2 General Introduction

The SensorZone proximity warning system (PWS) is complimentary,

and not a substitute, for existing safe systems and procedures of work.

SensorZone PWS uses advanced RFID technology, an existing and well

established technology.

2.1 System Summary

SensorZone PWS generates a low frequency magnetic eld, referred to as the

exclusion zone, around the antenna. This zone maybe set at between 2m and 10m

radius. The zone is nominally elliptical in shape.

Note: The exclusion zone can be established by a single antenna for small/

medium sized vehicles or with two antenna for larger vehicles. Users should familiarise

themselves with zones in use.

A tag entering the range of

the exclusion zone detects

the magnetic eld and replies

to the base station. The tag

will warn the wearer with

two pulses of vibration.

The base station initiates a

visual and audible warning at

the display and via external

sounders and beacons to personnel in the vicinity.

Every tag detection is recorded in the built in datalogger.
