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

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

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