2.4 Safety Messages Contained in this
Manual
The following safety messages appear in this
manual:
WARNING
This equipment has been approved for mobile
applications where the equipment should be
used at distances greater than 20 cm from the
human body (with the exception of hands,
wrists, feet and ankles). Operation at distances
less than 20cm is strictly prohibited.
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.
NOTICE
This Class A digital apparatus complies
with Canadian ICES-003.
Cet appareil numérique de la classe A
conforme à la norme NMB-003 du
Canada.
IMPORTANT NOTE
Modifying the radio/GPS unit may seriously
damage the equipment and void the warranty.
Do not attempt to modify the radio/GPS
circuitry in any way. Modifying the radio
and/or antenna in any way may cause the radio
to violate FCC/IC requirements.
REMARQUE IMPORTANTE
La modification du système radio/GPS risque
d’endommager sérieusement le matériel et
d’annuler la garantie. Ne pas tenter de modifier
les circuits du système radio/GPS de quelque
façon que ce soit. En modifiant le système radio
et/ou l’antenne de quelque façon que ce soit, la
radio risque de ne plus répondre aux exigences
de la FCC/IC.
WARNING
Vehicle batteries contain sulfuric acid and
may contain explosive gases. Keep sparks,
flames, and cigarettes away. Wear eye
protection. Disconnect the negative cable
first to prevent shorting the positive terminal
to the chassis when removing the positive
cable. Battery acid may cause skin irritation
and eye injury. Explosive gases may cause
severe injury or death.
Vehicle Equipment Installation Instructions 5
WARNING
A completed installation that is not tested may
result in improper system operation, which may
result in accidents and/or injuries. To avoid this
problem, test the system to verify proper
operation. Improper system operation may
result in unsafe driver action.
CAUTION
Failure to replace the fuse size as marked may
cause property damage. Replace fuse size as
marked.

2.6 Safety Considerations
Please consider the following safety issues before
beginning the installation of the Opticom™ GPS
System vehicle equipment.
Although we have compiled this list of common
safety considerations, it should not be considered
as complete. It is not intended to take the place
of your good judgment, training, and experience.
2.6.1 Personal Safety Equipment and
Clothing
Personal safety equipment and clothing including
high visibility vests, hard hats, gloves, electrical
shock or electrocution protection clothing and
equipment, safety shoes, safety glasses, face
shields, goggles, and hearing protection devices
are just some of the items available to you.
Choose the right equipment for the job. If you
are unsure of which safety equipment is
recommended or appropriate for the job, ask
your supervisor or foreman.
2.6.3 Explosion
Common automotive-type batteries produce an
explosive gas under some conditions. This gas
may easily be ignited by a spark or flame as you
work on the vehicle. To reduce the risk of
explosion, disconnect the battery, work in a
well ventilated area, avoid the use of devices
that create sparks or use open flames, and use
the appropriate personal safety equipment and
clothing.
If you are unsure of which techniques,
procedures, and protective equipment are
recommended or appropriate for the job, ask your
supervisor or foreman.
2.6.4 Chemical Burns
Common automotive-type batteries contain strong
acid that can cause personal injury if you come in
contact with the acid. To reduce exposure to the
risk of chemical burns, wear appropriate
protective clothing and handle the battery with
care.
2.6.2 Electric Shock
As a trained installer of electrical equipment you
are aware of the dangers associated with
installation of electrical devices. Always be sure
that the power to the equipment, and all associated
equipment, is turned off and the vehicle battery is
disconnected. Use the equipment, techniques,
and procedures that you learned during your
training or apprenticeship or other electrical
industry recognized safety procedures.
If you are unsure of which techniques,
procedures, and protective equipment are
recommended or appropriate for the job, ask your
supervisor or foreman.
If you are unsure of which techniques,
procedures, and protective equipment are
recommended or appropriate for the job, ask your
supervisor or foreman.
2.7 Disposal of Device
Please dispose of the device in accordance
with all local, state, and federal laws and
regulations.
2.8 FCC Statement
This equipment has been tested and found to
comply within 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 interferences 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. If
operation of this equipment in a residential area
causes harmful interference, the user is required
to correct the interference at their own expense.
See Figure 2-2.

3 Description
This section provides a general description of the
Opticom™ GPS system and a detailed description
of the vehicle equipment.
3.1 Opticom™ GPS System
The Opticom GPS system assists authorized
priority vehicles through signalized
intersections by providing temporary right-ofway through the use of common traffic
controller functions.
The Opticom GPS system consists of the
following matched components:
Vehicle Equipment —
Radio/GPS unit containing a GPS receiver and
a 2.4 GHz transceiver
Radio/GPS antenna
Control unit
Intersection Equipment —
Radio/GPS unit containing a GPS receiver
with antenna and a 2.4 GHz transceiver with
antenna
Or Radio/GPS unit containing a GPS receiver
and a 2.4 GHz spread spectrum transceiver
with a separate Radio/GPS antenna
Phase Selector
Card Rack/Input File
Auxiliary Interface Panel
The vehicle equipment is mounted on the priority
vehicle. Its GPS receiver acquires position
information from the constellation of GPS
satellites. This information is used to compute the
location, speed, and heading of the vehicle. This
information, along with a priority request and the
state of the vehicle’s turn signal, is broadcast using
the 2.4 GHz transceiver.
The intersection equipment receives the radio
transmission from the vehicle equipment. The
intersection equipment then compares the
information being received from the vehicle to
the parameters stored in the intersection
equipment’s memory. If the vehicle is heading
toward the intersection in a predefined
approach corridor, is requesting preemption and
has met all other programmed parameters, the
corresponding phase selector output is
activated. This output is connected to the traffic
controller preemption input. When activated,
the controller cycles to grant a green light to the
requesting vehicle or holds the green allowing
the vehicle to pass through the intersection.
The card rack/input file provides the power and
logic wiring for the phase selector, which plugs
directly into a slot in the unit.
The auxiliary interface panel provides additional
connections for monitoring green phases and
also provides additional priority control outputs.
The green sense harness can be used to provide
additional connections for monitoring green
phases when the auxiliary interface panel is not
required.
