components.

The water pressure in the street shall be determined.

Pipe sizes shall be selected.

Pressure loss for a water meter, if any, shall be determined and deducted The pipes shall be sizedusing one of the following techniques :

Table 10.4.3(a) shall be permitted to be used, even where the sprinkler demand flow exceeds the meter'srated continuous flow.

Higher pressure losses specified by the manufacturer shall be used in place of those specified in Table10.4.3(a) .

Lower pressure losses shall be permitted to be used where supporting data are provided by the metermanufacturer.

Pressure loss for elevation shall be deducted as follows:

(1) Building height above street (ft) × 0.433 = pressure loss (psi)

(2) Building height above street (m) × 0.098 = pressure loss (bar)

Pressure loss for piping within the building shall be deducted by multiplying the pressure loss associatedwith the pipe material by the total length(s) of pipe in feet (meters).

Pressure loss for valves and fittings shall be deducted as follows:

(1) The valves and fittings from the control valve to the farthest sprinkler shall be counted.

(2) The equivalent length for each valve and fitting as shown in Table 10.4.3(b) , Table 10.4.3(c) , orTable 10.4.3(d) or Table 10.4.3(e) shall be determined and the values added to obtain the totalequivalent length for each pipe size.

(3) The equivalent length for each size shall be multiplied by the pressure loss associated with the pipematerial and the values totaled.

In multilevel buildings, the steps in 10.4.3 (1) through 10.4.3 (8) shall be repeated to size piping foreach floor.

If the remaining pressure is less than the operating pressure established by the testing laboratory for thesprinkler being used, the sprinkler system shall be redesigned.

If the remaining pressure is higher than required, smaller piping shall be permitted to be used wherejustified by calculations.

The remaining piping shall be sized the same as the piping up to and including the farthest sprinklerunless smaller pipe sizes are justified by calculations.

A.8.2.5

The objective is to position sprinklers so that the response time and discharge are not unduly affected byobstructions such as ceiling slope, beams, light fixtures, or ceiling fans. The rules in this section, whiledifferent from the obstruction rules of NFPA 13, provide a reasonable level of life safety while maintainingthe philosophy of keeping NFPA 13D relatively simple to apply and enforce.

Fire testing has indicated the need to wet walls in the area protected by residential sprinklers at a levelcloser to the ceiling than that accomplished by standard sprinkler distribution. Where beams, light fixtures,sloped ceilings, and other obstructions occur, additional residential sprinklers are necessary to achieveproper response and distribution. In addition, for sloped ceilings, higher flow rates could be needed.Guidance should be obtained from the manufacturer.

A series of 33 full-scale tests were conducted in a test room with a floor area of 12 ft × 24 ft (3.6 m × 7.2 m)to determine the effect of cathedral (sloped) and beamed ceiling construction, and combinations of both, onfast-response residential sprinkler performance. The testing was performed using one pendent-typeresidential sprinkler model, two ceiling slopes (0 degrees and 14 degrees), and two beam configurations ona single enclosure size. In order to judge the effectiveness of sprinklers in controlling fires, two baselinetests, in which the ceiling was smooth and horizontal, were conducted with the pendent sprinklers installedand with a total water supply of 26 gpm (98 L/min) as required by this standard. The results of the baselinetests were compared with tests in which the ceiling was beamed or sloped, or both, and two pendentsprinklers were installed with the same water supply. Under the limited conditions used for testing, thecomparison indicates that sloped or beamed ceilings, or a combination of both, represent a seriouschallenge to the fire protection afforded by fast-response residential sprinklers. However, further tests withbeamed ceilings indicated that fire control equivalent to that obtained in the baseline tests can be obtainedwhere one sprinkler is centered in each bay formed by the beams and a total water supply of 36 gpm (136L/min) is available. Fire control equivalent to that obtained in the baseline tests was obtained for thesmooth, sloped ceiling tests where three sprinklers were installed with a total water supply of 54 gpm (200L/min). In a single smoldering-started fire test, the fire was suppressed.

Small areas created by architectural features such as planter box windows, bay windows, and similarfeatures can be evaluated as follows: Where no additional floor area is created by the architecturalfeature, no additional sprinkler protection is required.

Where additional floor area is created by an architectural feature, no additional sprinkler protection isrequired, provided all of the following conditions are met:

(1) The floor area does not exceed 18 ft 2 (1.7 m 2 ).

(2) The floor area is not greater than 2 ft (0.65 m) in depth at the deepest point of the architecturalfeature to the plane of the primary wall where measured along the finished floor.

(3) The floor area is not greater than 9 ft (2.9 m) in length where measured along the plane of theprimary wall.

Measurement from the deepest point of the architectural feature to the sprinkler should not exceed themaximum listed spacing of the sprinkler. The hydraulic design is not required to consider the area createdby the architectural feature.

Where the obstruction criteria established by this standard are followed, sprinkler spray patterns will notnecessarily get water to every square foot of space within a room. As such, a sprinkler in a room withacceptable obstructions as outlined in this standard might not be capable of passing the fire test (specifiedby ANSI/UL 1626, Residential Sprinklers for Fire-Protection Service, and other similar laboratory standards)if the fire is started in one of these dry areas. This occurrence is not to be interpreted as a failure of thesprinkler. The laboratory fire tests are sufficiently challenging to the sprinkler without additional obstructionsas a safety factor to account for the variables that actually occur in dwellings, including acceptableobstructions to spray patterns.

The rules on 8.2.5.1 and 8.2.5.2 were developed from a testing series conducted by the National FireSprinkler Association and The Viking Corporation that included fire modeling, sprinkler response tests,sprinkler distribution tests, and full-scale fire tests (Valentine and Isman, Interaction of ResidentialSprinklers, Ceiling Fans and Similar Obstructions, National Fire Sprinkler Association, November 2005).This test series, along with additional industry experience, shows that a difference exists betweenobstructions that are tight to the ceiling and obstructions that hang down from the ceiling, allowing sprayover the top. Residential sprinklers require high wall wetting, which means that they tend to spray overobstructions that hang down from the ceiling. The test series showed that the fan blades were notsignificant obstructions and that as long as the sprinkler was far enough from the fan motor housing


40 of 50 5/21/2014 9:34 AM

(measured from the center of the housing), the sprinkler could control a fire on the other side of the fan in asmall room. In larger rooms, the sprinkler will need to be augmented by additional sprinklers on the otherside of the fan. The test series showed that the fan on low or medium speed did not make a significantdifference in sprinkler performance. On high speed (pushing air down), the fan did impact sprinklerperformance, but fire control was still achieved in small rooms. In larger rooms, it is expected that additionalsprinklers would be installed. The test series also showed that the fan blowing down was more significantthan the fan pulling air up.

The rules in 8.2.5.6 were developed from years of experience with obstruction rules and an additional testseries conducted by the National Fire Sprinkler Association with the help of Tyco International (Valentineand Isman, Kitchen Cabinets and Residential Sprinklers, National Fire Sprinkler Association, November2005), which included fire modeling, distribution tests, and full-scale fire tests. The test series showed thatpendent sprinklers definitely provide protection for kitchens, even for fires that start under the cabinets. Theinformation in the series was less than definitive for sidewall sprinklers, but distribution data show thatsprinklers in the positions in this standard provide adequate water distribution in front of the cabinets andthat sidewall sprinklers should be able to control a fire that starts under the cabinets. When protectingkitchens or similar rooms with cabinets, the pendent sprinkler should be the first option. If pendentsprinklers cannot be installed, the next best option is a sidewall sprinkler on the opposite wall from thecabinets, spraying in the direction of the cabinets. The third best option is the sidewall sprinkler on thesame wall as the cabinets on a soffit flush with the face of the cabinet. The last option should be puttingsprinklers on the wall back behind the face of the cabinet because this location is subject to being blockedby items placed on top of the cabinets. It is not the intent of the committee to require sprinklers to beinstalled under kitchen cabinets.


Based upon Public Comment 22 which would move language regarding architectural features to the body of the standard, the annex language should be removed from the annex.

Public Comment No. 2-NFPA 13R-2014 [ Global Input ]

In Fig. A.5.4.2(a), there is no mention of the recommended depth of insulation above the pipe. (Theinsulation under the pipe does not contribute to freeze protection, in fact it hinders it.)

The same comment applies to Fig. A.5.4.2(b). The caption for this figure states “For areas havingtemperatures 0 F (-18 C) or lower…”. There is no mention of the thickness of the added batt.

In Fig. A.5.4.2(c), the words “As an alternative” do not make sense. Stuffing insulation in the holes in thejoists is not an alternative to drilling holes in the joist. Also, for temperatures of 0 F (-18 C) or lower thisfigure should also include mention of if an additional batt of insulation over the joists as described in Fig.A.5.4.2(b).

In Fig. A.5.4.2(f), there is no mention of the recommended depth of insulation above the tent.Type your content here ...


My proposed changes would provide more detailed guidance for freeze protection in Figs. A.5.4.2(a) thru (f)

5.1.1.2 Replacing Sprinklers

Where replacing residential sprinklers manufactured prior to 2003, installed using a design density lessthan 0.05 gpm/ft² (204 mm/min), and that are no longer available from the manufacturer, a residentialsprinkler with an equivalent K-factor (± 5%) shall be permitted to be used provided the currently listedcoverage area for the replacement sprinkler is not exceeded.

A.5.1.1.2

It is recognized that the flow and pressure available to the replacement sprinkler might be less than itscurrent flow and pressure requirement.


This language allows some flexibility when replacing sprinklers that may have been painted. Similar language will be submitted to NFPA 13 and NFPA 25. Many AHJ's look back to the installation standard when sprinklers are replaced. This is why it is beneficial to have this language in the installation standards as well as NFPA 25.

Pre-Engineered Systems.

Where listed pre-engineered systems are installed, they shall be installed within the limitations that havebeen established by the testing laboratories.


Currently NFPA 13D allows pre-engineered systems to be installed as an acceptable alternative. Under the definition of pre-engineered, the systems must have been successfully tested to the appropriate hazard. Allowing alternate systems and new technologies through sections 1.4 and 1.6 of this standard, requires engineering proof that the alternative is equal or better protection than what is in the standard. Often obtaining engineering support or approval can be difficult and expensive. This would open it up to being approved under standard review from an engineer or authority having jurisdiction. I also believe that this is also a correlating issue from 13D.

During the First Draft, the committee refused to remove the allowance to use QR sprinklers in dwelling units (Maximum of 4 per Dwelling Unit total). If the committee feels that QR sprinklers are adequate for protection, there should not be a 4 sprinkler maximum. The QR sprinklers will have a minimum .10 density and the calculations will be in accordance with NFPA 13.

Additional Proposed Changes

File Name Description Approved

Computer_Modeling_of_Closet.pdf Computer modeling of closet with residential sprinklers


Small closets, especially those housing mechanical equipment, frequently contain obstructions that make it difficult to place sprinklers within 12 inches of the ceiling. Allowing residential sprinklers to be located further down would allow adequate sprinkler protection of these small closets while avoiding ceiling level obstructions such as ducts and pipes. Based upon CFAST Computer Fire Model, an analysis was performed comparing the performance of sprinklers located 6 inches down from a ceiling in a small room to the performance of sprinklers 18 inches down from the ceiling in an even smaller closet. Based upon this analysis it appears that residential sprinklers 18 inches down from the ceiling in a closet up to 400 ft3 react to a fire at least as quickly as residential sprinklers 6 inches down from a ceiling in a small room. Using equivalency concepts, residential sprinklers could be allowed to be installed within 18 inches of the ceiling in small closets. This analysis is included in this public comment.

Computer Modeling of Closet with Residential Sprinkler 18 Inches from Ceiling

This analysis uses the CFAST Computer Fire Model to compare the performance of sprinklers 6

inches down from the ceiling in a small room to the performance of sprinklers 18 inches down

from the ceiling in an even smaller closet.

Baseline Room: 15 ft x 15 ft x 8 ft





All sprinklers 6 inches from ceiling


Closet: 7 ft x 7 ft x 8 ft (392 ft

important parts of the heat release due to sprinkler activation time)

Results

The following table compares the activation time of the sprinklers in the small room to that of

the sprinklers in the even smaller closet:

Sprinkler Activation Time in

Small Room (Figure 1)

Activation Time in Closet (Figure 2)




Conclusions

Given this fire location and these three sprinkler locations, it would appear that residential

sprinklers 18 inches down from the ceiling in a closet up to 400 ft3 react to a fire at least as

quickly as residential sprinklers 6 inches down from a ceiling in a small room. Using

equivalency concepts, residential sprinklers could be allowed to be installed within 18 inches of

the ceiling in small closets.

Prior to making any final determination, other combinations of fire size, fire location, and

sprinkler location should be analyzed in the same manner.

New 6.5.4

Sprinkler-Protected Glazing.

Where sprinklers are used in combination with glazing as an alternative to a required fire-rated wall orwindow assembly, the sprinkler-protected assembly shall comply with the following:

(1) Sprinklers shall be listed as specific application window sprinklers.

(2) Sprinklers shall be supplied by a wet-pipe system.

(3) Glazing shall be heat-strengthened or tempered and shall be fixed.

(4) Where the assembly is required to be protected from both sides, sprinklers shall be installed on bothsides of the glazing.

(5) The use of sprinkler-protected glazing shall be limited to non-load-bearing walls.

(6) The glazed wall assembly shall not have any horizontal members that would interfere with uniformdistribution of water over the surface of the glazing, and there shall be no obstructions between sprinklersand glazing that would obstruct water distribution.

Annex

It is not the intent of this section to apply to sprinkler protection of glass atrium enclosures, pedestrianwalkways, which are permitted by NFPA 101, or model building codes to be protected by standard spraysprinklers installed in accordance with the special provisions set forth in those codes for atriumconstruction.


The proposed text was accepted as a First Revision but later removed by the TCC. The language previously approved by the 13R has also been submitted to the 13 committee as a comment.

6.11.6 Fire department connections shall have an approved method to deter unauthorized removalof the FDC.


NFPA 13R is a design and installation standard and as such does address the security, protection, and assurance that the various components of required sprinkler systems will function properly when needed. This is seen in various sections including: • Sprinklers subject to mechanical injury shall be protected...,• Requiring approved plugs and caps to protect fire department connections from blockage and debris, In order to assure that fire department connections are present and operate properly in the event of fire they must be protected from theft or any unauthorized removal. Since the FDC is located outside of the protected structure they are more susceptible to theft than any other component. Theft of FDC’s has and is occurring nationwide and many times goes undetected until a fire when the fire department discovers they cannot pump into the system. This new section would allow the AHJ to approve different methods of deterring unauthorized removal of the FDC ranging from the use of locking methods to warning signage.

Fire department connections shall be permitted to connect to the underground piping dedicated to thesprinkler system where the pipe is rated for a pressure of at least 175 psi . Where the underground pipe isnonmetallic, the pressure rating shall be based on a temperature of at least 100 degrees Fahrenheit.


As NFPA 13R allows the underground piping to be any material acceptable under the plumbing code, when adding a FDC connection to this underground, the piping material must rated for 175 psi.

A.1.1


19 of 31 5/21/2014 9:36 AM

Revisions to paragraph A.1.1 and A.7.2 are proposed as follows:

1. Replace the first 4 paragraphs of the 2013 edition of NFPA 13R Annex Note A.1.1

with new text as indicated below.

A.1.1 NFPA 13R is appropriate for use as an

alternativeoption to NFPA 13 only in those

residential occupancies, as defined in this standard, up to and including four

aboveground stories in height, and limited to buildings that are 60 ft (18 m) or less in

height above grade plane, which is consistent with limits established by model

building codes for buildings of Type V construction. The height of a building above

grade plane is determined by model building codes, which base the height on

the average height of the highest roof surface above grade plane. For further

information on the building height 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.

A building's height is determined in accordance with the applicable building code,

which will have its own methods for determining building and story heights. Under

the IBC and NFPA 101/5000 Codes, an NFPA 13R sprinkler system is permitted in a

residential occupancy where the building is limited to four stories above grade plane

(See 2012 NFPA 101 Section 30.3.5.2, 2012 NFPA 5000 Section 25.3.5.3 and 2012

IBC Section 903.3.1.2). Also, IBC and NFPA 5000 limit the height of this residential

occupancy to no more than 60 ft (18m) in height above grade plane (See 2012

NFPA 5000 Section 7.5.2 and 2012 IBC Section 504.2). Such buildings sprinklered

in accordance with NFPA 13R are permitted to have basement(s) below the grade

plane. The model building codes do not consider stories below the grade plane in

the determination of a buildings height.

It is the intent of this standard that if NFPA13R is appropriate for use, it be applied as

described in the following paragraphs.

There are model building code provisions, where portions of a structure are above

and below a three hour fire rated horizontal assembly, that consider the buildings

above and below the three hour fire rated horizontal assembly as separate and

distinct buildings (See 2012 NFPA 5000, Section 7.4.3.6.5 and 2012 IBC Section

510.2). In such types of structures (commonly called “pedestal/podium” design),

where the residential occupancy above the three hour fire rated horizontal assembly

is considered as a separated building(s) by the applicable building code, NFPA 13R

is permitted when the residential building(s) are a maximum of 4 stories above the

fire-rated horizontal separation, and such buildings are limited to 60 ft (18 m) or less

in height above the grade plane. See Figure A.1.1 for an example of a

pedestal/podium type structure.

Figure A.1.1 Example of a “pedestal/podium” type structure (Exhibit 7.4 from

Supplement 4 of 2013 Residential Sprinkler System Handbook)

It is recognized that accessory or incidental occupancies, as defined by the

applicable building code, related to the operations of the residential occupancy will

exist within that residential occupancy. Such accessory or incidental occupancies


20 of 31 5/21/2014 9:36 AM

would be considered ancillary to the predominant or main occupancy (residential) of

the building and subject to the provisions of the predominant or main occupancy.

For instance see Section 6.1.14.1.3 of the 2012 NFPA 101 and similar provisions in

many local building/model building codes (See 2012 NFPA 5000 Sections 6.2.1.3,

6.2.1.4 & 6.2.1.5, and 2012 IBC Sections 508.2 & Section 509). Use of NFPA13R

throughout the entire building including related accessory or incidental occupancies

such as parking garages/areas, community laundry rooms, clubhouses, exercise

facilities, tenant storage spaces, maintenance rooms, storage rooms, leasing offices,

lobbies, community gathering spaces, small conference rooms, small gift shops, and

so forth would be permitted. Note that for these incidental or accessory

occupancies, it is the intent of NFPA 13R to reference the sprinkler discharge (flow

and pressure), number of design sprinklers, and position of sprinkler (distance from

walls, ceilings, and other sprinklers) requirements of NFPA 13. It is not the intent to

apply other rules from NFPA 13, such as sprinkler coverage of combustible

concealed spaces, hose stream demand, and water supply duration. See section

7.2 and associated annex.

For a building containing multiple occupancies utilizing the “separated” occupancy

provisions in accordance with the applicable building code, residential occupancies

are within the scope of NFPA 13R provided the building is not more than 4 stories in

height, does not exceeding 60' in height above grade plane, and the residential

occupancy is separated from the other occupancies in accordance with the

“separated” occupancy requirements of the applicable building code (For example

see 2012 NFPA 5000 Sections 6.2.2.3 & 6.2.4, and 2012 IBC Section 508.4). In

such cases, NFPA 13R can be used in the residential occupancies and NFPA 13 is

to be used in the other non-residential occupancies in the building.

A building containing multiple occupancies utilizing the “non-separated” occupancy

provisions of the applicable building code is not within the scope of NFPA 13R. For

such a building, the applicable building code typically requires the use of an NFPA

13 system throughout the building. Residential buildings containing accessory or

incidental occupancies as described above are not considered multiple occupancy

buildings.

Residential occupancies in a building greater than four stories in height, or in a

building exceeding 60 ft (18m) in height above the grade plane, are not within the

scope of NFPA 13R.

A decision to use NFPA 13R in a building containing multiple (mixed) occupancies,

as defined in the model building codes and NFPA 101, can inherently impose

restrictions on the building, which should be made known at the time of design and

construction. Architects, engineers, and code officials are cautioned that the locally

adopted statutes, ordinances and codes that require sprinklers for certain

occupancies or buildings may also provide certain compensatory building features

(commonly called “trade-offs”) for the installation of the fire sprinkler system. If such

“sprinkler trade-offs” are given in these adopted statutes, ordinances and codes for

only buildings sprinklered throughout in accordance with NFPA 13, then to permit

such occupancies or buildings to apply such “trade-offs”, the occupancies or


21 of 31 5/21/2014 9:36 AM

buildings would be required to be sprinklered in accordance with NFPA 13, not

NFPA 13R. (For example see 2012 NFPA 5000 Sections 7.6.2.2, 7.4.3.6.5(4b), and

Footnote “†” to Tables 6.2.4.1(a) & (b); and 2012 IBC Sections 504.2, 510.2(6), and

Footnotes “S” and “NS” to Table 508.4).

Decisions to use passive (fire resistive) construction to provide separation between

the residential occupancy having an NFPA 13R sprinkler system and adjacent

occupancies will likely not be permitted to have reductions in the required hourly

rating which would be permitted to be applied for buildings having an NFPA 13

sprinkler system installed throughout all portions of the building, including residential.

In addition, area and height increases above the base (tabular) values defined by the

model building codes for the various occupancies would not be applicable for

buildings having an NFPA 13R sprinkler system in the residential occupancy portion

(s) of the building. These height and area increases are typically limited to buildings

having NFPA 13 sprinkler systems installed throughout in accordance with the model

building code.

In summary, the determination of the applicable sprinkler standard(s) required for the

occupancies in a building will be ultimately determined through the locally adopted

statutes, ordinances and codes.

2. Revise Annex Note A.7.2 as follows:

A.7.2 It is only the intent of NFPA 13R to reference the sprinkler discharge (flow and

pressure), number of design sprinklers, and position of sprinklers (distance from

walls, ceilings, and other sprinklers) requirements of NFPA 13. Other rules from

NFPA 13 such as sprinklering of combustible concealed spaces, hose stream

demand, and water supply duration are not intended to be referenced by Section

7.2. It is also the intent of Section 7.2 to apply to those systems or portions of

systems that are outside the dwelling unit but have been determined to be

considered residential, accessory, or incidental to residential, and within the scope of

this standard. (Also see A.1.1.)

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 authority


22 of 31 5/21/2014 9:36 AM

having 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.

Accept the Committee Input. Telling the user to simply go to the building code is a disservice. Many Fire Officials are not Building Code experts. This section gives great guidance on when 13R is applicable.
