TraceTek Leak Detection and Location Module - California ...

Installation Instructions for TTDM Alarm and Locating Module
Connecting the Sensing Cable Start-Up and System Testing
Prepare sensing cable.
Ensure that the sensing cable has been installed and tested in
accordance with the instructions provided with the cable.
Make connections.
• Confirm that power to the unit has been shut off.
• Open the enclosure door.
• Feed the end of the TraceTek Modular Leader Cable (or Jumper
Cable) through the adapter/bushing.
• Connect the four color-coded wires to the Sensor Interface plug.
Important: Observe the color coding. If wires are not connected
to the proper terminals, the leak detection system cannot operate
properly.
• Insert the sensing cable (SI) plug into the SI socket (item 20 on
the product illustration on the first page).
Install zener barrier, if applicable.
When sensing cable will be located in Class I, Division 1 locations,
approval agencies require that the sensing cable be protected
with a zener barrier between the sensing cable and the
TTDM module. A zener barrier may also be used to provide
lightning protection for the module when the sensing cable may
be exposed to electrical discharges. Contact Raychem to select
the proper zener barrier.
When installing a zener barrier, wire it in accordance with the
instructions provided with the kit.

Power up the system.
After connections are complete, supply power to the unit. The
unit will go through a series of self-tests, and then display the
system status. If the sensing circuit is complete and free of leaks
or other problems, the green Monitoring LED only will illuminate,
and the LCD display will appear as follows:
System Normal

If this is not the case, you can find additional information in the
TTDM Operation and Maintenance Manual supplied with the
module.
Commissioning
Your system should be commissioned by an authorized
TraceTek representative. The system map is a crucial part of a
TraceTek locating system. The TTDM will give the point along
the sensing cable at which liquid has been detected; the map is
essential to show its physical location.
Important: Store hardware and documentation supplied with
the TTDM in a secure place for later use (commissioning,
connecting interfaces, operating).
