GENERAL NOTES: DO'S AND DON'TS:
Do:
• Store the cable in its original container in a clean, dry area until ready to install.
• Clean the pipe surface where the cable will be installed.
• Schedule the sensor cable installation as late as possible in the construction schedule to avoid risk
of damage or contamination by other contractors or construction tasks.
• Remove cable from the pipe if any thread cutting, welding, soldering or similar pipe fitting work will
be performed.

Description
These Instructions explain the proper procedures for installing and
testing TraceTek TT1100-OHP sensing cables. TT1100-OHP sensing
cables are primarily intended for use on overhead piping to detect a water
leak originating from a small pin hole or crack in the pipe. The wicking
action of the absorptive synthetic fiber outerbraid on the TT1100-OHP
cable can catch and hold a small drip or trickle of water– to ensure
sufficient wetted length to generate a leak alarm. TT1100-OHP can also
be used on floors, in drip pans, in sumps and trenches and similar flat
surface applications, however TT1000 standard water detection cable may
be better suited to flat surfaces.
important notes
When used to monitor suspended or rack mounted pipe, TT1100-OHP
sensing cables must be attached to the pipe at the lowest point where
any water leak is most likely to drip from the pipe system. This will be the
6 o'clock position on horizontal piping but other mounting locations and
techniques may be necessary if site conditions are unusual. In particular,
special consideration should be given to pipe supports, couplings, "T's",
valves and other fittings. It is the responsibility of the installer to position
the cable such that any leak will drip onto the cable.
The sensor cable cannot stop a leak. In some installations the materials
or structures beneath the pipe system may be so critical or valuable,
that a drip tray system should be considered in addition to the sensor
cable installation. TT1100-OHP is intended to alert the user that a pipe or
system is leaking but it cannot prevent collateral damage if the leak is not
contained and repaired immediately.

Tie wraps Supplied by installer and sized to go around the pipe
and sensor cable. Base quantity on one tie wrap per
foot (0.3 m) for horizontal run with extra wraps at
fittings.
Rags and appropriate Use to wipe and clean bottom and side surfaces of
cleaner pipe prior to cable installation.

Don't:
• Drag the cable through water, paint, solvents, oil or other contaminants.
• Install damaged or contaminated sensing cable.
• Allow the cable to become wet or contaminated after installation.
• Exceed the maximum pulling force of 100 kg (220 lb).
• Use the cable as a rope for lifting or securing any object.
• Allow tools or heavy objects to fall on cable.
• Exceed 3300 ft (1000 m) sensor cable circuit length
