PRA-CSLW Wallmount LCD call station
www.boschsecurity.com
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 uses a heavy metal base with a recessed press to talk button and provides a hand held omni directional microphone to eliminate the proximity effect which creates a boomy sound when a user speaks close to the microphone. It has a built in loudspeaker for call monitoring and a socket to connect a local background music source. It can be easily installed in a wall mount cabinet or flush mounted on a panel.
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.
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 switch on hand held microphone.
2 | PRA-CSLW Wallmount LCD call station
•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).
•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.
