Caution: The ADPRO FastTrace is a Class 1 electrical product and must always be
connected to a grounded power outlet.
Always ensure that ADPRO FastTrace is installed adjacent to a grounded power
outlet.
2.2.1 Power Conditioners and Surge Arresters
The use of an Uninterruptible Power Supply (UPS) should be considered in situations where the
mains power is unreliable. A good UPS has the ability to remove interference, sags, and power
surges that can cause false alarms, equipment failure or even terminal damage. UPS are used
effectively on all major computer installations and the microelectronics used in many video and
alarm systems (including FastTrace) are similar, both in their functionality, and their susceptibility
to ‘dirty’ mains power.
Power line conditioners or surge arresters can help prevent mains distortion of voltage, current,
and frequency caused by load switching, large electric motors, and lightning. These distortions
can cause unreliable operation, false alarms, and equipment failure, damage or even total
destruction.
2.2.2 Interference Caused by Ground Loops
In some installations, where cameras or monitors are located at a distance from the FastTrace
rack, considerable ground loop currents can be generated and may cause interference.
Supplying power to different components of the FastTrace system may also cause ground loop
currents. For example, cameras, monitors and the FastTrace chassis may receive power from
different phases of a multi-phase supply. Wherever possible, source power to all components of
the system from a common phase of the supply.
Where ground loop currents cause a problem in a FastTrace installation, the installer may reduce
the effect by installing a video isolation transformer on each video channel affected.
2.3 System Wiring Considerations
2.3.1 Electromagnetic Compatibility (EMC) Issues and
Instructions
When a FastTrace system is installed in accordance with the recommendations and procedures
in this manual, it will meet the EMC requirements of:
• EN 55022 / AS3548 Class A, and FCC Part 15 Class A digital devices in respect to
emissions, and
• EN 50130-4 Alarm Systems Immunity.
To ensure EMC compliance for your system installation, make sure of the following:
• CAT-5 Unshielded Twisted Pair (UTP) Data Cable is used for the Network port connection,
• RG-59 coaxial 75 ohm Video cable is used for all composite video connections and the
cables are terminated with 75 ohm BNC connectors, and
• Where possible, all cables should be shielded (single or dual) twisted pair and the shield
itself, along with the associated drain wire, terminated at the FastTrace with a connection to
the chassis.
