2.6
Evacuation compliance
The Praesideo range of equipment complies with the
various emergency standards which are applicable all
over the world. The network controller is capable of
monitoring all the units in the system, from the
microphone capsule of the call station to the
loudspeaker line. A built-in memory stores the last
200 fault messages. Any fault is reported back to the
network controller. The system also meets emergency
requirements for emergency call stations. The highly
open system concept, with the possibility for large
numbers of control inputs and outputs satisfies even
difficult emergency requirements.
2.7
External interfaces
The interfaces to the system can be audio, control input
or Ethernet. The Ethernet interface is provided at the
network controller. The audio and control inputs can be
anywhere in the system, for example at the power
amplifier, audio expander or network controller.
The system also accepts contact closures via the control
inputs. The configuration allows the user to configure
the input to initiate the desired actions in the system.
The flexibility to route any input from one system unit
to another makes it possible to use the Praesideo range
of products or a wide range of public address and
emergency sound system applications.
2.8
Reduced installation costs
The Praesideo architecture uses the daisy chain
principle with the possibility of branching for both data
and audio signals. This makes the system wiring very
cost-effective, using 2 fiber cores for data and audio
communication and a copper wire pair to supply power
to the units. Power supply for the system units can be
provided locally if the distances are very long.
Combining various functions in a single unit also makes
equipment more cost-effective than systems in which
separate units have to be purchased for all the specific
functions. This combination of functions also saves lot of
rack space and further reduces installation costs.

2.9
High system flexibility
The Praesideo system is a highly versatile system which
gives the user a high degree of flexibility in the number
of zones, call stations, audio inputs and outputs, control
inputs and outputs, etc.
