SECTION III - SYSTEM INTERCONNECT

3.1

Introduction

Section III contains information relative to KSN 7xx Safety Navigator interconnection diagrams, options
available to the system planner, and specific electrical characteristics of the various interfaces where
applicable. Each paragraph in this section contains the installation wiring diagrams for that section.

For information regarding the compatibility of equipment not listed in this manual, the installing agency
must contact Bendix/King customer service at www.BendixKing.com.

Section III is divided into major sections by interface type or major topic. Each major section describes in
detail the specifications for particular types of interfaces connecting to the KSN 7xx.
