1. The choice of the form of automatic fire alarm system shall comply with the following provisions: 1. The protection object that only needs to alarm and does not need linkage automatic fire fighting equipment should adopt the regional alarm system. 2. Not only alarm is needed, but also linkage automatic fire control equipment is needed. Only one fire alarm controller with centralized control function and protection object of fire control linkage controller should be set, and centralized alarm system should be adopted, and a fire control room should be set. If two or more objects of fire control room protection are set, or two or more objects of centralized alarm system protection are set, the alarm system of control center should be adopted. Description: the form and design requirements of automatic fire alarm system are directly related to the object of protection and the establishment of fire safety objectives. The correct understanding of the process of fire occurrence and development is very important to the design of automatic fire alarm system. The selection and design requirements of fire automatic fire alarm system are given. In today's "people-oriented, life first", the first task of building fire protection system is to ensure personal safety, which is the most basic concept of fire protection system design. From the basic concept, and will come to the conclusion that: early detection of fire and timely alarm, start guide evacuation and fire control facilities, and during the evacuation, if the degree of development to need to start the automatic fire extinguishing facilities, corresponding automatic fire extinguishing facilities should be qi gong, put out a fire early, to prevent the spread of fire. After the automatic fire extinguishing system was activated, the survivors of the fire had to rely on the help of fire rescue personnel to escape. Because the fire development to this stage, the stranded personnel due to the gas, high temperature and other reasons have lost the ability to escape. This is also the basic meaning of several fire-fighting processes related to fire. There is also a personnel evacuation stage between fire alarm and automatic fire extinguishing, which varies from a few minutes to dozens of minutes depending on the location of the fire, the cause of the fire and the combustion material. This is the most important stage directly related to personal safety. Therefore, in any place where personal safety needs to be protected, setting up automatic fire alarm system has irreplaceable significance. Only when an automatic fire alarm system is set up can an organized evacuation be formed and an emergency plan be made. The fire location determined is the starting point of the evacuation plan. Evacuation refers to the behavior of organized evacuation from dangerous places according to the predetermined plan. The behavior of leaving dangerous places without organization can only be called escape, and cannot be called evacuation. After evacuation, only when the fire has developed to a certain extent can the automatic fire extinguishing system be started. The main function of the automatic fire extinguishing system is to extinguish the initial fire and prevent the fire from spreading and spreading. It cannot directly protect people's lives and cannot replace the automatic fire alarm system. Automatic fire alarm system also plays an irreplaceable role in the protection of property. The use of high-rise buildings, super-high-rise buildings and large-volume buildings with complex functions will cause major property losses in case of fire due to the high risk of fire. Protection object to store important substance, severe pollution and exert agent after burning lead to loss of material value, these places should be within the protection object set fire warning system, in front of the fire, the signs of the detection may cause fire characteristics, thoroughly to prevent fire or small fire before it in a timely manner by the police. Electrical fire monitoring system and combustible gas detection and alarm system are fire warning systems. Therefore, the safety target is directly related to the choice of the form of automatic fire alarm system. The regional alarm system is applicable to the protection objects that only need alarm and do not need linkage automatic fire fighting equipment. The centralized alarm system is suitable for protection objects with linkage requirements. Control center alarm system generally applicable to buildings or mass great protection object, the protection of objects may be set in several fire control room, may also be due to the installment construction USES the product or the same enterprise in different enterprises of different series of products, or due to the system capacity restriction set up multiple fire alarm controller, etc., in one of the focus on these cases should be choose alarm system control center. The design of the regional alarm system shall comply with the following provisions: 1. The system shall consist of a fire detector, a manual fire alarm button, a fire audible and visual alarm and a fire alarm controller, etc. The system may include a fire control room graphic display device and a floor area display. The fire alarm controller should be set in the place where someone is on duty. 3 when the system sets up the graphic display device of the fire control room, the device shall have the function of transmitting the relevant information specified in appendix A and appendix B of this specification; If the system is not equipped with graphic display device of fire control room, fire alarm transmission equipment should be set. Description: this article provides for the minimum composition of an area alarm system, which may be equipped with a graphic display device in the fire control room or an area display indicating the floor as required. The regional alarm system does not have the function of fire linkage. In the zone alarm system. No fire control room can be set according to the need. If there is a fire control room, the fire alarm controller and the graphic display device of fire control room should be set in the fire control room. If there is no fire control room, it should be set in a room or place with a special person on duty at ordinary times. The regional alarm system should have the function of transmitting the relevant operation status information to the urban fire control center. The design of the centralized alarm system shall comply with the following provisions: 1. The system shall be composed of fire detector, manual fire alarm button, fire audible and visual alarm, fire emergency broadcast, special fire telephone, fire control room graphic display device, fire alarm controller, fire control linkage controller, etc. The fire control equipment which plays the role of centralized control, such as fire alarm controller, fire control linkage controller and graphic display device of fire control room, control device of fire emergency broadcast, special telephone switchboard for fire control, shall be set in the fire control room. The graphic display device of fire control room set up by the system shall have the function of transmitting the relevant information specified in appendix A and appendix B of this specification. Description: this article provides for centralized alarm design. 1 the minimum composition of a centralized alarm system is specified in this section, in which a combination of fire alarm controller and fire control linkage controller or fire alarm controller (linkage type) can be selected. 2. This clause stipulates that fire control equipment which plays the role of centralized control in centralized alarm system, such as fire alarm controller, fire control linkage controller and graphic display device of fire control room, control device of fire emergency broadcast, special telephone switchboard for fire control, shall be set in the fire control room. In the centralized alarm system, the graphic display device in the fire control room is the necessary equipment, so it can transmit the relevant information. The design of the alarm system in the control center shall comply with the following provisions: 1. When there are two or more fire control rooms, one main fire control room shall be determined. 2. The main fire control room shall be able to display all fire alarm signals and linkage control status signals, and shall be able to control important fire fighting equipment; Each sub-fire control indoor fire fighting equipment can transmit and display status information to each other, but should not control each other. The graphic display device of fire control room set up by the system shall have the function of transmitting the relevant information specified in appendix A and appendix B of this specification. Other designs shall comply with article 3.2.3 of this specification. Description: objects protected by two or more centralized alarm systems or two or more fire control rooms shall adopt the control center alarm system. For protection objects with multiple fire control rooms, a main fire control room should be determined to manage other fire control rooms. Define the level of the fire control room according to the actual use of the building. The main fire control palace should be able to display all the fire alarm signals and linkage control status signals in the protected object, and display the status information of fire fighting equipment set in each sub-fire control room. In order to facilitate the information communication and information sharing between the fire control rooms, the fire equipment in the sub-fire control rooms can transmit and display status information to each other. At the same time, in order to prevent the conflict between the fire control equipment of each fire control room, it is stipulated that the fire control equipment of the sub-fire control room should not control each other. In general, the water pump and other important fire-fighting equipment commonly used in the whole system can be controlled by the highest level fire-fighting control room according to the management requirements of fire-fighting safety and the actual situation. In the alarm system of the control center, the graphic display device of the fire control room is the necessary equipment, so it realizes the transmission function of relevant information.
