Appendix A: Releasing Applications Overview26 AFP-300/AFP-400 Programming PN 50259:C1 06/19/97Appendix A: Releasing ApplicationsOverviewNote: Refer to Programming inthis Appendix for detailedinformation on these releasingfunctionsThe control panel includes ten software zones that you can use to control releasingfunctions. Releasing zones R0-R9—reserved for special releasing functions—allow upto ten release operations. Each releasing zone operates independently, and is fullyprogrammable. From the Special Function Change Screen (Figure 21), select releasingfunctions (R0-R9) to display the Releasing Function screen:Figure 41 Releasing Function ScreenNote: “Soak” equals theelapsed time, in seconds,between activation of a zoneand shut down of the releasingzone valves.Each releasing zone includes four releasing functions, outlined in Table 25:Table 25 Releasing FunctionsNFPA StandardsYou can use the AFP-300/AFP-400 as a control panel for agent release or preaction/deluge control applications. When used with compatible, UL-listed actuating andinitiating devices, the control panel meets the requirements of the following NFPAstandards:Table 26 NFPA Standards for Releasing ApplicationsPRG RELEASE FUNCT RELEASE CONTROLDELAY=XX ABORT=XXX CROSS=N SOAK=XXXX R05Function Lets You...Delay Program a 0-60-second delay. The delay equals the time that must elapsebetween activating an initiating device and activating all zones mapped to theactive initiating device.Abort Select a 3-letter Abort switch-type code (ULI, IRI, NYC, or AHJ) that adds adelay time to a releasing zone, or prevents a release of a releasing zone (seeTable 27 on page 27).Cross Select one of three types of cross zoning or “N” (not used). Cross zoningrequires tripping two or more devices to activate the outputs mapped to one ofthe releasing zones.Soak Select a Soak timer (0-9999 seconds) or “0” (not used).Standard CoversNFPA 12 CO2 Extinguishing SystemsNFPA 12A Halon 1301 Extinguishing SystemsNFPA 12B Halon 1211 Extinguishing SystemsNFPA 13 Sprinkler SystemsNFPA 15 Water Spray SystemsNFPA 16 Foam-water Deluge and Foam-water Spray SystemsNFPA 17 Dry Chemical Extinguishing SystemsNFPA 17A Wet Chemical Extinguishing SystemsNFPA 2001 Clean Agent Fire Extinguishing Systemswww.PDF-Zoo.com
