GENERAL DESCRIPTION
......................................................................................................................................................
SCAME, continuing its tradition of servicing Electrical installers through Wholesalers for electrical material is now offering a complete range of components for telephone installations - components that stand alongside the material for TV installations that SCAME has long produced.
These high quality products meet the demands of the modern installer of low voltage installations - the installer who is getting more and more work in telephone and television installations.
COMPONENTS FOR CLASS 5 TRANSMISSION SYSTEM
GENERAL CHARACTERISTICS
......................................................................................................................................................
The SCAME DATATEL-CAT5 Line has been purposely designed to satisfy the requirements of data transmission systems installation. This Line includes diffrerent components, all of them meeting the general requirements of GRADE 5 data transmission systems cable laying.
Free plugs: also available with special "insert" to allow an easy alignment during cabling.
Wall telephone outlets: provided with terminals identification label, according to EIA TIA 565/A and /B Standards; cabling procedure with no need of tools. Shuttered or unshuttered types are available.
Shielding: metal sheating for cables, plugs or outlets preventing signal interference.
REFERENCE STANDARDS
......................................................................................................................................................
- ANSI/TIA/EIA-568-A-1995
- ISO/IEC 11801
- EN 50173
EIA TIA 565/A o /B: Standards (the extensions A or B refer to different cabling): this US Standard first intriduced the term "GRADE 5" to classify the cabling transmission features and application fields. Grade 5 equipments are suitable for 100 Mbs up to 100 Mhz
IEC 11801: International Standard for generic cabling. The transmission features are classified according to different CLASSES.
IEC Class 5 corresponds exactly to GRADE 5.
EN 50173: It is very similar to the above mentioned US and International Standards.
CEI 303-14: Italian Reference Number for the European Standard.
COMPONENTS FOR TV INSTALLATIONS
......................................................................................................................................................
Aerial installation is made up of:
- The aerial that receives the audio/video signal;
- The aerial unit for amplifying and mixing the received signal;
- The distribution network that sends the signal to the user's socket;
In addition, an aerial installation can also be:
- a single aerial installation
- a communal aerial installation
The aerial installation can be set up to receive radio signals as well as televisions signal.
SCAME offers a series of accessories for completing the distribution network:
- coaxial plugs and sockets for both surface and flush mounting
- coaxial cable connectors
- cable dividers and junction boxes
REFERENCE STANDARDS
......................................................................................................................................................
- Italian Standard CEI EN 50083
International Standard IEC 60169
TECHNICAL CHARACTERISTICS OF TV PLUGS
......................................................................................................................................................
Direct type (of derivation).
No attenuation (without devices for splitting the signal).
Not technical with terminal resistance.
Not to be connected to other sockets in cascade connection.
COAXIAL USER SOCKETS
......................................................................................................................................................
In order to guarantee the appropriate use of the installations, the plugs, sockets and T.V. outlets should insure the CEI EN 50083 standards.
- Efficient shuttering, which makes T.V., signals immune to electromagnetic emissions present in the environment.
- Avoid undesirable reflections of signals (impendence adaptation).
- Coupling among various outlets or among various connections of plugs.
