The difference between fire and fire alarm system and bus system
The bus is the automatic fire alarm system and fire linkage system signal transmission line be made one in the loop, i.e. both detector, manual alarm button, and a control module circuit ganged fire control facilities and receive the feedback signal of action. That is, the device is connected in parallel to one of the buses. Using bus system, wiring is relatively simple. Under normal circumstances, if the number of fire linkage facilities is relatively large and centralized, the bus system is more economical and reasonable.
The fire alarm is a profiteering industry, there is no unified form of fire alarm system, and the provisions of the explanation is: fire alarm systems, fire automatic alarm system.The utility model is composed of a fire alarm host, a fire characteristic or an early fire characteristic sensor, an artificial fire alarm device and an output control device.
Multi line control is controlled by the main control room for manual control. It is usually not controlled by the alarm system and controlled by human. Use relay, contactor to complete. Multi line control of fire linkage is one to one, point to point control loop.
