INTRODUCTION
Congratulations on purchasing your Xandem Tomographic Motion Detection (TMD) kit! This document
provides detailed technical information and will guide you through the process of installing and
configuring your system.
A Xandem TMD system is made up of two kinds of devices. The
nodes
are the devices that surround the
area where motion is to be sensed. These nodes are not actually sensors because each one cannot sense
anything by itself they only work in tandem with other nodes. The more nodes you have, the more area
you can cover per system.
The
processing unit (PU)
is the second kind of device which acts as a gateway for the motion detection
signal. It has two normallyclosed contacts for motion and trouble triggering that can be used to easily
integrate the TMD kit with other systems, as shown in Figure 1. When the TMD system detects motion
within the area surrounded by nodes, or when a trouble with the system is detected, a normallyclosed
relay on the processing unit is opened. This is a standard way in which most security and automation
panel equipment is triggered.
