SmartSensor Matrix
SPAN WIRE MOUNT INSTALLATION QUICK START GUIDE
e SmartSensor Matrix can be installed in two ways:
On a pole or mast arm, using the SmartSensor mount.
On two vertically aligned span wires, using the SmartSensor span wire mount.
ments in this case; see the knowledge base article called Using the Span Wire Mount for more information.
is document will cover installations using the span wire mount. For the regular mount, see the SmartSensor Matrix quick start guide.
1
Choose a mounting o set
Note.
e mounting location for your SmartSensor Matrix sensor(s) should have already been determined as part of the design pro-
cess. If it has not been, please consult the SmartSensor Matrix User Guide for complete design
and installation guidelines.
Use the table at right to choose a suitable o set (distance from the rst lane of interest), based
on the height of the span wires you'll be mounting on.

Mount the sensor

Align the sensor to the roadway

1
Tilt the sensor down so it is aimed at the center of the lanes of
interest.
2
Adjust the side-to-side angle so that the sensor's 90º eld of
view covers the approach.
Note. Make sure the front edge of the sensor's footprint covers
beyond the stop bar. is allows you to detect vehicles that do not
stop at or behind the stop bar.

1
Prepare the sensor while still on the ground: remove the large bolts holding the end knuckle (the
one with four holes) to the mount, then use the four small bolts and lock washers to attach the
removed knuckle to the sensor backplate.
2
Secure a span wire hanger assembly, namely the PELCO SP-1050-FL-L-SP0003 or SP-2045-FL-L,
to the top and bottom span wire. If the hanger assembly is too long for the location and part of it
hangs below the span wire, we recommend that you cut o the excess. If the hanger assembly is
too short for the location, switch to a hanger assembly with a longer extension bar.
3
Use the 5/16 bolts that were included with the Pelco hanger assembly to attach the rest of the
span wire mount to the hanger assembly (the knuckle with six holes is the one that attaches to
the span wire assembly). It's recommended that you put the mount roughly in the middle of the
extension bar, for stability.
4
Attach the knuckle/sensor 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.
