Design Project for Bell Ring, Background Broadcast and Gym Music Broadcast in School

Project Overview
The total area of the campus is 12000M2 , including the following parts:
1, 2, 3: Class rooms of junior grade one, junior grade two and junior grade three, six classes in each grade;
4, 5, 6: Class room of senior grade one, senior grade two and senior grade three, six classes in each grade;
7. Junior high school teaching building aisles, three stories in total;
8. Senior high school teaching building aisles, three stories in total;
9. The area of the library is 800M2 , two stories in total;
10. Sports ground and flag raising ground.

User Requirements
The whole set of device adopts unmanned monitoring system and friendly operating interface make the operation simplifying;Timing broadcast of rings, gym music and background music must be available;
Zone broadcast must be available to deliver different broadcast to different zones or different grades;
Direct paging from control-room or principle office to designated zones without affecting other zones broadcast must be available.

System Configuring and Design Project
1. The system should be complete with control functions, be easy to operate and can broadcast a wide range of programs;
2. The system should have a good compatibility, extensibility and auto-detecting function;
3. The system should be able to connect the fire-fighting system and can serve for fire emergency broadcasting system when the alarm rings.

System Configuring and Design Project
