FireLite SLC Wiring Manual — P/N 51309:P4 9/17/2014 27NFPA Style 6 SLC Using Isolator Modules SLC Circuits with Isolators4.3 NFPA Style 6 SLC Using Isolator ModulesA variation of Style 6 operation using isolator modules to protect a section of the SLC. By flankingeach group of devices with an I300 fault isolator module each group is protected from faults thatmay occur in the other groups. For example, a fault in Section B will not effect Sections A & C.The isolator modules on either side of Section B will open the loop. Section A will still operatefrom power on the SLC Out side and Section C will operate from the SLC Return side.• A combination of isolator modules and isolator bases may be used.• T-tapping is NOT allowed within the Style 6 configuration.• Isolator modules shall be within 20 feet (6.1 meters) of device and must be enclosed in metalconduit.Figure 4.5 NFPA Style 6 SLC Using Isolator ModulesSLC Out SLC ReturnSLC-style6iso.wmfControl PanelTwo-wireAddressableDetectorSection BSection CSection AIsolatorModuleIsolatorModuleIsolatorModuleAdditional isolator module required when first device in thesection is more than 20 feet from the control panel.IsolatorModuleIsolatorModuleIsolatorModuleAddressablePull Station
