2.9 Wiring a Signaling Line Circuit (SLC)

2.9.1 Overview of SLC Wiring

Communication between the control panel and intelligent and addressable initiating, monitor, and control devices takes place through a Signaling Line Circuit (SLC). You can wire an SLC to meet the requirements of NFPA Style 4, Style 6, or Style 7 circuits.

This section covers the topics outlined in Table 9:
