Complete Bill of Materials
Before beginning installation, confirm there is a plan for the leak
detection system layout, and a complete bill of materials. In
addition to sensing cables, the leak detection bill of materials
should include a TraceTek alarm module, leader and/or jumper
cables, mapping tags (TT-TAG), and various other components,
such as modular branching connectors (TT-MBC-PC).
General Notes—Do’s and Don’ts
Don’t
Do
• Store the sensing cable in its original container in a clean, dry
area prior to installation.
• Drag sensing cable through contaminants (such as pipe dope,
PVC cement, solvents, oil, or dirt).
• Schedule sensing cable installation after major construction
work (which could damage or contaminate the cable) has been
completed.
• Use damaged or contaminated sensing cable.
• Solder or weld near the cable without protecting it from heat,
flux, and splatter.
• Clean the area where sensing cable is to be installed and
remove any debris or other source of contamination.
• Drop tools or sharp or heavy objects onto the cable.
• Pull the sensing cable with excessive force (more than
50 pounds/20 kg).
• Use adhesive tapes or clamping devices to secure the sensing
cable.
• Allow cable connectors to become wet, dirty, or contaminated.

Installation Steps
1. Prepare the area where the sensing cable will be located.
•
Verify that major construction is complete.
•
Clean the area where the cable will be installed, to remove
debris and sources of contamination.
•
Install TraceTek hold-down clips. For TraceTek TT1000
sensing cables, use 1/4" hold-down clips (TT-HDC-1⁄4...).
TT-HDC-1⁄4
or
TT-HDC-1⁄4-200-NA
Clean the floor surface where hold-down clips will be placed,
so adhesive can work properly.
Position hold-down clips so the sensing cable will provide the
desired leak-detection coverage. To best secure the cable,
alternate the direction of the hold-down clips, and install them
at intervals of no greater than 6 feet (2 m) and at every
change in direction.
< 6 ft (2 m)
Important: Let the adhesive dry per the manufacturer’s
recommendation before proceeding with sensing cable
installation.
2. Check each length of sensing cable before installation.
To ensure that each length of sensing cable is intact and free of contamination, follow the “Sensing Cable Test Procedure” on page 5.
Do not use damaged or contaminated sensing cable.

3. Observe proper precautions when handling sensing cables.
Observe the do’s and don’ts printed on page 1 of these instructions;
take care to avoid damaging or contaminating sensing cable.
4. Connect, orient, install, and test each length of sensing cable in sequence
1. Connect a Modular End Termination (TT-MET-PC) to the first
sensing cable length to be installed.

2. Orient sensing cable so end termination will be away from connection to the TraceTek alarm module. Work outward from the
alarm module connection. To help dispense sensing cable on
reels (lengths over 10 feet/3 meters), put the reel on an axle.

3. Install sensing cable in accordance with the engineer’s leak
detection layout plan.
Pull the cable alongside the installed hold-down clips. Leave
6 inches (150 mm) of sensing cable on each end for the connector service loop.
Important: Verify that the adhesive securing the hold-down
clips has dried; liquid adhesive must not contact the cable.
Push sensing cable into the hold-down clips and position the
sensing cable to lay flat on the surface to be monitored.
4. Test each length of sensing cable after installing it and
before attaching it to cable already installed. Confirm that the
sensing cable is clean and intact by following the “Sensing
Cable Test Procedure” on page 5.
5. Connect the sensing cable to the cable string (lengths of
sensing cables connected in series) previously installed.
• Leave a service loop at each connector as shown.
• Mark the connector position on the layout plan.
• Install TraceTek mapping tags (TT-TAG).

Note: As an extra precaution on large installations, periodically test the entire cable string to confirm that all installed
sensing cable is still clean and intact.
Unplug the end termination from the previous length and
connect it to the next length of sensing cable to be installed.
Repeat the installation sequence for each length of cable.

Branching Connectors, Weighted Lengths, and Modular
Jumper Cables—as called for in the system layout. Complete
the sensing circuit.
•
Test the sensing circuit (or portions of it) to confirm that the
sensing cable is clean and intact. Follow the “Sensing Cable
Test Procedure” on page 5.
•
Connect the sensing circuit to the TraceTek alarm module and
activate the system as soon as is practical. Use the module to
monitor for events during the final stages of construction.

6. Take precautions if installation is incomplete at end of work day.
At the end of the work day:
•
Ensure that there are no exposed connectors. Each sensing
cable should be connected to a Modular Leader Cable
(TT-MLC-PC), Modular End Termination (TT-MET-PC),
and/or other sensing cables; check both ends of the cable.
•
Test and record the condition of installed sensing cable following the “Sensing Cable Test Procedure” on page 5.
•
If practical, connect the installed sensing cable to the
TraceTek alarm module. Test the system and put it in operation following the alarm module installation instructions.

Sensing Cable Test Procedure
Method with TraceTek Portable Test Box (PTB)
Testing a string
of cables
1. Ensure the end termination is connected to the sensing
cable. If checking several lengths of sensing cable in series
(a cable string), ensure they are all connected.
2. Connect the PTB to the sensing cable(s) as illustrated.
End termination
3. Verify that the sensing cable is intact; follow the operating
instructions printed inside the lid of the PTB itself. If the cable
string is intact, the PTB measures the system length (length
of TraceTek sensing cable plus the length equivalents of the
weighted lengths and modular branching connectors). If a
cable or connection is broken, the PTB illuminates its LED
indicating “cable break” and displays a “1” in the leftmost
position of its LCD display.

If the cable string is not intact, apply this test procedure to
segments of the system to identify the open connection or
damaged modular length.
4. Check the condition of the sensing cable(s), again following
the PTB operating instructions. If the sensing cables are
clean and free of contamination, the current measured
should be below 10 µA. If the reading exceeds 10 µA, use
the PTB to locate the liquid or contamination and take
appropriate corrective action.
Method with Ohmmeter
Testing a string
of cables
1. Ensure the end termination is connected to the sensing
cable. If checking several lengths of sensing cable in series
(a cable string), ensure they are all connected.
2. Connect a Modular Leader Cable (TT-MLC-PC) to the
sensing cable.

of the leader cable as illustrated.
• Loop 2: Measure the resistance
between the red and green wires of
the leader cable
To yellow
To black
Ohm
meter
To red
To green
The readings should roughly equal a
multiple of the length of sensing cable:
4 times the length of sensing cable (in ft) or
12 times the length of sensing cable (in m)
Example:
4 x 50 ft of cable
= 200 Ω,
12 x 15 m of cable = 180 Ω.
In addition, the resistance of the two loops should be within 5
percent of each other.
If the cable string is not intact, apply this test procedure to
segments of the system to identify the open connection or
damaged modular length.
4. Check the condition of the sensing cable. Measure the resistance between the black and green wires of the leader cable.
If the reading is below 20 MΩ, apply this test procedure to
segments of the system to identify the modular sensing cable
length(s) affected, then locate the liquid or contamination and
take appropriate corrective action.
