Praesideo Call Station Remote Module

www.boschsecurity.com

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.

uUp to 1 km from Praesideo optical network

uConnection for keypads

uConnection for transducers and status LEDs

uStable metal enclosure

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.
