TraceTek system mapping

Mapping the TraceTek Leak Detection System involves creating a map of the installation and includes references between the distances of sensor wires and point sensors (in feet or meters) and physical references in the installed application in the building.

The system map is used in conjunction with alarm panels that have a leak location option of +/- 1 meter of sensor wire.

1. Start with a working copy of the building floor plan or pipe layout drawing that shows where the sensor wire has been installed. A simple system may have only one circuit, a more complex installation may have many individual circuits.
2. Select any circuit and locate the part of the circuit closest to the monitoring device.
3. Simulate a leak using one of the following methods:

Mapping the TT1000, TT3000 sensor cable

Sensor wire mappingSensor cable mapping TT1000, TT3000

For the TT1000 or TT3000 sensor cable, the TT-MAP-TOOL mapping tool is strongly recommended. Slide the brush onto the sensor cable and leave it in place for at least ten seconds. You can also use a damp cloth, it is important to keep the sensor wire dry at each mapping point before moving on to the next to prevent false readings and/or service alarms. Do not use a tissue, as this can leave damp deposits on the sensor cable. Tests of the TT1100-OHP can be performed with a mapping cap (TT-MAPPING-CAP-PC) at the end of each sensor cable section.

Mapping the TT5000, TT5001 sensor cable

Sensor cable mapping TT5000, TT5001

The mapping process for the TT5000 and TT5001 is similar to the above process, except that leakage can be simulated by bending the sensor wire in a small radius, as shown in the graphic. Remember to hold the "leak" (bend) for at least ten seconds. Do not use hydrocarbons to test/map the TT5000, as this cable is designed for single use. For more information, refer to the corresponding data sheet.

Mapping the TT-MAPPING-CAP terminal

TT-MAPPING-CAP terminal mapping

TT-MAPPING-CAP jest to terminal zakończeniowy symulujący wyciek, używany do sensor cable mapping.

Available in:

  • TT-MAPPING-CAP-PC Used to map TT1000, TT3000, PC connector.
  • TT-MAPPING-CAP-MC Used to map TT500, TT5001, TT7000, MC connector.

For larger systems, TT-MAPPING-CAP should be installed sequentially to each available connector. The mapping terminal simulates a leak at the location where it is installed.

Read the simulated leak

Reading the simulated leakage

On the alarm panel, read the displayed distance for the "leak" location. Save this distance on a working copy of the system drawing. After saving the leak location on the system drawing, go to the location further down in the system and repeat the process. TT-TAG mapping markers and distance readings are required every 4 - 5 meters. Choose locations in corners of the room, in front of air handling units, at structural columns or other "site markers" that are unlikely to change, even if building equipment changes in the future. Note that if a true leak is detected, the operator will use a "system map" to find the physical location of the leak based on the leak location distance reported on the alarm panel.

4. Repeat the above processes for each sensor circuit in the system.


Mapping for two people or for one person

If two people are available, get a set of two-way radios and place one person at the alarm panel. The other person walks around the installed system with a drawing of the system in hand. The panel observer reads and reports the location of the leak simulation. The leak operator can then immediately record the distance on the drawing and move on to the next mapping location.

If the TraceTek system is managed by a TTDM-128, TS-12, AT-APA alarm panel (these panels have an event history), it is quite easy for a single operator to efficiently obtain mapping data. Here's how:

  • First synchronize the time on the panel with the operator's watch.
  • In the TTDM-128 control panel, temporarily enable the auto reset function. (Menu | Leak Configuration | Auto Reset | ON).
  • Simulate leaks with a mapping tool (TT1000, TT3000), by bending the cable (TT5000, TT5001) or by using a mapping terminal. Instead of noting the location of the leak on the working drawing, mark the mapping time of each location. (Try to wait about two minutes between mapping locations).
  • When all relevant locations have been mapped, return to the alarm panel and look at the event history. By going back through the recorded events, you will be able to see the generated leak location and the time each leak was detected. Transcribe the leak locations to the layout drawing.
  • Remember to reset the auto reset function to OFF.

Preparing the final map

Preparation of the final map

Prepared maps are usually prepared using AutoCAD and are a simplified floor plan or pipe diagram showing

  • the basic physical features of the building or system,
  • the approximate location of the installed sensor cable,
  • the location of the control panel and the location readings obtained during the mapping process. Recommended are every 4 - 5 meters.

If possible, use colors. All wire connector locations should be marked to facilitate future wire replacement. The goal is to provide the future operator with enough information to find the leak based on the location information displayed on the alarm panel. The detail should be sufficient to find the leak quickly and unambiguously without littering the finished product too much. Printed maps are often laminated or framed and hung on the wall next to the alarm panel. When more sophisticated building control systems are available, the map is often imported into a graphical user interface for easy online access if needed.
