For public areas in a property, digital Public Address systems can be used to provide site-wide background music and audio paging from multiple sources at different locations and in different zones. These systems can be integrated with fire alarm systems and intruder alarm, which will be of utmost convenience for the property owners. While background music provides a relaxed environment in the property, the audio could be used for information dispersion and hazard notification.
