NFPA Style 6 SLC Using Isolator Modules

5.5 NFPA Style 6 SLC Using Isolator Modules
A variation of Style 6 operation using isolator modules to protect a section of the SLC. By flanking each group of devices with
fault isolator modules each group is protected from faults that may occur in the other groups. For example, a fault in Section B will not
affect Sections A & C. The isolator modules on either side of Section B will open the loop. Section A will still operate from 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 ft. (6.1 m) of device and the wire must be enclosed in metal conduit.
AFP-100, AFP-200, AM2020/AFP1010,
System 5000 with AIM-200: The first
isolator module on SLC Out and SLC
Return must be contained within the same
enclosure as the FACP, or these isolator
modules must be connected within 20 ft.
(6.1 m) of the FACP enclosure in conduit.
