• 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.
