Section II. INSTALLATION
2-4. INTRODUCTION.
This section describes the factors that must be considered in setting up the VR240 in your
facility. Consideration of the appropriate physical location must be made for available power
and audio sources. This includes connecting the unit to power, audio, and ancillary items (i.e.,
clock, label printer).
2-5. PLANNING.
Identify and allocate the inputs to be used as the signal sources for the VR240. Then determine
if you have any channels remaining. If you do, bring them to a convenient patch field as you will
probably find other applications for the VR240 in the future.
Determine the physical location for the VR240. The unit has removable rack mounts and can
be installed in any convenient location that meets the temperature specifications for the unit and
the drives. If you are going to mount it in a rack, do not rely only on the mounts for support – use
a shelf or slide as well. The weight of the unit will exert significant torque on the mounting
hardware. To avoid drive failures and unreliable data transfers the VR240 must be mounted
horizontally not on an angle (such as in some consoles).
Some items to consider:
Convenience
Select a location where changing media can be easily accomplished. If you
do not plan to install remote alarms, locate the VR240 where the media
almost-full, media full, and system fault alarms can be clearly heard.
Security
Do you need to be concerned that someone will want to “destroy the
evidence,” so to speak? If so, how dedicated will that person be? The unit
has security features, but a well-locked door is better!
Power
The Uninterruptable Power Supply will allow the unit to run briefly
(approximately 30 seconds) on batteries while the generator comes up. If you
have a generator, make sure the VR240 will be powered by it. Connect an
inexpensive computer UPS to the logger if outages are frequent or typically
last more than 30 seconds.
Accessibility
Will people continually be using the unit for playback, or will it almost always
be making archival recordings?
Wiring
If almost all the signal sources are in one area, how much wiring do you want
to do to get to the recorder?
Environment
For best reliability, the unit should be placed in a room with comfortable (for
humans) temperature, no extremes of humidity, and as little dust or particulate
matter as possible. A “no smoking” area is preferable.
