Desktop LCD call station

• Desktop housing with gooseneck microphone
• 4.3″ full‑color capacitive touch screen
• Graphical user interface for optimum user guidance and feedback
• Status and fault indicators for voice alarm purposes
• Dual OMNEO IP‑network connection and redundant Power over Ethernet

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. The housing is fit for surface mounting and flush mounting. 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. Add up to four PRA-CSE call station extensions for zone selection and other functions. Without extensions the call station can only be used with a pre‑configured zone selection.

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.

Business operation

• Full color 4.3″ capacitive touch screen with intuitive function menu navigation provides guidance and feedback during the process of live announcements, pre‑recorded messages and music control. Successful broadcast of announcements/messages and changes to the background music settings are clearly indicated.
• Press‑to‑talk button gives tactile feedback and is recessed to prevent accidental use.
• Built‑in monitor loudspeaker with volume control.
• Local audio line input (with stereo to mono conversion) for connecting an external audio source. The audio channel will be available on the network and can be played in any loudspeaker zone.
• Connection of up to four PRA-CSE extensions, each with twelve buttons. The buttons can be configured for various functions, but they are especially useful for zone selection, giving a clear overview of accessible zones and the LED indicators for each button show the status of the respective zone (like being selected, occupied or at fault).
• A User number and PIN code can protect the device in public places against unauthorized access.
• If the call station is not used for a while, it will switch to sleep mode to save energy. It will immediately wake up when the screen, or a button, is touched.

Emergency operation

• The call station fully complies to the standards for voice alarm applications when the firemen’s user interface is configured and at least one PRA-CSE is connected to it.
• All critical alarm functions are accessible via buttons for operators wearing gloves. The 4.3″ screen gives feedback on the system status.
• Each of the two RJ45 network connectors accept PoE to power the call station. This provides fail‑safe network connection redundancy, as one connection is sufficient for full operation.
• Supervision of all critical elements; the audio path is supervised, as well as the communication to the network.
