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 2-7). 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 panel’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 2-7).
BINAURAL HEADSET WIRING
Although the panel has a second earphone output, it functions and is
wired differently than some other ICS panels. The output is not
available on the “Miscellaneous” connector, but on the panel’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
panel.
The default configuration of the panel has both earphone outputs being
fed with intercom and program audio. Figure 2-8 shows the wiring of a
six pin XLR connector for a binaural headset.
