<br /> QUELL SYSTEM
<br /> CLASS II COMMODITIES
<br /> GENERAL GUIDELINES:
<br /> Ultra K17(TY7103)Sprinklers with a 286°F(141°G)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 II 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 10002(9,3 m7 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 /> Notes:
<br /> a. The minimum recommended number of designsprinklers is to be confirmed with authority having jurisdiction.Refer to the appropr
<br /> iate i to appen-
<br /> dix material.When spinkler coverage areas of 100 tt (9,3 m')are used for all 25 design sprinklers,the resulling designa area is
<br /> 2SanWode(of design
<br /> spunkier coverage areas less than 1001F(9,3 mq are utilized the design area is not be less than 2250112(209 m')', gn
<br /> sprinklers may need to be increased accordingly.
<br /> b.The maximum water delivery time(operating time per SprinkFOr 0)shall be calculated so as to assure the minimum sprinkler design pressure is
<br /> .available at each of the most h draulical demandinglour sprinklers within the noted time(when applyingthe water deliverycalculation enter the
