Praesideo components |
|
The simple system philosophy
behind Praesideo is demonstrated by the amount and total
inter-compatibility of system elements.
By combing multiple functions in the units, the number of different
system elements is kept to a minimum, thus simplifying both
ordering and installations. Putting together a top class public
address and emergency sound system has never been this easy. |

| This is a special cable with
2 plastic fibres for data communication and 2 copper cores for
the power supply. The cable is supplied with the network connectors
fitted. This cable can be used to connect the network controller
to power amplifiers, audio expanders, call stations etc. Cables
are available in various lengths. All cable assemblies are supplied
with pre-terminated connectors (LBB 4417/00) with the exception
of the 100m cable LBB 4416/00. These cables are used for distances
of up to 50m. For cable distances of more than 50m, a fibre
interface unit LBB 4414/00 is used to convert to glass fibre.

The Network Splitter, LBB
4410/00 can be inserted anywhere in the Praesideo system cabling.
Allows extra branches in the network to be created.
The
network splitter also has a provision to connect a 48Volt DC
supply which can be used if additional power is required.
Fibre Interface ensures optimum
signal integrity for longer cable interconnections. It also
conveys signals from plastic to glass fibre cabling or visa
versa. Plastic
fibre is used to connect Praesideo components for distances
of less than 50m. For distances of more than 50m, a glass fibre
optic cable is used and the fibre interface unit LBB 4414/00
is used to convert from plastic fibre to glass fibre.
