General description
The QuikTrak Hybrid Transponder (QHT) is a tracking
device principally designed for use in vehicles. It operates
on a Quiktrak Network and can use either a Quiktrak spread
spectrum transmission or GPS coordinates to generate
location information for the end user. It has a duress
function, one general alarm input with either +ve or –ve
triggering and one relay driver output. It is fitted with a
Lithium Ion backup battery for operation in the event that
the main vehicle supply is disrupted.
Wiring harness
The QHT wiring harness provides connection for all the
inputs and outputs. Wire colours and functions are detailed
in table 1.
QHT mounting orientation
The QHT is fitted with an internal, directional, active GPS
antenna. It needs to be orientated within the vehicle in such
a manner that the GPS antenna is facing towards the
satellites. Figure 2 shows the location of the antenna within
the module and Figure 3 shows the orientation of the device
required to achieve a view of the satellites.
QHT location
Because of the GPS antenna constraints, care must be taken
to locate the module in a suitable position within the vehicle.
Figure 4 shows some suggested locations. Make sure that
there are no large pieces of metal directly above the antenna.
Quiktrak antenna location
The Quiktrak antenna, which is used for communications
with the Quiktrak network, can be located anywhere within
the vehicle. The antenna can be flexed, but it should not be
folded. The antenna should not be mounted directly to a
metal surface. The foam wrapping around the antenna is the
absolute minimum spacing to any metal surface within the
car. The antenna should be well hidden within the vehicle.

Alarm Input
The QHT has a single alarm input which can be triggered
from either a positive or negative signal. Only one or the
other can be used, not both. If the POS trigger input is to be
used (blue wire) then the NEG trigger input (green wire)
must be connected to vehicle battery –ve (ground).
Alternatively, if the NEG trigger input is to be used, the
POS trigger input must be connected to vehicle battery +ve.
Make sure the QHT has been enabled on the network before commencing installation

Duress Input
A duress alarm function is also provided on the QHT. The
two brown wires should be connected to a switch that is
positioned within the vehicle such that it is hidden but still is
able to be easily operated by the driver.
The brown wires should never be connected to vehicle
battery +ve or –ve.
Relay Output
A single output capable of driving a relay is provided. The
output is a current sink, that is one side of the relay coil is
connected to vehicle battery + ve and the other side of the
relay coil is connected to the yellow wire.
The maximum current that the yellow wire can sink is
250mA.
Vehicle Voltage Supply
The red wire on the cable harness is connected to the vehicle
battery +ve and the black wire is connected to the vehicle
battery -ve (gnd).
Backup Battery
The QHT is fitted with an internal Lithium-Ion backup
battery. Before the QHT is installed in the vehicle, the
backup battery needs to be enabled. This requires that the 4
screws that hold the lid on the QHT enclosure are removed.
With the wiring harness positioned to the left of the
enclosure, a small jumper can be seen inside the QHT on the
left hand side between the wiring harness and the edge of
the QTM module. The jumper should be moved to the top
horizontal position. Figure 5 shows the jumper in the
battery enabled position. Refit the enclosure lid and 4
screws.

Installation Check
Before completing the QHT installation, a check should be
carried out to ensure that it is operating correctly. Contact
your monitoring organization and make sure that the QHT
can be tracked. Activate a duress alarm as a test and ensure
that the monitoring personnel receive the duress alarm
notification. You will need to know the network ID number
printed on the label to do this.
