Only the Style 15 or Style 20 Recessed Escutcheon is to be used for recessed pendent installations. The TYCO Series TY-FRB, 5.6 K-factor, Upright (TY313) and Pendent (TY323) Sprinklers gust be installed in accor- dance with this section. General Instructions Do not install any bulb -type sprinkler if the bulb is cracked or there is a loss of liquid from the bulb, With the sprin- kles' held horizontally, a small air bub- ble should be present. The diameter of the air bubble is approximately 1/16 inch (1,6 mm) for the 135°F (57"C) and 3/32 inch (2,4 mm) for the 28VF (141" ) temperature ratings. A leak -tight 112 inch RIPT sprinkler joint should be obtained by applying a min- imum to maximum torque of 7 to 14 ft. lbs. (9,5 to 19,0 N ). Higher levels of torque can distort the sprinkler Inlet with consequent leakage or impairment of the sprinkler. Do not attempt to compensate for insufficient adjustment in the Escutch- eon Plate by under- or over -tightening the sprinkler. Re -adjust the position of the sprinkler fitting to suit. Upright and pendent Sprinklers The Series TY-FRB Upright and Pen- dent Sprinklers must be installed in accordance with the following instructions. Step 1, Install Pendent sprinklers in the pendent position. Install upright sprin- kters in the upright position. Step 2. With pipe -thread sealant applied to the pure threads, hand - tighten the sprinkler into the sprinkler fitting. Step 3. Tighten the sprinkler into the sprinkler fitting using only the W Type 6 Sprinkler Wrench (Figure 2). With ref- erence to Figure 1, apply the W Type 6 Sprinkler Wrench to the wrench flats. Torque sprinklers 7 to 14 ft.-lbs. (9,5 to 19,0 Nm). Recessed Pendent Sprinklers The Series TY-FRB Recessed Pendent Sprinklers must be installed in accor- dance with the following instructions. Step A. After installing the Style 15 or Style 20 Mounting Plate over the sprin- kler threads, and with pipe -thread sealant applied to the pipe threads, hand -tighten the sprinkler into the sprinkler fitting. Step B. Tighten the sprinkler into the sprinkler fitting using only the W-Type 7 Recessed Sprinkler Wrench (Figure 3). With reference to Figure 1, apply the W Type 7 Recessed Sprinkler Wrench to the sprinkler wrench flats. Torque sprinklers 7 to 14 ft.-Ibs. (9,5 to 19,0 Nm). Step C. After ceiling installation and fin ishing, slide on the Style 15 or Style 20 Closure over the Series TY-FRB Sprin- kler and push the Closure over the Mounting Plate until its flange comes in contact with the ceiling. The TYCO Series TY-FRB, 5.6 K-factor, Upright (TY313) and Pendent (TY323) Sprinklers mast be maintained and ser- viced in accordance with this section. Before closing a fire protection system main control valve for maintenance work on the fire protection system that it controls, obtain permission to shut down the affected fire protection systems from the proper authorities and notify all personnel who may be affected by this action. Absence of the outer piece of an escutcheon, which is used to cover a clearance hole, can delay sprinkler operation in a fire situation. The owner must assure that the sprin- klers are not used for hanging any objects and that the sprinklers are only cleaned by means of gently dusting with a feather duster; otherwise, non - operation in the event of a fire or inad- vertent operation may result. Sprinklers which are found to be leak- ing or exhibiting visible signs of corro- sion must be replaced. Automatic sprinklers must never be painted, plated, coated, or other- wise altered after leaving the factory. 2-7/6" DIA. (73,0 mm) 2-1/4' DIA.

The Series LFII Dry Type Residential Recessed Pendent Sprinklers are typi- cally used for the following situations: • where sprinklers are required on dry pipe systems that are exposed to freezing temperatures; for example, sprinkler drops from unheated por- tions of buildings • where sprinklers and/or a portion of the connecting piping are exposed to freezing temperatures-, for example, sprinkler drops from wet systems into unheated areas • where sprinklers are used on systems that are seasonally drained to avoid freezing; for example, vacation areas The Series LFII Dry Type Residen- tial Recessed Pendent Sprinklers are intended for use in residential sprin- kler systems for one- and two-family dwellings and mobile homes per NFPA 13D, residential sprinkler systems for residential occupancies up to and in- cluding four stories in height per NFPA 13R; or, sprinkler systems for the resi- dential portions of any occupancy per NFPA 13. IMPORTANT Always refer to Technical Data Sheet TFP700 for the "INSTALLER WARNING" that provides cautions with respect to handling and instal- lation of sprinkler systems and com- ponents. Improper handling and installation can permanently dam- age a sprinkler system or its compo- nents and cause the sprinkler to fail to operate in a fire situation or cause it to operate prematurely. The Series LFII Dry Type Residential Recessed Pendent Sprinklers provide flexibility in adjusting sprinklers to the fixed pipe drops. The Recessed Es- cutcheon provides 1/4, inch (6,4 mm) of recessed adjustment or up to 112 inch (12,7 mm) of total adjustment from the flush mounting surface position. The Series LFII Dry Type Residential Recessed Pendent Sprinklers are de- signed with heat sensitivity and water characteristics proven to help in con- trolling residential fires and improving the chance for occupants to escape or be evacuated. Dry Pipe System Application The Series I -I'll Residential Pendent and Recessed Pendent Sprinklers of- fers a laboratory approved option for designing dry pipe residential sprinkler systems, whereas, most residential sprinklers are laboratory approved for wet systems only. Through extensive testing and as ref- erenced in U.S. Patent 7,712,543, it has been determined that the number of design sprinklers (hydraulic design area) for the Series LFII Residential Pendent and Recessed Pendent Sprin- klers (TY2235) need not be increased over the number of design sprinklers (hydraulic design area) as specified for wet pipe sprinkler systems, as is ac- customed for density/area sprinkler systems designed per NFPA 13. Consequently, the Series LFII Resi- dential Sprinklers offer the features of non -water filled pipe in addition to not having to increase the number of de- sign sprinklers (hydraulic design area) for systems designed to NFPA 13, 13D, or 13R. Non -water filled pipe will permit options for areas sensitive to freezing. 1 NOTICE The Series LFII Dry Type Residential Recessed Pendent Sprinklers (TY2235) described herein must be installed and maintained in compliance with this document and the applicable stan- dards of the National Fire Protection Association, in addition to the stan- dards of any authorities having juris- diction. Failure to do so may impair the performance of these devices. The owner is responsible for maintain- ing their fire protection system and de- vices in proper operating condition.

The glass Bulb contains a fluid that expands when exposed to heat. When the rated temperature is reached, the fluid expands sufficiently to shatter the glass Bulb to release the Bulb Seat. The system's water or air pressure is then able to unseat the Plug with Seal- ing Assembly. The Plug Spring turns the Plug with Sealing Assembly aside, allowing the sprinkler to activate and flow water. 0 ,. The TYCO RAPID RESPONSE Series LFII Dry Type Residential Recessed Pendent Sprinklers (fY2235) are UL Listed for installation in accordance with this section: Residential Sprinkler Design Guide When conditions exist that are out- side the scope of the criteria provided in this section, refer to the technical data sheet entitled Residential Sprin- kler Design Guide (TFP490) for the manufacturer's recommendations that may be acceptable to the local authority having jurisdiction. System Types Wet pipe and dry pipe systems may be utilized. Hydraulic Design (NFPA 13D and 13R) For systems designed to NFPA 13D or NFPA 13R, the minimum required sprinkler flow rate are given in Tables A or B as a function of temperature rat- ing and the maximum allowable cov- erage areas. The sprinkler flow rate is the minimum required discharge from each of the total number of "design sprinklers," as specified in NFPA 13D or NFPA 13R. The number of "design sprinklers" specified in NFPA 13D and 13R for wet pipe systems is to be ap- plied when designing dry pipe systems. Hydraulic Design (NFPA 13) For systems designed to NFPA 13, the number of required design sprinklers is the four most hydraulically demanding sprinklers. The minimum required dis- charge from each of the four sprinklers is the greater of the following: • flow rates listed in Table A or B as a function of temperature rating and the maximum allowable coverage area. • minimum discharge of 0.1 gpm/ft2 over the design area comprised of the four most hydraulically demanding sprin- klers for the actual coverage areas protected by four sprinklers. The number of "design sprinklers" specified in NFPA 13 for wet pipe sys- tems is to be applied when designing dry pipe systems. Dry Pipe System Water Delivery When using the Series LFII Residential Sprinklers (TY2235) in dry pipe sprin- kler systems, the time for water deliv- ery must not exceed 15 seconds for the most remote operating sprinkler. Obstruction to Water Distribution Sprinklers are to be located in accor- dance with the obstruction rules of NFPA 13D, 13R, and 13 as applicable for residential sprinklers as well as with the obstruction criteria described within the TYCO Technical Data Sheet TFP490. •' `• • :� M r• • Figure 2. Sprinkler Spacing The minimum spacing between sprin- klers is 8 feet (2,4 m). The maximum spacing between sprinklers cannot ex- ceed the length of the coverage area (Table A) being hydraulically calculated (e.g., a maximum of 12 feet for a 12 ft. x 12 ft. coverage area or 2(rfeef for a 20 ft. x 20 ft. coverage area.) Sprinkler Fittings The following fittings may be used: • The 1 inch NPT outlet or run of a mal- leable or ductile iron threaded tee fittings that meet the dimensional re- quirements of ANSI B16.3 (Class 150) • The 1 inch NPT outlet or run of a cast iron threaded tee fittings that meet the dimensional requirements of ANSI B16.4 (Class 125). For dry pipe systems, only use the side outlet of maximum 2-1/2 inch size reducing tees when locating the Series LFII Dry Type Residen- tial Recessed Pendent Sprinklers directly below the branch line. Oth- erwise, use the configuration shown in Figure 5 to assure complete drainage from above the Series LFII Sprinklers and the branch line. Do not install the Series LFII Dry Type Residential Recessed Pen- dent Sprinklers into elbow fittings. The Inlet of the sprinkler can con- tact the interior of the elbow, po- tentially damaging the Inlet seal. Only use the configuration in Fig- ure 4 where the sprinkler fitting and water -filled pipe above the sprinkler fitting are not subject to freezing and where the length of the Series LFII Sprinkler has the minimum exposure length per Figure 6. Refer to the Ex- posure Length section and 'Table C. • The 1 inch NPT outlet of a GRINNELL Figure 730 Mechanical Tee in wet pipe systems only • The 1 inch NPT CPVC outlet of a 1" x 1" x 1" NPT Sprinkler Head Adapter Tee (P/N 80249) in wet pipe systems only • The 1 inch NPT CPVC outlet of a 1" x 1" NPT Female Adapter (P/N 80145) in wet pipe systems only • The 1 inch NPT outlet of a 1" x 1" x 1" NPT CPVC Sprinkler Head Adapter Tee (P/N 80259) in either wet or dry pipe systems m Do not install the Series LFII Dry Type Residential Recessed Pendent Sprin- klers into any other type fitting without first consulting the Technical Services Department. Failure to use the appro- priate fitting may result in the following, • failure of the sprinkler to operate properly due to formation of ice over the Inlet Plug or binding of the Inlet Plug. • insufficient engagement of the in- let pipe threads with consequent leakage. Drainage Branch, cross, and feed -main piping connected to Series LFII Dry Type Res- idential Recessed Pendent Sprinklers and subject to freezing temperatures must be pitched to allow proper drain- age, in accordance with the minimum requirements of the National Fire Pro- tection Association for dry pipe sprin- kler systems. Exposure Length When using Series LFII Dry Type Resi- dential Recessed Pendent Sprinklers in wet pipe sprinkler systems to protect areas subject to freezing temperatures, use Table C to determine a sprinkler's appropriate exposed barrel length to prevent water from freezing in the con- necting pipes due to conduction. The exposed barrel length measurement must be taken from the face of the sprinkler fitting to the surface of the structure or insulation that is exposed to the heated area. Refer to Figure 6 for an example.

Due to tempera- ture differences between two areas, the potential for the formation of con- densation in the sprinkler and subse- quent ice build-up is increased. If this condensation is not controlled, ice build-up can occur that might damage the dry type sprinkler and/or prevent proper operation in a fire situation. Use of the Model DSB-2 Dry Sprin- kler Boot, described in Technical Data Sheet TFP591 and shown in Figures 4 through 6, can provide the recom- mended seal.

For other important require- ments regarding piping design and seating of the clearance space around the Sprinkler Casing, refer to the De- sign Criteria section. Do not install any bulb type sprinkler if the Bulb is cracked or there is a loss of liquid from the Bulb. With the sprin- kler held horizontally, a small air bubble should be present. The diameter of the air bubble is approximately 1/16 inch (1,6 mm). A leak -tight 1 inch NPT sprinkler joint should be obtained by applying a min- imum -to -maximum torque of 20 to 30 ft.-lbs. (26,8 to 40,2 Nm). Higher levels of torque can distort the sprinkler Inlet or Frame with consequent leakage or impairment of the sprinkler.

TABLE C MINIMUM RECOMMENDED LENGTHS OF EXPOSED SPRINKLER BARRELS IN WET PIPE SYSTEMS • The TYCO RAPID RESPONSE Series LFII Dry Type Residential Recessed Pendent Sprinklers (TY2235) must be maintained and serviced in accordance with this section: Before closing afire protection system main control valve for maintenance work on the fire protection system that it controls, obtain permission to shut down the affected fire protection sys- tems from the proper authorities and notify all personnel who may be af- fected by this action. Absence of a Recessed Escutch- eon Plate to cover a clearance hole can delay sprinkler operation in a fire situation. The owner must assure that the sprin- klers are not used for hanging any ob- jects and that the sprinklers are only cleaned by means of gently dusting with a feather duster; otherwise, non - operation in the event of a fire or inad- vertent operation may result. A Vent Hole is provided in the Bulb Seat (Figure 1) to indicate if the Series LFII Dry Type Residential Sprinkler is remaining dry. Evidence of leafage from the Vent Hole indicates poten- tial leakage past the Plug with Seal- ing Assembly and the need to remove the sprinkler to determine the cause of leakage (for example, an improper installation or an ice plug). Close the fire protection system control valve and drain the system before removing the sprinkler. Sprinklers which are found to be teak, ing or exhibiting visible signs of corro- sion must be replaced. Automatic sprinklers must never be painted, plated, coated, or other- wise altered after leaving the factory. Modified sprinklers must be replaced. Sprinklers that have been exposed to corrosive products of combustion, but have not operated, should be replaced if they cannot be completely cleaned by wiping the sprinkler with a cloth or by brushing it with a soft bristle brush. Care must be exercised to avoid dam- age to the sprinklers - before, during, and after installation. Sprinklers dam- aged by dropping, striking, wrench twist/slippage, or the like, must be replaced, Also, replace any sprinkler that has a cracked bulb or that has lost liquid from its bulb. (Ref. Installation Section.) The owner is responsible for the in- spection, testing, and maintenance of their fire protection system and devices in compliance with this document, as well as with the applicable standards of the National Fire Protection Asso- ciation (e.g., NFPA 25), in addition to the standards of any authorities hav- ing jurisdiction. Contact the installing contractor or sprinkler manufacturer regarding any questions. Automatic sprinkler systems are rec- ommended to be inspected, tested, and maintained by a qualified Inspec- tion Service in accordance with local requirements and/or national codes.

Escafato'Sr do not permit water discharge in elevator shafts until electrical power to the elevator cab has been shut down. This situation necessitates some special arrangement, such as a preactron systern, to make sure that water does riot flow in the elevator shaft until power shutdown has occurred. The additronal cost of a special installation and tire benefit-, returned for the protection inust be weighed against 9)e small number of fires in elevator shafts, Several papers on this topic were presented by participants, including the American Society of Mechanical Engtneeis {ASME}, ), at a symposium in F ebt nary 1991, in Baltimore, MD (Ptoceedings of the Syf nposiurn Carr Elevators and Fiat s). Subjects covered at this symposturn ranged front general elevator safety to potential problems associated with preirraluft, discharge of water onto elevator control elements Followifig this symposium, representatives fforil the building code organizations and ASME worked to resolve the problem of providing proper fire protection without sacirficing any of the inherent safety features of the sprinkler system or elevator and its associated equipment The result of this cooperation was the development of 8 to specifically address the installation Of Spirriklers in elevator shafts anti equipment rooms. This area is constantly changing, and sours changes have been proposed to ASME At 7.1 that uray result in modification of elevator requirements in the future. Also, in some jurisdictions, there is a movement to eliminate the sprinklers and automatic shutdown, so that the fire service can tontines to use the elevator as long as possible when fighting fires in a high-rise building Arty modificabons to these rules that would perfrtit the omission of sprinklers by local officials need to be carefully considered, due to the possibility of uncontrolled fire growth within elevator machine rooms combined with simultaneous fire department dependence on the elevators Additional concert) surrounds the fire department's assumption when responding to a fire incident within an elevator machine room that such spaces within the building are fully sprinklered. 117".Y7 * ibW . � I e it om or-eUiffffeievator noistway not more tha _6�11_111 m) above the floor of the pit. A.&15,5,1 The sprinklers in the pit are intended to protect against fires caused by debris, which can accunrulate, over time Ideally, the sprinklers should be located near the side of the pit below the elevator doors, where roost debris accuri rotates Howevet, care should be taken that the sprinkler location does not interfere with the elevator toe quard, which extends below the face of the door opening. ASAAE A 17 1 Safety Code for Flevatots and Escalators, allows the sprinklers within 2 It (0,65 in) of the bottom of the pit to be exempted from the special arrangements of indibiting waterflow until elevator recall ties occurred Refuse and reside al hydtauiic fluids tend to coliect at the bottorti of shafts. A property located sprinkler, as required by 8 1 -' �5 1 can control a fire of such material, Conventional requirements regarding the placernent of the deflector and clear space below the sprinkler cannot always be adhered to in this area. These issues are not critical, however, because the sprinkler would be physically close to any point where a fire could originate, still allowing the sprinkler to control the fire. Because the sprinkler at the pattern of the shaft cannot discharge onto the elevator or other operating components of the elevator, ASME A 17 1 no longer requires that the sprinkler discharge at the bottorn of the shaft be delayed until power struldown has occurred. "Tits Sp inkier at the bottoin of the shaft, where installed, is permitted to be part of the normal building sprinkler system and is not required to be part of the special system used to protect the, rest of the elevator equipment. 8.15.5.3* Automatic sprinklers in elevator machine rooms or at the tops of hoistways shall be of ordinary- or intermediate -temperature rating. A.B.15.5.3 ASME A17.1, Safety Code for Elevators and Escalators, requires the shutdown of power to the elevator upon or prior to the application of water in elevator machine rooms or horstways, This shutdown can be accomplished by a detection system with sufficient sensitivity that operates prior to the activation of the sprinklers (see also NFPA 72 ,r , National Fire Aintro and Signaling Code,) As an alternative, the system can be arranged using devices or sprinklers capable of effecting power shutdown immediately upon sprinkler activation, such as a waterflow switch without atrace delay This, alternative arrangement is intended to interrupt power before significant sprinkler Ee= 8,15,5A* Uptight, pendent, or sidewall spray sprinklers shall be installed at the top of elevator horstways Historically, upright oy pendent sprinklers were required at the top of the elevator shaft In many instances, however, irpright/perideot sprinklers cannot be centered above the hoistway because cables and so forth are present Sidewall sprinklers, which can be rn,*,talled clear of elevating equipment and nray be easier to install and replace, are now permitted as an alternative. A.8.15.5.4 Passenger elevator cars that have been constructed in accordance with ASME A17.1, Safety Code for Elevators and Escalators, Rule 204.2a (under Al 7.1 a-1 985 and later editions of the code) have limited combustibility. Materials exposed to the interior of the car and the hoistway, in their end -use composition, are limited to a flame spread index of 0 to 75 and a smoke developed index of 0 to 450, when tested in accordance with ASTM E 84, Standard Test Method of Surface Burning Characteristics of Building Materials. 8.115.5.6 The sprinkler required at the top of the elevator hoistway by 81 - 5 `5.4 shall not be required where the hoistway for passenger elevators is noncombustible or limited -combustible and the car enclosure materials meet the requirements of ASME Al 7. 1, Safety Code for Elevators and Escalators. 8.15.5.6 Sprinklers shall be installed at the top and bottom of elevator hoistways where elevators utilize polyurethane - coated steel belts or other similar combustible belt material. Likewise, these principles of Section 4_3 answer the question, are sprinklers required in large ceiling pockets [over 100 ft3 (2.83 m3) in volume]? Once again, the answer is yes, because 4_3(1) requires sprinklers in all spaces and 6.2.4.2 allows sprinklers to be omitted from pockets up to 100 ft' (2.83 m3); therefore, anything over 100 ft3 (2.83 m) requires sprinklers. 6.1 System Protection Area Limitations Section 6.1 establishes the maximum size of a sprinkler system on a single floor of a building as 52,000 ft2 (4831 m). Note that a single system with a single control valve would be permitted to protect a multiple -story building as long as no single floor was greater than 52,000 ft` (4831 m2) in area. The purpose of having a maximum area at all is to limit the amount of space that would be unprotected if a valve needed to be closed in order to perform maintenance or repair on a system. The reason that multiple floors are allowed to be protected with the same system without adding the area is that there is some natural fire resistance between floors of most buildings. The floor/ceiling assembly tends to help compartmentalize a building so that it is more difficult for the fire to head from floor to floor. Also, most codes require large buildings with many floors to have waterflow switches on each floor, which leads to separate control valves on each floor in many buildings, Therefore„ only a single floor tends to be out of service at any given time. 6,1.1 The maximum floor area on any one floor to be protected by sprinklers supplied by any one sprinkler system riser or combined system riser shall not exceed 52„000 ft2 (4831 m'), For buildings where any single floor is greater than 52,000 ft2 (4831 m2), multiple systems using multiple risers are required to be installed. The systems are not required to be separated in any way, but the multiple systems need to e installed so that the floor area that is not protected when a valve is closed is not greater than 52,000 fie (4831 m2). Where multiple risers are necessary to meet the system area limitations, a manifold riser arrangement can be considered. 6.2.1.3 Listed quick -response sprinklers shall be permitted to be installed in dwelling units meeting the definition of a compartment, as defined in Section 3.3, where no more than four sprinklers are located in the dwelling unit. The requirement in 66.2.13 permits the use of quick -response sprinklers in applications where the desired performance can be achieved without the wall -wetting characteristics associated with residential sprinklers. The requirement also permits systems to be installer) in instances where room layout or ceiling configuration can restrict the use of residential sprinklers (R 1 J. For example, a hotel room could be protected with quick -response extended coverage sidewall sprinklers„ which are not listed as residential sprinklers. An arrangement using quick - response sprinklers is considered to provide an acceptable level of protection for NFPA 13R systems. Exhibit 11.6.5 illustrates an example of the application of ,2.11.,.3. Paragraph 6.2.1.3 is frequently called the "hotel room exception" because the dwelling unit for which this paragraph is most often used is a hotel room. This paragraph was written for the first edition of NFPA 13R in order to help the lodging industry. During the 1980s, the lodging industry was making a concerted effort to sprinkler all of their hotels (both new construction and existing buildings) in the wake of disastrous fires in Las Vegas, Nevada, Mamaroneck, New York, and Puerto Rico. The most efficient way to sprinkler most hotel rooms is with a single sidewall sprinkler that can throw water spray 22 ft (6.7 m) into the room, which protects most of the bedroom area. Back when NFPA 13R was initially written, no residential sprinklers were listed with a 22 ft (6.7 m) throw. As a result, the committee worked out this compromise with the lodging industry. In these small dwelling units, quick -response sprinklers could be used, even though they were not tested or listed for providing tenable conditions in the room of fire origin. Part of the compromise was that the hotel room would also have a smoke detector for early warning. Although this detector requirement was originally included in the standard, it has been removed since all building codes require such a detector and NFPA 13R is a sprinkler standard, not a detector standard. Although 6.2.1.3 was written to apply to hotel guest rooms, it can apply to any dwelling unit that is similarly small, such as an efficiency apartment. Note that NFPA 13R requires the entire dwelling unit to be small enough to be protected with four sprinklers in order to apply 6.2.1.3. This requirement does not mean that each compartment needs only four sprinklers —it means that the whole dwelling unit, including all of the sleeping rooms, closets, bathrooms, foyers, and nooks, has to be small enough to be protected with four or fewer sprinklers. If quick -response sprinklers are used in accordance with 6.2.1.3, the system must be able to provide a minimum density of 0.1 gpm/ft2 (4.1 mm/min) over the design area, which is the entire dwelling unit in this case (using the "room design method" from NFPA 13, 11.2.3.3). Quick -response sprinklers are currently not evaluated for performance at lower densities such as 0.05 gpm/ft2 (2.04 mm/ruin). The minimum density requirement has also been added to 6.2.1.4, since quick -response sprinklers are permitted by that paragraph as well, The minimum density of 0.10 gpm/ft2 (4.1 mm/min) is consistent with the requirements for the use of quick -response sprinklers in NFPA 13. Previous editions of NFPA 13R permitted four standard -response sprinklers to be used. However, quick -response sprinklers provide a more effective means of achieving life safety than do standard -response sprinklers. This philosophy also holds true in NFPA 13, which now requires that listed quick -response or residential sprinklers be installed in light hazard occupancies. Additionally, when the exception for the standard -response sprinklers was first accepted in 1988, listed quick -response sprinklers were not as readily available as they are today. 6.2.1.3.1 Where quick -response sprinklers, including extended coverage quick -response sprinklers, are used, the density/area requirement shall be a minimum of 0.1 gpm/fl? (4.1 mm/min) over the entire dwelling unit. 6.2.1.3.2 Where extended coverage quick -response sprinklers are used, the flow shall be sufficient to meet the listing of the sprinklers at the spacing for which they are being used. 6.2.1.4 Quick -response sprinklers discharging a minimum of 0.1 gpmlfC (4.1 mm/min) shall be permitted to be used in mechanical closets. in certain mechanical closets, intermediate or high temperature sprinklers might be desirable due to the ambient temperatures in the space. At one time, residential sprinklers were not available in intermediate or high temperature ranges. Paragraph 62.1,.4 ' was added to NFPA 13R as a means to provide protection for these mechanical spaces where no residential sprinkler was available. Now, intermediate temperature rated residential sprinklers are available, but this requirement remains in the standard because the life safety aspects of residential sprinklers are not needed in a mechanical closet. 6.2.2.2 Residential sprinklers shall be permitted to be used in corridors leading to dwelling units and in areas covered by q�.47, Z,2,2, and 7.3.3. Residential sprinklers are appropriate for use where the fire threat is similar to that expected in a dwelling unit. The fuel loading in a corridor adjoining the dwelling units is typically substantially lower than that found in the dwelling units. In addition to the corridors leading to dwelling units, NFPA 13R permits residential sprinklers to be used in the following locations (see 6.4.7 and 77.3.3 J Lobbies (not in hotels and motels) with flat, smooth ceilings 0 2. Foyers with flat, smooth ceilings Corridors with flat, smooth ceilings Halls with flat, smooth ceilings Lounges with flat, smooth ceilings �_.J Other areas with fire loads similar to residential and having flat, smooth ceilings 0 7. Garages where entry Vnthe garage isonly available from osingle dwelling unit The criteria for aflat, smooth ceiling are consistent with the listing limitations ofresidential sprinklers [B@1�881� However, the user should note that this does not require the ceiling to be horizontal. A flat ceiling is one that exists in a single plane, but that plane is permitted to be sloped, As long as a sloped ceiling does not have any irregular bumps or indentations, it is considered flat and smooth because it exists in a single plane. Residential sprinklers used under a sloped ceiling need to be listed for the slope. If no residential sprinklers are listed for the slope, then residential sprinklers cannot be used in this circumstance and quick -response sprinklers should be used, taking into account the 3Opercent increase 0uthe design area due hothe slope. A.6.2.3.1 Sprinklers having atemperature rating of135^Fto17O^F(57^Cho77^C)are classified exordinary temperature —rated sprinklers, NFPA 13R requires a difference of at least 35'F (19'C) between the highest expected ambient temperature and the sprinkler activating temperature as a safety factor. If the ambient temperature is expected to be no more than 1 00'F (380C), the sprinkler is permitted to have an activation temperature of 135'F (57*C). However, in reality, the safety factor ishigher since sprinklers with activating temperatures of 135'F (57^C) are very rare. Ordinary temperature sprinklers are more typically 155"For1G5"F(88Tor74~C). The reason that NFPA 13R prefers the use of ordinary temperature sprinklers is to make sure that the sprinkler will activate early in the fire scenario. If sprinklers are installed with temperature ratings that are too high, itwill take longer for the sprinkler to achieve its operating temperature. The only times that intermediate or high temperature sprinklers should be used is where the ambient temperature will be greater than 1 00'F (38'C) or where sprinklers are close toolocal heat source such as astove orediffuser from oheating duct. See �2.3.3for more information nn local heat sources. 6.2.3.3.2 Sprinklers in an unventilated concealed space under uninsulated roof or in an unventilated attic shall be of intermediate temperature dauaifiuotion. NFPA 13R does not require sprinklers in most attics. However, if sprinklers are installed in an unventilated attic, they need to have the correct temperature rating. Unventilated attics tend to develop rather high temperatures in the summer months. Thus, precautions to prevent false activation in unventilated attics should be undertaken. Selecting the appropriate temperature rating for a given environment is always important. The correct temperature rating helps to ensure that sprinklers will not operate prematurely and that an excessive number of sprinklers will not operate during the fire. Sprinklers installed in the vicinity of heat -producing equipment such as fireplaces or wood -burning stoves need to be rated for higher temperatures because the sprinklers can be exposed to relatively high temperatures. The requirements of 6.2.3.3, as well as the manufacturer's instructions, must be followed with regard to sprinkler temperature classification and placement where high ambient temperatures are expected. Positioning sprinklers closer to heat -producing equipment than permitted by Table 6.2.3.3.3iolikely toresult infalse activation of the sprinkler. Paragraph 6.2.3.3.3 permits closer distances than indicated in Table 6.2.3.3.3.vvhena sprinklers are specifically listed for such distance. Examples of high temperature locations include wood -burning stoves, fireplaces, and hot air diffusers, eushown inExhibit UJ6.O. 6.2.3.5 Sprinkler Positioning. 6.2.3.5.1 Sprinklers shall bepositioned uothat the response time and discharge are not unduly affected by obstructions such aoceiling slope, beams, orlight fixtures. 8.2.3.5.2Small areas created byarchitectural features such aoplanter box windows, bay windows, and similar features shall be evaluated as follows: Where no additional floor area iscreated bythe architectural feature, noadditional sprinkler protection isrequired. Where additional floor area is created by an architectural feature, no additional sprinkler protection is required, provided all of the following conditions are met: o (a) The floor area shall not exceed 18 ft2 (1.7 m2). o (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. o (c) The floor shall not be greater than 9 ft (2.7 m) in length where measured along the plane of the primary wall. 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. ra rlu 6.4 Residential Sprinklers 0 6.4.1 Residential Sprinklers That Have Been Listed with Specific Coverage Criteria. Sprinklers shall be installed in accordance with the coverage criteria specified by the listing. Residential sprinklers are different from other types of sprinklers in that much of the installation criteria and discharge criteria are found in the listing of the sprinkler, not in NFPA 13R. Issues such as maximum allowable distances between sprinklers (spacing criteria) and maximum allowable distances to walls are determined by the manufacturer and verified by a listing laboratory. In addition, these distances are tied specifically to certain discharge criteria that are also determined by the manufacturer and verified by the listing laboratory. As a consequence of the spacing criteria being linked to the discharge criteria and the manufacturer having the ability to make their own determinations about what those numbers can be, residential sprinklers are not interchangeable. One residential sprinkler might be listed to cover a 16 ft x 16 It (4.9 m x 4.9 m) area at a flow rate of 13 gpm (49 Umin) and a pressure of 7 psi (0.5 bar), and a second residential sprinkler might be listed to cover the same area of 16 ft x 16 ft (4.9 m x 4.9 m) with a flow rate of 18 gpm (68 Umin) at a pressure of 10.3 psi (0.7 bar). In this case, if the first sprinkler was originally planned for a project and used in the design of the system, and the hydraulic calculations showed that it worked, the second sprinkler could not be substituted for the first without additional calculations to show that it would work. Even though the second sprinkler is listed for the same area of coverage, it would not necessarily work with the water supply of the first sprinkler because it has a greater flow rate and pressure demand. At one time some residential sprinklers were listed without any specific flow and pressure requirements. These sprinklers were permitted to protect 12 ft x 12 ft (3.6 m x 3.6 m) spaces at a flow rate of 18 gpm (68 LJmin) from the first sprinkler and 13 gpm (49 Umin) when multiple sprinklers were being calculated, However, none of these sprinklers are currently being manufactured due to their relative inefficiencies. In most residential occupancies, sprinklers are needed that can cover more than 144 ft2 (13.4 m 2 ) at a time in order to minimize the number of sprinklers that need to be installed. 6.4.5 Operating Pressure. The minimum operating pressure of any sprinkler shall be the higher of the minimum operating pressure specified by the listing or 7 psi (0,5 bar). There are two reasons for the minimum operating pressure of 7 psi (0.5 bar). The first is that the water needs to leave the sprinkler with sufficient energy to spread out over its coverage area. At pressures less than 7 psi (0.5 bar), the sprinkler's spray pattern might not reach the entire coverage area necessary and might leave significant dry spots where a fire might continue to burn, uncontrolled. The listing laboratories evaluate the spray pattern of the sprinkler at 7 psi (0.5 bar) to make sure that it is acceptable. The second reason that the 7 psi (0.5 bar) minimum is important is that the cap holding the sprinkler closed needs some force behind it to throw it aside when the sprinkler operates so that the water can flow. The water pressure provides this force to clear the cap. Even though the listing laboratories run the test at a lower pressure [typically 3 psi (0.2 bar)], a safety factor needs to be applied to account for field conditions that may cause the cap to stick to the sprinkler. 6.4.6 Position of Residential Sprinklers. 6.4.6.1 Pendent and Upright Sprinklers. 6.4.6.1.1 Pendent and upright sprinklers that have not been listed with specific positioning criteria shall be positioned so that the deflectors are within 1 in. to 4 in. (25.4 mm to 102 mm) from the ceiling. 6.4.6.1.2 Pendent and upright sprinklers that have been listed with specific positioning criteria shall be positioned in accordance with the listing. 6.4.6.1.3 Pendent and upright sprinklers shall be located a minimum of 4 in. (102 mm) from a wall. The reason pendent and upright sprinklers need to be at least 4 in. (102 mm) from a wall is commonly thought to be due to the operating characteristics of the sprinklers. Within this area, a dead air space near the wall delays sprinkler activations. The actual reason behind the minimum 4 in, (102 mm) rule is a practical matter of installation. Sprinklers need to be installed with special sprinkler wrenches that surround the sprinkler and put the correct amount of torque on the body of the sprinkler without causing stress to the frame, deflector, or operating mechanism. These special wrenches need room to be used properly. A sprinkler too close to the wall will be impossible to install with the correct wrench and will need to be installed by some other method, which might risk stress to the important parts of the sprinkler leading to potential leakage, accidental discharge, or other problems. 6.4.6.2 Sidewall Sprinklers. 6.4.6.2.1 Sidewall sprinklers that have not been listed with specific positioning criteria shall be positioned so that the deflectors are within 4 in. to 6 in. (102 mm to 152 mm) from the ceiling. 6.4.6.2.2 Sidewall sprinklers that have been listed with specific positioning criteria shall be positioned in accordance with the listing. 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. (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: o (a) The floor area does not exceed 18 f:2 (1.7 mz). 0 (b) The floor area is not greater than 2ft(O.O1n)indepth atthe deepest point nfthe architectural feature tothe plane of the primary wall where measured along the finished floor. The floor is not greater than 9 ft (2.7 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 ofthe sprinkler. The hydraulic design is not required 0oconsider the area created bythe architectural feature. 6.4.6.3.3 SidewaUSphnNen* 6.4.6.3.3.1 Sidewall sprinklers shall be located at least 5 ft (1.52 m) from obstructions such as ceiling fans and light fixtures unless the requirements of 6.4.6.3,5 are met. 6.4.6.3.3.2 The distance shall be measured from the center of the sprinkler to the centerofthe obstruction. Residential occupancies undergosignificant changes during constructionEven ifasprinkler contractor knows what sort of light fixtures and ceiling fans are going to be installed when they are brought in at the beginning of a project, there is no guarantee that these are the fixtures that are going to be installed at the end of the project, Therefore, rather requirethan the distance from the sprinkler to the obstruction to be measured to the edge of the obstruction (as it is in NFPA 13), NFPA 13R only requires the distance to be measured to the center of the obstruction. In this manner, the sprinkler can always be installed without knowing exactly which fixture will be installed or exactly how large it will be. The sprinkler installer knows where the fixtures will go (generally the center of the room) and has visual cues from the electrician, who will usually install an electric box even if no fixture is intended for installation at the time. The technical committee took this concept into account when considering the minimum 5 ft (1.5 m) rule. 6.4.6.3.3.3VVher the sprinkler cannot be located 5 ft (1.52 m) from the obstruction (as measured to the centerof the obstruction), an additional sprinkler shall be installed on the other side of the obstruction. 6.4.6.3.6Soffits and Cabinets. Where soffits are used for the installation of sidewall sprinklers, the sprinklers and soffits shall beinstalled inaccordance with 6�'.63,8L1.84}��.or6.4-,6,3.,6`3. Soffits and cabinets are special continuous obstructions. These special obstructions U less ofaconcern than other continuous obstructions because they are generally installed onwalls. |fafire does start under asoffit or cabinet, places are limited for the fire todevelop and spread because the wall prevents the fire from moving any more inthat direction and the sprinklers will still open and keep the fire from gettingout from under the soffit orcabinet. The first ufthe rules dealing withsoffits iolocated in6i*.6,l4 ',3. This rule al lows pendent sprinklers som e �omnthe «�heroon�nuousskm��imnrules based mnthe themrythat the wall will help control the spread offire. Note the 8in, (02 m)dis\amoe inthe formula given inFigure G/4'6'3,4,3that helps position the pendent sprinkler. This distance of 8 in. (0,2 m) is the same distance found in 6.4,63.61 for sidewall sprinklers. When protecting a space with soffits and/or cabinets, the best option for getting water spray under the cabinets is a pendent sprinkler in the compartment 'naccordance with 6AG3 4'3, The second best option is tmuse asidewa||sprinkler mnthe wall mnthe other side ofthe room from the soffit orcabinet and spraying toward the wmffi(orcabinet. The third best option iw10 put the sprinkler unthe same wall as the soffit or cabinet. In this case, the sprinkler needs to be flush with the face of the cabinet to avoid obstructions caused by objects that might be placed on the top of the cabinet, or the sprinkler needs hobn3ft(U.Dm)above the top ofthe cabinet hobeable huspray over it.

Tim is out on extended leave and I have not been able to address all the issues you have brought up. I again extend my apologies for how this was handled.

I've been thinking about this often and how wrong this whole situation is on several levels. Essentially what Tim did is hold the job hostage unless we bonded the sprinkler pipe the way he wanted, which is not what we discussed. Tim told my electrician that he would approve the service before he left the job site if they removed the sprinkler bonding as installed and bond it to the sprinkler riser pipe, only then would he give us "service". Tim's actions not only cost us time and money but in my opinion were way out of line and has now confused several electricians including myself on NEC 250.104A, which clearly states the connection need only be accessible. I have discussed this issue with several industry people and each one interpret NEC 250.104A the same as I do, so with that said I would appreciate an explanation from Tim on how our original installation was wrong and what code section it would have violated. Also in your voice message you said you were checking with Tumwater because something was not exactly clear or done properly. I'm not sure what that was, maybe you can clarify that since I already deleted your message. Has Tumwater come back with anything yet? Please advise, I need to make sure my team knows what to do on the next project. 0 From: Bruno Padilla Sent: Thursday, October O3,2O1]3:32RM To: "Vance,Jerry ] (LNI)' Subject: FVV: Best Western sprinkler hserasgnoundingalectnode I tried to have a discussion with Tim yesterday, but he wasn't willing to listen to anything I had to say. fact he was quite rude during our conversation, which I thought was completely out of line and very unprofessional. In all my years as a Contractor I have never been treated like this before when trying t discuss code issues with an Inspector. The phone call ended with him telling me (in a raised voice) that he wasn't going to argue with me and to "just run the #$@ wire" then hung up. I think it is important you to know how your inspectors handle themselves, I know I would want to know if my electricians a rude to my customers. This was such an outrageous experience with Tim that I am concerned about Bels Western project. I With that said, I am in limbo with this correction that we discussed a couple days ago so I consulted with the Arlington Fire Department Deputy Chief to see what their requirements are. You can see his response below. I passed on Tim's and your phone numbers so you guys can work it out. At this point the project is being impacted because the elevator contractor will not start until permanent power is available. We have a "wall cover" inspection called in for Friday, Is it possible to get "service approval" since that was the only correction while this issue is being worked out? We have an approved Ufer ground so it's not like we are without a grounding electrode. This will help minimize the impacts to the contractor. Please call if you have any questions or want to discuss.

Tom Cooper 91 Deputy Chief Arlington Fire Department 360-403-3607 tcooper@arlingtonwa.gov National Fire code- subscription service - Home, ge Page 10 of 25 A.10.6.7 Gray cast iron is not considered galvanically dissimilar to ductile iron. Rubber gasket joints (unrestrained push -on or mechanical joints) are not considered connected electrically. Metal thickness should not be considered a protection against corrosive environments. In the case of cast iron or ductile iron pipe for soil evaluation and external protection systems, see Appendix A of AWWA C105, Polyethylene Encasement for Ductile Iron Pipe Systems. [24: A.10.6.7] In no case shall the underground piping be used as a grounding electrode for electrical systems. [24:10.6.8] FAQ Why does the requirement ofl".,_Q prohibit the use of underground piping for grounding of electrical services? The use of underground fire, protection piping for electrical grounding increases the potential for stray ground currents and increased galvanic corrosion, which is why such use is prohibited by 111.6-8. Grounding to piping systems that could have nonrooduetive piping or joints Is especially dangefous, since it may not provide the expected ground. In no case should the underground piping be used as a grounding electrode for electrical systems. Electrical equipment should be grounded in accordance with yf)!A 7Qs, National Electrical Code's. A.10.6.8 Where lightning protection is provided for a structure, t1EP'A78% 4.14 requires that all grounding media, including underground metallic piping systems, be interconnected to provide common ground potential. These underground piping systems are not permitted to be substituted for grounding Oectrodes but must be bonded to the lightning protection grounding systern. Where galvanic corrosion is of concern, this bond can be made via a spark gap or gas discharge tube. [24: A.10.6.8] AH3 FAQ How can it be determined that the underground service is being used as a grounding electrode? ANSWER: if there is a large diameter copper cable running from the electrical service panel that is attached to the sprinkler system's service main as it enters the building, it is a telltale sign that the underground service 15 being used as a grounding electrode. If a larger diameter copper cable is attached to the fire service main as it enters the building, the electrical inspector will need to examine it to make sure the sprinkler system's service main is not being used as a grounding electrode. Ii10,6.8.1* The requirement of 1%6.6 shall not preclude the bonding of the underground piping to the lightning protection Vgrounding system as required by Nti 6 74,0 in those cases where lightning protection Is provided for the structure, [24.10.6.8.1] A.10.6.8.1 While the use of the underground fire protection piping as the grounding electrode for the building Is prohibited, 8LFE4..70 requires that all metallic piping systems be bonded and grounded to disperse stray electrical currents. Therefore, the fire protection piping will be bonded to other metallic systems and grounded, but the electrical system will need an additional ground for its operation. RW_ WA The precautions that must be taken to minimize damage to underground piping, eliminate stresses, and ensure a long service life are outlined in Section 10.7. In the United States, the federal Occupational Safety and Health Administration (OSHA) has a number of requirements relating to safety issues involved in underground piping installation. These OSHA regulations can be found in standards 29 CFR 1926, Subpart P, on excavations and 29 CFR 1910.146 on confined spaces. For trenching operations, sloping, shoring, or shielding of the trench might be required. Soil classification is needed to select the correct options. In the absence of soil classification, sloping of the excavation wall can be performed with the slope limited to Iifa horizontal to I vertical, which is a maximum of 34 degrees from horizontal. Confined space entry procedures are often triggered when access K needed to control valves located In pits. For this reason, control valves are brought above ground in areas where freezing is not a concern, and special prefabricated heated enclosures (see Exhibit lfli are available to allow aboveground valve installations in areas subject to freezing.
