3.10
operational data storage unit
unit that is used for recording the operating condition information of all fire alarm trigger devices and automatic fire protection equipment connected with the control unit for reference in fire investigation
3.11
fire electrical control equipment
unit that controls various automatic fire protection facilities such as fire water supply equipment, automatic fire extinguishing equipment, indoor fire hydrant equipment, smoke management equipment, fire doors and windows and fire-resisting shutters, and has the functions of controlling the controlled equipment to execute predetermined actions, receiving feedback signals from it and monitoring its condition, communicating information with automatic control unit for fire protection or control unit with automatic control function, and sending acoustic and optical prompt information to users
3.12
automatic control communication module
communication module with a function of communication protocol conversion that can realize information interaction between an automatic control unit for fire protection or a control unit with automatic control function and various fire electrical control equipment
3.13
fire system alarm bus; FAbus
communication line in the automatic fire alarm system that is used for transmitting the information between a fire alarm trigger device and a fire alarm control equipment
3.14
fire system control bus; FCbus
communication line in the automatic fire alarm system that is used for transmitting the information between an automatic control unit for fire protection or a control unit with automatic control function and an output module, input module and input/output module
3.15
fire system equipment control bus; FECbus
communication line in the automatic fire alarm system that is used for transmitting the information between an automatic control unit for fire protection or a control unit with automatic control function and the fire electrical control equipment such as gas extinguishing subsystem, fire pump monitoring subsystem, smoke management monitoring subsystem, fire emergency broadcasting and telephone subsystem, fire-resisting shutter monitoring subsystem, fire door monitoring subsystem, fire emergency lighting and evacuation indication system through the automatic control communication module
4 Classification and designation
The control units are classified as follows based on the application method:
a) independent control units (without the function of transmitting information to other control units);
b) regional control units (with the function of transmitting information to other control units);
c) centralized control units (with the function of receiving information transmitted by other control units and displaying the information in a centralized way);
d) centralized regional compatible control units (with the functions of regional control units and centralized control units).
