'fhe in-rack systems will <br />be zoned to correspond with the overhead sprinkler syster.� zones. The in-rack sprinklers <br />will be equipped with U. L. listed water shields. <br />Vertical spacing, number of in-rack sprinklers and number of levels of in-rack sprinklers <br />exceed the requirements of Tabl^ 7-1 l. Vertical spacing in Table 7-11 is 15 feet actual <br />maximum spacing ��ill be 10 foot 0-inches. <br />Inside Hose Stations <br />1-1i2-inch hose valves and connections will be provided per the local Fire Department and <br />will be located throughout the building and rack system. The stations will be located on all <br />catwalk levels. Each outlet will have 1-1/2-inch val��e, 100 fee• of hose, adjustable noule <br />and tack. Hose stations will be supplied from the adjoining ceiling sprinkler system. <br />Water Supply <br />The followin6 water supply data is based on the assumption that the city can meet the <br />demand. Water test will be conducted to confirm the available supply. Based on NFPA <br />231C criteria, ceiling sprinkler system demand is based on 600 gpm flowing in the most <br />remote azea and water demand will be based on hydraulic calculations. In-rack sprinkler <br />demand is based on a minimum design flow of 30 gpm. With a design of ten sprinklers <br />operating, the total in-rack demand is 300 gpm. <br />For combination inside and outside hose streams, an allowance of at least 500 gpm must be <br />added to the sprinkler system water demand. <br />The facility is supplied by a 12-inch city main in Hazdeson Road. Recent water test data in <br />the azea indicate a static of 103 psi, a residual of 100 psi while flowing 2,432 gpm. <br />The water supply duration must be at least two hours. The system is connected to the city <br />water supply and it is anticipated that the duration requirement is met. _ <br />Based on the above requirements the total water demand, at the base of the riser is: <br />6�0 gpm for ceiling system <br />350 gpm for in-rack system <br />500 gpm for hose demand <br />Total: 1500 gpm is required for the ceiling sprinkler system. hose and in-rack sprinklers. <br />Iron Mountain <br />Everett, Washington <br />01-129b <br />L4'J <br />
