◆ Internally adopting CAN bus technology and modular design, it has the characteristics of strong functionality, high reliability, and flexible configuration.

◆ The maximum capacity of the controller is 32 GK7024 circuit boards, each with 2 circuit buses. Each circuit bus can connect 255 encoding points, with a maximum capacity of 16320 encoding points.

◆ The expansion circuit box does not occupy the panel position, but occupies the rear position of the cabinet. It is designed with 5U and can share the panel with the bus operation panel.

◆ The bus operation panel GK743 controls 64 points each, with a maximum of 20 points and 1280 points.

◆ The GK741 linkage control panel controls 16 points each, with a maximum of 13 points and 208 points.

◆ Programming can be done using a keyboard or offline through a USB interface on a computer, or programming data can be downloaded or software can be upgraded using a USB drive.

◆ By selecting the RS485 communication board (GK7442), the CRT graphics display system can be connected.

◆ Adopting an 800 × 480 dot matrix color large screen LCD display, it is clear, intuitive, and easy to operate.

◆ The black box function can store 4096 fire alarm records and 20480 other event records, accurately and fully recording system status events.

◆ By selecting the CAN communication board (GK7441), 255 controllers can be networked, with a maximum distance of 3km for controller networking (adding 1 CAN relay router for every additional 3km).

◆  It can automatically compensate for sensitivity drift caused by external non fire factors such as temperature, humidity, and dust accumulation, and intelligently process fast changing signals such as electrical interference.

◆ Three level programming password protection, compatible with password levels downwards, suitable for operations by different categories of personnel.

◆ Manual start function, convenient for checking the device's startup configuration.

◆ The micro thermal printer realizes real-time event printing function.

◆ Rich matrix control functions make programming more efficient and flexible.

◆ It has real-time operation prompts and can display geographic location information for easy operation and management.

◆ The automatic login function of circuit components enables intelligent and fast online operation of circuit components.

◆ Powerful network query function, the controller can query the configuration information of any controller in the network.

◆ Powerful network control function, allowing controllers to cross machine control or operate certain settings.

◆ Special function definitions for circuit modules (fire pumps, fire dampers, air conditioning units, etc.), with a complete range of types.

◆ It has linked programming macro instructions, such as "Ren Lou", "Ren Qu", and "Ren Lou", which facilitate the automatic control of the controller.

◆ Nine grid input method, convenient for on-site text editing.
