Does the automatic fire alarm system include fire linkage?

Including, the automatic fire alarm system is composed of a trigger device, a fire alarm device, a linkage output device and other auxiliary function devices, it has the ability to produce smoke, heat, flame and other physical quantities produced by combustion in the early stage of the fire, through the fire detector into an electrical signal, transmitted to the fire alarm controller, and at the same time in the form of sound or light to notify the fire layer and the upper and lower adjacent layers to evacuate, the controller records the location of the fire, the time, etc., so that people can find the fire in time, and take effective measures in time, Extinguishing the initial fire and minimizing the loss of life and property caused by the fire is a powerful tool for people to fight against fire.

Relevant statistics show that where the automatic fire alarm system is installed, the fire can generally be called as soon as possible and will not cause a major fire. In many important office buildings, warehouses, substations, and control centers in our transportation port and shipping system, all kinds of ships of more than 500 gross tons have installed automatic fire alarm systems in accordance with the national standards "Code for Fire Protection Design of High-rise Civil Buildings", "Code for Fire Protection Design of Buildings" and relevant provisions of the "Solas Convention of the International Maritime Organization", which has played an important role in fire safety and security.

Not included. According to the actual situation, there is smoke exhaust, and the automatic fire alarm system should be linked with mechanical smoke exhaust; If there is a sprinkler, the automatic fire alarm system should be linked with the sprinkler. The linkage module can be increased according to the situation.

The automatic fire alarm and linkage control system must include linkage, otherwise it is meaningless to only call the police! However, in terms of construction responsibility, you can only be responsible for the control and feedback of the module, and the controlled equipment can not be considered, as long as the start-up can be started, the feedback can be feedback, and the system itself can work normally.

It is separated, in addition to the automatic fire alarm system, there are fire water system, automatic sprinkler system, gas fire extinguishing system, smoke exhaust air supply system, broadcast communication system, etc., which depends on the design requirements.

I think what you are asking should be whether the "automatic fire alarm control system" includes fire linkage, which is obviously included.

The automatic fire alarm controller is programmed according to the logic according to the fire alarm detector and the manual alarm button, and then the fire-fighting equipment is linked, for example: for example, two smoke alarms on the first floor of a high-rise building, according to the design requirements, the linkage elevator forced landing, wide cutting, lighting switching, the second floor of the floor, all basement sound and light alarms, positive pressure air supply open, positive pressure blower start, etc.

Inclusive. The automatic fire alarm system is divided into three basic forms: regional alarm system, centralized alarm system and control center alarm system.

The control center alarm system is a fire automatic alarm system with complex functions composed of fire linkage control equipment, centralized fire alarm controller, regional fire alarm controller, fire detector, manual fire alarm button, etc. Among them, the fire linkage control equipment mainly includes fire alarm devices, fire alarms, fire emergency lighting, fire emergency broadcasting, smoke prevention, ventilation and air conditioning, fire elevators and other linkage devices, as well as control devices of fixed fire extinguishing systems.

From the classification of automatic fire alarm system, it can be seen that the automatic fire alarm system includes a fire linkage device.

The linkage control design of wet system and dry system shall comply with the following provisions:

1. The linkage control mode should be controlled by the wet alarm valve.

The action signal of the pressure switch is used as the trigger signal to directly control the start of the sprinkler fire pump, and the linkage control should not be affected by the fire linkage controller being in an automatic or manual state.

2. In the manual control mode, the start and stop buttons of the sprinkler fire pump control box (cabinet) should be directly connected to the fire control with a special line.

The manual control panel of the indoor fire linkage controller directly controls the start and stop of the sprinkler fire pump.

3. The action signals of the start and stop of the water flow indicator, signal valve, pressure switch, and sprinkler fire pump should be fed back to the fire linkage controller.

The pressure switch of the alarm valve can directly start the sprinkler pump, and the fire host can start the sprinkler pump remotely.

The fire linkage control system is a set of systems that start various fire fighting equipment to alarm and extinguish the fire when the fire is confirmed. So what does it consist of?

The composition form of linkage can generally be divided into two forms: centralized control, decentralized control and centralized control, and its control mode includes linkage control, non-linkage control and linkage and non-linkage combination.

1. The fire linkage control system includes fire linkage controller, fire control room display device, transmission equipment, fire electrical control device, fire equipment emergency power supply, fire electric device, fire linkage module, fire hydrant button, fire emergency broadcast equipment, fire protection equipment and other equipment and components.

2. With the continuous development of various types of buildings, the scale of buildings is getting larger and higher, the level is getting higher and higher, and the standards of buildings are getting higher and higher. All kinds of new buildings have the characteristics of dense personnel, advanced equipment, multiple functions and luxurious decoration, so the automatic fire alarm and automatic fire extinguishing system has become an indispensable and important part of high-rise buildings.

The above is an introduction to what the fire linkage control system includes

The fire alarm controller is mainly for the input function of detectors, buttons, and modules, and it is only an alarm function.

The linkage controller refers to the output function of the module that needs to be controlled and the linkage control of the sound and light alarm that requires 24V linkage power line. It's not a computer but an alarm linkage controller.

Differences: 1. The fire alarm controller is the center of the system, which is responsible for the detection and alarm in the system and the management of the entire fire alarm system.

2. The fire linkage controller is a subsystem in the fire alarm system, which is only responsible for managing the internal stool lead control equipment and communicating with the fire alarm controller.

3. A system can have no linkage controller (for systems without linkage control requirements), but it cannot do without fire alarm controller.

Fire linkage - system scheme.

1 Structure of the fire alarm system.

In order to ensure that the safety of personnel and equipment in the building is in a strict management system, give full play to the maximum monitoring efficiency, and ensure that safety and fire prevention are foolproof, it is recommended that more advanced, high reliability and low false alarm rate products should be selected when selecting equipment. The system selected should have the following key features:

The intelligent detector should adopt the differential alarm judgment method, solidify the environmental parameters once an hour, the alarm curve generated in the detector is not affected by environmental factors, and the system false alarm rate is close to "zero".

If there is a communication failure between the detector and the controller, all the smart probes in the loop will switch to independent operation mode, and continue to collect and analyze the surrounding environmental information, with gross errors to ensure that the fire detection and alarm function is correct, to ensure that there is no false negative.

The controller can automatically address each detector and remember the installation position of each detector relative to other devices in the loop, and generate a wiring diagram of the device to ensure that the probe is not installed by mistake. The controller adopts broadcast addressing, the transmission distance is long, and the signal transmission is accurate and reliable.

The space unit and monitoring equipment on each floor adopt an intelligent trunk circuit, which is simple, clear and reasonable, and easy to maintain.

The controller adopts a distributed arrangement, which reduces the length of communication lines, saves investment, and improves the reliability of system work.

The modular structure of the system, flexible configuration, each intelligent loop address has ample room for expansion, high sensitivity, strong adaptability, and good adaptability.

The system has local manual, remote control manual, automatic measurement and control and other linkage control methods, which are diverse and effective to ensure the accurate operation and reliable operation of fire-fighting equipment.

The system has a high degree of integration, stable work, and adopts a graphical workstation, with friendly interface, intuitive management and simple operation.
