●Doplacenodesontheinteriorofthedetectionareawalls.Whentheareatobesensedis

●Dousebatterypacksduringconfigurationandtesting.Itisrecommendedtotestanareausing

●Dosetsensitivitythresholdsashighaspossible.Toavoidfalsealarms,trysettingthethreshold
atahighvalueuponinstallation.Testthesystem,andifit’snotsensitiveenough,decreasethe

workyourwaytolowervaluestoavoidfalsetriggering.
DON’T:
●Don’tinstallnodesonthegroundoragainstmetal.Thiswillseverelylimitsensing
performanceandcommunicationrangeofyourTMDsystem.Placenodesatleast.5metersfrom
thegroundanddonotmounttometalsurfaces.
●Don’tinstallthesensingsystemaroundtreesorfoliage.Movingbranchesandleavescancause
falsetriggeringiftheyarewithinornearthenetworkarea.Thisisespeciallytruewhentheareais
open(notenclosedbydensewallslikebrick,concrete,masonry).
●Don’tinstallnodestoohighfromtheground.Placingnodestoohighwillraisethesensing
