1.8 Comander System Architecture Examples
1.8.1 Single Comander System
In its simplest implementation, a Comander unit can be used as a standalone intruder
detection and alarm system. In this example, a square perimeter with two gates is
divided into 16 zones, with the fence in each zone protected by an Interceptor cable. It
is not a very realistic example, but serves as a useful illustration of the basic principles
of Comander-based detection systems.

1.8.1.1 Interceptor and Contact Inputs
The Interceptor cables are connected on the fence to Junction Boxes, and the
Interceptor signals are carried by Feeder Cables back to the Comander Marshalling
Box, which is located along with the Rack in a control room. Each Junction Box
contains a microswitch which is connected separately as a Monitored Contact circuit,
ensuring intrusions into the Junction Box can be detected as a Tamper condition.
Note that each Interceptor cable must be terminated in an End-of-Line Termination
