User Manual
READ BEFORE USE
Please read these instructions carefully and keep them in a safe place (preferably close to
the TTDM) for future reference. The instructions provided in this booklet must be followed
carefully to ensure proper operation. If the equipment is used in a manner not specied by
the manufacturer, the protection provided by the equipment may be impaired.
PREPARATION
Before operation, follow the installation instructions to ensure that each module is properly
mounted and wired. If these steps have not been taken, refer to the installation documents
provided for each module. To obtain this literature or for technical assistance, contact your
local TraceTek distributor or visit our web site (http://www.tycothermal.com).
IMPORTANT: There should be a “System Map” for each sensor circuit. The system map
should show the sensing cable layout with reference to readily identiable landmarks and
with actual distance measurements every 5 m (16 ft) throughout the system. The map is
normally completed at the time the leak detection system is commissioned. Ensure that a
copy of the system map is kept near the TTDM-128 module. If the TTDM-128 is connected
to a building management system, ensure that a copy of the system map accompanies
the building management system.

Introduction
The TraceTek TTDM-128 Network
The TTDM-128 can directly monitor up to 1500 m (5000 ft) of TraceTek sensor cables,
up to 150 TraceTek point sensors and networks of up to 126 external TraceTek modules
(which can include any combination of TTSIM sensor interface modules, TT-NRM network
relay modules or up to 32 additional TTDM’s operating in slave mode). With a fully
implemented network, it is possible to monitor as much as 190 km (119 miles) of TraceTek
sensor cable and provide as many as 320 discrete relays to handle a wide variety of alarm
and telemetry functions.
NOTE: the maximum number of TTSIMs on a network must be reduced by 4 for each TT-
NRM added.
Each TTDM-128 provides:
▪ An internal Sensor Interface Module (SIM), capable of directly monitoring up to
1500 m (5000 ft) of sensor cable, 150 point sensors, or a combination of both cable
and sensors.
▪ 3 alarm relays, providing status for:
− Leak alarm
− Service required alarm
− System fault alarm
▪ Serial communication to a host computer, control system or building management
system using RS-232 or RS-485 hardware and the MODBUS™ protocol.
▪ Event history log
▪ Optional 4-20 mA output
When liquid is detected on any sensor, the TTDM-128 sounds an alarm, illuminates an
LED, closes relay contacts, and displays the channel number and location of the leak on
an LCD display. Each alarm event (leak, service, fault, etc.) and user action is logged into
the event history le. The event history le shows the type of event as well as the time
and date that the event occurred. This information is available to any host PLC or building
automation system via an RS232 or RS485 serial connection and the MODBUS protocol.
A simple system map (typically an as-built drawing of the sensor installation with reference
measurements) showing where the sensors have been installed is the only eld calibration
requirement.
Each individual sensor circuit detects, locates, and tracks leaks independently from
the other circuits in the leak detection system. There is no loss of sensitivity and no re-
mapping required after an initial leak is detected.
The TTDM-128’s internal SIM has been designed for use with the following TraceTek
sensing cables:
§ TT1000 (water)
§ TT3000 (Acids and Aqueous chemicals)
§ TT5000 (liquid hydrocarbon fuels and oils)
§ TT5001 (organic solvents)
A variety of TraceTek Point sensors, as well as contact closure devices such as oat
switches, can also be used with the TTDM-128.

User Manual
Description of TraceTek Leak Detection System
TRACETEK SENSING CABLES
The TraceTek leak detection system is based on sensing cables that detect liquid at
any point along their length. A variety of TraceTek sensing cables are available to detect
different types of liquids. While multiple types of sensing cables may be used in a single
sensing circuit, if different types of uid are being monitored in the same area it may be
more effective to create multiple circuits, each with dedicated sensor cable of a specic
type.
COMPONENTS OF TRACETEK LOCATING SYSTEM
TraceTek leak detection is a versatile modular system, with interchangeable components
that can be congured in many different ways. For more information on the products and
systems available, consult the appropriate TraceTek product selection guide or your local
TraceTek representative.
A TraceTek locating system provides distributed leak detection and location over long
distances and wide areas. A TraceTek locating circuit consists of a TraceTek locating
module (TTDM-128, TTSIM), sensing cable and/or point sensors, and circuit components
(leader cable, jumper cables, end terminations, weighted lengths, and branching
connectors) with connectors that allow components of the system to plug together.
The weighted length resistor simulates a 4.5 m (15 ft) length of sensing cable. Installed
at the boundary between two areas of sensing cable, the weighted length allows the user
to clearly identify the area where a leak has occurred.
The branching connector enables the sensing cable to be branched. An end
termination completes each branch. At the branching connector, the system rst counts
the sensing cable along the branch (middle connector) to its end termination, before it
continues with the main run. Two built-in 4.5 m (15 ft) weighted-length resistors allow the
user to clearly identify the leg on which a leak has occurred.

which conditions are currently active.
Monitoring
Service
Leak
Fault
Green Yellow Red Red
NOTE: The Service, Leak and Fault LEDs will illuminate if an alarm condition exists on any
SIM. Multiple LEDs may be illuminated simultaneously to indicate multiple types of alarms,
although the alarms could exist on different SIM channels.
MONITORING
This green LED indicates that the TTDM-128 is powered up.
SERVICE
The TTDM-128 is able to give advance warning of potential problems. The yellow Service
LED illuminates to indicate that service is required on one of the sensing cables attached
to the network. Note that the green Monitoring LED remains illuminated; the unit continues
to monitor for leaks during a Service alarm.
LEAK
When liquid is detected, the red Leak LED illuminates. Note that the green LED remains
illuminated; the unit continues to monitor for new leaks on all channels, as well as for
changes to the detected leak.
FAULT
When the TTDM-128 module detects a fault — either a cable fault (break) or an
electronics fault — the red Fault LED illuminates. After a fault on an individual SIM has
been detected, the TTDM-128 module will, in most cases, continue to scan the remaining
SIM units and their associated sensing circuits. However, some fault conditions may
disable multiple channels or even the entire system. The TTDM-128 is unable to detect a
leak on any channel affected by a fault.
IMPORTANT: Always investigate the cause of a Fault condition immediately.
NOTE: For more information on the various TTDM-128 alarm states, see the Event
Response section of the manual on page 29.

Status of Individual SIM channels
The TTDM-128 offers access to detailed real-time status information for each SIM
channel. The status display for an individual SIM channel is accessed from the Current
Event/Status display:
► If in a menu, press ESC one or more times (or press MENU) to return the Current Event/Status
display.
► Use the LEFT or RIGHT arrow keys to select the SIM channel of interest.
► Press the DOWN arrow to access the detailed status information (as shown below) for the
selected channel.

NOTE: Only four lines are displayed at one time. Arrows in the scroll bar indicate if other
entries can be accessed with the up or down arrow keys.
A description of each line on the SIM Status Menu appears below:
SIM Address Channel number for information in current display
ID An alphanumeric label specied by the user (maximum 14
characters).
SIM status SIM Status can contain any of the following text, depending on
the state of that SIM channel:
▪ SIM Normal
▪ Leak {location}
▪ Re-alarm [new location]
▪ Service Required [location]
▪ Leak cleared
▪ Cable break
Test Length Total length of sensing cable attached to the selected SIM.
The test length should be the same as that recorded when
the channel was mapped. If the length is not the same, it
may mean that the system was modied (sensing cable was
removed or added).
NOTE: The Test Length is typically about 1% longer than the
physical or mapped length for the channel; this is normal.

Location The current location — or electrical center — of the leak (or
cause of a Service alarm). If the SIM status is Normal, the
Location entry is blank.
Sense Cur This current (measured in µA) indicates the condition of the
sensing cable. If a leak is detected in the channel, this rises to
270 µA or more (depending on the type of TTSIM). In a clean,
leak-free sensing circuit, the current should be 5 µA or less. If
the current rises above 20 µA, service is recommended, as it
may indicate the presence of contamination.
Serv Alert >= This setting controls Service Required Alarms. If Sense Cur is
greater than this value, the TTDM signals a Service Alarm.
Sense Res This is the resistance measured between the sensing wires.
For a clean, leak-free sensing circuit, this resistance is more
than 20000 kΩ. If liquid is detected, it will drop to less than 30
kΩ. If the resistance is changing, it may indicate an event in
progress.
Leak Alarm <= This setting controls Leak Alarms. If Sense Res drops below
the threshold level, the TTDM signals a Leak Alarm.
R-G Res,
Y-B Res
These are the resistances of the Red-Green and Yellow-Black
loops in the TraceTek sensing circuit. If these values are
signicantly different from each other, the TTDM will signal a
Loop Imbalance alarm, indicating damage to a sensing cable
or connector.
SI Version This indicates the software version operating in the SIM
microprocessor.
SI Comm This indicates the success rate (in percent) for
communications between the TTDM-128 and the SIM channel
selected. A value below 90% may indicate a faulty connection
or damaged RS-485 cable.
Add Regions/Relays This menu item accesses a submenu that lets the user divide
a length of sensing cable into as many as 10 smaller logical
sections (regions) and assign relays to those regions. Dividing
a length of cable into regions can help the user identify the
location of an alarm condition. By assigning relays to regions,
it is also possible to create a wide range of alarm actions
depending on the region and sensor condition. See Setting Up
Regions, page 21.

Modifying Settings for Individual SIM Channels
To change the alphanumeric tag for the selected SIM channel:
► Select the appropriate SIM channel as described previously in this section.
► Use the DOWN arrow key to select ID, then press ENTER.
► Use the LEFT and RIGHT arrows to select a character position to modify.
Tip: Use the RESET key to “tab” between Letters, Numbers, and blank.
► Use the UP and DOWN arrows to cycle through all available characters until the desired
character is displayed. There are numerous punctuation, currency, Katakana, and non-
English alphabetical characters available. Going “up” or “down” cycles through all available
characters.
► Press ENTER once the label has been set up as desired.
To change the length units for the selected SIM channel:
► Select the appropriate SIM channel as described previously in this section.
► Use the DOWN arrow key to select Test Length, then press ENTER.
► Use the DOWN arrow key to select the desired units, then press ENTER.
CHOOSING APPROPRIATE LEAK ALARM AND SERVICE REQUIRED LEVELS.
Leak sensitivity and Service Required levels should be based on the type of liquid being
detected and the environment in which the sensing cable is installed.
▪ Normal (default) for most applications.
▪ High for de-ionized water.
▪ Low for particular active or exposed applications.
▪ TT500x for systems using hydrocarbon-sensing cable (TT5000, TT5001) to monitor
doublewall pipes and tanks.
▪ Never (only available for Service Required setting) to disable the Service Alarm.
NOTE: Password is required to change leak and service sensitivity settings.
To change the leak alarm sensitivity:
► Select the appropriate SIM channel as described previously.
► Use the DOWN arrow key to select Leak Alarm <=, then press ENTER. If a password is
requested, input the value 00010 then press ENTER.
► Use the UP/DOWN arrow keys to choose a sensitivity level (Normal, High, Low or TT500X),
then press ENTER.
To change the Service Required setting:
► Select the appropriate SIM channel as described previously.
► Use the UP/DOWN arrow keys to select Serv Alert >=, then press ENTER. If a password is
requested, input the value 00010 then press ENTER.
► Use the DOWN arrow key to choose a Service Alert level (Normal, High, Low, TT500X, or
Never).
► Press ENTER.
