3 Preparation & Note for the System Installation

3.1 Preparation for System Installation

 Please check whether the system capacity is suitable.

 Please prepare the necessary wires and instruments for installation.

 Please carefully read this manual before installation and follow up the procedures of

installation on this manual.

3.2 Special Requirements for Installation Environment

 Input AC Voltage: AC220V±15 

 Wiring Requirements

CO Line: 2-conductor wiring

SLT Extension: 2-conductor wiring

External Music Source: 2-conductor wiring

3.3 Equipment Remarks

 The system should be installed at a clean, dry and secure place, 10 centimeters above the

ground to avoid the vibration.

 The location must have adequate ventilation and a temperature range between

-10~40 with a ≤85% non-condensing relative humidity.

 The installation site should have sufficient room to mount the System along with the

necessary connecting blocks and ancillary equipment. The installation site should not be at

the area with static electricity (e.g. Dry copiers), or vibration (e.g. Heavy duty machinery).

 This system must use the independent power input. The power should better not share

with other power-consumption equipment, for example: huge power-consumption machine

and be controlled directly by main switch. In addition, the location must be far away from

high frequency & noise soundings to avoid the interference from radiation EMI.

 Voltage Stabilizer is recommended if the electricity supply is not so stable.

 Please use the lightening-protection equipment to guarantee system’s stability.

 Suggest using twist wires for CO line & station line to avoid noise and interruption.

 SLT wiring must be away from some other disturbance (e.g.radio wave). Otherwise a

separate earth is required in addition to the third earth wire on the AC circuit.

3.4 Safety Warnings

 Avoid using the device in areas where wireless transmission equipment is prohibited such

as hospitals, health care facilities and on board aircraft.

 Avoid using the device in petrol stations, bunkers or places of chemical storage.
