SLC Addressable Device Wiring Diagrams
Refer to the instruction sheets packed with each device.
Detectors and modules may be wired together according to several NFPA defined wiring
styles. The wiring style that is appropriate for your installation should be determined from the
relevant building codes and the local Authority Having Jurisdiction.
Style 4 wiring permits branching of circuit connections. The control equipment supervises
modules because they are active and must respond periodically to the control panel’s poll.
