Best Regards, David Jacobs Chairman Anchor Audio, Inc. CITY OF LA'AI Fire Department www.carlsbadca.gov April 7, 2011 Anchor Audio Mr. David Jacobson 5931 Darwin Court Carlsbad, CA 92008 Request for Alternate Materials, Means and Methods - 5931 Darwin Court, Carlsbad I have received and reviewed the Technical Opinion Report of April 4, 2011, prepared by Mr. Robert Caputo. In which you requested the use of an alternative materials, means and methods consideration for the expansion of the subject property as allowed for in California Fire Code § 111.2.4. In the case of Anchor Audio, you are asking for alternative means to store Group B plastics in the warehouse as part of your stock for the assembly of your final products. Given that this building is equipped with a sprinkler system that is designed for Extra-Hazard Group I and 2 commodities, I find no reason to prohibit the storage of those Group B plastic products used in your assembly processes, so long as any one of the following items are complied with: You may construct an interior room constructed of materials that afford at a minimum a 1-hour fire rating with self closing doors of a 3/4-hour rating and protected with overhead and in-rack fire sprinklers, if pallet racking is to be used. Provide an outside storage container separated from the building by no less than 10-feet and no less than 25-feet from any building openings. You would also be required to obtain written approval from the building owner, written approval from the Building Owner's Association, and written approval from the City of Carlsbad-Planning Department. You may store in an open area within the warehouse set aside and delineated for on floor pallet storage. You may store up to 5-feet in height and shall not exceed 2500-square feet of area for the storage of Group B plastics. This area must be separated from all other storage, including pallet racks by no less than 8- feet in any one direction. In addition, at no fault of Anchor Audio, Inc., its officers or employees, the existing overhead fire sprinkler system shall be required to be re-fitted so that the sprinkler deflectors are spaced the proper distance from the roof system and any other structural member or wall. It shall be so stated that regardless of who is currently or in the future occupying this building, the re-fitment of the overhead sprinkler system is required. The fact that this discrepancy was discovered during one of the many inspections conducted during the tenant improvement construction process for occupancy by Anchor Audio, should not be of a consequence towards Anchor Audio, that this issue would have at some point in time been discovered and correction would have been required.

All other provisions of the Fire Protection Technical Report remain intact, regardless of the approval or rejection of this proposal. Negative Impact Declaration: This request will be based upon Factory Mutual Global (FM) data sheets and full scale testing of specific types of plastics which are used for speaker housings by Anchor Audio. While the FM data sheets are utilized as justification for this alternative means and measures proposal, it should be noted that FM does not insure this building or its contents nor has FM or any of its representatives reviewed this specific proposal. The speaker housings are made of three specific thermoplastics which include acrylonitrile- butadiene-styrene (ABS), polycarbonate and polypropylene all of which are stored in cardboard cartons on standard pallet racks and/or on the floor level with limited heights as described below. Thermoplastics are characterized as plastics which become soft when sufficiently heated and harden when cooled, no matter how often the process is repeated. Overview. As stated in the original technical report, Anchor Audio, Inc. occupies the building located at 5931 Darwin Ct., Carlsbad, CA 92008, where they house the firm's corporate offices including sales, marketing and administrative functions as well as assembly of electronic components, defined by NFPA 13 §5.3.1 as Ordinary Hazard Group I occupancy. Fire & Life Safety 9 Consulting • Planning 9 Analysis • Inspections Consolidated Fireprote.ction Consultants Anchor Audio (Cont) Page 2 This facility is a free standing building approximately 32,000 ft2 in total. The building is protected with an approved fire sprinkler system designed to deliver a density of .45 gpm/3000 ft2. Building Construction, Occupancy Classification and Fire Protection: Building Type of Construction: V-N fully sprinklered Occupancy Classifications: Total Building Area: 15t Floor Offices 2' Floor Offices Ceiling Height: Ceiling Level Sprinkler Density: B/Si - 32,000 ft2 (approx) 6,427 ft2 (approx) 5,733 ft2 (approx) 28 ft 0.45 gpm/3000 ft2 This proposed alternative means and measures for the protection of plastic commodities stored in cartons are based upon FM data sheet 8-1 which addresses commodity classifications. While the fire code considers ABS, polycarbonate and polyethylene as Group A Plastics, Factory Mutual classifies thermoplastics including polyethylene, polycarbonate and acrylics as Group B plastics, which are protected as Class IV Commodities by FM requirements and by NFPA 13, 2010 edition (and prior). The following excerpts from FM Data Sheet 8-1 are provided for your use in review and are the technical support basis of our request: 2.2.6 Plastics 2.2.6.1 General 2.2.6.1.1 Because of the large number of plastics, the complexity of their nomenclature, and the ease of changing burning characteristics with additives, great care should be used in classifying plastics. 2.2.6.1.2 The heat release rate (Btu/min or kW) can be three to five times greater for plastic materials than for a similar arrangement of ordinary combustibles. 2.2.6.1.3 The heat of combustion of ordinary combustibles (e.g., wood or paper) generally ranges between 6,000 and 8,000 Btu/lb (13,960-18,600 Id/kg). The heat of combustion for plastics generally ranges between 12,000 and 20,000 Btu/lb (27,910-46,520 Id/kg). The burning rate of a commodity is dependent on many things, but plastic materials generally exhibit higher maximum burning rates than similarly arranged ordinary combustibles. This difference can be two to three times higher for many plastic products. Fire & Life Safety • Consulting 9 Planning • Analysis • Inspections Consolidated Fireprotect.ion Consultants Anchor Audio (Cont) Page 3 2.2.6.1.4 The overall hazard of a commodity is a function of its heat release rate (Btu/min or kW). As the heat release rate increases so does the hazard. Plastics pose a significantly greater hazard than ordinary combustibles; therefore, plastics should be classified separately and carefully. 2.2.6.1.5 Although there are a large number of plastic materials, five generic plastics products account for a large majority of the total plastics produced: polystyrene, polyethylene, polypropylene, polyester, and polyvinylchioride. 2.2.6.2 Thermoplastic and Thérmoset Plastics 2.2.6.2.1 There are two large groups of plastics: thermoplastic and thermoset plastics. Thermoplastics become soft when sufficiently heated and harden when cooled, no matter how often the process is repeated. Thermosets set into permanent shape from the heat and pressure applied to them during manufacturing. Reheating will not soften these materials. 2.2.6.3 Unexpanded and Expanded Plastic Materials 2.2.6.3.1 Plastic materials are manufactured into two basic forms, unexpanded and expanded. Unexpanded plastics are a solid high-density product such as polyethylene film, polystyrene toys, polyester and polystyrene plastic tote bins, polyethylene 55 gal (209 I) drums or smaller containers, etc. 2.2.6.3.2 Expanded plastics are generally a low-density product and are commonly called "foam plastics" such as polystyrene foam coffee cups, polystyrene foam packaging material, and polyethylene and polypropylene foam sheeting packaging material. 2.2.6.3.3 Generally the heat release rate for expanded plastics is greater than for unexpanded plastics due mainly to the relatively low density and resulting high burning rate. The heat of combustion for a given plastic material is about the same whether it is expanded or unexpanded. 2.2.6.4 Group A Plastics 2.2.6.4.1 Group A plastic products are those that incorporate plastic materials having a heat of combustion (Btu/lb or Id/kg) that is much higher than that of ordinary combustibles, and burning rate (lb/mm or kg/mm) higher than Group B plastics. Plastics that would normally fall into this category are thermoplastic polystyrene and acrylonitrile-butadiene-styrene (ABS). 2.2.6.4.2 Paraffin, natural "beeswax," and polyurethane also fall into this category. 2.2.6.5 Group B Plastics 2.2.6.5.1 Group B plastic products are those that incorporate plastic materials having heat release rates higher than ordinary combustibles, but less than Group A plastics. The heat of combustion for many Group B plastic materials may be as high or sometimes higher than some Group A plastic materials, but given the same configuration, the burning rate of a Group B plastic is lower than that for Group A plastic. Fire & Life Safety ' Consulting • Planning • Analysis • Inspections Consolidated Fireprotection Consultants Anchor Audio (Cont) Page 4 Below are comparison burning rates for similarly arranged polystyrene (Group A) and polypropylene (Group B) materials: Polystyrene-440 lb/mm (200 kg/mm) Polypropylene-233 lb/mm (106 kg/mm) The above are comparisons for a given storage arrangement, and these values will change depending on height, type of storage, ventilation, etc. Plastic materials that fall into the Group B category are thermosettin polyesters and thermoplastics such as polyethylene, polypropylene, polycarbonate, acrylics, cellulosics and nyn (Note that polycarbonate and polypropylene are two of the three plastics stored and used by Anchor) 2.2.6.6 Group C Plastics Group C plastic products are those that incorporate plastic materials having a heat of combustion and a burning rate similar to those of ordinary combustibles. Plastic materials that would normally fall into this category are thermoplastic fluorocarbons and most thermosets such as alkyd, amino, casein, phenolics, and silicones. Group C plastics should be treated and protected as Class 3 commodities. When these materials are combined with other materials that would change the burning characteristics of the commodity, careful analysis is needed to determine if the product remains a Group C plastic commodity. 2.2.6.7 Polyurethane Polyurethane has different chemical properties than other plastic materials tested: however, fires in each are very similar. When expanded polyurethane is stored un-cartoned, protect it as a Group A expanded plastic. However, when, expanded polyurethane is used inside cartons, protect it as a Group A unexpanded plastic material. Intermediate and full scale tests have shown that cartoned expanded polyurethane presents no greater hazard than an unexpanded plastic commodity. However, similar testing with other expanded plastic materials such as cartoned expanded polystyrene presented a greater hazard than unexpanded plastic. Protect polyurethane-padded innerspring mattresses as a Class 4 commodity. Protect cartoned solid-core polyurethane mattresses as a Group A unexpanded plastic. Protect un-cartoned solid-core polyurethane mattresses as a Group A expanded plastic. 2.2.7.2 Mixed Commodities 2.2.7.2.1 Generally in warehouse environments a variety of commodities is being stored. It is tempting to "average the commodities", but using this averaging method to determine sprinkler protection recommendations is not adequate. Protection for the highest hazard commodity should be provided. There are a number of reasons for providing protection for the highest hazard commodity: Fire tests in the early 1980s showed that replacing one tier of a four-tier-high rack array with a higher hazard commodity produced a hazard much higher than that of a rack filled 100% with the lower hazard commodity. Fire tests where sprinkler protection is adequate for the specific commodity, typically burn only about a 200-300 ft2 (18.6-27.9 m2) area of the commodity tested. Only a small amount of material has to burn to create relatively large sprinkler operating areas (1500-2500 ft2 [140-230 m2) which means it wouldn't take much of a high hazard commodity to overtax a sprinkler system designed for a lower hazard commodity. Fire & Life Safety • Consulting • Planning • Analysis • Inspections Consolidated Fire-protection Consultants Anchor Audio (Cont) Page 5 3. Using the "averaging method" means continual monitoring to ensure no concentration of more than a few pallet loads of higher hazard commodities. In normal warehouse environments adequate monitoring is very difficult at best and generally not feasible. 2.2.7.2.2 Considering all the above, protection should be based on —the highest hazard commodity. An - - alternative is to segregate the high hazard commodities and protect them accordingly. However, keeping thel high hazard commodities properly segregated can be very difficult in normal warehouse operations. 2.2.7.2.3 In general, where a mixture of commodities is stored, protection should be based on the highest hazard commodity. However there may be isolated cases where the amount of higher hazard commodity is very small and its location can be strictly controlled (via computerization), where the loss expectancy determination may be based on a lesser commodity classification. 2.2.7.2.4 If it can be assumed that 1) at no time will concentrations of the higher hazard commodity exceed 25% in any single rack bay or stack of solid/palletized storage, and 2) There will be no case where a pallet load of a higher hazard commodity will be located directly above another pallet load of the higher hazard commodity, then evaluation may be based on a composite of the two commodities involved. 2.2.7.2.5 For example, scattered small amounts (as described in the previous paragraph) of plastics mixed with Class 1 or Class 2 commodity may be evaluated as a Class 4 commodity. Small amounts of Class 4 commodity mixed with Class 1 or Class 2 commodity may be evaluated as a Class 3 commodity. Plastics mixed with Class 3 or 4 commodities should be evaluated as plastics and Class 4 commodities mixed with Class 3 commodities should be evaluated as a Class 4 commodity. Cases where commodity mixtures can be so strictly controlled will be extremely rare. 02004 Factory Mutual Insurance Company. All rights reserved. The NFPA 13 Design Criteria Committee has determined through full scale fire testing that rack storage of plastic and rubber commodities is more challenging to ceiling only sprinklers than that for the same height and clearance of solid-piled or palletized storage. As such, ceiling-only protection criteria specified for rack storage of plastic and rubber commodities is also permitted to be used for solid-piled and palletized storage of the same commodity, at the same height and clearance. If the polycarbonate and polypropylene products can be considered as Group B Plastics as suggested by the FM Data sheet 8-1, the requirements for sprinkler protection for rack storage based upon Figure 17.1.2.1 (below) are based upon Class IV commodities.

Portable Sound Systems at the direction of Alicia Garibay. This report will address the processes performed at this facility for the manufacture of speakers and portable public address systems including high piled and pallet rack storage of raw materials and finished goods stored within this facility. Hazardous material inventories including their use and storage will also be addressed herein. Anchor Portable Sound Systems assembles public address systems utilizing multiple components manufactured by subcontractors off-site including cabinets and face covers. The finished products are sold through distributors and through direct internet sales shipped from this location. The components of these systems include printed circuit boards assembled at this site with standard electronic components including silicon chips, capacitors, diodes and resistors which are assembled and soldered in a closed, vented system addressed below. Some open hand soldering is also performed, primarily for repairs of components or touch up of printed circuit board after exiting the solder wave machine unit. Wiring harnesses are also manufactured on site for use in the product systems however most of these harnesses include swaged or crimp style ends without solder paste or heat used in assembly. Many of the public address systems are manufactured to function on both AC and DC power., As such, small 12 volt sealed batteries are stored with about 30 batteries being charged each day for "just in time" use in the assembled systems.

This facility is a free standing building approximately 32,000 ft2 in total. The building is protected with an approved fire sprinkler system designed to deliver a density of .45 gpm/3000 ft2. Building Construction, Occupancy Classification and Fire Protection: Building Type of Construction: V-N fully sprinklered Occupancy Classifications: B/Si Total Building Area: 32,000 ft2 (approx) 1 Floor Offices 6,427 ft2 (approx) 2' Floor Offices 5,733 ft2 (approx) Ceiling Height: 28 ft Ceiling Level Sprinkler Density: 0.45 gpm/3000 ft2 Commodity Classification Summary: Fire testing for storage of mixed commodities has shown that the fire takes on the characteristics of the higher commodity. For that reason, the requirements of NFPA 13 §5.6.1.2 were developed to provide guidance on choosing the appropriate commodity classification to govern sprinkler system design. As such, the fire sprinkler system protection requirements are required to be based on the highest classified commodity and storage arrangement and not the overall commodity mix in a fire area. As such, the fire sprinkler design density will be based upon un-expanded Group A Plastics throughout the facility. Raw materials include speaker cabinets and covers manufactured of ABS, polycarbonate, polyethylene and polypropylene, depending upon the size and type of the speaker.

NFPA test data is limited for plastics stored with clearances greater than 10 ft. It should be assumed that if protection is adequate for a given storage height in a building of a given height, the same protection will protect storage of any lesser height in the same building. For example, protection adequate for 20 ft storage in a 30 ft building [10 ft clearance] would also protect 15 ft storage in a 30 ft building [15 ft clearance] the protection criteria for storage 5 ft higher than the indicated height with 10 ft clearance. Table 12.2.3.1.1 is based on tests that were conducted primarily with high temperature rated, K-8 orifice sprinklers. Other tests have demonstrated that, where sprinklers are used with orifices greater than K-8, ordinary-temperature sprinklers are acceptable Table A.12.2.3.1 explains and provides an example of the method and procedure to follow in using this standard to determine proper protection for Group A plastics. Fire & Life Safety 9 Consulting • Planning • Analysis • Inspections Consolidated Fireprotection Consultants Anchor Audio (Cont) Page 9 Per NFPA 13 §12.2.3.1.7, when applying Table 12.2.3.1.6 the design area is required to be a minimum of 2500 ft2. As noted in § 12.3.1.13 flue spaces within double-row and multiple-row racks without solid shelves, a longitudinal (back-to-back clearance between loads) flue space is not be required. Nominal 6" transverse flue spaces between loads and at-rack uprights shall be maintained in single-row, double- row, and multiple-row racks. Random variations in the width of flue spaces or in their vertical alignment are permitted. The NFPA 13 Design Criteria Committee has determined through full scale fire testing that rack storage of plastic and rubber commodities is more challenging to ceiling only sprinklers than that for the same height and clearance of solid-piled or palletized storage. As such, ceiling-only protection criteria specified for rack storage of plastic and rubber commodities is also permitted to be used for solid-piled and palletized storage of the same commodity, at the same height and clearance. p.-' --- As an alternative, the owner/tenant may replace the existing sprinklers throughout the warehouse/assembly area with Control Mode Specific Application (CMSA) K-16.8 sprinklers7and) recalculate the system based upon the most demanding 15 sprinklers operating at a minimum pressure of 22 psi. - As in Option #2 for rack storage arrangements above, this option will permit storage of all products and commodities up to 20 ft high in a building height up to 30 ft based on NFPA 13, Table 12.2.3.2.1(b) CMSA Sprinkler Design Criteria for Palletized and Solid-Piled Storage of Plastic and Rubber Commodities below: Thblc 12.23.2.1(b) SpeefficAlpomdon caalxol ModE (19.8 K-I?ctor) sprinkkrDcsigfl Qireria for LllcUzed and Suild-Plied Storage of Plastie and Rubber Comniodilles Nimb.fi3ign Mxdmm Builaw Spu.b1iminna HoueStri Critmi GainiodLty chm SLe Helehi Ubt Type oF 533Lea op—du Demand Duinioz (hnius) —rSuppy ft s ftUL 10 Pd (IL? bur) I 22 ji (1.5bar) L/ciia PI1ctiv,iI Ciirti,ucJ or cxpod 25 7.6 50 9.1 WcL - 15 500 1900 2 sublpilr CrtonccIar cxpa5d 25 7.6 50 9.1 WcI - 15 500 1900 10. uncLpn&d I&SLics Fire & Life Safety • Consulting 9 Planning • Analysis • Inspections Consolidated Fire-protection Consultants Anchor Audio (Cont) Page 10 Electronic Components Assembly: Anchor Audio assembles electronic components for use in its speakers and public address systems including printed circuit boards (PCB's) memory chips, resistors and capacitors which have a solder paste applied to their underside, where the computer chips or parts poke through. The chips, resistors and capacitors are placed onto the board and the assembly is run through an enclosed, reflow soldering convection oven which melts the solder paste, connecting the computer chips and components. The manufacturing process utilizes electricity and compressed air to hold the chips and components in place before placement on the PCB. Industry standards for this manufacturing process can utilize liquid nitrogen however, there will not be any liquid nitrogen used at this site. Completed boards are inspected and tested after exiting the solder wave machine with any required touchup or bridge removal performed by hand. Fume Exhaust - Heating & Soldering Operations: The solder paste is lead free, containing tin, silver, copper and rosin. PCB's are heated in a reflow heat wave oven. Small amounts of the solder paste compound are vaporized and collected in a filter system located within the unit. All solids are retained by the filter, which is exchanged as needed and returned to the supplier for extraction of precious metals and recycling. The exhaust air is clean with the exception of trace amounts of rosin based residue. Rosin is a substance made from tree sap from Pine trees, which is used in solder as an oxide remover during the actual melting of the solder. Trace amounts of rosin collect on the walls of the exhaust duct and is cleaned as needed. The reflow oven soldering activities are provide with exhaust hoods and ducting through the roof, venting to atmosphere as prescribed by the equipment product brochures and literature included with this report. The test stations (QA/QC) perform solder bridge removal and any required minor repairs to PCB's utilizing lead-free solder and do not require individual fume exhaust hoods. A repair station with a fume exhaust hood (pictured below) is present, immediately adjacent to the reflow oven equipment. This station is used for repairs of returned equipment, random testing and touch up. The exhaust fan is rated 4,000 cfm as indicated in the report prepared by CA Licensed HVAC contractor, Eddie Ortega's Global Development, below and complies with requirements of CIVIC §506.9: Fire & Life Safety • Consulting • Planning • Analysis • Inspections Consolidated Fireprotection Consultants Anchor Audio (Cont) Page 11 ae-040Z&- 4236 DEl.

Caputo, CFPS, CET President Attachments Fire & Life Safety • Consulting • Planning • Analysis 9 Inspections Consolidated Fireprotection Consultants Anchor Audio (Cont) Page 17 Smoke & Heat Vents: CFC Table 2306.2 requires smoke and heat removal for high hazard occupancies based upon a floor area to vent ratio of 50:1. The warehouse/manufacturing area is approximately 25,573 ft2 in total area of which, approximately 1/3rd is utilized for storage. There are 10 approved, vented skylights randomly located representing 310 ft2 of vent for approximately 10,300 ft2 of storage area. [10,300 —* 50= 206 ft2 required vent area]. Hydrants/Access Roadways: Hydrants and fire department access roadways will continue to be maintained unobstructed and accessible to emergency response crews. Summary of Owner/Tenant's Obligations and Required Changes: O Option #1: Re-calculate existing sprinkler system to deliver a density of 0.70 gpm over the most demanding 2,500 ft2 which will accommodate rack storage up to 20 ft and palletized storage to 15 ft high as noted above. O Option #2: Replace existing ceiling sprinklers with K-16.8 CMSA sprinklers and provide• hydraulic calculations proving the hydraulic demand for the 15 most demanding sprinklers flowing with a minimum discharge pressure of 22 psi. This option permits all storage up to 20 ft in a 30 ft building. O Option #3: add one level of in rack sprinklers below to tier of rack storage and limit palletized storage on the floor to 5 ft high. Regardless of the option selected for the sprinkler system density upgrade required, it has been discovered through the course of this evaluation that the existing sprinklers are installed at a greater distance below the ceiling (roof) than is permitted by NFPA 13, 2002 edition § 8.6.4 which prescribes the deflector position (standard spray sprinkler pendent and upright) under unobstructed construction to be a minimum oil" and a maximum of 12" throughout the area of coverage of the sprinkler. The sprinkler contractor shall be responsible to raise the sprinkler system branch line piping or add sprig-ups to position sprinklers so deflectors are compliant with NFPA 13 §8.6.4.

Since the existing design criteria are 0.45 gpm/3000 ft2. this objective cannot be met. The tenant proposes to either construct a cutoff room with walls and a ceiling with a 1-hour rating for storage of the ABS plastics (only) or store these products outside of the building in a metal storage container. As a third option1 if acceptable to CFD, the owner would commit to limiting the storage of the ABS product to no more than 5 ft high on the floor either in the lowest level of the pallet racks or out in the open a minimum of 8 ft horizontally from any pallet rack. Fire & Life Safety • Consulting • Planning ' Analysis • Inspections Consolidated Firepiotection Consultartes. Anchor Audio (Cont) Page 9 Regardless of whether the options for alternative protection provided herein are acceptable to CFD, the owner and/or tenant shall be required to adjust the existing sprinklers so they comply with NFPA 13 maximum allowable distance from the ceiling or roof deck as called out in the technical report. In addition, if accepted, the tenant shall be required to protect any steel columns located within the rack storage area by either 1 hour fireproofing or a sidewall sprinkler directed to one side of the column at the 15 ft level. Flow from these sprinklers is not required to be added to the system demand for hydraulic calculations. If this proposal is not acceptable to CFD, the owner requests additional time (60 days) to pursue the original technical report option #3, which would add one level of in rack sprinklers below to tier of rack storage and limit palletized (non-rack) storage on the floor to 5 ft high. Conclusion: As noted in NFPA 13 (2007 & 2010) § 1.5, nothing in this standard is intended to prevent the use of systems, methods, or devices of equivalent or superior quality, strength, fire resistance, effectiveness, durability, and safety over those prescribed by this standard. We hope we have documented our claim that the proposed alternative protection approach is supported with documentation showing the level of safety will not be lowered.
