The proposed underground fire system has been designed to support a high bay warehouse. The proposed private fire main will consist of a 8" Polyvinyl chloride (PVC) fire main that will service 3-6" hydrants, along with the sprinkler system in the proposed building. CRITERIA AND METHODOLOGY The modeling of the onsite fire service lines was completed using the EPANET 2.0 program (EPANET). Usage of the underground fire plans by excel engineering provided the scaled distances for the project. The schematic used in EPANET can be found on Attachment 1. Available Pressures in the Street A water availability form for the project was provided by the Carlsbad Fire Department. This form lists the available flow capacity of the existing pipeline in Lionshead Avenue. This form is included in Attachement 4 of this report. Head Loss Across Fittings Minor loses encountered in the Ductile Iron Pipe (DIP) fittings along the pipelines were neglected in the model (i.e. elbows, tees, etc.). The head loss (HL) across the backflow apparatus was addressed and modeled using the method described below. The Ames double check detector assembly (DCDA) was modeled as a general purpose valve (GPV) in series with a check valve. The HL curve can be found on the specification sheet for the Watts DCDA on Attachment 2. This information was used to develop Figure 1 below, which displays the HL curve created for usage in EPANET to model the flow within the system. Additional information for the proposed backflow device can be found on Attachment 2.

Modeled Demand Flows To ensure the onsite hydraulics can supply adequate flow to the system during a fire event, Excel Engineering tested the main scenario. With the fire flow system criteria provided in the NFPA guidelines, the following test scenario was conducted: Scenario 1 - For this scenario, a demand of 1,500 gpm was supplied to the buildings fire sprinkler system. CALCULATONS AND CONCLUSIONS This performed analysis confirms that the underground fire distribution system will be adequate to provide fire flows to the site for the scenario in accordance with the following requirements: Minimum residual pressure for the project shall be 20 pounds per square inch (psi) during fire flow demand. Pipe velocities shall not exceed 10 feet per second (fps). The velocity and pressure requirements were met for this project. For this scenario, the highest velocity found in the system was in multiple pipes. This velocity was recorded as 9.57 fps. See Attachment 3. Minimum Pressure -For this scenario, the minimum pressure in the system is found in Junction 7. The recorded pressure was 115.04 psi.

ES-A-3000SS Series 3000SS A M E S Double Check Detector Assemblies FIRE & WATERWORKS Sizes: 21/2 - 12" (65 - 300mm) Series 3000SS Double Check Detector Assemblies are designed for use in accordance with water utility non-health hazard containment requirements. It is mandatory to prevent the reverseflowof fire protection system substances, i.e., glycerin wetting agents, stagnantwater and water of non-potable quality from being pumped or siphoned into the potable water supply. Specifications A Double Check Detector Assembly shall be installed on fire protection systems when connected to a drinking water supply. Degree of hazard present is determined by the local authority having jurisdiction. The main valve body shall be manufactured from 300 Series stainless steel to provide corrosion resistance, 100% lead free* through the waterway. The double check detector assembly consists of two independently operat- ing, spring loaded check valves, two UL, FM, OSY resilient seated gate valves, and bypass assembly. The bypass assembly consists of a meter (cubic ft. or gallons), a double check including shutoff valves and required test cocks. Each cam-check shall be internally loaded and provide a positive drip tight closure against reverse flow. Cam-check includes a stainless steel cam arm and spring, rubber faced disc and a replaceable seat. There shall be no brass or bronze parts used within the cam-check valve assembly. The check valve seats shall be of molded thermoplastic construction. The use of seat screws as a retention method is prohibited. All internal parts shall be accessible through a single cover on the valve assembly. The valve cover shall be held in place through the use of a single grooved style two-bolt coupling. The bypass line shall be hydraulically sized to accurately measure low flow. The bypass line shall con- sist of a meter, a small diameter double check assembly with test cocks and isolation valves. The bypass line double check valve shall have two independently operating modular poppet check valves, and top mounted test cocks. The assembly shall be an Ames 3000SS.
