BOSCH PRS-CSR Call Station Remote

BOSCH PRS-CSR Call Station Remote

The PRS-CSR is a professionally designed call station that comes along with the same functionality as the basic call station, LBB 4430/00, but it comes using CAT-5 cable intended for its connection to the Praesideo network. It comes connecting, one-to-one, to the call station interface, PRS-CSI, which is part of the Praesideo optical network. The CAT-5 cable, carrying digital audio and control data, are possible to be as long as 1 km. The length of the CAT-5 cable is not a part of the Praesideo optical network length. This considerably is increasing the overall possible length of the optical network.

The PRS-CSR are capable to be extended along with up to 16 keypads (LBB 4432/00 or LBB 4434/00), each comes along with eight programmable keys. Extension with a numeric keypad (PRS-CSNKP) is also possible.

Functions

The call station comes with a cardioid, supervised microphone on a gooseneck stem that comes along with good speech intelligibility. A limiter and a speech filter are improving the intelligibility and is preventing the clipping of the audio. It comes along with a volume control for the monitoring speaker and the headset. During the time it is playing a chime or a pre-recorded message, the call station is activating its speaker. By the time a headset is connected, it comes replacing the microphone and speaker.

The remote call station is connecting with the use of a CAT-5 cable to an 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 fail-safe operation. Even if the Praesideo network controller fails, the call station is still able to put through emergency calls.
