PART 1. SITE REQUIREMENTS
When planning the installation of the DS 616
,
choose a site that meets the following
requirements:
!
Select a location for the key service unit (KSU) that has enough space for easy
installation and adequate lighting
!
Select a location that will minimize cable lengths.
See the Cable Requirements table
!
The equipment should not be exposed to direct sunlight, corrosive fumes, dust,
constant vibration or strong magnetic fields such as those generated by motors and
copy machines.
!
A direct commercial AC power outlet is required. Do not use extension cords.
Preferably, a dedicated circuit should be used to minimize the risk of other electrical
equipment being connected that could adversely affect system operation.
!
Ensure that all wires and cables going to and coming from the KSU are properly
routed. Do not cross fluorescent lights or run parallel with AC wires.
!
The equipment must be located in an environment that will maintain a temperature
range of 32°–104°F (0°–40°C) and a humidity range of 10%–90% non-condensing.
!
Allow at least 6" clearance on both sides and 6" clearance on top of the KSU to
ensure proper ventilation.
!
Do not install in close proximity to a fire sprinkler head or other sources of water.
Meeting these requirements will help to ensure proper performance and greater life
expectancy of the system.
