SmartSensor Advance
INSTALLATION QUICK START GUIDE
1
Choose a mounting height
The minimum recommended mounting height is 17 ft. (5.2 m) and the maximum is 40 ft. (12.2 m). Mount the sensor as high as
possible to reduce the chance of same-lane occlusion.
1
Prepare the sensor while still on the ground: remove the large bolts holding
the end knuckle to the mount, then use the four small bolts and lock wash-
ers to attach the knuckle to the sensor backplate.
2
Once you’re ready to mount the sensor on the pole, insert the mounting
straps through the slots on the mount.
3
Position the mount on the pole in the spot you chose from the previous step.
4
Tighten the straps.
5
Attach the knuckle you prepared earlier to the mount using the large bolts
(the cable connector should be pointed down). Don’t tighten completely yet,
as you still need to align the sensor to the roadway.
1
The target is the exact spot on the road that the sensor should
be pointing at. Find the distance to the target by using the sen-
sor’s height and offset in the table at right.
3
Align the sensor to the roadway
2
Mount the sensor
Note.
The mounting location for your SmartSensor Advance sensor(s) should have been determined as part of the design pro-
cess. If it hasn’t been, consult the
SmartSensor Advance User Guide
for complete design and installation guidelines.
1
Connect a 12 AWG grounding wire to the grounding lug on the bottom of the sensor.
2
If the intersection is bonded, connect the other end of the grounding wire to the earth ground for the pole the sensor is on. If
the intersection isn’t bonded, run the grounding wire down the pole, alongside the cable, back to cabinet ground.

Tilt the sensor down to aim its center at the target.
3
Roll the sensor so that the radar beam footprint lines
up with the road, as shown at left.
