NOTRAFFIC AEX-AR95X Sensor Unit
Federal Communications Commission (FCC) Notice
NOTE : This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
This device complies with Part 15 of FCC Rules. Operation is subject to two
conditions: (1) This device may not cause harmful interference, and (2) this
device must accept any interference received, including interference that may
cause undesired operation.
Changes or modifications to this equipment not expressly approved by the party
responsible for compliance (NoTraffic Ltd.) could void the user’s authority to
operate the equipment.
Introduction
A typical NoTraffic installation consists of one Sensor Unit (SU) for each
intersection approach (typically 4). and one control unit (CU) installed
inside the cabinet and connected to the traffic controller. One of the Sensor
Units per intersection, is a V2X / DSRC unit, which uses Vehicle to
Infrastructure communication protocols, enhancing the performance of the
entire system, by added connected vehicle tech. Identify this unit, according
to label on box and added hardware (antennas, surge suppressors and short
ground cables), for further reference (below).
Sensor Unit Installation
(Repeat for each sensor unit)
Astro-Brac mounting
The recommended location for installation is in the center of theapproach on
the highest point available, total height including Astro-Brac should be 30
feet or more.
The V2X Sensor Unit should be mounted facing the main street
with a minimum field of view obstruction to provide the best possible range for V2I communication.
Example location: on the luminaire arm, or traffic light mast arm.
Height is more important than having the Sensor Unit in the center of the
approach. Consult NoTraffic team on best possible location, prior to
installation, if not clear.
Mount Astro-Brac per manufacturer’s instructions.
Mount Sensor unit onto Astro-Brac
- Mount the SU to the Astro-Brac using the provided 2x M10 bolts, locking washers and nuts.
- Do not fully lock screws, until aiming phase is completed.
- On the V2X Sensor Unit, attach two provided Surge Suppressors, and on them attach two provided antennas. Use two provide ground cables to ground Surge Suppressors to two ground studs on bottom chassis. Then ground one of the studs to a well-grounded connection on the traffic pole itself, or inside the luminaire. Verify that the V2X antennas are firmly installed.
Powering the V2X module without properly connecting BOTH antennas will cause permanent damage to the unit.
While mounting, note that the camera is facing in the direction of the
upcoming traffic. On the bottom back side of the Sensor Units there is the
back compartment, which holds the AC inlet, fuse, and RJ45 maintenance port
(hidden behind closed gland).
Connecting AC power
- Pull an AC cable (mains power – 110VAC) to Sensor Unit.
- Release 4 captive screws on back compartment and open cover.
- Slide AC cable through open cable gland on back compartmentcover. Then connect AC cable to AC inlet, as shown:
- Close back compartment cover, tighten 4 captive screws and then tighten cable gland firmly on AC cable.
Aiming the Sensor Unit
Move Sensor Unit Up/Down and Left/Right, according to instructions over the
phone from NoTraffic’s NOC.
When NoTraffic’s NOC says Sensor Unit is aimed, tighten two bolts on Astro-
Brac to lock Sensor Unit in position.
Finishing installation
- Check for mechanical integrity of the Sensor Unit and Astro-Brac. 2.5.2 Attach excess AC cable to pole, using cable ties.
