3.4.1 Sensor Direction
The sensor should be mounted in an upright position with the cable exit on the sensor pointing
downwards, such that the Brigade logo on the front of the sensor is readable when standing in
the required detection area. The front of the sensor should have line of sight to all areas where
objects should be detected.
3.4.2 Sensor Fixing
The unit is supplied with four M5x30mm screws and four M5 polymer locknuts for mounting
purposes. The recommended torque is 6Nm or 50 inch/lbs.
3.4.3 Vehicle Overhang into Detection Area
It is recommended that the mounting position on the vehicle should avoid any vehicle furniture
overhanging into the detection area, as such objects will cause false alarms (for exceptions
refer to section “1.2 Object Detection Capability”, paragraph “Warning”).
The detection area of the Brigade Backsense
®
radar beam has a 140° horizontal angle to the
maximum designated width and a vertical angle of 16°, see section “1.2.1 Detection Pattern”
for details.
If such a scenario is unavoidable, the Backsense
®
System can be configured using the Blind
Area setup feature to ignore objects in the detection area; see section “4.3.11 Blind Area
Setup”.
3.4.4 Mounting Angle
Brigade recommends mounting the radar on a bracket (available from Brigade, see Section 2
“Kit Contents”), which can have its angle adjusted relative to the horizontal plane to optimise
performance. The table below suggests adjustment angles depending on the sensor
installation height on the vehicle. Note that the angles stated are dependent on the vehicle
face that the bracket is mounted on being 90° relative to the ground.
Depending on the vehicle, working environment, and typical objects to be detected, an
adjustment of a few degrees around the suggested values can improve the detection
performance or avoid false alarms.

Depending on the required mounting height of the sensor, either the angle needs to be
adjusted or the distance to ground level must be longer than the selected detection length.
3.4.5 Offset to Vehicle Centre Line Mounting
If the Brigade Backsense
®
System is fitted off-centre or at an angle to the vehicle centre line,
the detection area (see section “1.2.1 Detection Pattern”) is likely to be incorrect or misaligned
with the vehicle width or direction of travel.
