IMPORTANT NOTES
• The TTC-1 module is designed for use with TraceTek sensing
cables and probes only. A TTC-1 based system will detect and
alarm on all fluid leaks detected by the TraceTek cable as per
the appropriate cable data sheet.
• Transient spills and contamination may also activate the
system. Users should consider this operational function when
determining the suitability of the TraceTek system for specific
applications.
• The system has not been designed for repetitive cycling.
• Always connect the Leak Detection relay to an annunciation
device (for example the nVent RAYCHEM TraceTek TTE-XAL
External Loud Alarm) so that an operator is notified and can
verify proper operation if automatic equipment is connected.
• Maintenance personnel should examine the sensing cable for
cleanliness and verify proper operation of the TTC-1 module at
least every six (6) months.

DESCRIPTION
The nVent RAYCHEM TraceTek TTC-1 sensing module is used with
TraceTek sensing cables to detect liquid leaks. The module provides
visual indication when a leak or cable break has occurred and has
relay contacts to connect the TTC-1 to external devices for remote
monitoring and control.
ELECTRICAL CODES
Installation must be done in accordance with national and local
codes and regulations that apply. The TTC-1 must be installed in
ordinary areas only.
