Why Use an IP Intercom System?
New and emerging IT and presentation technologies enable instructors to help their students comprehend complex concepts
and engage them in the learning process. A lack of sufficient tech support resources often creates obstacles
to the use of advanced presentation technology.
Extron has developed some practical solutions to address this problem. Adding the IP Intercom to an AV system makes
it easy to provide two-way, half-duplex voice communications between classrooms and the central office or instructional
technology help desk. This allows instructors to quickly request assistance and describe the problem they are
IP Intercom Hardware Modules
There are two types of Extron IP Intercom hardware modules:
IPI 100 Series Modules
IPI 100 Series IP Intercom Modules require an IP Intercom-enabled MLC 226 IP MediaLink Controller for operation.
The IPI 101 AAP one-button module and IPI 104 AAP four-button module fit easily into the four-space AAP - Architectural
Adapter Plate opening of the MLC 226 IP AAP MediaLink Controller. The modules can also be placed into a separate
AAP mounting frame, such as the AAP 102. For installation flexibility, IPI 100 Series modules can be positioned
anywhere in the classroom, up to 100 feet (30 meters) away from the MediaLink Controller.
Once installed, the intercom module connects to the MLC 226 IP via an RJ-45 "Intercom" port located on the rear panel
of the controller. This port provides power, control, and audio transport between the two products. The IPI 100
Series use of the existing MLC 226 IP network connection results in a substantial cost savings since there is
no additional expense for installing a second network cable and the number of switch ports is reduced.
IPI 200 Series Modules
The IPI 200 Series IP Intercom Modules are stand-alone, IP-addressable modules that do not require a controller for
operation. Each one has its own RJ-45 Ethernet connector and is powered independently. IPI 200 Series modules
are equipped with Extron IP Link® technology, providing the same powerful AV resource management capabilities
as the MLC 226 IP MediaLink controller.
In the IPI 200 Series, there are one-button and four-button modules and options for mounting in a two-gang wall box
or in any Extron product that accepts a four-space AAP - Architectural Adapter Plate.
Easy Set-up and Configuration
The free IP Intercom HelpDesk software makes it easy to set up, manage, and monitor an IP Intercom system. This software
lets you quickly configure system options and does not require any programming knowledge.
The software also includes a convenient paging capability, allowing the help desk operator to page a single room
or to a group of rooms simultaneously. A line level output is available on the back of each MediaLink Controller
to mix into a local sound system in each room.
Event Call Logging
The IP Intercom System enables real-time audio monitoring by the help desk for any room where an IP Intercom Module
is installed. Using the intuitive IP Intercom HelpDesk software, intercom calls and pages can be logged, and
date/time-stamped on the help desk computer. Event logs can be accessed and archived for record keeping and tracking
The IP Intercom System enhances security operations by allowing audio monitoring for each room. Help desk operators
or other authorized personnel can use the IP Intercom's audio monitoring capability to listen to the activity
in the room, helping them determine if security personnel should be dispatched to investigate. Audio monitoring
can be disabled, if necessary, to comply with local regulations and policies.
The Extron IP Intercom System is perfect for campus-wide AV systems that require internal communications, help desk
support, and security/status monitoring.
