This ultrasonic detection system is designed to provide an additional
alert for driver awareness of a hazard present within the drivers
blindspot area when the vehicle is turning. This system is primarily
used for commercial vehicles.
Care must be taken when installing this accessory to ensure damage does not occur to the
vehicle. The installation of this accessory should follow approved guidelines to ensure proper
installation. Read entire instructions thoroughly before starting. EchoMaster is in no way
responsible for any damage that may occur during installation.
Note: Under no circumstances should you attempt to open the control box or any other
component. Doing so will void all manufacturer’s warranties.

Fitting Instructions
Recommended Tools for Installation
u High torque drill.
Use on Slow Speed (approx 400 rpm)
u Marker Pen for marking holes prior to drilling
u 1/8” carbide tipped drill bit for starting pilot hole
u Hole Saw 24mm (included)
u Pliers, Crimpers & Soldering Iron
u Multi-Meter
u Zinc galvaniser or a rust inhibitor for metal
u Safety goggles
Optional Tools
u Panel tool (for situations requiring
plastic, inner panels to be removed)
u Phillips screwdriver
u Wire pulling tool (for routing wires)
u Semi-circular metal le (for smoothing
hole edges when necessary)
DO NOT use ngers to test holes
for burrs or smoothness.
PLEASE NOTE
For vehicles with metal panels, it is recommended to install with rubber sleeves using the 24mm hole saw
provided. If installing without the rubber sleeves, use a 22mm hole saw, which is not included.
Determining Sensor Position: Measure Twice, Cut Once!
Inspect behind the panel in the approximate mounting area to check for any possible
obstructions.
A proper installation will take into consideration two factors:
(1) Placement: height and distance.
(2) Angle: accurate detection depends on the correct sensor angle.
Each sensor head requires a 50mm clearance space behind the panel to be completely inserted.
Some areas have an outside cover or fascia and a metal backing. You may have to drill through
both layers to ensure you have enough clearance in order to t the sensors.
PLEASE NOTE
When routing cables be careful of hot engine parts and/or sharp edges under vehicle.

Fitting Instructions (continued)
u The Sensor heads can be mounted onto or into the body of the vehicle by two methods,
either drilling and ush mounting or by using the supplied bracket.
u If the sensor heads are to be ush mounted in a metal panel, then the supplied rubber sleeve
must be used.
u If installing with the metal bracket then the supplied rubber sleeve must be used.
u Please mount the sensors at right angle to the ground, or slightly angled upwards.
- Note the top of the sensor head - it is marked with a small dot on the front face.
u Sensor heads should be spaced between 1m and 2m max distance, with the rst sensor
on the front corner of the vehicle all sensors should have a height of 0.6m to 1.1m.

The Sensor Holes
Using the provided hole saw, drill the sensor holes. Always wear approved safety glasses when
drilling. If drilling a metal panel, coat edges of holes with Zinc galvaniser or rust inhibitor.

Fitting Instructions (continued)
Connecting the Power Harness
You will need to nd and connect the following inputs
u Switched ignition live – RED
u Turn signal – Orange (labelled)
(Left or Right depending on tment),
u Footbrake – Red (labelled)
PLEASE NOTE
It is recommended that all connections are soldered.
NEVER USE A TEST LIGHT TO PROBE WIRES
Once the pickup point wires are found, connect the red wire to the Ignition, orange wire to the
appropriate turn signal wire, red wire to the footbrake wire and the black to a suitable earth point.
Running Sensors to Control Module
Many vehicles will have factory grommets to allow routing of wires from the outside to the inside
of the vehicle. If you are drilling a hole through a metal body panel to route the sensor harness
into the passenger compartment, use a suitable rubber grommet, protect any bare metal with a
zinc galvaniser or rust inhibitor and route to the control module.
Mounting the Buzzer, Warning LED & Push Button Switch
The buzzer has 3 adjustment positions: Hi, Low, and Off. You usually want to keep the buzzer on
the same side of the vehicle as the control module for ease.
The Warning LED should be placed within the drivers eye-line, it has a self adhesive backing for
mounting, route the cable behind an adjacent trim panel.
The Illuminated push button switch is designed to be panel mounted, nd a suitable mounting
position or an unused switch blank and drill a 8mm hole.

The Side Alert System will turn on with the ignition and enter standby mode this is depicted by
the LED ashing once and the Green LED on the activation switch illuminating. The Side Alert will
become fully active when an input trigger has been detected.
Once an object is detected within the range, the system will alert the driver via audible tone or
visual indicator. The Side Alert system can be temporarily deactivated by pushing the illuminated
push button switch. When deactivated the Green LED will extinguish. To reactivate the system,
press and hold the push button for 2 seconds
PLEASE NOTE
The chart reects the default zone range. Performance may be affected by the following: Heavy rain, Ice or
Snow. Please keep sensor heads clean from dirt and debris.
