Circuits and Pathways ‐ Chapter 122010 Edition Wiring tables being replaced with a new system forspecifying wiring redundancy and survivability Includes removal of all of the old class and styletables and designations and the implementation ofnew Classes that will be applicable to any type of firealarm circuit, not just SLCs, IDCs, and NACs as in thepast. The term "pathway" is used instead of circuit toaccount for the use of optical fibers, radio,hardwires, and anything else that may appear in themarketplace.Circuits and Pathways ‐ Chapter 122010 Edition12.1 Application.12.1.1 Paths (interconnections) shall be designatedbased upon the performance characteristicsdefined in this chapter.12.2 Purpose.12.2.1 This chapter describes the performance andsurvivability characteristics for defined classdesignations of signaling paths (interconnections).Circuits and Pathways ‐ Chapter 122010 Edition12.2.2 A path’s (interconnection’s) classdesignation is dependant on the path’s(interconnection’s) capability to continue tooperate during specified fault conditions.12.2.3 The designation of the paths can alsoinclude the performance of the path(interconnection) to survivability from attack byfire.15

Circuits and Pathways ‐ Chapter 122010 Edition12.4.2.1 Pathway Class DesignationsPathways shall be designated as Class A, B, C, D, E, orX, depending on their performance as follows:Class A*. A pathway with a redundant path.Operational capability continues past a single break.Conditions that affect the intended operation of thepath are annunciated.Class B. A pathway without a redundant path.Operational capability stops at a break. Conditionsthat affect the intended operation of the path areannunciated.Circuits and Pathways ‐ Chapter 122010 EditionClass C. One or more pathways whereoperational capability is verified via end‐to‐endcommunication, but the integrity of individualpaths is not monitored. A loss of end‐to‐endcommunication is annunciated.Class D. A pathway that has fail‐safe operation,where no fault is annunciated, but the intendedoperation is performed instead.Circuits and Pathways ‐ Chapter 122010 EditionClass E. A pathway which is not monitored forintegrity.Class X. A pathway with a redundant path.Operational capability continues past a singlebreak or short‐circuit. Conditions that affect theintended operation of the path are annunciated.16
