2Safety Information
We provide important safety information and
warnings to assist you in understanding and
avoiding potential harm to yourself, and possible
damage to equipment, during the installation of
the Opticom™ Infrared System equipment.
Although we have included many potential
hazards you may encounter during the installation
of this equipment, we cannot predict all of the
possible hazards and this list should not be a
substitute for your judgment and experience.
Please read and observe all safety information
and instructions in this manual before installing
the system equipment. Also, save this
installation manual and keep it near the
equipment.
If you are unsure about any part of this installation
or of the potential hazards discussed, please
contact your supervisor immediately.
2.1 Intended Use
The system is intended to assist authorized
priority vehicles through signalized intersections
by providing temporary right-of-way through
vehicle operator interface to the system and
through the use of common traffic controller
functions.
2.2 Technical Support
If you have questions about the system, its use, or
operation, please contact your dealer or call the
Global Traffic Technologies Technical Service
department at 1-800-258-4610.

Please read all messages before proceeding with
the installation.
Safety Message Format
Safety messages are designed to alert you to
potential hazards that can cause personal injury
to you or others. They can also indicate the
possibility of property damage.
Each safety message box contains a safety alert
symbol ( ); one of three signal words:
DANGER, WARNING, or CAUTION; and a safety
message.
The signal words and symbols, and their
meanings, are shown below:
DANGER
The safety message is in this box.
DANGER means you and/or someone else WILL

In addition to the symbols and words explained
above, each safety message identifies the hazard,
describes what you can and should do to avoid
the risk of exposure to the hazard, and tells the
probable consequences of not avoiding the
hazard.

2.3.2 Safety Label Format
We include safety labels on the devices to help
you protect your safety and the safety of others.
Safety labels are designed to alert you to potential
hazards associated with a piece of equipment that

We consider safety labels to be an important part
of all devices and they should be replaced
immediately if they become hard to read.
If any of the safety labels are missing, or cannot
be read, please contact your dealer or the GTT
repair department for a replacement.
2.4 Safety Message Contained in this
Manual
The following safety message appears in this
manual:
WARNING
This procedure may expose you to AC
voltage and the risk of electric shock or

use accepted and recognized safety
precautions to avoid exposure to the risk of
electric shock or electrocution. Electric
shock may cause sever injury or death.
2.5 Safety Label Location

2.6 Safety Considerations
Please consider the following safety issues before
beginning the installation.
Although we have provided 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.
Work Zone Traffic Control
Proper control of vehicle traffic is important
during many procedures. When you switch the
traffic controller to and from the flash mode we
recommend that you have people trained in
manual traffic control, such as police officers,
assist you.
When you install devices that require you to
position vehicles, equipment, or people in or near
the roadway; it is important that you use
appropriate work zone traffic control techniques,
equipment, and procedures. Sometimes you may
have to work on or near the roadway and these
same techniques, equipment, and procedures
should be used for your protection.
If you are unsure of which procedures are
recommended or appropriate for the job, ask your
supervisor or foreman.
2.6.3 Electrical Shock
The possibility of electrical shock exists when
installing Opticom system equipment, since
connections must be made to open terminals
within the traffic control cabinet which may have
120 VAC present. Follow proper work
procedures and read and understand the safety
messages in this manual.
As a trained installer of electrical equipment you
are aware of the dangers associated with the
installation of electrical devices. Always be sure
that the power to the equipment, and all
associated equipment, is turned off before
beginning any procedure. 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.
2.6.2
2.7 Disposal of Device
Please dispose of the device in accordance with
all local, state, and federal laws and regulations.

3Description
The Model 760 card rack is usually required in
N.E.M.A.1type controller installations.
The Model 760 card rack is also used when input
file space is not available for Type 1702controller
installations.
Card slot X1 in the Model 760 card rack is
dedicated to Opticom phase selectors and
discriminators. The X1 edge connector is wired
to connector J1 on the card rack front panel. The
card rack is connected to the traffic controller by
a 9-pin wiring harness. The wiring harness
provides inputs and outputs to the traffic
controller system hardware.
NOTE
Illustrations and connections to the traffic
controller may not be exactly as shown or
described in this manual. Refer to the
controller wiring diagram for correct
terminal connections.

the card rack and the installation procedures
are complete. For information on the phase
selector or discriminator installation, see the
Installation Instructions manual for the
Model 752/754 and 752N/754N phase
selectors, or the Model 452/454 and
252/254 discriminators.
3. Route the 9-pin harness wires to their
terminals.

months to ensure that it functions to your
specifications and requirements.
•Intersection systems should be tested with
known good emitter systems.
•Emitter systems should be tested with known
good intersection systems.
•You should develop a test plan that fits your
department’s operations and meets the needs
of your system.
