Installation Wiring a Signaling Line Circuit (SLC)50 AFP-200 PN 15511:H2 10/14/2002Figure 30 ISO-X Module Terminal ConnectionsIsolating a Branch of a Two-wire SLCA short circuit on the SLC Style 4 branch (connected to ISO-X terminals 3 and 4)causes the branch to be disconnected and isolated from the remainder of the SLC. Thisprevents a communication problem with all other addressable devices on the branches(labeled “Continuation of the SLC” in Figure 31) and all addressable devices on theisolated branch will report a trouble condition at the CPU.Figure 31 Wiring an ISO-X (Style 4)2.9.10 Wiring an IDC with Monitor ModulesOverview of Monitor ModulesThe FMM-1, FZM-1, and FMM-1 Monitor Modules are addressable modules thatmonitor conventional contact-type, alarm, supervisory, security, alert, or troubleinitiating devices. You can wire a supervised monitor-module circuit as an NFPA StyleB or Style D Initiating Device Circuit (refer to Figure 34 and Figure 35 for Style B;refer to Figure 36 and Figure 37 for Style D).Refer to 2.9.6 “Setting an SLC Address for a Module” for instructions on addressingthe modules.• FMM-1. Use for wiring Style B and Style D IDCs.• FZM-1. The FZM-1 Monitor Module is an addressable module used to monitor asingle Initiating Device Circuit of smoke detectors. Use FZM-1 modules tomonitor conventional, two-wire smoke detectors.
