Each building should be clearly separated, and then clearly read the previous drawing design instructions and legends, among which there are various symbols and markings. Then look at the system diagram. Finally, the fire plan of each floor can naturally be read.

2. The view of the fire drawing: the pink line is called the loop bus, the green is the power line, the blue is the telephone line, and the yellow is the broadcast line. In general, except for the fire broadcast speaker and the fire bus telephone branch, a loop bus should be introduced to each other fire device. If there is a control module, a power cord should also be introduced.
