The CFSound III is expandable using IO modules and amplifiers. IO
modules can be added to provide contact inputs and outputs to the CFSound
8 Contact Inputs(Optically isolated - connect to Ground to
terminal blocks are used for connections
Output modules provide individually controlled relay closures, that activate
during playout of the corresponding audio file. This can be used to
trigger, activate, route audio, etc.. when audio files are played, allowing the
CFSound II to provide a complete stand alone control or automation system.
Input modules provide triggering/control of how and when the audio files
play. Individual wav files may be named so that they play when the
corresponding inputs is opened(active to non-active), closure(non-active to
active), open(while not active), closed(while active). The input pins are
12VDC, and are brought to ground(negative) to activate.
Combination input and output modules are available to
provide triggering(input) of an audio file, as well as activating
an output for the duration of the playout. This can be used to
create interactive audio messages/responses.
can be triggered on individual input being opened(active to non-active),
closure(non-active to active), open(while not active), closed(while
