Bosch PRS-CSR Call Station Remote Specs: The call station has a cardioid, supervised microphone on a gooseneck stem with good speech intelligibility. A limiter and a speech filter improve intelligibility and prevent clipping of the audio. It has volume control for the monitoring speaker and the headset. When it plays a chime or a pre-recorded message, the call station activates its speaker. When a headset is connected, it replaces the microphone and speaker. The remote call station connects via a CAT-5 cable to a PRS-CSI unit, which interfaces it to the Praesideo optical network. The call station gets its power from the interface unit via the CAT-5 cable but is also equipped with a local power supply connection for extreme cases with a very long cable and many keypads. Up to 16 call station keypads can connect to the station via a serial communication link. The call station provides the power for the keypads. Up to 224 priorities can be assigned to the call station. All configuration can be done via the Praesideo network controller. The remote call station is fully supervised and supports the fail-safe operation. Even if the Praesideo network controller fails, the call station is still able to put through emergency calls.
