Chapter 3 — System Design <br /> Page 3 -7 <br /> REV. 2 <br /> Local Application <br /> Local application consists of overhead application above the <br /> work area and protection of the duct and plenum utilizing the <br /> PCI -35ABC 3 nozzle system. <br /> 1. Local Application Overhead <br /> a. Cylinders: <br /> The Model PCI- 25sABC and PCI- 50sABC can be used for <br /> local overhead applications. <br /> b. Nozzles: <br /> The Model N -LA -ABC nozzle is used for both the <br /> PCI- 25sABC and PCI- 50sABC systems. The maximum noz- <br /> ' zle height of the Model N -LA -ABC nozzle is 10 ft. (3 m). The <br /> minimum nozzle height of the Model N -LA -ABC nozzle is <br /> • 7.5 ft. (2.3 m). <br /> Note: Nozzle height is measured from the hazard surface to <br /> the closest point of the nozzle in the installed position. <br /> c. Temperature Range: <br /> The operating temperature range for the dry chemical cylin- <br /> der assembly used for overhead applications is 32 °F to <br /> 120 °F (0 °C to 48 °C). <br /> d. Piping Requirements: <br /> Piping diagrams include limitations on pipe length and fit- <br /> tings. <br /> e. Nozzle Placement and Coverage: <br /> The Model N -LA -ABC nozzle has been developed to pro- <br /> vide local application of extinguishing agent from an over- <br /> ► head position. This nozzle will protect a hazard area of <br /> • 25 sq. ft. (2.3 sq. m) with a 5 ft. (1.5 m) maximum side. <br /> ULEX 3437 CEx732 <br /> March 17, 2004 <br />
