Connect to pins 1 and 9 for a balanced SA audio output. Pin 2 is
available as a shield or ground source (see Figure 2-5).
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 2-5). 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 2-5).
MAINS AC POWER
The ICS-102/ICS-102T panels and ICS-62/ICS-62T panels can be
powered by any source supplying between 12 and 16 V RMS AC at
750 mA. The panels are shipped with a wall-mountable transformer
that provides 14 V RMS AC to the panel.
Two types of transformers are available: one operates on a mains AC
input power of 117 V (part number 730166) and the other operates on
a mains AC input power of 220 V (part number 820049). Make sure to
specify the proper transformer when ordering the panel.
To connect the transformer, route the cord from the transformer’s
secondary to the panel’s “AC Power Input” connector on the rear
panel. This is a 2.1 mm coax connector. When routing the cord make
sure to use the stress relief on the rear panel.
The power input to the panel is internally protected with a 0.9 a “poly
fuse,” a self-healing fuse that will recover when the fault is removed.
