The PRA-CSLW is a call station for use in PRAESENSA
Public Address and Voice Alarm systems.
It is easy to install and configure, but especially easy
to operate because of its touch screen LCD, providing
clear user feedback about setting up a call and
monitoring its progress, or controlling back ground
music.
The call station allows for straightforward positioning
because it only requires a connection to an OMNEO
IP‑network with Power over Ethernet (PoE) for
communication and power supply combined.
It can be configured for use as business call station,
but also as emergency call station.
The stylish design uses a heavy metal base with a
recessed press‑to‑talk button and provides a
hand‑held omni‑directional microphone to eliminate
the proximity effect which creates a boomy sound
when a user speaks close to the microphone. It has a
built‑in loudspeaker for call monitoring and a socket to
connect a local background music source. It can be
easily installed in a wall mount cabinet or flush
mounted on a panel.
The 4.3" high‑resolution full‑color capacitive touch
screen gives the operator optimum control and
feedback at all times.
It can be extended with up to four PRA-CSE keypads,
each with twelve configurable buttons.
Functions
IP‑network connection
• Direct connection to the IP‑network. One standard
CAT5e cable is sufficient for Power over Ethernet,
audio and control.
• For dual redundancy of network and power
connection, a second CAT5e cable can be connected.
• Integrated network switch with two OMNEO ports
allows for loop-through connections to adjacent
devices (that provide PoE). Rapid Spanning Tree
Protocol (RSTP) is supported to enable recovery from
failing network links.
Business operation
• Full color 4.3" capacitive touch screen with intuitive
function menu navigation provides guidance and
feedback during the process of live announcements,
pre‑recorded messages and music control. Successful
broadcast of announcements/messages and changes
to the background music settings are clearly
indicated.
• Press‑to‑talk switch on hand‑held microphone.
• Built‑in monitor loudspeaker with volume control.

• Local audio line input (with stereo to mono
conversion) for connecting an external audio source.
The audio channel will be available on the network
and can be played in any loudspeaker zone.
• Connection of up to four PRA-CSE extensions, each
with twelve buttons. The buttons can be configured
for various functions, but they are especially useful
for zone selection, giving a clear overview of
accessible zones and the LED indicators for each
button show the status of the respective zone (like
being selected, occupied or at fault).
• If the call station is not used for a while, it will switch
to sleep mode to save energy. It will immediately
wake up when the screen, or a button, is touched.
Emergency operation
• The call station fully complies to the standards for
voice alarm applications when the firemen's user
interface is configured and at least one PRA-CSE is
connected to it.
• All critical alarm functions are accessible via buttons
for operators wearing gloves. The 4.3" screen gives
feedback on the system status.
• Each of the two RJ45 network connectors accept PoE
to power the call station. This provides fail‑safe
network connection redundancy, as one connection is
sufficient for full operation.
• Supervision of all critical elements; the audio path is
supervised, as well as the communication to the
network.

Architects & Engineers specification - PRA-CSLW
The IP‑networked wallmount call station shall be
designed exclusively for use with Bosch PRAESENSA
systems. The wallmount call station shall provide an
interface for control data and multi‑channel digital
audio over OMNEO using dual Ethernet ports for
redundant network connection, supporting RSTP and
loop-through cabling. It shall receive Power over
Ethernet (PoE) via either one or both network
connections. The wallmount call station shall provide a
backlit full‑color capacitive touch panel LCD as user
interface for business and evacuation purposes. The
wallmount call station shall accept up to four optional
call station extensions, each offering 12 configurable
buttons for zone selection and other purposes. It shall
provide control and routing of live speech calls, stored
messages and music with volume control per zone.
The wallmount call station shall have a hand‑held
omnidirectional microphone for live calls and a 3.5 mm
jack line level input for background music, and provide
software-configurable signal processing including
sensitivity control, parametric equalization and
limiting. The wallmount call station shall be certified
for EN 54‑16 and ISO 7240‑16, marked for CE and be
compliant with the RoHS directive. Warranty shall be
three years minimum. The wallmount call station shall
be a Bosch PRA-CSLW.
