u Stable metal enclosure

The PRS‑CSRM is a module with the same functionality

as the remote call station, PRS‑CSR, but without its

housing and other components. It is a building block

to make custom call stations or panels. It connects via

a CAT‑5 cable, 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 CAT‑5 cable

does not contribute to the Praesideo optical network

length. This considerably increases the overall possible

length of the network.

The PRS‑CSRM can be extended with up to 16

keypads (LBB 4432/00 or PRS‑CSKPM), each with

eight configurable keys. Extension with a numeric

keypad (PRS‑CSNKP) is also possible.

Functions

The call station module has a connection for a

supervised microphone. 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, this can be monitored via a

connected loudspeaker or headphone. When a

headset is connected, it replaces the microphone and

speaker. The call station has its own DSP for audio

processing functions, including sensitivity adjustment,

limiting, and parametric equalization.

The module 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.

Call station keypads can connect to the module via a

serial communication link. The module provides the

power for the keypads.

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.

Controls and indicators

These must be supplied by the installer.
