5. Complete the system.
• Install other TraceTek components (such as Modular
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 detailed on page 6.
• Install heat-shrinkable tubes over all mated male/female
(pin/socket) connections
— Move the heat-shrinkable tube along the sensing cable
until it is centered over the mated connection.
— Using a heat gun or Ultratorch, shrink the tube over the
connection. Begin in the center and shrink toward each
end until tube fully conforms to the shape of the
connection.
Note: If a heat-shrinkable tube must be removed (for
example, for cable testing), refer to Oversleeve Removal
Instructions (H54258).
• 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-MC), Modular End Termination (TT-MET-MC), 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 6.
• 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.
At the beginning of the next work day:
• Check that the installed sensing cable is clean and intact
following the Sensing Cable Test Procedure. Compare the
results with those obtained at the end of the previous work
day. If necessary, investigate and correct problems before
proceeding.
