9.0 CABLING

9.1 Stations

In order to guarantee a better availability and to avoid interruptions, all intercom stations shall be connected to the central processing unit in a star-method.

For a digital system in general, the two/four wire technique is required. The power, speech and data between the intercom stations and the central processing unit are transmitted via these two/four wires. A standard twisted pair shielded telephone cable has to be used.

The stations of series “Access Panel” and the “Remote PA units” can use existing KJO Transmission link for the connection to central processing unit.

9.2 Connections between central systems

Connection between central nodes can be established by Ethernet or by dedicated fibre optic (Single Mode) cable connection, depending on distance and availability.

The network topology can be realized in star, ring or mixed structure. Existing Port in the OTN System can be used.

9.3 Loudspeakers

Loudspeakers are to be connected in speaker lines with 70-100 V technologies of 250 W maximum loads per line. Standard power cables can be used (e.g. 3 x 2.5mm²). The cable loss has to be considered depending on the loudspeaker cable length. Also site requirements for mechanical ruggedness have to be considered.
