Safety – 3
2Safety
We include important safety information and warnings to help you understand and avoid potential
harm to yourself, and possible damage to the equipment, during the installation of the C924X vehicle
detectors. Although we have included potential hazards that 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.
NOTE: Please read and observe all safety information and instructions in this manual before
installing the system 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 Canoga™ Traffic Sensing System, including vehicle detector(s), used with C900 Configuration
Software (C900-CS) is intended to provide traffic measurement and vehicle detection information for
use in Intelligent Transportation Systems and Advanced Traffic Management Systems.
The Canoga Traffic Sensing System consists of the C924X vehicle detectors, the C900-CS configuration
software and the GTT 701 or 702 Microloops™. The vehicle detectors may also be connected to
standard inductive loops.
2.2 Technical Support
If you have any questions about the system, its use, or operation, please call the GTT Technical
Service Department at 1-800-258-4610 or [phone] (Worldwide Technical Service).
2.3 Safety Messages
We include safety messages in this manual to help protect your safety and the safety of others. This
section contains important information to help you recognize and understand these safety messages.
NOTE: Please read these messages before proceeding with the installation.
2.4 Safety Considerations
Please consider the following safety issues before beginning the installation.
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.
2.4.1 Personal Safety Equipment & 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.

2.4.2 Work Zone Traffic Control
Proper control of vehicle traffic is important during many procedures. When necessary, 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.
2.4.3 Electric Shock
The possibility of electrical shock exists when installing Canoga™ C924X vehicle detectors if they are
not installed properly. 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
installation of electrical devices. Always be sure that the power to the equipment, and all associated
equipment, is 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 procedures are recommended for the job, ask your supervisor or foreman.
2.5 Disposal of Device
Please dispose of the device in accordance with all local government laws and regulations.
2.6 Regulatory Requirements Conformance
Canoga C924X vehicle detectors meet US FCC Part 15, Subpart B and Canada ICES-003, Issue 5: 2012
