The Western China Science and Technology Innovation Harbour Wisdom Uni-Town, with a total area of 23 square kilometers and a construction land area of 10.5 square kilometers. As the project covers a large area, the single building has a large volume, a large number, a long distance, multiple functions and a wide distribution, the control center alarm system is appropriate for the fire automatic alarm system. It has fewer application projects with complex system and many fire control rooms, there are difficulties in the aspect of system construction, communication networking and equipment linkage.
