Rear View Safety
The RVS-112-W Vehicle Reversing Aid is an automatic back up alert system
that warns drivers of potential obstacles while backing up their vehicle. Using
ultrasonic echo location sonar technology the system is activated when the
driver engages reverse gear. A 4 zone variable audio pulse alerts the driver of
potential obstacles. The audio pulse intensity increases and the audio frequency changes as the vehicle backs closer to the obstacle. As with all sensing systems there are blind areas in the sensing patterns due to the cone or triangular
nature in the way the sonar pulse is emitted. Whenever an object moves from a
covered area and into one of these blind areas a special warning alert message
and a very loud tone will be transmitted twice or until the operator takes the

vehicle out of reverse. This is especially helpful for detecting moving objects
such as a pedestrian, an animal, a forklift or other moving vehicles that may be
behind your vehicle and in harms way.

Before drilling please check that no cable or wiring is on the other side
of the wall. Please clamp all wires securely to reduce the possibility
of them being damaged while vehicle is in use. Keep all cables away
from hot or moving parts and electrical noisy components.
We recommend doing a benchmark test before installation
to insure that all components are working properly.
PLEASE READ THE ENTIRE MANUAL AND FOLLOW THE INSTRUCTIONS AND
WARNINGS CAREFULLY. FAILURE TO DO SO CAN CAUSE SERIOUS DAMAGE
AND/OR INJURY, INCLUDING LOSS OF LIFE. BE SURE TO OBEY ALL APPLI

Sensors
Drill four holes at equal distance in the rear bumper and mount the
sensors using the included grommets. Run each cable to the sensor
box and plug each into its corresponding port.
Power
Connect Y-adapter to the waterproof control module. Connect the RED
wire to a 12V constant power and the GREEN wire to a 12V reverse
power. Connect the BLACK wire to a chassis ground.
Sensor Cable
The sensor cable attaches to the waterproof control module on one end
and the 4 sensors on the other.
The Multiplexer
The cable that runs through the vehicle now carries signals both from
the backup camera and the sensors. Plug this cable into port #3 in the
Multiplexer. In order to hear the sensor audio alerts, connect the blue
SETUP
trigger wire (coming o the multiplexer) to 12V reverse power.

1) The width of vehicles vary. It is important to install the Sensors at
the appropriate distance and location along the rear bumper or equivalent Assuming that the width of vehicle is L, then the space between
Sensors is 1/4L (Sensors must be mounted S1, S2, S3, S4, from left to
right).
• Sensors S1 and S4 should be located approximately 1/8L from either
side of the vehicle. S2 and S3 will be located 1/4L from S1 and S4.
If the Sensors are mounted on a DOT type bumper, the Sensor locations are determined by the vehicle width (L), not the width of the
bumper. 2) Sensors should be mounted at an absolute minimum of 16
inches (40cm) to 32 inches (80cm) from the ground (20 inches (50cm)
is a good choice, if available). See Alternate Sensors Mounting Locations, for other options.
INSTALLATION

Rear View Safety
Sensor Installation (In-Bumper Flush Mount)
For vehicles equipped with a bumper that can accommodate the Sensors,
carefully drill a 25mm hole and insert the Rubber Jacket, properly orientated
“UP”, in the hole rst. Then insert the Sensor, again properly orientated “UP”
Depending on the thickness and construction of the bumper, the hole diameter may need to be varied. The Rubber Jacket is designed to seat properly
into a 25mm hole with a 1/8 inch (3.2mm) thick metal bumper. If this is not
the case, the anges on the Rubber Jacket must be taken into consideration.
It is suggested that a test hole be utilized to conrm a proper t.

Alternate Sensor Mounting Locations
The system is designed to be installed with all 4 (four) Sensors aligned
across the rear of the vehicle, preferably at a height ranging from 16” to
32” from the ground. When the Sensors are installed in a dierent layout
(for example to detect a building overhang as shown below), please consider the following:
• Each Sensor detects objects in a circular area approximately 20” in di-
ameter.
• It is recommended that the face of all Sensors should be on the same
plane to ensure the accuracy of the system.
• When the Sensors are placed on two dierent levels (per the example
below) install S1 and S4 on the top and S2 and S3 on the bottom of the
vehicle.

Rear View Safety
Sensors can also be mounted across the front of the vehicle to detect building
overhangs or to detect objects out of view.
NOTE: These sensors are a tool to help the driver. The driver should always
know what is in front of or behind them and physically check the area themselves.
Alternate Sensor Mounting Locations
ALTERNATE MOUNTING
CAUTION: Using less than 4 (four) Sensors across the width of a bumper will create limited coverage resulting in blind zones! It is strongly suggested that these blind zones
are mapped out to educate the driver regarding the system limitations.
Reverse With Condence ™
11
Having all four Sensors in line, on the same plane, provides the best result. If you
break the Sensor conguration up, for example two on top and two on bottom,
you create a bigger gap between the Sensors, causing a large blind zone area.
This blind zone area can lead to objects or people being undetected by the Sensors.
Control Module Installation
1) Depending on the vehicle type, select an appropriate location to mount
the water-tight control module on the rear undercarriage of the truck chassis.
