2.6Evacuation 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.

2.7External 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.

2.8Reduced 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.

2.9High 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.
