Main residence shows UG length as 140' on plans and 130' in calculations. Increase friction loss adds 0.25 psi to demand pressure, increasing required to 48.95 psi. 90% of available pressure is 63 psi. No revision required. Guest residence shows UG length as 130' on plans and 120' in calculations. Increase friction loss adds 0.28 psi to demand pressure, increasing required to 61.58 psi. 90% of available pressure is 63 psi. No revision required. 2. A test connection should be provided for each building, and was not found on the plans. This can be field verified. The following comments are for your information and will appear on every residential sprinkler review. The alarm bell must be capable of being heard, above background noise, with doors closed, in all living areas of the residence. This will be checked at final acceptance. Pressure required at base of riser will be verified to be available at time of final acceptance. Sprinkler heads are omitted from bathroom areas under 55 SF in area with noncombustible plumbing fixtures. Fixtures will be verified at final acceptance. Sprinkler head blockage or pattern disruption caused by beams or other obstructions will be verified to not exist at final acceptance inspection. Sprinkler heads should be located the proper distance from heat sources (stoves, kitchen ranges, fireplaces, heat diffusers, etc.) This will be checked at final acceptance inspection. Sprinkler heads located in an unconditioned space (garage, water heater closet, etc.) should be fast response type with an appropriate temperature rating, commercial heads are acceptable in these areas. All exposed piping shall be black steel or copper. Concealed piping can be CPVC plastic. ihese plans has hera reviesi ed tor afipilent coiphan.e with hr curiew applicable codes and mandards in hirce I UtidiLtilil FIlL tinet lii' collilactil lllaV utili,e ii as ase ii s)p)rt ot an ippIicttin or a huitiliti iii is tb the e press uriderhinditig Illat this ret leo it ii rljess the owner or cilitractor or their phssiiitl dig tear or aiLIlitLdt torsole respntsthiIit tol till artipliatice with said iacls and standards. ilL din the hVildill,it code or thr any responsihiliv for telietendias errors, olnislolts or ndfltiiisiicd in these olarls si taller ii not noted in lhis review. 1(3 Reviewer: Rld )NI bIlNf) APPRo )VA l RfC( )bi Ni NNI) APPR( )VAI AS NOTFI) iofl1' 5 -, SYMONS FIRE PROTECTION, INC. 1050 PIONEER WAY, SUITE R EL CAJON, CA 92020 LICENSE C16-682025 HYDRAULIC CALCULATIONS FOR LIN MAIN HOUSE REMOTE AREA 2 HEAD CALC TYCO LF II CONC/FLAT FILE NUMBER: 13-259 DATE: 12-13-13 -DESIGN DATA- OCCUPANCY CLASSIFICATION: R3 .05 gpm/256 sq. ft. 512 sq. ft. 2 sprinklers 26.0 gpm 31.0 gpm (5 gpm Hose STREAM) 26.0 gpm @ 25.0 Psi 4.9 CANDI CAUDILLO CARLSBAD FIRE DEPT. 70 Psi (-10% 63PSI) 69 Psi 500 gpm CARLSBAD WATER 8-1-13 DENSITY: AREA OF APPLICATION: NUMBER OF SPRINKLERS CALCULATED: TOTAL SPRINKLER WATER FLOW REQUIRED: TOTAL WATER REQUIRED (including hose) FLOW AND PRESSURE (@ NODE 5 BOR) SPRINKLER K-FACTOR (ORIFICE SIZE) DESIGN/LAYOUT BY: AUTHORITY HAVING JURISDICTION: WATER FLOW AVAILABILITY DATA: STATIC: RESIDUAL: FLOW: WATER DEPARTMENT: CALCULATIONS BY HASS COMPUTER PROGRAM HRS SYSTEMS, INC.

The cover plate assembly conceals the sprinkler operating components above the ceiling. The flat profile of the cover plate provides the optimum aes- thetically appealing sprinkler design. In addition, the concealed design of the Series LFII Residential Concealed Pendent Sprinklers (1Y3596) provides 1/2 inch (12,7 mm) vertical adjustment. This adjustment provides a measure of flexibility when cutting fixed 'sprinkler' drops." The Series LFII Residential Concealed Sprinklers are intended, for use in, the following scenarios: 'wet and dry pipe residential sprin- kler systems for one- and two-fam- ily dwellings and mobile homes per NFPA 13D wet and dry pipe residential sprin- kler systems for residential occu- pancies up to and including four stories in height per NFPA 13R wet and dry pipe sprinkler systems for the residential portions of any occupancy per NFPA 13 The Series LFII Residential Concealed Pendent Sprinklers (TY3596) has been designed with heat sensitivity and wa- ter distribution characteristics proven to help in the control of residential fires and to improve the chance for occu- pants to escape or be evacuated. The Series LFII Residential Concealed Pendent Sprinklers (1Y3596) are shipped with a Disposable Protective Cap. The Protective Cap is temporar- ily removed for installation, and then it can be replaced to help protect the sprinkler while the ceiling is being in- stalled or finished. The tip of the Pro- tective Cap can also be used to mark the center of the ceiling hole into plas- ter board, ceiling tiles, etc. by gently pushing the ceiling product against the Protective Cap. When the ceiling installation is complete the Protective Cap is removed and the Cover Plate Assembly installed. Dry Pipe System Application The Series LFII Residential Concealed Pendent Sprinklers offers a laboratory approved option for designing dry pipe residential sprinkler systems, whereas, most residential sprinklers are labora- tory approved for wet systems only. Through extensive testing, it has been determined that the number of design sprinklers (hydraulic design area) for the Series LFII Residential Concealed Pendent Sprinklers (TY3596) need not be increased over the number of de- sign sprinklers (hydraulic design area) as specified for wet pipe sprinkler sys- tems, as is accustomed for density/ area sprinkler systems designed per NFPA 13. The Series LFII Residential Con- cealed Pendent Sprinklers (TY3596) described herein must be installed and maintained in compliance with this document and with the applica- ble standards of the National Fire Pro- tection Association, in addition to the standards of any authorities having ju- risdiction. 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 installing contractor or sprinkler manufacturer should be contacted with any questions. Sprinkler Identification Number TY3596 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 in- stallation can permanently damage a sprinkler system or its components and cause the sprinkler to fail to operate in a fire situation or cause it to operate prematurely. Consequently, the Series LFII Residen- tial Concealed Pendent Sprinklers of- fer the features of non-water filled pipe in addition to not having to increase the number of design sprinklers (hy- draulic design area) for systems de- signed to NFPA 13, 13D, or 13R. Non- water filled pipe will permit options for areas sensitive to freezing.

At this point the De- flector supported by the Arms drops down to its operated position. The fus- ible link of the Sprinkler Assembly is comprised of two link halves that are soldered together with a thin layer of solder. When the rated temperature is reached, the solder melts and the two link halves separate allowing the sprin- kler to activate and flow water. Design Criteria The TYCO RAPID RESPONSE Series LFII Residential Concealed Pendent Sprinklers (TY3596) are UL and C-UL Listed for installation in accordance with this section. Note: When conditions exist that are outside the scope of the provided cri- teria, refer to the Residential Sprinkler Design Guide TFP490 for the manu- facturers recommendations that may be acceptable to the authority having jurisdiction. System Types Per the UL Listing, wet pipe and dry pipe systems may be utilized. Per the C-UL Listing, only wet pipe systems may be utilized. Refer to Technical Data Sheet TFP485 about the use of residential sprinklers in residential dry pipe systems. Ceiling Types Smooth flat horizontal, or beamed, or sloped, in accordance with the 2013 Edition of NFPA 13D, 13R, or 13 as applicable. Hydraulic Design (NFPA 13D and 13R) For systems designed to NFPA 13D or NFPA 13R, the minimum required sprinkler flow rates are given in Ta- bles A and B as a function of tem- perature rating and the maximum allowable coverage areas. The sprin- kler flow rate is the minimum re- quired 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 applied when designing dry pipe systems. Hydraulic Design (NFPA 13) For systems designed to NFPA 13, the number of design sprinklers is to be the four most hydraulically demanding sprinklers. The minimum required dis- charge from each of the four sprinklers is to be the greater of the following: The flow rates given in Tables A and B as a function of temperature rating and the maximum allowable coverage area. A minimum discharge of 0.1 gpm/ ft' over the "design area" comprised of the four most hydraulically demanding sprinklers for actual coverage areas protected by the 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 Residen- tial Concealed Pendent Sprinklers (1Y3596) in dry pipe sprinkler systems, the time for water delivery must not ex- ceed 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 with- in the Technical Data Sheet TFP490. Operational Sensitivity. The sprin- klers are to be installed relative to the ceiling mounting surface as shown in Figure 3. Sprinkler Spacing. The minimum spacing between sprinklers is 8 feet (2,4 m). The maximum spacing be- tween sprinklers cannot exceed the length of the coverage area (Ref. Table A or B) being hydraulically calculated (e.g., maximum 12 feet for a 12 ft. x 12 ft. coverage area, or 20 feet for a 20 ft. x 20 ft. coverage area). The Series LFII must not be used in applications where the air pressure above the ceiling is greater than that below. Down drafts through the Sup- port Cup could delay sprinkler opera- tion in a fire situation. The TYCO RAPID RESPONSE Series LFII Residential Concealed Pendent Sprinklers are only listed with the Se- ries LFII Concealed Cover Plates hav- ing a factory applied finish.

General Instructions Damage to the fusibld Link Assembly during installation can be avoided by handling the sprinkler by the support cup only (i.e., do not apply pressure to the fusible Link Assembly). A 1/2 inch NPT sprinkler joint should be obtained with a minimum to maxi- mum torque of 7 to 14 ft-lbs. (9,5 to 19,0 Nm). Higher levels of torque may distort the sprinkler inlet with conse- quent leakage or impairment of the sprinkler. Do not attempt to compensate for in- sufficient adjustment in the Cover Plate/Retainer Assembly by under-or over-tightening the Sprinkler. Readjust the position of the sprinkler fitting to suit. Step 1 The sprinkler must only be in- stalled in the pendent position and with the centerline of the sprinkler per- pendicular to the mounting surface. Step 2. Remove the Protective Cap. Step 3. With pipe thread sealant ap- plied to the pipe threads, and using the W-Type 18 Wrench shown in Figure 2, install and tighten the Sprinkler/Sup- port Cup Assembly into the fitting. The W-Type 18 Wrench will accept a 1/2 inch ratchet drive. Step 4. Replace the Protective Cap by pushing it upwards until it bottoms out against the Support Cup. The Protec- tive Cap helps prevent damage to the Deflector and Guide Pins during ceil- ing installation and/or during applica- tion of the finish coating of the ceil- ing. It may also be used to locate the center of the clearance hole by gen- tly pushing the ceiling material against the center point of the Cap. Note: As long as the protective Cap remains in place, the system is consid- ered to be "Out Of Service". Step 5. After the ceiling has been completed with the 2-1/2 inch (63 mm) diameter clearance hole and in prep- aration for installing the Cover Plate Assembly, remove and discard the Protective Cap, and verify that the De- flector moves up and down freely. If the Sprinkler has been damaged and the Deflector does not move up and down freely, replace the entire Sprin- kler assembly. Do not attempt to modi- fy or repair a damaged sprinkler. Step 6. Screw on the Cover Plate As- sembly until its flange comes in con- tact with the ceiling. Do not continue to screw on the Cover Plate Assembly such that it lifts a ceil- ing panel out of its normal position. If the Cover Plate Assembly cannot be engaged with the Mounting Cup or the Cover Plate Assembly cannot be engaged sufficiently to contact the ceiling, the Sprinkler Fitting must be repositioned. Care and Maintenance The TYCO RAPID RESPONSE Se- ries LFII Residential Concealed Pen- dent Sprinklers (TY3596) must be maintained and serviced in accordance with this section. Before closing a fire protection system main control valve for maintenance work on the fire protection system which it controls, permission to shut down the affected fire protection sys- tem must be obtained from the prop- er authorities and all personnel who may be affected by this action must be notified. Absence of a Cover Plate may de- lay the sprinkler operation in a fire situation. When properly installed, there is a nominal 1/8 inch (3,2 mm) air gap be- tween the lip of the Cover Plate and the ceiling, as shown in Figure 3. This air gap is necessary for proper op- eration of the sprinkler by allowing heat flow from a fire to pass below and above the Cover Plate to help as- sure appropriate release of the Cover Plate in a fire situation. If the ceiling is to be repainted after the installation of the Sprinkler, care must be exercised to ensure that the new paint does not seal off any of the air gap. Factory painted Cover Plates must not be repainted. They should be re- placed, if necessary, by factory paint- ed units. Non-factory applied paint may adversely delay or prevent sprin- kler operation in the event of a fire. Do not pull the Cover Plate relative to the Enclosure. Separation 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 otherwise altered after leaving the factory. Modi- fied or over heated sprinklers must be replaced. Care must be exercised to avoid dam- age -before, during, and after installa- tion. Sprinklers damaged by dropping, striking, wrench twist/slippage, or the like, must be replaced. The owner is responsible for the in- spection, testing, and maintenance of their fire protection system and devic- es in compliance with this document, as well as with the applicable stan- dards of the National Fire Protection Association (e.g., NFPA 25), in addition to the standards of any other authori- ties having jurisdiction. The installing contractor or sprinkler manufacturer should be contacted relative to any questions. 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. Automatic sprinkler systems should be inspected, tested, and maintained by a qualified Inspection Service in accor- dance with local requirements and/or national codes.

When aesthetics and optimized flow charac- teristics are the major consideration, the Series LFII Residential Sprinklers (1Y2234) should be the first choice. The Series LFII Residential Sprinklers are intended for use in the following scenarios: wet and dry pipe residential sprin- kler systems for one- and two-family dwellings and mobile homes per NFPA 13D wet and dry pipe residential sprinkler systems for residential occupancies up to and including four stories in height per NFPA 13R wet and dry pipe sprinkler systems for the residential portions of any occupancy per NFPA 13 The recessed version of the Series LFII Residential Sprinklers is intended for use in areas with finished ceilings. It employs a two-piece Style 20 Recessed Escutcheon. The Recessed Escutcheon provides 1/4 inch (6,4 mm) of recessed adjustment or up to 1/2 inch (12,7 mm) of total adjustment from the flush ceiling position. The adjustment provided by the Recessed 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 components. Improper handling and installation can permanently damage -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. Page 1 of 6 Escutcheon reduces the accuracy to which the pipe drops to the sprinklers must be cut. The Series LFII Residential Sprinklers have been designed with heat sensi- tivity and water distribution charac- teristics proven to help in the control of residential fires and to improve the chance for occupants to escape or be evacuated. Dry Pipe System Application The Series LFII Residential Pendent and Recessed Pendent Sprinklers offers 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, it has been determined that the number of design sprinklers (hydraulic design area) for the Series LEll Residential Pendent and Recessed Pendent Sprinklers (TY2234) need not be increased over the number of design sprinklers (hydraulic design area) as specified for wet pipe sprinkler systems, as is accustomed for density/ area sprinkler systems designed per NFPA 13. Consequently, the Series LFII Residential Sprinklers offer the features of non-water filled pipe in addition to not having to increase the number of design 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. ,NOTICE The Series LFIl Residential Pendent and Recessed Pendent Sprinklers (TY2234) 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 standards of any authorities having jurisdiction. Failure to do so may impair the perfor- mance of these devices. APRIL 2013 The owner is responsible for main- taining their fire protection system and devices in proper operating condition. The installing contractor or sprinkler manufacturer should be contacted with any questions.

Design Criteria The TYCO RAPID RESPONSE Series LFII Residential Pendent and Recessed Pendent Sprinklers (TY2234) are UL and C-UL Listed for installation in accordance with this section. Residential Sprinkler Design Guide When conditions exist that are outside the scope of the provided criteria, refer to the Residential Sprinkler Design Guide TFP490 for the manufacturer's recommendations that may be acceptable to the local authority having jurisdiction. System Types Per the UL Listing, wet pipe and dry pipe systems may be utilized. Per the C-UL Listing, only wet pipe systems may be utilized. Refer to Technical Data Sheet TFP485 for the use of residential sprinklers in residential dry pipe systems. Ceiling Types Smooth flat horizontal, or beamed, or sloped, in accordance with the 2013 Edition of NFPA 13D, 13R, or 13 as applicable. Hydraulic Design (NFPA 13D and 13R) For systems designed to NFPA 13D or NFPA 13R, the minimum required sprinkler flow rates are given in Tables A and B as a func- tion of temperature rating and the maximum allowable coverage 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 applied when designing dry pipe systems. Hydraulic Design (NFPA 13) For systems designed to NFPA 13, the number of design sprinklers is to be the four most hydraulically demanding sprinklers. The minimum required discharge from each of the four sprinklers is to be the greater of the following: The flow rates given in Tables A or B as a function of temperature rating and the maximum allowable coverage area. A minimum discharge of 0.1 gpm/ft2 over the "design area" comprised of the four most hydraulically demanding sprinklers for actual coverage areas protected by the four sprinklers. The number of "design sprinklers" specified in NFPA 13 for wet pipe systems is to be applied when designing dry pipe systems. Dry Pipe System Water Delivery When using the Series LFII Residential Sprinklers (1Y2234) in dry pipe sprin- kler systems, the time for water delivery must not exceed 15 seconds for the most remote operating sprinkler. Obstruction to Water Distribution Sprnklers are to be located in accor- dance with the obstruction rules of NFPA 13D, 13R, and 13 as appli- cable for residential sprinklers as well as with the obstruction criteria described within the Technical Data Sheet TFP490. Operational Sensitivity Sprinklers are to be installed with a deflector-to-ceiling distance of 1-1/4 to 4 inches. Sprinkler Spacing The minimum spacing between sprin- klers is 8 feet (2,4 m). The maximum spacing between sprinklers cannot exceed the length of the coverage area (Table A or B) being hydraulically calculated (e.g., maximum 12 feet for a 12 ft. x 12 ft. coverage area, or 20 feet for a 20 ft. x 20 ft. coverage area). Installation The TYCO RAPID RESPONSE Series LFII Residential Pendent and Recessed Pendent Sprinklers (1Y2234) must be installed in accor- dance with this section: General Instructions Do not install any bulb type sprin- kler if the bulb is cracked or there is a loss of liquid from the bulb. With the sprinkler held horizontally, a small air bubble should be present. The diam- eter of the air bubble is approximately 1/16 inch (1,6 mm). A leak-tight 1/2 inch NPT sprinkler joint should be obtained by applying a minimum-to-maximum torque of 7 to 14 ft.-lbs. (9,5 to 19,0 Nm). Higher levels of torque can distort the sprin- kler Inlet with consequent leakage or impairment of the sprinkler. Do not attempt to compensate for insufficient adjustment in an Escutcheon Plate by under- or over- tightening the sprinkler. Re-adjust the position of the sprinkler fitting to suit. Series LFII Residential Pendent Sprinklers The Series LFII Residential Pendent Sprinklers must be installed in accor- dance with the following instructions. Step 1. Install pendent sprinklers in the pendent position with the deflector parallel to the ceiling. Step 2. With pipe thread sealant applied to the pipe 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 3). With reference to Figure 1, apply the W-Type 6 Sprinkler Wrench to the wrench flats. Series LFll Residential Recessed Pendent Sprinklers The Series LFII Residential Recessed Pendent Sprinklers must be installed in accordance with the following instructions. Step A. Install recessed pendent sprinklers in the pendent position with the deflector parallel to the ceiling. Step B. After installing the Style 20 Mounting Plate over the sprinkler threads and with pipe thread sealant applied to the pipe threads, hand- tighten the sprinkler into the sprinkler fitting. (continued on Page 5) TFP400 Page 4 of 6 For coverage area dimensions less than or between those indicated, use the minimum required flow for the next highest coverage area for which hydraulic design criteria are stated.

Care and Maintenance The TYCO RAPID RESPONSE Series LFll Residential Pendent and Recessed Pendent Sprinklers (TY2234) must be maintained and serviced 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, permission to shut down the affected fire protection system must be obtained 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 sprinklers are not used for hanging any objects and that the sprinklers are only cleaned by means of gently dusting with a feather duster; other- wise, non-operation in the event of a fire or inadvertent operation may result. Sprinklers which are found to be leaking or exhibiting visible signs of corrosion 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 damage to the sprinklers - before, during, and after installation. Sprinklers damaged 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 inspection, testing, and mainte- nance of their fire protection system and devices in compliance with this document, as well as with the appli- cable standards of the National Fire Protection Association (e.g., NFPA 25), in addition to the standards of any authorities having jurisdiction.
