The ICA-202D is the most versatile Audio Intercom
available; yet it is also the easiest to integrate into
your design. With 20 watts of clean audio power at 25-
Volts it can do both the Intercom and the Paging
functions in most facilities. The audio quality of the
ICA-202D is superb. Noise and distortion are very low.
Selectable equalization optimizes voice
communications.
There are separate controls for Audio Level, and
Reach. Once set, Automatic Level Control (ALC)
assures the speaker level remains constant over a
wide dynamic input range. The Remote user may
wander throughout the room and still be heard at a
nearly constant level without any operator
adjustments.
A Privacy Tone, to alert the remote party that
someone is listening, is a control option. If selected
the privacy tone will sound every 20 seconds unless
the PTT is pressed.
The logic interface is PLC compatible. Control options
include Remote Operator Listen Level control from
push buttons or Touch Screen, Privacy Tone, Page,
PTT, Mute, Activate, Shut Off, and Call Tone, which is
automatically routed to the operator speaker. A Line
level output for recording is included. A separate Page
line level output provides audio to paging amplifiers if
required. A Page Pre-Announce Tone (jumper option)
is available.
All configuration settings are factory presets; only the
speaker levels are set in the field. The microphone
sensitivity (Reach) is set with 16 position (3dB/Step)
switches; the Speaker Levels are adjusted with Back
Panel Controls.
