System ID - System Segregation
The system ID provides a mechanism for segregation of two or more systems that are in close physical proximity,
as summarised previously.
System Commissioning and DLP Support
Commissioning of Nexus® RF systems by a Thomas & Betts Nexus technician and support throughout a standard
12 month defects liability period (DLP) are included in system quotations. This service is usually shown as a
separate quotation line and should be ordered at the time of system purchase or no later than completion of
installation.
Thomas&BettscommissioningandDLPsupportfurthersimpliesthetaskoftheinstallingcontractorandensures
thattheendusertakesdeliveryofasystemthatperformstothebestofitsability.Thecontractorisresponsiblefor
providingsite-specicinformation,aswouldbethecaseforpreparationofastandardemergencylightinglogbook.
Guidance on the requirements will be made available by Thomas & Betts.
Commissioningmaybeundertakenremotefromthesite,particularlyinthecaseofruralorremotelocations,in
which case it is a requirement that remote access is available through a reliable broadband internet connection;
Thomas & Betts will provide a wireless broadband modem for the duration of the DLP and may call on the
customer’s on-site maintenance staff to connect the modem or reset from time to time if required. Alternatively,
remote access may be made available by the end user via a WAN or VPN connection to the site.
DLP support includes testing at 6 and 12 month intervals following completion of commissioning and repairs which
may be required following testing.
The Four Steps to a Nexus RF System
Nexus RF System Design
Step 1 - Review the site plans and determine the
tting requirements
It is important that the site plans are reviewed and
thetotalttingnumbersandtypesareestablishedas
earlyaspossible.Atthispointanynon-standardtting
requirementsneedtobehighlightedtothekeyaccount
manager.
Step 2 - Planning the number and location of the
Routers
The number of Routers and their optimal locations
dependonthenumberofttingswithinthebuildingand
theconcentrationofthesettingswithincertainareas.
The rules for determining the number of Routers and
Figure 1 - Shows a typical ofce building with 3 Routers
optimally located to pick up the site’s 270 ttings. The shaded
areas are representative of how it is envisaged the mesh
networks will form.

their positioning are as follows:
• TheloadonaRoutershouldbedesignedatamaximumof90ttings.
• Tominimisehopcountstothettingsbeingserved,thecontrollershouldbelocatedascentraltothesettings
as possible.
Step 3 - Designing the IP Backbone
TheAreaControllersandAreaControllerRoutersneedtobeinterconnectedbyanIPnetwork.Dependingonthe
site it may be possible to utilise an existing IP infrastructure, on others there will be a need to design and install a
dedicatednetwork.IfanexistingIPinfrastructureistobeutilisedthenyouwillneedtoconsultthenetworkmanager
withregardstoaccesspointsandIPaddressesforthenetwork.Allowancesshouldbeprovidedonthenetworkfor
connection of a PC if required and a remote access 3G device.
TheNexusRFspecialistcanassistbyprovidingasystemnetworkdiagramifrequired.
Step 4 – Allocation of tting SPU ID’s
Itisimportantthateveryttingwithinthesystemisuniquelydened.TheuniqueSPUIDnumber(withinthe1-
65,000range)assignedtoeachttingprovidesthisfunction.Inthesamplesitedetailedinstep2onepossible
logicalallocationofSPUIDnumberscouldbeasfollows:

4
Level SPU ID Range
Ground Level 1 - 30
Level 1 100 - 129
Level 2 200 - 229
Basement 1 300 - 359
Basement 2 400 - 459
Basement 3 500 - 559
ThistypeofallocationallowseasycrossreferencingofaSPUIDtoitsassociatedoorandalsoallowsplentyof
rangeforadditionalttingsifandwhenrequired.ToformalisetheprocessofallocatingSPUID’stottingsitis
essentialthatthesiteplansaremarkeduptoreecttheallocatedSPUID’s.Alsoduringtheinstallationphaseit
isnecessarytocapturespecicinformationabouteachofthettingsincludingSPUID,MACaddress,location
details and database/circuit details. This information is required in electronic format for system commissioning; a
commissioningspreadsheettemplatelewillbeprovidedtoyoubytheassignedNexusRFspecialist,allrelevant
data must be entered into this spreadsheet.

Nexus RF System Installation
Step 1 - Fitting Installation
Duringthettinginstallationprocessthefollowingstepsneedtobe
performed:
• Installeachttingtypeaccordingtothesuppliedinstallation
brochure.
• LabeleachttingwithaSPUIDlabel.
• CollecttheMACaddressofeachtting.
EveryluminaireisttedwithaMACaddresslabelwithapeeloffsection,refertogure2.Thepeeloffsection
includestheMACaddressnumberplusthisnumberrepresentedasabarcode.ThisMACaddressisaunique
hardwareidentierandisofabsoluteimportanceduringthecommissioningphase.Itisintendedthatpriortotting
installation hard copies of the commissioning spreadsheet compiled in step 4 of the design phase be printed. The
peeloffsectionoftheMACaddresslabelcanthenbeattachedtothishardcopyofthecommissioningspreadsheet
nexttothecorrectSPUID.
Step 2 - IP Backbone Installation
InstalltheIPbackboneaspertherecommendeddesign.ARJ45patchpointandGPOneedtobeprovidedin
close proximity to the intended mounting location of each of the Controllers. The 3G remote access device will also
requireanadditionalGPO.
Step 3 - Router Installation
EachoftheRoutersinthesystemrequirecongurationpriortheirdeliverytosite,thisworkisusuallyundertaken
bytheNexusRFspecialist.Congurationincludesloadinganyrmwareupdates,settingtheRouterIDandloading
eachRouter’sIPaddress.TypicallytheseRoutersarenotdeliveredtositeuntiltheendofthettinginstallation
process, ie: the site is approaching the commissioning phase. Installation of a Router involves mounting it on the
wallviaitsmountingbracket,supplyingpowerandconnectingitintothenetworkviathesuppliednetworkpatch
lead.
Nexus RF System Commissioning
A site is ready to be commissioned when the following criteria are met:
• 90%ofttingshavebeeninstalledandhaveconstantpower.
• IPbackbonehasbeeninstalledandveried.
• Routers have been installed.
• Markedupplansandcommissioningspreadsheetsareavailableandluminaireslabelledwiththeirallocated
SPUID’s.
AllcommissioningoftheRoutersandttingswillbeperformedbytheNexusRFspecialistbasedonthe
networkdesignandthettinginformationcontainedinthecommissioningspreadsheet.Uponcompletionofthe
commissioningprocesstheNexusRFspecialistwilltestthesystemandprovidetestresultandttinglocation

reportstoyouasproofofsystemoperation.IfanyttingissuesariseduringthisphasetheNexusRFspecialistwill
assist in their resolution.
Defects Liability Period
OncompletionofthecommissioningortestingphasetheDLPphasecommences.Duringthe1yearDLP
Thomas & Betts monitor the site operation periodically to ensure reliable system operation. At 6 and 12 month
intervalssystemtestingisperformedandanysystemissuesidentiedwillbeaddressedbyThomas&Betts.Test
resultreportswillbesuppliedtoyouforthese6and12monthlytests.Ongoingsystemtestingandsupportservices
are available in the form of service agreements; details are available from your Thomas & Betts representative.
