Overview:
The ICA-202D is the audio heart of integrated services communications systems.
The ICA-202D is designed with the System Integrator in mind. The logic interface will function
well in a simple two-station setup. However, its strength is a robust logic interface that is ideal
for remote control from an external source such as a PLC, or computer, making integration into
larger systems easy.
The ICA-202D has jumpers and digital switches for application configuration. Once the settings
are determined, they may be set at the Factory, or in the Integrators Shop. Similar installations
use the same settings, so cloning additional ICA-202D's is simple.
Since all critical settings are predetermined, field setup is very easy
The ICA-202D has an External Stepped Control, which allows the Operator to eavesdrop on
conversations not intended for communication, and easily return to "Normal Communications"
settings. An audio limiter assures that even at the most sensitive settings, the Operator speaker
will never be overloaded.
Configuration Templates support common applications. If there is not a template for your
application, give us a call; we will be pleased to assist you to configure the ICA-202D into your
design.
The audio quality of the ICA-202D is superb. Noise and distortion are very low. Selectable
equalization optimizes voice communications. The Automatic Level Control assures optimum
performance, the audio level remains constant over a wide dynamic input range. The user may
wander throughout the room and still be heard at a nearly constant level.
The ICA-202D features true 25-Volt audio outputs, with excellent features for two-way
communications. 20 Watts of reserve output power allows for All-Call and Paging without the
use of auxiliary amplifiers, greatly simplifying systems design and reducing overall cost.
The ICA-202D features an integrated Call Tone and selectable Privacy Tone. These signals are
adjustable, independent of the audio communications settings.
Line level transformer isolated outputs are provided for Monitoring, or Paging. The Monitoring
Output has each side (Jumper Selectable) of the conversation mixed to a single output ideal for
recording. The Paging Output is only present when the Page Switch is active, eliminating the
need for an external relay.
Modular Construction makes the ICA-202D ideal for integrated designs. The unit is small;
mounting is flexible and easy. Power is from a Universal Plug-in DC power adapter or screw
terminals for connection of any regulated 24VDC-2A Power Supply. All I/O is through Euro-Style
connectorized barrier strips. Unit is intended to use with class 2 power source.
