Common Setup Procedures
All modules, cables and sensors should be installed in accordance with their installation
instructions prior to performing the setup procedures.
BASIC TTDM-128 SETUP (FOR ALL CONFIGURATIONS)
►Power up the TraceTek system. Wait while the TTDM completes its self test and network

►Press MENU to return to the Current Event/Status display
SETTING TTSIM ADDRESSES ON NETWORK SYSTEMS
If your system includes TTSIM modules, their network addresses must be set to unique
values typically in the range from 2 to 127 (address 1 is the default address of the
TTDM’s internal Sensor Interface board). If TT-NRM network relay modules are installed,
the TTSIM addresses must be different than any TT-NRM addresses. (Note: TT-NRM

User Manual
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 127 external TraceTek modules
(which can include any combination of TTSIM sensor interface modules, up to 32
additional TTDM’s operating in slave mode or up to 10 TT-NRM network relay modules
or). 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.
Each TTDM-128 provides:
▪an internal Sensor Interface Module (SIM), capable of directly monitoring up to 1500 m
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 or other events) is logged into an
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.

H56874 4/03 www.tycothermal.com [phone]
PREPARATION
Before operation, follow the installation instructions to ensure that each module is
properly:
§ Mounted
§ Powered
§ Connected to a TraceTek sensing cable or point contact closure device with a
TraceTek jumper or leader cable
§ Interconnected with the other leak detection modules using RS-485
wiring
If these steps have not been taken, refer to the installation documents provided
for each module. This literature can be obtained from the TraceTek 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 readily identiable landmarks and
with actual distance measurements every 5m (15 feet) 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.
Notes
§ Throughout this manual, the examples shown use distances in
meters.
§ Later versions of software may provide new features and change certain other
details. This manual documents UI software version 4.

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. Four types 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 specic
type.
COMPONENTS OF TRACETEK LOCATING SYSTEM
TraceTek leak detection is a versatile modular system, with interchangeable components
that can be congured in many different ways. For more information on the products and
systems available, consult the appropriate TraceTek product selection guide: Raychem
document H53874 for water detection in commercial buildings, H55869 for industrial and
environmental applications.
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 15-ft (5-m) 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 15-ft (5-m) weighted-length resistors allow the

An important part of a TraceTek locating system is the system map: an as-built drawing
with distance references along the sensing cable. Thus, in case of an alarm, the location
of the event can be determined quickly. The copy of the map should be kept near the
TTDM.

The icons represent the four states of the TTDM-128 leak detection network. The LEDs
indicate which states 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-PLUS is powered up and monitoring at least one
sensor circuit.
SERVICE
The TTDM-PLUS 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-PLUS 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-PLUS 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-PLUS is unable to
detect a leak on any channels 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 Alarms section
of the manual on page 35.
