The PRS‑CSR is a call station with the same
functionality as the basic call station, LBB 4430/00,
but it uses CAT-5 cable for its connection to the
Praesideo network. It connects, 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, can 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
increases the overall possible length of the optical
network.
The PRS-CSR can be extended with up to 16 keypads
(LBB 4432/00 or LBB 4434/00), each with eight
programmable keys. Extension with a numeric keypad
(PRS‑CSNKP) is also possible.
Functions
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 a 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
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.
