6.3.5 Connecting control inputs
The audio expander has 8 control inputs. The control
inputs can receive signals from third party equipment
that must trigger actions in the Praesideo system. The
control inputs can be configured to act on contact make
or on contact break (see section 43.5). It is also possible
to supervise the cables for short-circuits and open
connections (see figure 6.5 and figure 6.6). Whether a
control input is actually supervised or not is defined in
the configuration.
