32.1Introduction

The exact layout of the Praesideo system depends on the number and type of units that make up the system This chapter contains some easy-to-follow examples of (strongly simplified) Praesideo systems to illustrate the possibilities.

32.2Basic system

See figure 32.1 for an example of a basic system.

In the remainder of this chapter, 'basic system' refers to the system in figure 32.1.

32.3Redundant cabling

The basic system has no redundant cabling. If the cable between the call station basic and the power amplifier breaks, it becomes impossible to broadcast calls or background music. This can be solved by creating a redundant cabled system (see figure 32.2).

Note

In the remainder of this chapter, 'basic redundant system' refers to the system in figure 32.2.

The only difference between the basic system and this redundant cabled basic system is the connection between the power amplifier and the network controller. The equipment now forms a ring. If a cable breaks, the system remains functional.
