It is divided into four (4) sections: Cylinder Sizing Nozzle Coverage and Placement Piping Limitations Detector Requirements Each of these sections must be completed before attempting any installation. SYSTEM CYLINDER SIZING Each of the nozzles in the section, "Nozzle Coverage and Placement" has its own flow point value. Each of the three different agent tanks can support a maximum number of flowpoints, based on the volume of the pipe used. Select the system tank(s) by calculating the total number of flow points associated with the appliances(s), plenum, and ducts, plus the total piping volume. ' CAUTION Do not exceed the maximum number of flowpoints as shown on the Tank Chart, page 46. If the number of flow points or the pipe volume required exceeds the amounts shown, additional tank(s) or changes in piping design are required. NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines for determining nozzle type, positioning, and quantity for duct, plenum, and appliance protection. A. DUCT PROTECTION It is not required that the fan be shut down or the exhaust duct be dampered for the system to operate properly. Each nozzle is approved to protect exhaust ducts of unlimited length. Duct protection requires that a nozzle by positioned to dis- charge up, into the duct. The nozzle is a Part No. NL2D. The NL2D duct nozzle is a two (2) flow nozzle. A single 6 IN. INTO DUCT 2D NO LE Figure 3-1 NL2D nozzle is capable of protecting square or rectangular duct with a maximum of 100 in. perimeter, with the longest side being a maximum of 34 in. It can also protect a round duct with a maximum diameter of 31 7/8 in. Two (2)NL2D duct nozzles can protect a square or rec- tangular duct with a maximum of 150 in. perimeter, with the longest side being a maximum of 51 in. They can also pro- tect a round duct with a maximum diameter of 47 1/2 in. When two (2) NL2D duct nozzles are used to protect a single duct, the cross sectional area of the duct must be divided into two equal symmetrical areas. The nozzle must then be installed on the centerline of the area it protects and aimed directly into the duct opening. The nozzle(s) must be installed on the centerline of the duct, with the tip located 0 to 6 in. into the opening, and aimed directly into the duct opening. See Figure 3-1. TRANSITION DUCTS The protection of non-standard ducts should be reviewed by the authority having jurisdiction. Protex Series II recommends that transition ducts be protected as follows: A. TRANSITION DUCTS - LARGER TO SMALLER In cases where the duct/plenum interface opening is larger than the final exhaust duct, measure the perimeter/diameter UL XXXX January 15, 2002 11 Part # PMAN2 rev 0 V-BANK Chapter 3 - System design B. PLENUM PROTECTION The NL1H nozzle is a one (1) flow nozzle used for plenum protection. A single NL1H nozzle can protect a plenum (with single or V-bank filters) 10 ft. long by 4 ft. wide. Dividing the length into sections equal to or less than 10 ft. in length and positioning a nozzle at the start of each section can be done to protect longer plenums. On V-bank plenums, the nozzle(s) must be located at the center of the V-bank width, 1/3 of the vertical height of the 'filters. On single filter bank plenums, the nozzle must be located 2 in. from the back edge of the filter, 1/3 down from the vertical height. For either application, the nozzle must be located within 6 in. of the end of the plenum (or module) and aimed directly down the length of the plenum. See Fig. 3-2.

APPLIANCE PROTECTION Note: When protecting appliances which are larger than sin- gle nozzle coverage, multiple nozzles can be used. Larger appliances can be divided into several modules, each equal to or smaller than single nozzle coverage. Exception: Fryers must not exceed a maximum of 864 sq. in. For modularizing fryers, refer to "Protecting Large Fryers by Dividing Their Area Into Modules," page 22. Design Index Chart and Nozzle Coverage Summary Sheet Area/ Mm.
