• Select a spare connector between zones 1
to 8.
• Zones 1-2 do not require the insertion of a
zone expansion card, MZA-EXP.
• Three cards can be added to the base unit,
giving a total of 8 individual zones. Provided
the relevant zone expansion card has been
• the relevant zone expansion card has been
inserted, you can select any sequence for
connecting the sensing cable or sensing
devise.
Important: Observe the colour coding.
If wires are not connected to the correct
terminals, the leak detection system cannot
operate properly.
Insert the sensing cable (SI) plug into the SI
socket (item 15, 17, 19, 21 on the product
illustration on the rst page).
ISOLATE SPARE SENSING ZONES
Each spare sensing zone circuit or the second
zone in any of the two zone blocks, where
an expansion card is tted, that is not to
be used must be terminated with loops of
cable between red-green and yellow-black.
(See gure 5). This will prevent the system
identifying this zone as having a cable break.
However, should there be a requirement for
all three-expansion cards to be installed, but
not used, then these must be terminated in a
similar fashion.

F. CONNECTING THE ZONE EXPANSION CARDS
Important: The MZA-EXP is an electronic unit. During installation, take the following
precautions to avoid damage to its electronic components:
• The MZA panel should not be powered
when installing the MZA-EXP card.
• Anti static precautions should be taken
before touching the boards inside.
• Handle with care, avoid mechanical
damage.
• Keep the electronics dry.
• If handling circuit boards, hold them by
their edges to avoid physical contact with
electronic components.
• Avoid exposure to static electricity.
• Avoid contamination with metal lings,
liquids, or other foreign matter.
• A maximum of three MZA-EXP cards can be
added to a MZA panel.
• Each MZA-EXP provides two additional
zones of sensing.
• Remove the card from it’s static free
packaging.
• Insert the rst card on vertical connector
marked zones 3-4 and the following cards
on zones 5-6 and zones 7-8. The card will
only t in one direction.
• Push the card securely to the base
connector.
• Once the card has been securely installed
the MZA panel can be powered.
INSTALL ZENER BARRIER, IF
APPLICABLE
When sensing cable will be located in Class
1, Division 1 locations, approval agencies
require that the sensing cable be protected
with a zener barrier between the sensing
cable and the MZA 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 your distributor/agent to
select the proper zener barrier. One will be
required for each sensing zone.
When installing a zener barrier, wire
it in accordance with the instructions
provided with the kit.

VOLT FREE RELAY OPERATION
All leak detection alarm panels supplied by Aquilar are provided with, at least one, volt free
relay.These are also known as volt free contacts or dry contacts. They are used to operate
auxiliary equipment such as – valves, sounders, pumps, beacons etc., sending closed or open
contact signals to Building Management Systems (BMS) or other logic level controls.
As the name suggests, there is no voltage present at the terminals. So, to operate a valve,
for example, you need to have a dedicated power supply which is then fed through the relay
(typically the live feed) to switch it on or o accordingly.Typical wiring is as follows:
Please ensure that the load does not exceed the ratings of the volt free relay. This is stated in
the relevant product’s data sheet / installation instructions.
Wiring of volt free relays should be undertaken by a suitably qualied technician and in
accordance with the regulations and standards in their industry/country. These notes are only
intended as a guide and Aquilar Ltd bears no responsibility for the installation or operation of
the unit.

G. TEST PROCEDURE
1. After connections are complete supply
power to the unit. If the sensing circuit
is complete and free of leaks or other
problems, the green Monitoring LED only
will illuminate.
2. Leak Simulation: For systems using TT1000,
TT3000 sensor cable or a detection probe,
use a TraceTek Mapping Tool or a small
container of water to simulate a leak. After
the time delay has expired (maximum 15
seconds) look for the following indications:
Red LEAK LED on
Green POWER LED on
LEAK RELAY in ALARM condition
(Note: This may cause equipment shut
down if devices are connected to the LEAK
relay contacts)
Remove simulated leak
Red LEAK LED goes out
For TT5000 and TT5001 systems, simulate a
leak condition by tightly bending and holding
the sensor cable.
3. Cable Break Simulation: For any sensor
system, disconnect any one wire at the
sensor cable terminal block or disconnect
any connector in the system. Look for the
following indications:
Yellow CABLE BREAK LED on
FAULT RELAY in ALARM condition
Restoring the connection should cause the
MZA to return to the normal indications for
that zone.
1. Complete a system inspection in the
presence of the owner.
2. Ensure a plan showing the location of the
sensor is available.
3. Check that the following information
is clearly visible adjacent to the alarm
module:
• In case of alarm instruction.
• Location of the system map in case it
is not installed adjacent to the alarm
module.
• Name and contact number of the person
responsible for operating the system.
• Supplier’s contact name and address.
4. Hand over these Installation, Operating
and Maintenance Instructions.
5. Make the owner aware that it is strongly
recommended to perform a systems
check at regular intervals, at least every six
months.
H. FINAL CHECK LIST

COMMISSIONING
Your system should be commissioned
by an authorised AquiTron™ or TraceTek
representative. The system map is a crucial
part of the system and should be located
adjacent to the unit and within the O&M
documents.
Important: Store hardware and
documentation supplied with the MZA in a
secure place for later use (commissioning,
connecting interfaces, operating).
I. INVESTIGATING LEAKS AND FAULTS
If the location of a leak is not apparent, it is often useful to subdivide the leak detection
circuit, as illustrated below. To accomplish this, it is recommend have a TraceTek Portable
Test Box (PTB) and an extra Modular End Termination is used. Contact your local TraceTek
representative to obtain these products. Note that the PTB comes with instructions on how to
use it.
To segment the system (one individual zone) and isolate problems, nd a TraceTek sensing
cable or jumper cable connection at a convenient point somewhere at the center of the

detection circuit. You can then use a PTB to check one portion of the system (to verify circuit
integrity, to detect the presence of liquid, and even to determine its location, as the PTB will give
you an indication in feet or metres to the point of the leak). If you install an end termination on
the other length of cable (going back to the MZA panel), you can use the MZA to check the “front
half” of the sensing circuit.
You can further subdivide the circuit, and even test individual lengths of cables, as shown in the
third diagram below. Even the most perplexing problems can usually be isolated and resolved
using this methodical approach.

J. CLEANING THE MODULE
To clean the outside surface, use a damp
cloth or sponge. Do not use solvents or
abrasive cleaners, and do not open the
enclosure while it is wet (it is an electrical
device).
L. FUSE REPLACEMENT
The fuse on the power supply board (item 7
on the internal layout drawing) is a 1600-mA,
250-V. Use no other type of fuse or the MZA
could be damaged or fail to perform properly.
A spare fuse is provided and positioned on
the mother board item 4.
K. STORAGE AND HANDLING
OF SENSING CABLE
M. NOTE ON CABLE
CLEANING
Despite their rugged construction, TraceTek
sensing cables must be handled in a
manner appropriate for a sensing device
or they may be damaged and require
replacement. Therefore, you should follow
some basic rules for storing and handling all
TraceTek sensing cables:
• Store spare cable in its original container
in a clean, dry place until ready for
installation.
• Schedule cable and probe/sensor
installation after all mechanical, plumbing,
and electrical work has been completed.
• Clean the area where the cable is to be
installed, and remove any obvious debris
or other sources of contamination.
• Do not solder or weld near the cable
without providing protection from heat,
solder ux, or weld splatter.
• Do not drop tools or oor tiles on the
cable; sharp and heavy objects may
damage the cable.
• Avoid walking or stepping on the cable.
Provide shielding (for example, a half
shell of plastic pipe) where additional
protection is necessary.
• Do not use tape to secure sensing cable
(some tapes and adhesives absorb
moisture) or use solvents that could
eventually cause an alarm.
• Do not drag sensing cable through
contaminants (such as pipe dope, PVC
cement, solvents, oil, or dirt).
TraceTek TT1000 and TT3000 use a solid
core polymer construction and can usually
be easily cleaned with tap water. In extreme
cases or when large amounts of cable are
contaminated, either cable can be washed
in an ordinary dishwasher. Try a water only
(no detergent) cycle rst and avoid the
heated dry cycle. When placing the cable in
the dishwasher be sure to tightly connect
the male connector on one end to the
female connector on the other. Keep water
out of the connectors.
TT5000 and TT5001 cannot be cleaned
without special equipment. These cables
normally require replacement after
exposure to fuel or solvent.
N. PERIODIC MAINTENANCE
AND TESTING
Recommended Interval: Perform a
functional check per the following procedure
at 6-month intervals. Repair or replace all
damaged wiring and senor cables. There are
no eld repair procedures for the MZA panel.
If the module fails to perform the functional
tests it must be replaced

O. TROUBLE SHOOTING
Problem:
Leak Alarm, but no leak is found.
Possible Cause:
Cable is dirty (TT1000, TT3000).
Action:
Clean cable using water (no solvents, acetone,
white spirit or turps). Dry the cable and
check MZA front panel. Heavily contaminated
cable may require replacement. But if dirt is
accumulating, cleaning and/or replacement
will eventually be required.
Problem:
Leak Alarm, but no leak is found.
Possible Cause:
Cable is exposed to occasional water spraying
(TT1000, TT3000)
Action:
It is best to keep the sensor cable at least
1 meter (3 feet) from the outow of any air
conditioner units.
Problem:
Leak Alarm, but no leak is found.
Possible Cause:
Cable is in contact with sharp metal edges
(TT1000, TT3000)
Action:
Check the sensor cable for possible points of
contact with sharp edges such as the edges of
drip trays or the pipe threads on adjustable
oor supports, trunking and ducting.
Reposition the cable as necessary or insert a
small piece of insulating material to prevent
the cable from making contact with the metal
edge.
Problem:
Leak Alarm, but no leak is found.
Possible Cause:
Cable is pinched (all cables).
Action:
Check the sensor cable for possible pinch
points. TT5000 and TT5001 can be tripped if
tightly bent or compressed by a heavy object.
TT1000 and TT3000 can be tripped by heavy
pressure from a metallic object. Check the
entire cable installation for pinch points and
correct the condition.
Problem:
CABLE BREAK indication but cable appears to
be intact. Possible
Cause:
Loose connections at terminal block.
Action:
Check all terminal block screws for tightness.
To test the module by itself, use two small
pieces of wire to form temporary jumpers
from red to green and yellow to black at the
sensor cable terminal block. This simulates
a very short piece of sensor cable and the
yellow CABLE BREAK LED should go o. If the
MZA cannot pass the jumper wire test it may
require replacement.
Problem:
BMS/PLC or other host system detects a
fault when the MZA is operating in NORMAL
mode.
Possible Cause:
Mains power has cycled. Logic controller has
powered relays incorrectly.
Action:
Press RESET button. This will clear any logic
power up anomalies, and the panel will now
function correctly.
