Abstract: The guard alarm broadcasting system is introduced. The system’s structure, principle and implementation are described. The system uses RS-485 bus technology to create a master-slave alarm broadcasting networks, four-color alarm linkage. The system has the advantages of wiring simple, strong anti-interference ability to meet the actual needs of guard duty.

Key words: RS-485 bus, Four-color alarm, Guard duty, Alarm broadcast
