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.

Pole Mounted Survey Tool (1 per kit)

This part of the survey equipment when

used in conjunction with the Signal

Surveyor Unit, identies accurate signal

strength information between the two

points. Since wireless devices and RCCs both

communicate using the same 868MHz

wireless protocol, the process for device to

RCC/RLM surveys is the same as RCC to

Hub/RCC surveys.

Signal Surveyor (1 per kit)

This part of the survey equipment is used to

communicate with the Device Survey Tool.

This unit will be located in the position of

the proposed Hub, RCC or RLM.

Device Survey Poles (4 per Kit)

The survey poles are used for connection

into the Device Survey Tool. This allows

results to be taken from device locations

which are out of reach.

Note: to ensure optimum surveying accuracy,

it is recommended that minimum two polls

are used with the Survey Tool.

Signal Surveyor mains charger

(provided separately)

The mains charger is used for connection

into the Signal Surveyor units for

re-charging the devices on board battery.

Once switched on, the Signal Surveyor’s display will show the current background interference

level. To achieve the maximum signal distance the background level should be as low as

possible. This level is shown between 000 and 100. If the background levels are high, try

repositioning the unit. Then turn o and back on again. This will re-show the background level

for the new position.

Device Survey Tool Features

Device Survey Tool Battery Replacement

The device Survey Tool requires 4 x AA (LR6 Alkaline 1.5V) batteries. Please ensure batteries are

installed in the correct polarity as shown above.

Signal Surveyor Battery Replacement

The Signal Surveyor’s mains charger can be left connected if necessary, during the survey

process. The rated mains supply voltage is between 90-264Vac 47-63Hz 0.35A max.

Authorised chargers limit output current to 1.0A

Should the internal battery require replacement, correct polarity must be observed as marked

on the battery (NP4-6 6V, 4.0Ah) red wire = positive, black wire = negative.

Whether undertaking a Fusion RLM or FireCell survey, a level of 24dB or above is required

as a pass result.

With the Device Survey Tool switched on, depress the rear switch to initiate a signal. After a few

seconds results will be displayed and a high pass or a at fail tone will be heard.

LED signal indication is also shown on the device, a Green LED indicates a Pass and the Yellow

LED indicates a Fail.

Note; the battery icons shown above (bottom right of

display), will alternate with a test number also shown.

The background levels are taken into account prior to displaying the events on the units. If the

required device position fails to pass the test then a further RLM/RCC position will need to be

found closer to the device and the survey repeated. Every device position should be recorded

along with the received signal levels.
