Control Panel Terminal Blocks

2.3.2 Measuring Total Wire Length
The total wire length in a four-wire SLC cannot exceed the limits set forth in each system's instruction manual. The figure below identi-
fies the output and return loops from SLC terminal on the control panel:

2.4.1 NFS2-3030 and NFS-3030 with LCM-320, LEM-320
The NFS-3030/NFS2-3030 supports up to five pairs of loop control and expander modules, providing from one to ten SLC loops. Loops
can be either CLIP mode or FlashScan mode. SLC loops connect to TB1 on the LCM-320 or LEM-320.
