DESCRIPTION
The TraceTek Network Relay Module provides multiple relay
outputs for switching alarm or control devices for the leak detection
system. TT-NRM units are modular and may be configured with 2 to
32 relay outputs. A single TTDM-128 unit communicates with up to
up to 20 NRMs over a single, twisted pair RS-485 cable.

A. Mount DIN rail
Overview of installation procedures for TT-NRM
1. Select a location for installation.
The TT-NRM may be installed in any panel or enclosure
suitable for electronic control devices.
The TT-NRM assembly is powered with line voltage and
switches relay contacts that may be connected to line volt-
age. Select an electrical panel or enclosure considering the
areaclassification(i.e.,non-hazardousorhazardous),the
location(indoorsoroutdoors,exposuretomoistureand/or
dust),andthechemicalenvironment.
Ifambienttemperaturesbelowfreezingareexpected,
install the TT-NRM unit in a heated location or use an
enclosureheater.Ifmoistureisexpected,installadrainin
the enclosure.
2. Size and install DIN rail.
UsethesuppliedDIN35rail.Therailmaybeshortened
if necessary. The width of the TT-NRM assembly is deter-
minedbasedonthenumberofTT-NRM-2ROrelaymodules
used.
A. Mount TT-NRM assembly in enclosure selected for the application.
B. Connect power and relay contact wiring.
C. Connect RS-485 cables and set address.
D. UpdatetheTTDM-128network.

B. Install TT-NRM assembly
1. Attach the TT-NRM components to the DIN rail
The TT-NRM-BASE comes assembled. To remove a
module, pull up on the orange release tab until the mod-
ulereleasesfromtheDINrail.Do not remove modules
while power is on.
ToinstalladditionalTT-NRM-2ROrelaymodules,you
must first remove the End termination module (3)
andtheadjacentDINrailendstop.Slidetheadditional
relay modules into place and ensure they snap on to the
DINrail.ReplacetheEndterminationmoduleandDIN
rail end stop to the right of the last relay module added.
Refer to the TT-NRM Assembly diagram on page 2 for
the proper order of module assembly.
Important:Modulesand/orexternalequipmentmay
be damaged if modules are not installed in the correct
sequence.
2. Attach the RS-485 network connection module to the
DIN rail.
LocatethemoduletotheleftsideoftheNetworkpro-
cessor.PressthemoduledownontotheDINrailtolock
it in place.
Connect the supplied ribbon cable between the Network
processor and the RS-485 connection module.
Usethescrewsprovidedtosecuretheribboncablecon-
nectors.
3. Mount the power supply.
MountthepowersupplyontheDINrailtotheleftofthe
RS-485 network connection module.

D. Connect RS-485 cables and set address
1. Select the RS-485 address for the TT-NRM unit.
Each TT-NRM connected to a TTDM-128 must have a unique
addressintherange1to99.IftwoTT-NRMunitsareas-
signed the same address, communications faults will result.
To ensure you assign an unique address to each TT-NRM unit,
reviewthesystemlayout.Ifalayoutdocumentdoesnotexist,
create one. Assign an unique address to each TT-NRM unit.
Note: TraceTekTTSIMmodulesareconnectedonthesame
RS-485 network and must not have the same address as any
TT-NRM.
2. Set the RS-485 address for the TT-NRM unit.
Useasmallat-bladescrewdrivertorotatetheaddress
switchmarked“x1”tothedesiredaddress.Foranaddress
of50,setthe“x1”to0andthe“x10”to5.

3. Connect RS-485 cables.
Note: Do not make connections to the RS-485 bus while it
is connected to an operating TTDM-128, or damage and/or
alarms could result.
The RS-485 bus allows units with unique addresses to be
daisy-chained together along a common bus. To add a new
unit to the network, simply daisy-chain the RS-485 bus from
the last unit to the new one—or insert the new unit between
twoexistingunitsonthebus.Theorderinwhichunitsare
attached to the RS-485 bus does not matter. There are just
two constraints on the RS-485 network:
• EachTT-NRMmustbeassignedauniqueaddress.
• TheRS-485busmustbeacontinuousstringfromthe
first unit to the last unit in the system.
Note: TheRS-485busoperatesat5V,andequipment
connectedtoitcouldbedamagedbyexposuretohigher
voltages.TakeprecautionstoavoidexposingtheRS-485
wiring to discharge of static electricity or other sources of
high voltage potential; in particular, avoid contact with the
power supply wiring.

Important: Do not connect the shield of the RS-485 cable
to the enclosure or panel grounding terminal. Connect the
shield only to the terminal provided. To avoid the potential
for spurious ground loops, the RS-485 cable shield should
be connected to ground only in the TTDM-128.

E. Update the TTDM-128 Network
TT-NRM units are controlled by a central TTDM-128. The
UpdateNetworkFunctionintheTTDM-128softwaremust
betriggeredinorderfortheTTDM-128torecognizenewor
changedTT-NRMunits.Untilthissoftwarefunctionisrun,
the TTDM-128 will not control new TT-NRM units.
1. Energize all TT-NRMs in the network.
ConrmthattheRS-485networkiscomplete(allTT-
NRMandTTSIMunitsandtheTTDM-128areconnected
totheRS-485bus),andthatthepowertoeachunithas
been turned on.
2. Use the TTDM-128 system software to update the network.
Note:WhentheTTDM-128isrstpowered,itautomati-
callyrunsthe“Update”function.
RuntheTTDM-128“UpdateNetwork”softwarefunction
totriggerittorecognizenewTT-NRMs.TheTTDM-128
UserManual(H56853)describesthissoftwarefunction
in detail.
3. If necessary due to problems or questions, check function
of individual modules.
• VerifythataTT-NRMisfunctioningbyconrmingthat
thepowerLEDisilluminated.
• Checkallconnections.
• CheckthatallTT-NRMmodulesaresecurelyseated

• ConrmthattheTT-NRMnetworkdoesnothaveany
duplicate RS-485 addresses.
• IndividualrelayscanbecheckedusingTTDMSelf-test/
