What is Millennium?
Requirements and safety regulations
is an industrial sound system that allows to control and distribute intercommunication and public-address system along an installation.
The system layout can be configured either in centralized or decentralized mode, and even mixed as the most versatile way, open to the needs of an installation.
MILLENNIUM is divided into two product ranges:
• For 2+1 zones: for covering up to 3 zones, designed and planned for small shops and establishments.
• For larger-sized facilities, which allow to control from 1 to 127 zones independently, from one to several control points and with a wide range of possibilities.
Installation philosophy
MILLENNIUM architecture is mainly based on one 9-wire bus (15 Vdc power supply included), with 4 independent audio-programmes, messages and digital
communication between its units and modules. We can add as many units/modules as desired, connected in parallel and including power supply units distributed
along the installation.
Once this concept is known, the installation can be set up in different ways: centralized or decentralized power supply, or a combination or both.
Centralized installation
In a centralized power distribution, the system management units as well as control and amplifier units are located in the same place to distribute the amplified
sound signal to the speakers in each zone. This type of distribution can be of low or high impedance. Low impedance output will be used when the loudspeakers
are relatively close to the centralization point. Transmitted power is low due to audio signal reduction along the bus-wire length. If opposite, that is remote
loudspeakers, transmitted power is high and then a high impedance installation would be advisable.
A centralized installation has all its amplifiers in the same place, however, control from other places through any
1202 control unit is allowed.
Decentralized installation
A decentralized installation is based on the audio and digital control distribution with low level signals (with less reduction or loss along the wires, which guarantees
a higher quality signal). This type of installation has the advantage of being controlled from any or several control points.
A decentralized installation must have at least one amplifier in each place where we want the sound to reach for the loudspeakers situated there. Their regulation
can be made by using local control units, from any 1202 control console available along the installation as well as from a computer ( 0801 software). Tha
amplifier/s and loudspeakers in each zone can play the audio programes (music and messages) shared by the whole installation as well as autonomous audio
signals generated in such zone, like microphones or audiovisual equipments on special occasions, to make the most of the electroacoustic resources.
Mixed installation
The mixed installation is the ideal installation as it allows both previous configurations, depending on the needs of the installation.
Is in this situation when
MILLENNIUM enables us to combine installation areas with centralized power and other areas with decentralized power distribution.
We only have to install the appropiate MILLENNIUM units/modules, all of them interconnected through a general bus line, usually called " GENERAL LINE " so
that we can control and amplify as needed.
All the MILLENNIUM electrical elements meet the electrical safety regulations and electromagnetic compatibility (CEM ) according to the folowing guidelines:
- 73/23 EEC, modification 93/68 EEC. Low voltage guideline
- 89/366/EEC, modification 92/31/EEC. EMC guideline
All the sound system installation devices must be connected to the same funcional 230 V~ circuit, and this will be of the exclusive use of such installation,
therefore no other electrical devices that are not part of the installation should be connected.
The mains wires section and acceptable voltage loss, etc, will be established according to the R.E.B.T. 02 criteria (UNE EN 24060).
Mains circuit will go from the electrical general panel through its respective control and protection devices (PIA), as well as overvoltage protection devices.
Regarding the
MILLENNIUM sound signal conductors and wires (audio, digital data and power supply) those indicated by the manufacturer or any other that
meets at least the same constructive specifications will be used.
Conductors supplied by
EGi 1507LH , 1507.1LH and CML100V to install MILLENNIUM devices comply with intrinsic safety requirements: 750 V isolation, flame-
resistant (UNE EN 50265 and UNE EN 50266), toxic and halogen fumes reduced emission (UNE EN 50267) and/or low fumes emission (UNE EN 50268).
