Background music system schematic

With the advancement and development of society, people's work and life rhythm is getting increasingly faster. It is therefore necessary to have a relaxed, harmonious and safe working and living environment. The public broadcasting system in the building would work well for the requirements. On the one hand, under normal circumstances, the system could work as a medium for background music, which helps beautify the public environment; On the other hand, under emergency circumstances, it could rapidly make radio calls, guide personnel evacuation, cooperate with fire alarm system, anti-theft alarm system, and the security surveillance system, which effectively forms a complete, three-dimensional disaster-proof and security facility with audio-visual functions.

The system can be equipped with multiple sets of programs, which are managed by the information command center. The whole system could be divided into two parts: background music and emergency broadcast (ie fire broadcast), which are mainly distributed in the square, parking lot, public access and office areas.
