The GK702 fire alarm controller adopts 12C bus technology and multi-CPU technology inside to be used in a large-scale fire automatic alarm system. With a large screen and color LCD display in Chinese, it is convenient and intuitive to operate, and standard capacity of the controller has 10 pieces of GK7024 intelligent circuit cards and 5100 coding points. The controller can be expanded with 2 expansion cabinets, and the capacity can reach 64 circuits. There are 16320 code points. The networking of 255 controllers can be realized through a CAN bus, and the networking of 1024 controllers can be realized through the router GM741. The controller provides the communication port 485 and PC for two-way communications, and can be connected to the CRT graphic display system. It can provide the communication protocol 485 to connect with external systems such as city networking. The independent port 485 can be used to communicate with the fire display panel and other equipment. The controller has the function of audible and visual alarming and broadcasting alternately. The electric isolation technology is adopted to effectively prevent other voltages from entering the site and causing damage to the equipment, and the reliability of the controller is improved.
