【 Weak current college 】 building weak electricity system---the first section of the automatic fire alarm system

Fire protection system is a modern building the necessary safety equipment. 　　This section describes the automatic fire alarm and the basic principles of automatic fire-extinguishing, fire alarm system of classification and basic composition, functions, common equipment, fire control, style and functionality requirements, and details the automatic fire alarm and fire control system installed and opened the requirements and steps for debugging.　　Ask the readers from property facilities management perspective, learn more about building fire system composition and working principle, understand the common fire equipment and its maintenance of way to ensure the efficient use of buildings, especially master fire system works as well as related equipment facilities, functions and features. First, the fire system overview 1. commonly used fire protection system as a result of different forms, different structures, different features of the building, fire protection systems have different standards and requirements and, therefore, should be used in accordance with the building of the nature, the risk of fire, evacuation and rescue the degree of difficulty, with a corresponding function in fire-fighting system.　　At present, in the building of the more commonly-used fire-fighting system with automatic monitoring artificial fire extinguishing system and automatic monitoring of automatic fire extinguishing system. Automatic monitoring artificial fire-extinguishing system is a semi-automatic system, applicable to general industrial plants, general store and small and medium-sized hotels and other buildings.　　When the system probes to detect fires, the regional fire alarm will emit a beep signal while detector output signal into the fire, the fire Centre display can show the fire floor or region code, the fire officer under alerts, take measures to the fire. Automatic monitoring of automatic fire extinguishing system is a fully automatic fire fighting system, suitable for important office building, advanced hotel, substations, telecommunications, computer room, TV room, a library, archives and flammable materials warehouse, etc. Current smart buildings generally adopt this system. This system sets up a comprehensive set of automatic fire alarm and fire control system.　　When you want to fire, the detector immediately detected fires into electrical signals to the fire Centre of fire alarm control, fire alarm controller output alarm signal, the output control signal, control linkage related fire fighting equipment, fire fighting, the implementation of the regional fire automation.　　In the automatic fire fighting system, or you can manually control alarm and fire extinguishing.　　2. automatic fire alarm and automatic fire extinguishing the basic principle of intelligent building automation, fire-fighting system with automatic fire alarm and fire two subsystems, its composition as shown in the figure on the right. The figure shows that the fire alarm control unit is the heart of the entire system, it is an analysis, judgement, records and displays the fire of intelligent devices. Fire alarm controller continued to probe (probes) issued surveys signal monitoring charged region of smoke concentration, temperature, etc., you will represent the smoke detector concentration, temperature and electrical signal feedback to alert controllers that alarm controller will these feedback signal and memory storage of the regional fine tuning of value analysis to determine if there is fire. When confirmed, when the fire alarm controller first sends sound and light alarm, prompting the duty officer at the controller also displays detect smoke concentration, temperature and equivalence and fire district or Club level room number address encoding, and these values and the time the fire broke out.　　At the same time to the scene of the fire and the adjacent floor give sound and light alarm signal. For convenience, the General will automatically fire suppression system and its chain of smoke control equipment, fire doors, fire and emergency lighting, fire prevention and mitigation system collectively known as automatic fire extinguishing system.　　Automatic fire alarm controller has multiple sets of linkage control automatic fire extinguishing device output contact, when its confirmed fire, on the one hand control alarm alert, on the other hand, the command output control signal fire actuator (relay, solenoid valve, etc.), open the spray valve, started the fire pump on the exhaust fan power supply, etc, for fire suppression.　　Similarly, in order to prevent automatic fire extinguishing system failure, forfeiting, equipped with fire suppression, disaster mitigation devices such as fire-fighting water valve, the throttle and, in addition to setting the manual control switch, installation manual mechanical switches. Statistics show that in high-rise building fire due to flue gas suffocation and poisoning deaths is far greater than the number of people burned to death, so the importance of early warning, also special needs automatic alarm and automatic fire-fighting, in order to reduce the losses quickly. If there is no automatic fire extinguishing, amid the success rate is not to escape 15%, if you have automatic fire fighting system and reasonable assistance, more than 95% of casualties will not appear. 　　Our country through the issuance of the senior civil building design fire protection standard and the automatic fire alarm system design specifications ", on high-rise building of automatic fire extinguishing system implemented mandatory installation requirements and regular inspection control, and the building is equipped with automatic fire system, referred to the legal level. Second, the automatic fire alarm system is composed of automatic fire alarm system in General by the trigger, fire alarm system, fire alarm devices and power supplies, the four components.　　Complex system also includes fire control devices. 1. triggers for automatic fire alarm system, automatic or manually generate fire alarm signal device known as a trigger.　　Includes fire detectors and alarm buttons manually.　　Currently, fire detectors, many types of different functions, common detector based on its detection of physical quantities and work, you can press the right figure. In practice, it should be in accordance with the relevant provisions of the existing national standards and reasonable choice. Fire detectors are automatic fire alarm system of the largest, most extensive applications, most basic trigger. In recent years there is a known as analog-type detector fire detectors are increasingly being applied in practice. This detector output signal is represented by the responding fire parameter value analog signal or its equivalent of a digital signal. Unlike traditional a threshold detector (or switch signal detector), the difference is that there is no threshold of fire detector, it only acts as a sensor, itself does not determine the fire. Analog detector applications, will help to raise the fire detection and alarm system to report accurate and intelligent, the detection and alarm system technologyAn important symbol of progress. Another category triggers is manual fire alarm button.　　It is manually produced fire alarm signal to start the automatic fire alarm system of the device, it is the automatic fire alarm system is an indispensable part.　　2. fire alarm system in the automatic fire alarm system, to receive, display and transmission of fire alarm signal and can send control signals and other accessibility features of the control indicates that the device is called a fire alarm installations. Fire alarm controller is one of the most basic, it is also known as automatic fire alarm controller is the intelligent fire protection system part of the core.　　Fire alarm controller can pose a fire and fire detector automatically monitoring and alarm system, if the linkage control fire-fighting equipment, fire prevention and disaster mitigation devices together, constitute a complete range of automatic fire alarm and automatic fire extinguishing system. Fire alarm controller product designation is in accordance with the professional standards of People's Republic of China (ZBC81002-84), the current domestic manufacturers are using this naming method. Modern fire alarm controller, integrated into the advanced electronics technology, computer technology and automatic control technology, which increasingly complete, performance and more perfect, the structure has been completed by the analog-to-digital conversion. Its features include the following points. ① can quickly and accurately send alarm signal. When the fire alarm controller receives a signal from the detector of alarm, once confirmed, the immediate fire signal output. On the one hand, the controller issued its own alarm sound and light alarm, while also controlling the fire of sound, light and alarm device alerts. ② fire alarm controller issued fire signals at the same time, you can output control signals start of fire and disaster reduction equipment. Control signal available in high and low voltage signal outputs, you can also use the switch contact signal output. At present, generally through the various features of output modules to output control signals. ③ fire alarm controller for post while testing whether failure, fire detectors and breakage, short circuit and undervoltage, failure, and the issue of sound, light alert. ④ with fire alarm priority function. When the fire and trouble simultaneous or failure and fire (failures and fires are not on the same site) and fault alarm will give way to the fire alarm. ⑤ with storage memory. When the fire alarm or fault alarm, fire or failure of memory addresses and time, only when the artificial reset memory before they disappear. 　　⑥ provide work for fire detectors. In accordance with the purposes, the fire alarm control unit is divided into regional fire alarm controller, centralized fire alarm controller and universal fire alarm controller three basic types.　　In recent years, with the fire detection and alarm technology development and analog, bus systems and intelligent fire detection and alarm system gradually applied, in many occasions, fire alarm controller is no longer divided into regional, concentrated and universal three types, which are collectively referred to as fire alarm controller.　　In fire alarm equipment, others such as the Repeater, regional monitor and fire show up, not a complete alarm system, they can be considered a fire alarm controller evolution or supplementary, under specific conditions, and the fire alarm controller with a fire alarm installations. 3. fire alarm installations of automatic fire alarm system to make sound, light a fire alarm signal device called a fire alarm installations.　　Fire alarm is one of the most basic fire alarms that sound, light, sound, and other ways to alert issued fire alarm signal area to alert people to take fire evacuation, disaster relief measures. 4. fire control when it receives from the trigger of fire alarm signals, can automatically or manually initiated associated firefighting equipment and displays the status of the device, known as fire control. Includes fire alarm controller, automatic fire extinguishing system control unit, indoor hydrant system control device, the smoke exhaust system and air conditioning ventilation system control device, normally open fire doors, fire shutter control unit, Elevator back drop control equipment, and fire emergency broadcast, fire alarms, fire emergency lighting and evacuation signs of control equipment, etc. 10 class control device in part or in whole. Fire control equipment General settings in the fire control centre to implement centralized control.　　There is also a set of fire control equipment in the charged field of fire equipment is located, but the action signal must return fire control rooms, centralized and decentralized way of control. 5. power key power should fire power, standby power supply with battery.　　System power except for fire alarm controller power supply for system-related fire control, power supply. 3. automatic fire alarm system of classification and function outside the fire alarm controller products only, no area size and focus. Our bus system for fire alarm controller product is in the region, centralized, common coexistence period three forms.　　The following according to region, set and control center three basic alarm system forms. Typically, regional alarm system should be used for secondary protection object, set the alarm system suitable for primary and secondary protection object, the control centre of the alarm system should be used for special grade, level, protection of objects. In engineering design, on a specific protection objects of the alarm system, according to the specific situation of the protection object to determine the reasonable. 1. regional alarm system area alarm system is made up of regional fire alarm controller, fire detectors, manual fire alarm button and fire alarms, fire auto-alarm system, its composition the block diagram shown below. Zone alarm control system area alarm controller often is the first level control alarm device.　　In a large high-rise buildings, it is generally installed in the floor; in a small group of buildings, it is generally in the warning area delineated by a fixed location. In addition, in central alarm system and the control centre of the alarm system, fire alarm controller is essential equipment. Regional alarm system should be aware of the issues described below. ① individual use of an alarm system, alarm zone should be set up a regional fire alarm controller and, if necessary, you can use two computers. If you need to set up regional fire alarm controller for more than two, shall consider centralized alarm control system. ② When using a zone fire alarmController vigilance multiple floors, in order to fire detectors and alarm, managers can be timely and accurate alarm locations, take prompt measures to fight, each floor landings Department or fire the elevator room obvious place set the fire floor lights display device. ③ zone fire alarm controller should be set on an on-duty room or place. 　　If you do have difficulties should be installed in the floor corridors, workshops and other public places or regular duty personnel management patrols. 2. set the alarm system centralized alarm system is centralized fire alarm controller, regional fire alarm controller, fire detectors, manual fire alarm button and fire alarms and other components of the functions of the more complex the automatic fire alarm system, its function as shown in the figure below. Set alarm control system set alarm systems are generally the area alarm controller of host controller that is the entire building fire system total monitoring equipment, generally installed in large buildings in fire control centre, features more than area alarm controller.　　Set alarm controller can directly receive fire detectors and alarm signals. Central alarm systems are typically used to feature more buildings, such as high-rise hotels, restaurants, etc. At this point, the central fire alarm controller should be set to be on duty fire control room or watch indoor, regional fire alarm controller settings in each layer of the help desk Department. System device layout should note the following issues. ① centralized fire alarm controller for input and output signal cable to the connector on the controller, shall not lead directly on receipt of the controller. Input and output signal line terminals should be clearly marked and numbered to track inspection, repair and replacement. ② focus fire alarm controller should be set to be on duty room or fire control rooms. Control room watchkeeping personnel should go through the local fire department training certificates. 　　③ focus fire alarm controller connected zone fire alarm controller should meet regional requirements for fire alarm controller. 3. Control Center alarm system control center alarm system is set up in fire control room fire control equipment, central fire alarm controller, regional fire alarm controller, fire detectors and manual fire alarm button, such as the composition of the complex functions of automatic fire alarm system.　　One of the main fire control equipment, including fire alarms, fire call, fire emergency lighting, fire emergency broadcast, smoke control, ventilation, air conditioning, fire service lift linkage and fixed fire extinguishing systems of control devices. Control Center alarm system should be designed to meet the following requirements. ① system at least has a central fire alarm control unit, a special fire control and two or more regional fire alarm controller.
