2.2 Wiring

2.2.1 Junction box (for FELCOM 16/19)

Use the junction box IC-315 to connect the SSAS alert unit to the FELCOM 16, or the
junction box IC-318 to connect the SSAS alert unit to the FELCOM 19. Unfasten four
screws to remove the cover to connect cables to terminal board. For detailed wiring
information see the interconnection diagram.
For connecting the SSAS alert unit IC-307, use the JIS cable TTYCS-4 (or equivalent, see
next page for sectional view of this cable) or the CO-SPEVV-SB-C 0.2x5P. When using the
CO-SPEVV-SB-C 0.2x5P cable, replace the cable clamp with the cable clamp
16-018-6008-1, supplied with the junction box. For connecting the communication unit
IC-216, use cable 16S0344.
