22.3.3 Connecting a power supply

Normally, the call station interface and the remote call station are powered from the Praesideo network. It is also possible to power the remote call station and the call station interface from external power supplies. For example, when:

•The call station interface is connected to a fiber interface without external power supply.

•The cable between the remote call station and call station interface is long and many call station keypads are connected to the remote call station.

The following power concepts are supported:

•Concept I

The call station interface takes the DC power from the Praesideo network to power itself and the connected remote call station. When the voltage on the Praesideo network drops below 18 V(DC), the call station interface and the remote call station take the DC power from the external power supply of the call station interface. The Jumper settings are described in figure 22.4 and table 22.1.

•Concept II

The call station interface takes the DC power from the Praesideo network to power itself and the connected remote call station. When the voltage on the Praesideo network drops below 18 V(DC), the call station interface and the remote call station take the DC power from the external power supply of the remote call station. The external power supply of the remote call station is the back-up power supply for both the remote call station and the call station interface. The Jumper settings are described in figure

22.4and table 22.1.

•Concept III

The call station interface takes the DC power from the Praesideo network to power itself. When the voltage on the Praesideo network drops below 18 V(DC), the call station interface takes the DC power from its external power supply. In this concept, the remote call station always has its own external power supply. The Jumper settings are described in figure

22.4and table 22.1.

The remote call station and the call station interface are delivered with a separate Kycon KPP4-P connector to connect external power supplies.

Note

The pin numbers are also indicated on the inside of the connector. For detailed connector assembly instructions, see appendix B.

Warning

For safety reasons, you must use a current limited external power supply complying with the 60065 standard for audio/video usage or equivalent, with a maximum output current of 5A, or you must use an external fuse (5A max, slow) in the wiring to the Kycon KPP-4P connector.

For application in emergency sound systems in Europe, the installer must use a power supply with EN54-4 certification.

Caution

For USA: only use a power supply of the type Mean Well PLN-30-24, PLN-30-36, PLN-30-48, PLN-60-24, PLN-60-36, PLN-60-48, PLN-100-24, PLN-100-36 or PLN-100-48.

For CANADA: only use a power supply of the type Mean Well PLN-30-24, PLN-30-36, PLN-60-24, PLN-60-36, PLN-100-24 or PLN-100-36.

Other types of power supply are not tested with Praesideo and may cause harm.
