Automatic Fire Alarm System

Fire alarm linkage control system the fire alarm linkage control system is part of the automatic fire alarm system that receives fire alarm signals from the fire alarm control panel and performs various fire safety functions according to preset logic. It is composed of devices and components such as the fire alarm linkage controller, fire control room graphic display unit, fire electrical control units (including controllers for fire shutters, gas extinguishing systems, etc.), fire motorized devices, fire alarm linkage modules, fire hydrant call points, fire emergency broadcast system, and fire telephone.

• Fire Alarm Linkage Controller: The fire alarm linkage controller is the core component of the fire alarm linkage control system. It receives fire alarm signals from the fire alarm control panel or other fire-triggering devices and, based on preset control logic, carries out linkage control of the automatic fire protection systems (facilities) installed within the building. The fire alarm linkage controller can directly send control signals to drive devices that operate the controlled equipment on site. For complex control logic that is difficult to implement directly on the fire alarm linkage controller, controlled equipment can be indirectly managed through the fire electrical control unit (such as fire shutter controllers, gas extinguishing controllers, etc.), while also receiving feedback signals from the automatic fire protection system (facilities).
• Fire Control Room Graphic Display Unit: The fire control room graphic display unit receives and displays dynamic information and fire management data about various fire systems and equipment within the protected area. these include fire detection alarms and linkage control systems, fire hydrants, automatic extinguishing systems, smoke prevention and exhaust systems, fire doors and shutters, elevators, fire power supplies, emergency lighting and evacuation indication systems, fire communication systems, and more. It also supports information transmission and recording functions.
• Fire Electrical Control Unit: The fire electrical control unit controls various fire electrical devices, typically operating manually or automatically, to activate fire pumps, smoke prevention and exhaust fans, motorized fire doors and windows, fire shutters, motorized valves, and other electric fire facilities. It also provides feedback on the operating status of these devices to the fire alarm linkage controller for display.
• Fire Motorized Device: A fire motorized device refers to the electrical driving or releasing mechanism for electrically operated fire doors and windows, fire dampers, smoke dampers, smoke exhaust dampers, gas actuators, and other electric fire protection equipment.
• Fire Alarm Linkage Module: A fire alarm linkage module is a device used for signal transmission between the fire alarm linkage controller and its connected controlled equipment or components, including input modules, output modules, and input/output modules.
• Fire Hydrant Call Point: A fire hydrant call point is an alarm button designed to indicate the activation and location of a fire hydrant.
• Fire Emergency Broadcast System: The fire emergency broadcast system consists of control and indication devices, audio power amplifiers, microphones, speakers, broadcast distribution units, power supplies, and other components. It is used for emergency broadcasting by controlling power amplifiers and speakers during fires or other emergencies.
• Fire Telephone: The fire telephone is a telephone system used for communication between the fire control room and different locations within the building. It is composed of the fire telephone switchboard, fire telephone extensions, and fire telephone sockets.

Fire Early Warning System: The fire early warning system mainly includes the combustible gas detection and alarm system and the electrical fire monitoring system.

• Trigger Devices: Trigger devices within the Automatic Fire Alarm System are those that automatically or manually generate a fire alarm signal, primarily comprising Fire Detectors and Manual Call Points.
• Fire Alarm Device: A fire alarm device in the Automatic Fire Alarm System is a control and indication device used to receive, display, and transmit fire alarm signals, issue control signals, and provide other auxiliary functions. The Fire Alarm Control Panel is the most basic type.
• Fire Alarm Device: A fire alarm device in the Automatic Fire Alarm System emits fire alarm signals that are distinguishable from ambient sound and light. It issues fire alarm signals through sound, light, or other means to the alarm zone, alerting people to promptly undertake safe evacuation and firefighting measures.
• Power Supply: The Automatic Fire Alarm System belongs to firefighting electrical equipment; its main power supply shall use a firefighting power supply, while the backup power supply may use a storage battery. Besides supplying power to the Fire Alarm Control Panel, the system power supply also powers related fire control equipment.
