Barix Annuncicom 155

Product Description

The Annuncicom Intercom 155 is a rugged, universal IP Audio device, developed to operate within challenging environmental conditions whether outside or in rolling stock.

With an amplified output suitable to drive 5W into an overhead paging or panel speaker, a sensitive microphone input, selector/contact closure inputs and control output the device is equally suitable for paging, intercom, help point and monitoring applications.

A built-in switch provides two 10/100Mbps network interfaces allowing the daisy chaining of devices.

The universal power input (24..48V) is isolated and well protected allowing the use of the device in both telecom as well as rail applications.

The supported codecs (PCM/uLaw/aLaw/MP3) and range of sample rates (8..48kHz) allow the optimization of the audio quality for the application. Up to CD/Hifi quality can be achieved.

Using standard Barix firmware on the Annuncicom 155, the device can operate as a streaming receiver for background music with priority messaging, as a paging or intercom device within a Paging/Intercom system or as a digital message repeater. With the Barix SIP firmware, the device can operate as part of an IP telephony solution, for example, as an intercom panel in parking barriers, toll gates, as a SOS help point, call box etc.

Being fully EN50155 and GL "Brücke" compliant, the device fulfills the stringent requirements to be used in trains, cars,ships and industrial as well as outdoor installations.

With versatile I/O, full multicast support and internal flash memory for audio messages, the device is suitable for many special applications. Most Barix standard applications (such as the SIP firmware, message repeater etc) can be provided as source code for modifications by system integrators or OEMs. Full custom code can easily be written on the devices in the ABCL programming environment.

Applications include:

  • Door intercom, talking over TCP/IP networks
  • Alarming in public infrastructure, e.g. airports
  • Remote paging connectivity via networks
  • Residential intercom with network connectivity
  • Automatic announcement systems
