ICS-2003 INTERCOM STATION
2-8
Both normally open and normally closed contacts are provided. They are rated at
1 Amp at 24 VDC. This relay is not designed for switching mains AC line
voltage. To switch an external device running on mains AC line voltage, use an
external relay (or other switching mechanism) activated by this relay (see Figure
7). The following table shows the pins available for the SA relay.
Auxiliary Audio Line Level Output
The Auxiliary Audio Line Level output is a balanced, line-level,
transformer-isolated feed of the input to the station’s internal speaker. For
example, this output could be used to feed an external amplifier connected to
loudspeakers.
Connect to pins 6 and 13 for a balanced output. Pin 14 is available as a shield or
ground source (see Figure 7).
BINAURAL HEADSET WIRING
Although the station has a second earphone output, it functions and is wired
differently than some other ICS stations. The output is not available on the
“Miscellaneous” connector, but on the station’s main board on a separate header
connector. This output would be available if a six-pin headset connector is
installed on the front or rear of the station.
The default configuration of the station has both earphone outputs being fed
with intercom and program audio. To separate the program input to the second
ear only, use the configuration program.
Figure 8 shows the wiring of a six pin XLR connector for a binaural headset.
