<br />NOZZLES <br />~ There are twelve types of discharge nozzles each designed to dis- <br />tribute the liquid agent in a uniform pattern throughout the hazard <br />area: <br />~ 1. 1W Nozzle 7. 245 Nozzle <br />2. 1 N Nozzle 8. 260 Nozzle <br />3. 1/2N Nozzle 9. 290 Nozzle <br />4. 3N Nozzle 10. 2120 Nozzle <br />5. 2W Nozzle 11. 1 F Nozzle <br />~ 6. 230 Nozzle 12. 1100 Nozzle <br /> <br />Although these nozzles are similar in appearance and have <br />certain common parts, the tip of each nozzle is designed for a <br />specific application and must only be used in those areas. See <br />Nozzle Application Chart in Section IV - System Design, for <br />individual nozzle usage. <br /> <br />3/8 -18 NPT <br />FEMALE THREAD <br /> <br />INTERNAL CUP <br />STRAINER <br />INSIDE <br /> <br /> <br />RECESS FOR- <br />BLOW OFF <br />CAP LOOP <br /> <br />NOZZLE <br />STAMPING <br /> <br />VENDOR <br />OODE <br />(IF PRESENT) <br /> <br />~ <br /> <br />RGURE13 <br />000002 <br /> <br />Nozzle Identification Chart <br />~ Nozzle <br />Nozzle Nozzle Nozzle" Flow <br />~ ~ Stamping t& Nozzle Identification <br />1W Nozzle 419336 1W 1 Chrome-Plated Body <br />1N Nozzle 419335 1N 1 Chrome-Plated Body <br />112N Nozzle 419334 1/2N 1/2 Chrome-Plated Body <br />Metal bIow-off caps are not allowed with the 1J2N nozzle <br />3N Nozzle 419338 3N 3 Chrome-Plated Body <br />2W Nozzle 419337 2W 2 Chrome-Plated Body <br />230 Nozzle 419339 230 2 Chrome-Plated Body <br />245 Nozzle 419340 245 2 Chrome-Plated Body <br />260 Nozzle 419341 260 2 Chrome-Plated Body <br />290 Nozzle 419342 290 2 Chrome-Plated Body <br />2120 Nozzle 419343 2120 2 Chrome-Plated Body <br />1F Nozzle 419333 1F 1 Chrome-Plated Body <br />1100 Nozzle 430912 1100 1 Chrome-Plated Body <br /> <br />~ * Nozzle stamping may contain an additional letter indicating a wndor's code. <br /> <br />SECTION III - SYSTEM COMPONENTS <br />UL EX. 3470 ULC CEx747 Page 3-5 <br />10-1-02 REV. 4 <br /> <br />SWIVEL ADAPTOR <br /> <br />The Swivel Adaptor Assembly, Part No. 418569, consists of a swiv- <br />el nut, swivel body and swivel ball. All are chrome-plated. The swiv- <br />el adaptor allows any nozzle to be rotated approximately 300 in all <br />directions. Swivel Adaptors must be ordered as a Swivel Adaptor <br />Shipping Assembly, Part No. 423572, which contains 25 Swivel <br />Adaptors. <br /> <br /> <br />3/8 - 18 NPT <br />FEMALE THREAD <br /> <br />FIGURE 14 <br />IIOllOO3 <br /> <br />RUBBER BLOW-oFF CAPS <br /> <br />The Rubber Blow-Off Cap, Part No. 77676, help keep the orifice of <br />the nozzle free of grease or other substances that could interfere <br />with agent distribution. A retaining strap attaches the blow-off cap <br />to the nozzle. Rubber Blow-Qff Caps must be ordered as a <br />Shipping Assembly, Part No. 77695, which contains 50 bbN-off <br />caps, or Part No. n411, which contains 12 blow-off caps. <br /> <br /> <br />~ <br /> <br />FIGURE 15 <br />0110000 <br /> <br />METAL BLOW-oFF CAP <br /> <br />Two types of metal blow-off caps are available as options to the <br />standard rubber caps. The metal cap can be used in unusually <br />high heat conditions, generally over 400 OF (204 OC). The metal <br />blow-off cap is attached to the nozzle by means of a stainless steel <br />wire which prevents it from falling into the appliance during dis- <br />charge. Shipping Assembly Part No. 79745 contains 10 metal <br />blow-off caps for use on standard, non-swivel nozzles and <br />Shipping Assembly Part No. 415568 contains 10 metal bIow-off <br />caps for use on swivel nozzles. <br /> <br />NOTICE <br />If metal blow-off caps are required for upright broil- <br />~ er or salamander protection, use (2) two 1 N noz- <br />zles (Part No. 56930) instead of 1/2N nozzles. <br /> <br />~~;:;J <br /> <br />~ STEEL WIRE <br /> <br /> <br />METAL CAP <br /> <br />FIGURE 16 <br />000152 <br />
