SAMSUNG Installation
DCS-816 March 1999
1-1
PART 1. SITE REQUIREMENTS
To install the DCS-816 system, choose a site that meets the following requirements.
ü Select a location for the Key Service Unit (KSU) that has enough space for easy installation
and adequate lighting. (KSU dimensions [mm]: 465 (H) x 315 (W) x 120 (D))
ü Select a location that minimises cable lengths. See the Cable Requirements table below.
ü 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.
ü A direct commercial AC power outlet is required. Do not use extension cords. Preferably, a
dedicated circuit should be used to minimise the risk of other electrical equipment being
connected that could adversely affect system operation.
ü 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.
ü The equipment must be located in an environment that will maintain a temperature range of
32°F ~ 104°F (0°C ~ 40°C) and a humidity range of 10% ~ 90% non-condensing.
ü Allow at least 150 mm clearance on both sides and 150 mm clearance on top of the KSU to
ensure proper ventilation.
ü Do not install within a 2-mile radius of broadcasting antenna or 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.
