What is the maximum SLC loop and device capacity of the NFS2-3030, and how does it expand beyond one loop?

The NFS2-3030 supports a maximum of 10 Signaling Line Circuits (SLCs) and a total of 3,180 addressable devices (Page 1) [1].

Each loop accommodates 159 intelligent detectors and 159 monitor/control modules for a 318-point capacity per loop (Page 8) [1].

1. Install an LCM-320 (Loop Control Module) to the chassis to provide the first SLC (Page 11) [1].

2. Mount an LEM-320 (Loop Expander Module) onto the LCM-320 to expand to a second SLC (Page 36) [1].

3. Connect up to five pairs of LCM-320/LEM-320 modules to reach the 10-loop limit (Page 11) [1].

4. Daisy-chain the modules by connecting the ribbon cable from CPU header J7 to the first LCM-320 "Data In" (J1) port (Page 36) [1].

5. Continue the chain from the "Data Out" (J3) port of the first module to the "Data In" (J1) port of the next (Page 36) [1].

6. Assign unique SLC loop numbers using the SW1 rotary switch on each LCM-320 (Page 36) [1].
