  • Compatible with STENTOFON AlphaCom, STENTOFON Pulse and iPBXs (SIP)
  • Designed to deliver CCoIP® - Critical Communication over IP
  • Ideal for Micro Zone PA and systems that require a limited number of speakers
  • Each speaker is individually addressable
  • Ideal for speakers installed in remote locations, e.g. roads and railways
  • IP-67 housing
  • Remote software upgrade, configuration, and monitoring
  • Integrated data switch with advanced networking and security functions
  • Relay output for remote control, e.g. doors, signal lamps, gates
  • Powered from the IP network cable using Power over Ethernet (PoE)
  • Superb audio quality – high bandwidth codec and adaptive jitter filter.


The IP speaker supports open standards and is compatible with STENTOFON AlphaCom, STENTOFON Pulse and iPBX's using SIP technology. When working in AlphaCom mode, the IP speaker supports special services only available using the STENTOFON CCoIP protocol, AlphaCom server. Examples of services are emergency broadcast with volume override, CCTV integration, call priority, and AlphaNet multisite networking and STENTOFON event scripting.

With IP, the system is able to monitor and address each speaker individually. By moving the amplifier from a central unit out to the speaker itself, the need for a central amplifier unit with conventional speaker loops is eliminated. This makes the system highly scalable, and adding another speaker is very easy.

Even though conventional speaker loops are not used, the speakers can still be divided into groups. These zones can now extend over networks or span the internet.

The IP ceiling loudspeaker has an integrated managed data switch providing advanced networking and security features. The integrated switch provides support for:

  • Protection from unwanted access
  • Quality of Service (QoS) by managing data traffic
  • Increased system availability through redundant LAN infrastructure
  • Cost efficient installation by providing shared network connections

To provide maximum availability, the speaker comes with advanced supervision functions. The speaker line test will detect if there are any faults in the network or speaker electronics. The status of the speaker is reported to AlphaWeb as well as to 3rd party management systems using SNMP, Syslog or OPC.

The speaker has a built-in web server for status information, control, and upgrade. It is easy to install and maintain and all broadcasts are logged in detailed reports using STENTOFON AlphaCom.

The IP Horn loudspeaker is ideal for “Micro Zone PA”, e.g. when you only want to address a specific area such as a guard room, elevator, patient waiting room etc.
