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 aect 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 conrmation.

Pole Mounted Survey Tool (1 per kit)
This part of the survey equipment when
used in conjunction with the Signal
Surveyor Unit, identies 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.
