The function of fire alarm controller in fire fighting system
At present, different brands of fire alarm controller circuit boards can not be used instead of each other. Some brands fire alarm controller circuit boards are also divided into single circuit board and double circuit board. The dual circuit board is a combination of two single circuit boards, a double loop board equal to two single circuit boards. For example, I have a system with 7 loops, so I can use 3 dual circuit boards and a single loop board.
In fact, the provision of loop wiring platform. Generally more fire alarm controllers need circuit boards, such as * * Brand fire alarm controllers, each of which supports 127 points. If a fire auto alarm system needs 1000 points in total, then we can calculate the 800/127=6.3. Note that the decimals here should be carried, not four to five. By calculation, we know that we need to buy a fire alarm controller to buy 7 loop points. Each circuit needs a circuit board hardware.
Fire alarm controller circuit board is not necessary for each fire alarm controller, such as some small number of controllers do not need circuit boards. It is hoped that the reader will assist in the above information when purchasing the fire alarm controller.
The fire alarm controller is the brain of the whole system, and is the centralized management and monitoring center.Field alarm devices are communicated with the controller, such as on-site detectors, alarm will be displayed on the controller, controller and linkage field equipment. In the fire control room, you can know the running state of the whole system.
