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:
