External switch ( eg. fr emergency paging mic with dry contact ) can be connected here, which shall trigger
the built in relay when pressed. This shall then provide a dry contact in which would enable the installer to
apply several functions such as providing 24V DC output for volume controller overriding purpose, trigger
external device or link to BAS system, etc.
