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 system network of underground and overhead piping designed in accordance with fire protection engineering standards . The installation includes one or more automatic water supplies that includes a water supply source, a water control valve, a waterflow alarm, and a drain and is commonly activated by heat from a fire, discharging water over the fire area . The portion of the sprinkler system aboveground above ground is a network of specially specifically sized or hydraulically designed piping installed in a building, structure, or area, generally overhead, and to which sprinklers are attached in a systematic pattern. The system is usually commonly 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 component within this standard.
Statement of Problem and Substantiation for Public Comment This change would permit consistancy with NFPA13. The additional anex material serves to clarify that the waterflow switch is not a required system component. Related Item Public Input No. 6-NFPA 13D-2012 [Section No. 3.3.11.8]

Statement of Problem and Substantiation for Public Comment 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.

Public Comment No. 26-NFPA 13D-2014 [ Section No. 5.1.1.1 ]
5.1.1.1 * Where a sprinkler is removed from a fitting or welded outlet, it shall not be reinstalled except as permitted by 5.1.1.1.1 . 5.1.1.1.1 * Dry sprinklers shall be permitted to be reinstalled, where they are not removed by applying torque at the point where the sprinkler is attached to the barrel. its listing.
Statement of Problem and Substantiation for Public Comment Regarding the change proposed by FR #2, NFPA's Building Code Development Committee believes consideration should at least be given when the sprinkler manufacturer has specified a removal method as is explained in Thomas Deegan’s negative vote comments. This makes the provision more succinct. Note that this is related to our Public Comment relocating the Annex material in A5.1.1.1.1 to A5.1.1.1.

5.3* Underground Pipe. 5.3.1 Type. Any type of pipe or tube acceptable under the applicable plumbing code for underground supply pipe shall be acceptable as an underground supply for a fire sprinkler system when 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 shall be buried not less than 1 ft (0.3 m) below the frost line for the locality. In those locations where frost is not a factor, the depth of cover shall be not less than 2½ ft (0.8 m) to prevent mechanical damage. 5.3.2 .2 The depth of cover over water pipes shall be determined by the maximum depth of frost penetration in the locality where the pipe is laid. The depth of cover shall be measured from the top of the pipe to finished grade, and due consideration shall always be given to future or final grade and nature of soil. 5.3.3 Protection Against Damage. Unless specified otherwise by the applicable plumbing code, the pipe shall be protected from mechanical and physical damage.
Statement of Problem and Substantiation for Public Comment 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 similar features shall be evaluated as follows: (1) Where no additional floor area is created by the architectural feature, no additional sprinkler protection is required. (2) Where additional floor area is created by an architectural feature, no additional sprinkler protection is required, provided all of the following conditions are met: (a)
2 2 The floor area shall not exceed 18 ft (1.7 m ).
(b) The floor area shall not be greater than 2 ft (0.61 m) in depth at the deepest point of the architectural 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 the primary wall. (d) Measurement from the deepest point of the architectural feature to the sprinkler shall not exceed the maximum listed spacing of the sprinkler. (3) The hydraulic design is not required to consider the area created by the architectural feature.
Statement of Problem and Substantiation for Public Comment 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.

Statement of Problem and Substantiation for Public Comment 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) Fire: Fairly slow growing fire Center of the room/closet See Figure 3

Figure 3 – Heat Release Rate for Fire (Note that the first 600 seconds are the only 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 1 2 3
Activation Time in Activation Time Small Room in Closet (Figure 1) (Figure 2) 510 seconds 500 seconds 530 seconds 500 seconds 510 seconds 500 seconds
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.

Unless the pipe size is in accordance with the prescriptive pipe sizing method of 10.4.9 , pipe shall be sized by hydraulic calculations in accordance with the methods described in NFPA 13, with the manufacturer's listed installation instructions, with 10.4.4 , or with the following general method for straight-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 be determined that the flow allowed by the water meter meets or exceeds the system demand and that the total 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 sized using 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's rated continuous flow. Higher pressure losses specified by the manufacturer shall be used in place of those specified in Table 10.4.3(a) . Lower pressure losses shall be permitted to be used where supporting data are provided by the meter manufacturer. 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 losses from the city main to the inside control valve shall be deducted by multiplying the pressure loss associated with the pipe material by the total length(s) of pipe in feet (meters). Pressure loss for piping within the building shall be deducted by multiplying the pressure loss associated with 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) , or Table 10.4.3(d) or Table 10.4.3(e) shall be determined and the values added to obtain the total equivalent length for each pipe size. (3) The equivalent length for each size shall be multiplied by the pressure loss associated with the pipe material 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 for each floor. If the remaining pressure is less than the operating pressure established by the testing laboratory for the sprinkler being used, the sprinkler system shall be redesigned. If the remaining pressure is higher than required, smaller piping shall be permitted to be used where justified by calculations. The remaining piping shall be sized the same as the piping up to and including the farthest sprinkler unless smaller pipe sizes are justified by calculations.

(1) The system flow rate shall be established in accordance with Sections 10.1 and 10.2, and it shall be determined that the flow allowed by the water meter meets or exceeds the system demand and that the total demand flow does not exceed the maximum flow allowed by the piping system components. (2) The water pressure in the street shall be determined. (3) Pipe sizes shall be selected. (4) *Pressure loss for a water meter, if any, shall be determined and deducted using one of the following: (5) Table 10.4.4(a) shall be permitted to be used, even where the sprinkler demand flow exceeds the meter's rated continuous flow. (6) Higher pressure losses specified by the manufacturer shall be used in place of those specified in Table 10.4.4(a). (7) Lower pressure losses shall be permitted to be used where supporting data are provided by the meter manufacturer.
(8) Pressure loss for elevation shall be deducted as follows: (9) Building height above street (ft) × 0.433 = pressure loss (psi) (10) Building height above street (m) × 0.098 = pressure loss (bar)
(11) *Pressure losses from the city main to the inside control valve shall be deducted by multiplying the pressure loss associated with the pipe material by the total length(s) of pipe in feet (meters). (12) Pressure loss for piping within the building shall be deducted by multiplying the pressure loss associated with the pipe material by the total length(s) of pipe in feet (meters). (13) Pressure loss for valves and fittings shall be deducted as follows: (14) The valves and fittings from the control valve to the farthest sprinkler shall be counted. (15) The equivalent length for each valve and fitting as shown in Table 10.4.4(b), Table 10.4.4(c), or Table 10.4.4(d) or Table 10.4.4(e) shall be determined and the values added to obtain the total equivalent length for each pipe size. (16) The equivalent length for each size shall be multiplied by the pressure loss associated with the pipe material and the values totaled.
(17) In multilevel buildings, the steps in 10.4.4(1) through 10.4.4(8) shall be repeated to size piping for each floor. (18) If the remaining pressure is less than the operating pressure established by the testing laboratory for the sprinkler being used, the sprinkler system shall be redesigned. (19) If the remaining pressure is higher than required, smaller piping shall be permitted to be used where justified by calculations. (20) The remaining piping shall be sized the same as the piping up to and including the farthest sprinkler unless smaller pipe sizes are justified by calculations.

The objective is to position sprinklers so that the response time and discharge are not unduly affected by obstructions such as ceiling slope, beams, light fixtures, or ceiling fans. The rules in this section, while different from the obstruction rules of NFPA 13, provide a reasonable level of life safety while maintaining the 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 level closer 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 achieve proper 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, on fast-response residential sprinkler performance. The testing was performed using one pendent-type residential sprinkler model, two ceiling slopes (0 degrees and 14 degrees), and two beam configurations on a single enclosure size. In order to judge the effectiveness of sprinklers in controlling fires, two baseline tests, in which the ceiling was smooth and horizontal, were conducted with the pendent sprinklers installed and with a total water supply of 26 gpm (98 L/min) as required by this standard. The results of the baseline tests were compared with tests in which the ceiling was beamed or sloped, or both, and two pendent sprinklers were installed with the same water supply. Under the limited conditions used for testing, the comparison indicates that sloped or beamed ceilings, or a combination of both, represent a serious challenge to the fire protection afforded by fast-response residential sprinklers. However, further tests with beamed ceilings indicated that fire control equivalent to that obtained in the baseline tests can be obtained where one sprinkler is centered in each bay formed by the beams and a total water supply of 36 gpm (136 L/min) is available. Fire control equivalent to that obtained in the baseline tests was obtained for the smooth, sloped ceiling tests where three sprinklers were installed with a total water supply of 54 gpm (200 L/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 similar features can be evaluated as follows: Where no additional floor area is created by the architectural feature, no additional sprinkler protection is required. Where additional floor area is created by an architectural feature, no additional sprinkler protection is required, 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 architectural feature 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 the primary wall.
Measurement from the deepest point of the architectural feature to the sprinkler should not exceed the maximum listed spacing of the sprinkler. The hydraulic design is not required to consider the area created by the architectural feature. Where the obstruction criteria established by this standard are followed, sprinkler spray patterns will not necessarily get water to every square foot of space within a room. As such, a sprinkler in a room with acceptable obstructions as outlined in this standard might not be capable of passing the fire test (specified by 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 the sprinkler. The laboratory fire tests are sufficiently challenging to the sprinkler without additional obstructions as a safety factor to account for the variables that actually occur in dwellings, including acceptable obstructions 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 Fire Sprinkler 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 Residential Sprinklers, Ceiling Fans and Similar Obstructions, National Fire Sprinkler Association, November 2005). This test series, along with additional industry experience, shows that a difference exists between obstructions that are tight to the ceiling and obstructions that hang down from the ceiling, allowing spray over the top. Residential sprinklers require high wall wetting, which means that they tend to spray over obstructions that hang down from the ceiling. The test series showed that the fan blades were not significant obstructions and that as long as the sprinkler was far enough from the fan motor housing

(measured from the center of the housing), the sprinkler could control a fire on the other side of the fan in a small room. In larger rooms, the sprinkler will need to be augmented by additional sprinklers on the other side of the fan. The test series showed that the fan on low or medium speed did not make a significant difference in sprinkler performance. On high speed (pushing air down), the fan did impact sprinkler performance, but fire control was still achieved in small rooms. In larger rooms, it is expected that additional sprinklers would be installed. The test series also showed that the fan blowing down was more significant than the fan pulling air up. The rules in 8.2.5.6 were developed from years of experience with obstruction rules and an additional test series conducted by the National Fire Sprinkler Association with the help of Tyco International (Valentine and Isman, Kitchen Cabinets and Residential Sprinklers, National Fire Sprinkler Association, November 2005), which included fire modeling, distribution tests, and full-scale fire tests. The test series showed that pendent sprinklers definitely provide protection for kitchens, even for fires that start under the cabinets. The information in the series was less than definitive for sidewall sprinklers, but distribution data show that sprinklers in the positions in this standard provide adequate water distribution in front of the cabinets and that sidewall sprinklers should be able to control a fire that starts under the cabinets. When protecting kitchens or similar rooms with cabinets, the pendent sprinkler should be the first option. If pendent sprinklers cannot be installed, the next best option is a sidewall sprinkler on the opposite wall from the cabinets, spraying in the direction of the cabinets. The third best option is the sidewall sprinkler on the same wall as the cabinets on a soffit flush with the face of the cabinet. The last option should be putting sprinklers on the wall back behind the face of the cabinet because this location is subject to being blocked by items placed on top of the cabinets. It is not the intent of the committee to require sprinklers to be installed under kitchen cabinets.

The objective is to position sprinklers so that the response time and discharge are not unduly affected by obstructions such as ceiling slope, beams, light fixtures, or ceiling fans. The rules in this section, while different from the obstruction rules of NFPA 13, provide a reasonable level of life safety while maintaining the 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 level closer 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 achieve proper 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, on fast-response residential sprinkler performance. The testing was performed using one pendent-type residential sprinkler model, two ceiling slopes (0 degrees and 14 degrees), and two beam configurations on a single enclosure size. In order to judge the effectiveness of sprinklers in controlling fires, two baseline tests, in which the ceiling was smooth and horizontal, were conducted with the pendent sprinklers installed and with a total water supply of 26 gpm (98 L/min) as required by this standard. The results of the baseline tests were compared with tests in which the ceiling was beamed or sloped, or both, and two pendent sprinklers were installed with the same water supply. Under the limited conditions used for testing, the comparison indicates that sloped or beamed ceilings, or a combination of both, represent a serious challenge to the fire protection afforded by fast-response residential sprinklers. However, further tests with beamed ceilings indicated that fire control equivalent to that obtained in the baseline tests can be obtained where one sprinkler is centered in each bay formed by the beams and a total water supply of 36 gpm (136 L/min) is available. Fire control equivalent to that obtained in the baseline tests was obtained for the smooth, sloped ceiling tests where three sprinklers were installed with a total water supply of 54 gpm (200 L/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 similar features can be evaluated as follows: Where no additional floor area is created by the architectural feature, no additional sprinkler protection is required. Where additional floor area is created by an architectural feature, no additional sprinkler protection is required, 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 architectural feature 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 the primary wall.
Measurement from the deepest point of the architectural feature to the sprinkler should not exceed the maximum listed spacing of the sprinkler. The hydraulic design is not required to consider the area created by the architectural feature. Where the obstruction criteria established by this standard are followed, sprinkler spray patterns will not necessarily get water to every square foot of space within a room. As such, a sprinkler in a room with acceptable obstructions as outlined in this standard might not be capable of passing the fire test (specified by 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 the sprinkler. The laboratory fire tests are sufficiently challenging to the sprinkler without additional obstructions as a safety factor to account for the variables that actually occur in dwellings, including acceptable obstructions 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 Fire Sprinkler 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 Residential Sprinklers, Ceiling Fans and Similar Obstructions, National Fire Sprinkler Association, November 2005). This test series, along with additional industry experience, shows that a difference exists between obstructions that are tight to the ceiling and obstructions that hang down from the ceiling, allowing spray over the top. Residential sprinklers require high wall wetting, which means that they tend to spray over obstructions that hang down from the ceiling. The test series showed that the fan blades were not significant obstructions and that as long as the sprinkler was far enough from the fan motor housing

(measured from the center of the housing), the sprinkler could control a fire on the other side of the fan in a small room. In larger rooms, the sprinkler will need to be augmented by additional sprinklers on the other side of the fan. The test series showed that the fan on low or medium speed did not make a significant difference in sprinkler performance. On high speed (pushing air down), the fan did impact sprinkler performance, but fire control was still achieved in small rooms. In larger rooms, it is expected that additional sprinklers would be installed. The test series also showed that the fan blowing down was more significant than the fan pulling air up. The rules in 8.2.5.6 were developed from years of experience with obstruction rules and an additional test series conducted by the National Fire Sprinkler Association with the help of Tyco International (Valentine and Isman, Kitchen Cabinets and Residential Sprinklers, National Fire Sprinkler Association, November 2005), which included fire modeling, distribution tests, and full-scale fire tests. The test series showed that pendent sprinklers definitely provide protection for kitchens, even for fires that start under the cabinets. The information in the series was less than definitive for sidewall sprinklers, but distribution data show that sprinklers in the positions in this standard provide adequate water distribution in front of the cabinets and that sidewall sprinklers should be able to control a fire that starts under the cabinets. When protecting kitchens or similar rooms with cabinets, the pendent sprinkler should be the first option. If pendent sprinklers cannot be installed, the next best option is a sidewall sprinkler on the opposite wall from the cabinets, spraying in the direction of the cabinets. The third best option is the sidewall sprinkler on the same wall as the cabinets on a soffit flush with the face of the cabinet. The last option should be putting sprinklers on the wall back behind the face of the cabinet because this location is subject to being blocked by items placed on top of the cabinets. It is not the intent of the committee to require sprinklers to be installed under kitchen cabinets. Renumber first paragraph in 8.2.5.6, as 8.2.5.6.1 and move anex to 8.2.5.6.2 Small areas created by architectural features such as planter box windows, bay windows, and similar features shall be evaluated as follows: (1) Where no additional floor area is created by the architectural feature, no additional sprinkler protection is required. (2) Where additional floor area is created by an architectural feature, no additional sprinkler protection is required, 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 the architectural 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 the primary wall. (d) Measurement from the deepest point of the architectural feature to the sprinkler shall not exceed the maximum listed spacing of the sprinkler. (3) The hydraulic design is not required to consider the area created by the architectural feature.

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. (The insulation 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 having temperatures 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 the joists is not an alternative to drilling holes in the joist. Also, for temperatures of 0 F (-18 C) or lower this figure 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 ...

Public Comment No. 5-NFPA 13R-2014 [ Global Input ]
This reformatting addresses the Committee Input #28, and the Committee’s First Revision #11 & #12 NFPA 13R-2013 which moved and correlated the relocation of 6.4.7 to 6.2.2.5 . There are no technical changes to the existing requirements in the Code. 6.2.2 Outside Dwelling Units. 6.2.2.1 Sprinklers outside the dwelling units shall be quick response, except as permitted by 6.2.2.2. The sprinkler design criteria shall be in accordance with Chapter 7. All sprinklers used outside of the dwelling units shall be in accordance with 6.2.2. 6.2.2.2 Sprinklers outside the dwelling units shall be quick response, except as allowed by 6.2.2.3 and 6.2.2.4. (Deleted because it is now covered in 6.2.2.1) 6.4.7 Use of Residential Sprinklers Outside of Dwelling Units. (Relocating existing Section 6.4.7 which was moved to Section 6.4.2.2.5 and now moving to new Section 6.2.2.2 and modified as shown here.) 6.2.2.2 The following types of spaces shall be permitted to be protected by residential sprinklers in accordance with Section 7.1 unless otherwise noted: (1) Lobbies not in hotels and motels (2) Foyers (3) Corridors (4) Halls (5) Lounges (6) Ordinary hazard areas in accordance with Section 7.2.4.1 (7) Garages in accordance in accordance with Sections 7.3.3 and 7.3.3.1(1) (6 8) Other areas with fire loads similar to residential fire loads 6.2.2.3 Residential sprinklers shall be permitted to be used in garages that are accessible only from and directly connected to a single dwelling unit. (Deleted because it is already covered under 6.2.2.2(7) above, 7.3.3 & 7.3.3.1) (Move 6.2.2.4 to New 7.2.4.1) 6.2.2.4 Residential sprinklers shall be permitted to be used in ordinary hazard areas that meet the following conditions: (1) The area is compartmented into 500 ft2 (46 m2) or less by 30-minute fire-rated construction. (2) The sprinklers are spaced at 130 ft2 (12 m2) per sprinkler. (3) Openings have a lintel at least 8 in. (203 mm) in depth. (4) The total area of openings, excluding any overhead garage doors that open to the exterior, does not exceed 50 ft2 (4.6 m2) for each compartment. (5) Discharge densities are in accordance with NFPA 13 for ordinary hazard. 7.2* Design Criteria — Outside Dwelling Unit. 7.2.1 Areas outside the dwelling unit shall comply with Section 7.2. 7.2.2 7.2.4 The number of design sprinklers for a corridor or breezeway outside the dwelling unit shall include up to the four most hydraulically demanding adjacent sprinklers. (Moved existing Section 7.2.4 to new 7.2.2 because it also applies to not only quick response sprinkler design, but also residential sprinkler design. Therefore, did not need to reference in this section of Code [as reference in existing 7.2.2 in 2013 NFPA 13 shown below in new 7.2.3] since it applies to both quick-response and residential sprinklers.) 7.2.2 3 The design discharge and design area criteria for areas protected by quick-response sprinklers shall comply with NFPA 13 except as allowed by 7.2.2 3.1 and 7.2.4.

5.1.1.2 Replacing Sprinklers Where replacing residential sprinklers manufactured prior to 2003, installed using a design density less than 0.05 gpm/ft² (204 mm/min), and that are no longer available from the manufacturer, a residential sprinkler with an equivalent K-factor (± 5%) shall be permitted to be used provided the currently listed coverage 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 its current flow and pressure requirement.
Statement of Problem and Substantiation for Public Comment 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. Related Item Public Input No. 6-NFPA 13R-2012 [New Section after 5.1.1.1]

Public Comment No. 27-NFPA 13R-2014 [ New Section after 5.4 ]
Pre-Engineered Systems. Where listed pre-engineered systems are installed, they shall be installed within the limitations that have been established by the testing laboratories.
Statement of Problem and Substantiation for Public Comment 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. Related Item First Revision No. 3-NFPA 13R-2013 [Section No. 4.2]

Statement of Problem and Substantiation for Public Comment 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.

Sprinkler 1 2 3
Activation Time in Activation Time Small Room in Closet (Figure 1) (Figure 2) 510 seconds 500 seconds 530 seconds 500 seconds 510 seconds 500 seconds
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 removal of the FDC.
Statement of Problem and Substantiation for Public Comment 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.

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 alternative option 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 or incidental uses are often subject to special rules that may restrict the use of NFPA 13R. Refer to the adopted 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
5/21/2014 9:36 AM
National Fire Protection Association Report

http://submittals.nfpa.org/TerraViewWeb/ContentFetcher?commentPara...
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

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 in residential living rooms, kitchens, and bedrooms. The furnishings were arranged as typically found in dwelling 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 tests were conducted in a 14 ft (4.3 m) wide mobile home in Charlotte, North Carolina. Sprinkler systems designed and installed according to this standard are expected to prevent flashover within the compartment of origin where sprinklers are installed in the compartment. A sprinkler system designed and installed according to this standard cannot, however, be expected to completely control a fire involving fuel loads 2 2 that are significantly higher than average for dwelling units [10 lb/ft (49 kg/m )], configurations of fuels other than those with typical residential occupancies, or conditions where the interior finish has an unusually high flame spread index (greater than 225). To be effective, sprinkler systems installed in accordance with this standard need to open the sprinklers closest to the fire before the fire exceeds the ability of the sprinkler discharge to extinguish or control the fire. Conditions that allow the fire to grow beyond that point before sprinkler activation or that interfere with the quality of water distribution can produce conditions beyond the capabilities of the sprinkler system described in this standard. Unusually high ceilings or ceiling configurations that tend to divert the rising hot gases from sprinkler locations or change the sprinkler discharge pattern from its standard pattern can produce 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 spacing outside of dwelling unit, painting and finish of sprinklers, welding, etc.). If this standard does not specifically address a situation, NFPA 13 is a good resource that can be utilized by the installer and the authority

having jurisdiction for a solution. It is not the intent of this standard to require compliance with NFPA 13 when NFPA 13R is silent on a subject. Only AHJ approval should be required. Figure A.1.1(a) Bedroom.

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. Related Item Committee Input No. 33-NFPA 13R-2013 [Global Input]

An example of an open corridor or exterior corridor , stair, or breezeway is one that is exposed to the outside atmosphere (temperature). Another example is an exterior wraparound corridor that is typical in a two- to three-story motel.
