Question 1: What is the function of the fire alarm controller? Fire alarm controllers generally judge whether a fire has occurred by detecting and analyzing some characteristics of the fire and according to preset built-in parameters. Generally, it can be divided into smoke detector, temperature detector and light detector.

Smoke detector: As the name implies, it collects the smoke concentration in the environment at a certain frequency and analyzes its composition. Generally speaking, after a fire, the concentration of CO2 and toxic gases in the air will increase significantly. When the concentration reaches a certain value, the detector thinks that there is a fire and will call the police. Of course, sometimes the concentration increase caused by smoking will be treated as a fire, so smoking is generally prohibited in places with smoke detectors.

Temperature detector: detect the ambient temperature in real time. Once the energy with high temperature is found, it will be analyzed. If the temperature change trend is similar to the fire itself, it will be treated as a fire.

Photosensitive detector: light is the result of heat source radiation, so light is also inductive radiation, and the human body constantly radiates waves. However, due to the low temperature of the corpse, the wavelength of radiation wave is generally large, and the light emitted by the heat source of fire is strong and can be detected. According to the analysis of some scientists, a unique sound wave will be emitted when a fire breaks out, and making sound detectors based on this wave can effectively overcome the common mistakes of other detectors. These are all under study, if you care about this knowledge.

Question 2: What are the functions of fire alarm controller and fire linkage controller respectively? The fire alarm controller mainly aims at the input functions of detectors, buttons and modules, but it is only limited to the alarm function. Linkage controller refers to the linkage control of the output functions of several modules that need to be controlled and the acousto-optic alarm that needs 24v linkage power line. At present, most of them are combined with alarm linkage machine, and alarm and linkage are not set separately; That's not a computer, it's the display of the alarm linkage controller.

Question 3: What is the difference between fire linkage controller and fire alarm controller? Thank you for saying that the linkage module should be a linkage control module, which is one of the relay modules of the fire alarm controller, as well as an isolation module and a monitoring module. In the area where the fire alarm system is installed, when the protected object has a fire, the fire parameters such as sound, light, temperature and smoke in this area will change, and the detector will convert them into corresponding fire signals and send them to the monitoring substation, or the personnel will press the manual alarm button to send signals to the monitoring substation after discovering the fire. The function of linkage control module is to realize the fire alarm or fire extinguishing function of related equipment in the protected area when the monitoring substation receives these alarm signals. Generally, in the automatic state, the manual alarm signal takes precedence, and the control module will directly start the acousto-optic alarm, broadcast or fire extinguishing system in the alarm area; In case of single-loop alarm, generally only the existing acousto-optic alarm or broadcast alarm system is started; in case of double-loop or multi-loop alarm, the alarm and fire extinguishing system are started at the same time. In fact, for users, it is not necessary to understand the principle of this relay module, it is only an indispensable part of the fire alarm and fire extinguishing system, and they must be maintained and repaired by professionally trained qualified personnel. Personal suggestions only need to know the function, realization way, usage method, daily inspection method and professional maintenance of this system, so leave it to professionals!

Question 4: What is the operation level of the fire alarm controller? GB47 17-2005 fire alarm controller

You don't need a password to enter the first level, and you should use keys and operation numbers to enter the second and third level operation function States. Keys or operation numbers used to enter class III operation function state can be used to enter class II operation function state, but keys or operation numbers used to enter class II operation function state cannot be used to enter class III operation function state. The four-level operation function cannot be performed only by the controller itself.

* * * There are four grades.

I: Anyone.

Ⅱ: Operator

III: administrator (debugger)

Four: Manufacturer

Question 5: What brands of fire alarm controllers are there? China has more than 100 brands.

Widely used are: Bay, Beida Jade Bird, Lida Huaxin, Songjiang, Taihe 'an, Nite, Yi 'ai, Yingkou New Shan Ying, Siemens, Nuodifei and so on. Reference page: dnfire/brand.php

Question 6: The function of fire alarm controller in fire protection system. The fire alarm controller is the brain of the whole system and the centralized management and monitoring center.

The field alarm device communicates with the controller. For example, the alarm of the field detector will be displayed on the controller, and the controller will link the field equipment. The running state of the whole system can be known in the fire control room.

Question 7: Automatic fire alarm system, the main component of fire alarm controller.

The automatic fire alarm and fire fighting linkage control system is one of the systems that must be set up in intelligent buildings. Through the fire detectors arranged at the scene, signals such as smoke, fire and hot gas can be automatically monitored when a fire occurs. In case of fire, sound and light alarm signals are sent out, and relevant fire-fighting equipment is linked at the same time to realize detection alarm and control fire extinguishing.

Modern buildings have large scale, high standards, dense personnel and various equipment, and the requirements for fire prevention are extremely strict. Therefore, in addition to the layout of buildings, the selection of building and decoration materials, the selection and configuration of electromechanical equipment and many other restrictions, modern fire-fighting facilities are also needed. With the development of China's economic construction, various high-rise buildings, large and medium-sized commercial buildings and factories are constantly emerging, which puts forward higher and stricter requirements for the automatic fire alarm system. In order to find and report fires as early as possible, prevent and reduce fire hazards, protect personal and property safety, and ensure socialist modernization, automatic fire alarm system has become an indispensable facility in modern industrial and civil buildings, hotels, libraries, scientific research and commercial departments. Whether the design, installation and use of electrical engineering are correct not only directly affects the fire safety of buildings, but also directly affects whether various fire-fighting facilities can really play their roles. Therefore, the design of automatic alarm and fire fighting linkage and the selection of equipment are particularly important.

Equipment composition:

The host module must form a system with the detection and alarm module, broadcast telephone module and linkage control module.

Question 8: What is the use of the tab key on the fire alarm controller, similar to the paging switching function of the submenu? So as to refer to the contents of the submenu.

Question 9: How many power sources does the fire alarm controller have? That's right. The two power supplies are powered by two alternating currents. Using bidirectional power converter, when a power supply fails, it can supply power to a power supply immediately.

Direct current is the battery pack in the main engine, and the electric field is 24VD. After the main power supply is cut off, the direct current of the battery can provide power for the fire fighting host for a period of time.

Question 10: What are the functions of fire alarm controller and fire linkage controller? The fire alarm controller mainly aims at the input functions of detectors, buttons and modules, but it is only limited to the alarm function. Linkage controller refers to the linkage control of the output functions of several modules that need to be controlled and the acousto-optic alarm that needs 24v linkage power line. At present, most of them are combined with alarm linkage machines, and there is no separate alarm and linkage; That's not a computer, it's the display of the alarm linkage controller.
