The Bosch PRA-CSLW 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.
