<br /> QUELL SYSTEM
<br /> CLASS III COMMODITIES
<br /> GENERAL GUIDELINES:
<br /> Ultra K17(1Y7103).Sprinklers with a 286°F(141°C)temperature rating must be installed in double interlock preaction systems
<br /> or dry systems for the protection of high piled storage occupancies including single,double,and multiple-row rack storage,
<br /> as well as palletized and solid piled storage,of up to Class Ill commodities as defined by NFPA 13(no open top containers).
<br /> For ceiling only protection(no in-rack sprinklers),the installation criteria is as follows:
<br /> • a minimum deflector to top of storage clearance of 36 inches(0,9 m)
<br /> • a maximum coverage area of 100 ft2(9,3 m2)per sprinkler
<br /> • a minimum coverage area of 80 ft2(7,3 m2)per sprinkler
<br /> • sprinkler spacing criteria:
<br /> 12 feet(3,6 m)maximum for unobstructed and non-combustible obstructed construction
<br /> 10 feet(3,0 m)maximum for combustible obstructed construction
<br /> 8 feet(2,4 m)minimum for all construction
<br /> • water supply duration-90 minutes minimum
<br /> Minimum Maximum Minimum Sequential Sprinkler

<br /> Notes
<br /> a. The minimum recommended number of design sprinklers is to he confirmed with the authority having jurisdiction Refer to the appropriate ap-
<br /> pendix material.When sprinkler coverage areas of 100 tl2(9,3 m2)are used for all 25 or 30 design sprinklers,the resulting design area is 250n 42
<br /> (232 m2)or 3000112(279 m2),respectively.If sprinkler coverage areas less than 100 ti2(9,3 m2)are utilized me design area is not to he less than
<br /> 2260 ft2 to 4e U,(14,6 mttherefo for rng e,,the number of(13,7 desi nor sprinksx or lers O need 2 to be251 increaseda Mr ccordingly.

<br /> b.The maximum water delivery time(operating time pry sprinkFUT-0)shall be calculated so as to assure the minirrnrm sprinkler nkler designpressure is
<br /> available at each of the must hydraulically demanding four sprinklers within the noted time(when applying the water delivery calculation enter the
<br /> sequential sprinkler opening times for each of the lour sprinkles).
<br /> c. The minimum walm delivery time(operating time per 3prinkFDT-0)shall be calculated so as to assure the minimum sprinkle assign pressure is
<br /> not available at any of the least hydraulically demanding tour sprinklers within the noted time(when applying It.water delivery calculation enter the
<br /> sequential sprinkler opening times for each of the our sprinklers.
