Introduction - EMS FireCell FC-868-SE2 User Manual

Introduction

This manual provides a guide to using the FireCell 868MHz wireless survey kit.
The wireless survey kit should be used to determine the FireCell equipment requirements for
the site, to ensure that full wireless site coverage for the areas concerned is achieved, with the
required signal strengths for reliable communication.
Each site will have a level of background noise, that may a ect the signals on site. Under
EN54-25 (Fire detection and re alarm systems components using radio links). The minimum
signal headroom must be checked, to ensure reliable communication. This is essential to
ensure immunity against site attenuation, caused by environmental changes and other
electrical equipment.
The survey will create the foot print for the installed system, specifying the nal positions for
the devices and wireless infrastructure.
The FireCell wireless survey kit has been designed so that it can survey both FireCell and
Fusion Radio Loop Module (RLM) systems.
All wireless communication is bi-directional and utilises the 868MHz frequency.
It is recommended that the survey results are recorded for future reference. The survey kit
automatically calculates the required headroom (signal level above background interference),
then displays the results. The results are displayed together with Pass or Fail con rmation.
