2.4.2 IFC2-640 with Loop Expander Modules, IFC-320
The IFC2-640 provides one SLC loop and supports a second using optional expander module
LEM-320.The IFC-320 provides one SLC loop on the FACP’s main circuit board. Terminal block
designations are the same on the circuit board for both FACPs. Loops can be either CLIP mode or
FlashScan mode. SLC loop #1 connects to TB13 on the control panel; SLC loop #2 connects to
TB1 on the LEM-320.

2.4.3 IFC-640 with Loop Expander Modules
The IFC-640 provides one SLC loop and supports a second using optional expander module
LEM-320. Loops can be either CLIP mode or FlashScan mode. SLC loop #1 connects to TB16 on
the control panel; SLC loop #2 connects to TB1 on the LEM-320.
