Bosch PRA-CSLD Desktop LCD Call Station

The Bosch PRA-CSLD 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 Bosch PRA-CSLD 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.

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.
• The 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).
• 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.
