inputs, two emergency inputs (high priority) and mute function. MIC 1, EMC 1, EMC 2 are priority inputs, automatically muting all other signal inputs. MIC 1 has the highest
priority, able to suppress all other inputs. EMC 1 overrides all other inputs except MIC 1. Output from the YQ-15E emergency panel to EMC1 provides for alarm siren or emergency announcement to be broadcast over the public address system.
