Installation
1 - 4 ADPRO FastTrace, Issue 5
• Environment - Choose an inside location that is cool and dry. Do not mount the ADPRO FastTrace
anywhere near machinery that generates heat, toxic fumes and dust. Do not mount the ADPRO FastTrace
in close proximity to sources of radio frequency or other electromagnetic radiation. These include radio
transmitters (both fixed and portable), electric motors, refrigeration or air conditioning systems and high
power or multiphase switching equipment.
1.3 General Power Requirements
Any AC supply connected to the ADPRO FastTrace should be:
• Provided from a reliable electric supply company - typically this means that the power is not disconnected
(or lost) for any more than eight (8) hours at a time in any thirty six (36) hour period and infrequently in a
single year
• Provided from a supply bus within the protected premises that is not isolated at night (or out of hours) or
time switched. The supply should be free from voltage spikes or current surges (connected to high power
switching equipment or electric motors)
• Supplied directly to the ADPRO FastTrace via circuits that cannot be switched off, intentionally or
accidentally
Always consider local regulations, standards, and guidelines for mains power connected systems.
1.3.1 Power Conditioners and Surge Arresters
The use of an Uninterruptable 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’s are used effectively on all major computer installations and the
microelectronics used in many video and alarm systems (including ADPRO 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.
1.3.2 Interference Caused by Ground Loops
In some installations, where cameras or monitors are located at a distance from the ADPRO FastTrace rack,
considerable ground loop currents can be generated and may cause interference.
Supplying power to different components of the ADPRO FastTrace system may also cause ground loop currents. For
example, cameras, monitors and the ADPRO 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 an ADPRO FastTrace installation, the installer may reduce the effect
by installing a video isolation transformer on each video channel affected.
