When should I use a probe instead of water sensing
cable? |
:: |
Probe allows
the monitoring of leaks in areas where sensing cables
would be difficult to install, either because of
the harsh operating environment or if the area is
wet or damp like the base of a lift pit or in plant
areas. |
|
:: |
What
sort of layout do I need for a computer room /
Comms room? |
:: |
A
typical layout would be to cover the inner
perimeter of the room in front of any air conditioning
units, covering the main central area of the floor
is optional depending if there are any water services
in that area.

I
have a TTDM monitored TT1000. Will I need a separate
panel to cover the extension to the new Comms room? |
:: |
No. Each
TTDM panel can monitor upto 1500 metres of sensing
cable or a mixture of sensing cables and probes.
We can cover the new area as an extension of the
existing room by adding a jumper cable and weighted
length to the end of the circuit. We can also add
a TTSIM (slave controller) so that the Comms room
is monitored as a new circuit on the same master
TTDM panel. |

In
a recent Health and Safety report our elevator
pit was considered a weak spot due to water ingress
and the potential of leaks from the hydraulic lift
equipment |
:: |
Installing a
AT-SZA or AT-DIM panel connected to a AquiTron™ AT-OPSEN
optical sensor would detect both water and hydraulic
oil. The AT-OPSEN has an IP67 rating for this type
of environment. |
|
:: |
As
a government agency we are required to meet the
highest standard of vigilance re refrigerant gas.
What would the most effective method of detecting
any gas leaks be? |
:: |
A
refrigerant Leak Monitor AT-RLM can monitor
upto 16 individual sensors. The unit is able to
detect elements of refrigerant gas in the air from
1ppm to 1200ppm. Alarm levels can be set to give
early indication meeting the HSE minimum exposure
limits and the BS and EN standards |
|
:: |
What
is the expected life of the TraceTek cables? |
:: |
Based on
accelerated aging, TraceTek sensing cables have an
expected life well above 20 years. From a practical
consideration mechanical damage chemical exposure
(tripping the TT5000 series, or fouling TT1000 or
TT3000) are most likely to determine the life under
use conditions. |
|
:: |
How
can we test the TraceTek TT5000 cable to ensure
that is working? |
:: |
You
can bend the cable to stimulate a solvent or
fuel leak. Bending the cable simulates the swelling
of the conductive inner jacket that occurs in the
cable when it comes in contact with solvent/fuels.
When the cable is returned to its normal shape
(unbent) the system will return to normal.

|
:: |
Do
you repair TraceTek cables if the customer is having
a continuity problem? |
:: |
No,
if you are having a continuity problem when
you first install the system, we will test the
cable and replace it at no charge, but if the customer
damages the cable, it is their responsibility. |
|
:: |
If
an engineer asks "Is there a difference between
TT1000 and TT3000?" |
:: |
Obviously,
TT1000 and TT3000 have the same basic construction.
However, TT3000 is the industrial grade product that
we have tested and rated for chemical exposure. TT1000
has easy to use plastic connectors, and is intended
for use in commercial buildings. TT3000 is available
in modular lengths with factory-installed, low profile
metal connectors, and comes with heat shrinkable
tubing to cover the connectors (which will provide
extra protection that the plastic connectors wouldn’t).
TT3000 is also available on bulk reels for installation
in double containment piping; connectors are installed
at access point (after cable installation) using
TraceTek connector kit. |
|
:: |
How
do you clean a TraceTek cable? |
:: |
TT1000 and
TT3000 can be cleaned on the top rack of the dishwasher
(join the male + female connectors together, ensuring
that on the TT1000 cable the orange "slip fit" ‘O’ ring
is still fitted as these often fall out in normal
handling, cover the connectors with plastic bags
as a final precaution to stop water getting in).
TT500 and TT5000 series cables cannot be cleaned
of oil. |
|
:: |
What
is the classification for TraceTek cables? (TT5000,
TT3000) |
:: |
TraceTek cables
are designed for C1D1 areas and are intrinsically
safe |
|
:: |
In
a sludge line, can TraceTek sensing cable be spliced? |
:: |
TT5000 series
cables can be spliced in the field using TraceTek
connector kits (installer must be trained). However,
we sell sensing cables with factory installed connectors
in modular 0.3, 1.5, 3, 4.5, 7.5, 15, & 30 metre
lengths. Except for installations in double contained
piping, it is usually better to use the modular cables
with pre-installed connectors. Replace the whole
section, disconnecting at each end and reconnecting
the new length. |
|
:: |
I
want to use the TT1000 series cable to detect a
water/propylene glycol mixture? (60/40 or 50/50
mixture) Will the cable detect the leak? Will the
leak damage the cable? |
:: |
As
long as the liquid is conductive (and any water
based solution will be) the TT1000 cable will detect
the leak with no problem. Both TT1000 and TT3000
use fluoropolymer materials and so there will be
no negatively affected by glycols of any strength. |
|
:: |
Can
the TraceTek TT5000 cable be re-used after it detects
a leak? |
:: |
No,
you must replace the section that detected
the leak. |
|
:: |
When
I hit the test button on my TTB-MA module, all
I get is a light signal, but I am not getting any
alarm? |
:: |
The
system is already in an alarm mode, or has
a cable continuity problem. After the system goes
into alarm and the reset button is pressed, the
buzzer will not go off until the fault is cleared.
The buzzer will only go off if the test button
is pressed and the cable is intact and not sensing
a leak that has already been acknowledged. |
|
:: |
What is the wire that runs through the middle of
the TT1000 and TT3000? |
:: |
The
wire inside is not part of the TraceTek detection
circuit. It is a backbone for the sensor only.
[some what proprietary]. |
|
:: |
What
can you use to connect two series lengths of TraceTek
cable to wire through the wet areas? |
:: |
Use
jumper cables, and we recommend using a weighted
length to separate meter readings. Jumper cable
does not added significantly to the total circuit
length until 300 metres of jumper (will equal 1
metres of sensor cable. |
|
:: |
Need
specs on TT-PTB-1000 calibrator box. Expecting
resistance value(s), and +/- limits. |
:: |
The
TraceTek Portable Test Box does not have a
specification or data sheet. It is used to test
TraceTek cables for breaks and the presence and
location of water (liquids) and contamination on
the cables. |
|
:: |
What
is the warranty on TraceTek? |
:: |
One
year from date of purchase on cables, modules
and components. |
|
:: |
In
specs for TraceTek, it shows a four conductor jumper
cable wire (air plenum cable). What is it? |
:: |
The
four conductor wires are colour coded to match
the TraceTek cables. This jumper cable has been
UL listed as plenum cable, so it may be used in
plenum spaces without conduit. |
|
:: |
This
is for use in C1D2 area, how do you connect the
sensing cables to set the system up in accordance
with approvals? (specific junction box, stc.) |
:: |
The
sensing cable operates at low voltage, and
when driven by intrinsically safe output circuits,
may be located in Class I Division 1 (C1D1) hazardous
locations. The alarm module is normally located
in an ordinary area (although the TTG and TTA panels
may be located in a C1D2 area). Consult the product
data sheets for specific approvals information
on each product. |
|
:: |
Can
we bury TraceTek TT3000 outside underground? |
:: |
You
can use TT3000 for outdoor applications? but
it must be installed in an environment protected
from the elements (for example, under the cladding
on insulated piping). Without protecting it form
the elements, normal ground water, rain, or contaminants
may cause the cable to go in to alarm. |
|
:: |
Does
your fuel sensor detect vapours? |
:: |
It
will go into alarm if the atmosphere is saturated
with fuel vapours. |
|
:: |
Can
TT3000 withstand 2% hydrochloride solutions? |
:: |
The
TT3000 cable is a fluoropolymer construction
and very resistant to most chemicals: the data
sheet provides some data on chemical resistance.
Cable performance will not be impaired if the exposure
is of limited duration: however, after prolonged
exposure (weeks) it would be prudent to replace
sections exposed to ensure maximum effectiveness. |
|
:: |
What
are the classifications for control panels? |
:: |
TTA and
TTG have outputs rated as intrinsically safe, so
sensing cable connected the a TTB or TTDM may be
located in a C1D2 areas. However, a zener barrier
is required if sensing cable will be located in a
C1D1 area. (see Product Selection Guide H) |
|
:: |
Is
there a maximum circuit length you can run off
of a TTC sensing module? |
:: |
Our published
rating is 50 ft of cable. Our test data shows that
it will work with up to 330 ft/100 meters of sensing
cable (jumper cable is not counted as part of the
circuit length). However, if that much length is
involved, it is usually advisable to either have
additional sensing circuits, or use a locating system. |
|
:: |
With
TT1000, does the main box with display include
the map adjacent to the panel? |
:: |
The
graphic map is an integral part of the system.
However, since it must show the layout, it must
be created after the TraceTek system is installed.
This service is normally performed by the TraceTek
installer or specialist installer partner (it should
be a paid-for line item on the bill of materials
for the TraceTek system). |
|
:: |
Are
there caulks or putty’s that could potentially
damage the TT1000 cable? |
:: |
These
materials are unlikely to damage the cable,
however if they are conductive they can cause a
leak alarm. |
|
:: |
I
keep receiving a service req'd alarm on my TTDM-PLUS.
I tried to adjust the sensitivity of this, but
the sensitivity menu is not available on the unit.
What do I do? |
:: |
(a)
You are probably getting the Service Required
Alarm for a reason. If this is a TT1000 cable in
a computer room floor, check where the cable passes
by air handlers. Carbon black dust from drive belt
wear can collect on the cable. Use denatured alcohol
on a clean rag to clean the cable at these points.,
you could also remove the cable and wash it on
the top shelf of a dishwasher, connect both connectors
together.
(b) If the cable is a TT3000 cable inside a double contained pipe, check for
the presence of condensate from moist air. You can usually find it under the
cap at access point risers. The pipe should be dehumidified by blowing dry air
or nitrogen into the pipe until the leakage current displayed on the panel reads
less than reasonable. Then ensure the pipe sealing system is good and trap the
dry air or nitrogen in the pipe before sealing it.
To change the Sensitivity (Leak sensitivity) of the TTDM-PLUS panel,
1.
Press the Down-Arrow key
2. Push the Down-Arrow key until Sensitivity is displayed
3. Press the Enter key
4. Push the Down-Arrow key until you reach the sensitivity level you want.
IMPORTANT: Do not use the TT500x level unless you have TT5000 cable attached
to the panel.
5. Push the Enter key on the selected choice
6. Press the Esc key until you navigate back to the main menu.

To
access the SIM Status screen to see the leakage
current level (displayed as "Current: XXµA"): |
:: |
(a)
In normal display mode, use the Left or Right
Arrow keys to select the SIM channel of interest.
(If you only have one cable connected to the TTDM,
there will be only one selection.)
(b) Press the Down-Arrow key to access the detailed status information.

|
:: |
Can
plastic connectors be connected to metal connectors? |
:: |
Yes,
TraceTek makes adaptors that will allow you
to convert metal to plastic and vice versa. These
adaptors will also allow you to convert from male
to female as well. So, it is possible through use
of an adaptor to convert a female plastic connector
to a male metal connector using a TT Adaptor-F/PC-M/MC. |
|
:: |
On
a TTDM controller does the 4-20 output latch with
the mA correlating to the leak location until the
discrete leak relay output is reset via the control
panel? |
:: |
No.
The 4-20mA output simply changes the current
with the changing conditions sensed by the Controller.
If the leak were to move, the 4-20mA output would
change - relaying this to the TTDM - which would
display the new leak location as "Re-Alarm
nn mt" or "Re-Alarm [nnnn]" if a
new leak occurs some distance from the original
leak. |
|
:: |
At
what PPM will TT5000 cable sense a leak for crude
oil. There may be some leakage into the surrounding
soil already and we want only to alarm if there
is a leak from the pipe. |
:: |
Our
hydrocarbon sensor cables will not respond
to contamination less than 25000 ppm, which is
about the maximum level that can be dissolved in
water. In a case with possible existing soil contamination,
the problem may be more complex than that. If there
is free fuel in the soil, then we only require
a few millilitres in contact with the cable to
cause an alarm. One scenario is that the soil is
cleaned up to a depth below the sensor cable installation,
but some contamination exists below that. If the
ground water level ever rises to the sensor, it
will push the fuel up with it and then cause an
alarm. |
|
:: |
How
many TT-MBC-PC 's can be connected in series to
create branches? |
:: |
The
total system length is a combination of cable
and any other device connected to the TTDM-PLUS
or SIM-1 which adds resistance to the circuit.
Each Modular Branch Connector (MBC) adds. 9 m (30
ft) to the length of the circuit due to its internal
resistance (4.5 mtrs). per outgoing branch). As
long as the combination of cable and MBC’s
does not exceed 1,500 metres on a TTDM-Plus or
SIM-1 module, you can connect as many as needed. |
|
:: |
Will
new TT1000 cable work with an old controller, model
TTB-FA? Is there a dealer in Atlanta? |
:: |
Yes,
the TT1000 leak detection cable will work with
TTB-FA monitoring panel. |
