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 ...

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.

Resolution: Residential sprinklers are principally designed and developed for life safety. Commercial sprinklersare principally designed for property protection. Conditions may exist, like roof pitch or ceilingconstruction that present a challenge to residential sprinklers. In those cases, having the option ofusing a limited number of commercial spray sprinklers is desirable. The number of commercialsprinklers is limited to four. This limitation allows calculations to remain more simplistic since we arenot using an area design method and it also allows us to assure that we are using residentialsprinkler, and their inherent life safety characteristics like high wall wetting, as frequently as possible.

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 ft3)

3 sprinkler locations (see Figure 2)

o Sprinkler 1 – 2 ft from south and west walls

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

o Sprinkler 3 – 4 inches from south and east walls

All sprinklers 18 inches down from ceiling

All sprinklers RTI = 50 (metric units)

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.

Public Comment No. 12-NFPA 13R-2014 [ New Section after 6.11.5 ]

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.

Public Comment No. 13-NFPA 13R-2014 [ Section No. A.1.1 ]


20 of 33 9/4/2014 8:36 AM

A.1.1


21 of 33 9/4/2014 8:36 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


22 of 33 9/4/2014 8:36 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


23 of 33 9/4/2014 8:36 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


24 of 33 9/4/2014 8:36 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.
