12.1 Introduction
This call station for use in PRAESENSA Public Address and Voice Alarm systems is easy to
install and intuitive to operate because of its touch screen LCD, providing clear user feedback
about setting up a call and monitoring its progress, or controlling back ground music.
The call station allows for positioning without much effort, because it only requires a
connection to an OMNEO IP‑network with Power over Ethernet (PoE) for communication and
power supply combined.
It can be configured for use as business call station, but also as emergency call station.
The stylish design incorporates a supervised microphone, an internal monitor loudspeaker and
a socket to insert a local audio source for background music.
The 4.3" high‑resolution full‑color capacitive touch screen gives the operator optimum control
and feedback at all times.
Every call station must have at least one PRA-CSE call station extension for zone selection,
with a maximum of four extensions.
12.2 Functions
IP‑network connection
– Direct connection to the IP‑network. One shielded CAT5e cable is sufficient for Power
over Ethernet, audio and control.
– For dual redundancy of network and power connection, a second shielded CAT5e cable
can be connected.
– Integrated network switch with two OMNEO ports allows for loop-through connections to
adjacent devices (at least one must provide PoE). Rapid Spanning Tree Protocol (RSTP)
is supported to enable recovery from failing network links.
