SAMSUNG DCS 70
INSTALLATION MANUAL
Chapter Two : Site Requirements
The installation site for the Samsung DCS 70 System should meet the following requirements -
• The location for the key service unit (KSU) must provide enough space for easy installation and
have adequate lighting. The Key Service Unit measures 57cm high by 36cm wide by 13cm deep.
• Select a location that will minimize cable lengths. See the maximum cable length limits in Chapter
6.
• The equipment should not be exposed to moisture, direct sunlight, corrosive fumes, dust, constant
vibration or strong magnetic fields such as those generated by motors and copy machines.
• A single phase, correctly earthed, 240V, 10Amp, 50Hz, AC General Purpose Outlet (GPO) must
be provided within two metres of the KSU. The GPO must be easily accessible and kept clear of
obstructions. Extension cords must not be used. A dedicated, separately fused 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 cable going to and coming from the KSU are properly routed. The cables
should not cross fluorescent lights or run parallel with AC wires.
• The equipment must be located in an environment that will remain within the Temperature range
of 0 o C to 45 o C and 10% to 95% Relative Humidity, non-condensing.
• Allow at least 30cm clearance on both sides and 30cm clearance on top of the KSU to ensure
proper ventilation. Refer to Figure 2.1
• Do not install the KSU 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.
The DCS 70 System has been designed to be immune to the levels
of interference normally found within residential and commercial
premises (for example, mains dips and breaks, electro-static
discharge, overvoltages and transients, electromagnetic fields).
It is the customer's responsibility to provide an environment for the DCS 70 system, Keysets and
cabling that does not contain excessive sources of interference that could affect the operation of the
systems.
