High-rise Building Fire Alarm Control System Design And Applications - High-rise Buildings, Fire
Abstract: Conventional fire alarm system suitable for medium and small buildings
, it is characterized by the threshold detector is based, the controller only host one. The intelligent fire alarm control systems, using analog detectors, the control system uses the master? From the network structure, adaptability, especially for large-scale building fire alarm system. Intelligent fire alarm system, to overcome the traditional fire alarm system false negative and false positives existing problems, improve warning accuracy, reliability. Flexibility in design applications, according to project need to select the appropriate number from the machine, so that the project design the most economical and reasonable. In order to take preventive measures, fire alarm system design and application is important, designers should be based on different construction projects, optimization of design.
Keywords: control system design applications high-rise building
With the development of China's economic construction, modern high-rise buildings and important buildings caused the fire problem and Design Institute and other state fire departments attach great importance to the community. Countries to develop a series of fire safety, fire alarm equipment to facilitate research and promote the use of. Large-scale high-rise building construction, renovation of high standards, staff-intensive, frequent use of various electrical equipment, so there are fire hazards, electrical design in the construction specifications must be strictly in accordance with the design of fire alarm control system. But the choice of control systems, to make the system function fully and effectively, is a very important design issue.
1, the main fire alarm system components and features
Automatic fire alarm system, there are three basic forms, namely: regional alarm system, central alarm system, alarm system control center. High-rise buildings and large construction mainly alarm system control center, which is a complex fire alarm system, mainly by the trigger devices, fire alarms, fire control equipment and power supply component. The system to start fighting the fire from the communications system and control fire-fighting equipment, basic automation.
Trigger devices include fire detectors and manual fire alarm button. Fire detector is the fire parameters (smoke, temperature, light, flame radiation, gas concentration, etc.) response, and automatically generate a fire alarm signal devices. Fire response parameters according to different fire detectors into heat detectors, smoke detector, gas fire detectors, fire detectors and light-sensitive compound five basic types of fire detectors.
Fire alarm device in automatic fire alarm system to receive, display and transmit fire alarm signals and control signals, and can occur with other auxiliary functions of the control target device.
Fire alarm device in automatic fire alarm system to send different from the environment, sound, light the fire alarm signal devices, such as fire alarms, it is a basic fire alarm device to sound, light and sound way Police issued a fire alarm signal region.
Fire control equipment, automatic fire alarm system when received from the trigger parts of the fire alarm signal, automatically or manually start the relevant fire service installations and displays the status of the device. Include: fire alarm control; automatic fire extinguishing system controls; indoor fire hydrant system control unit; smoke control system and control device for air conditioning and ventilation systems; often open fire doors, fire shutter control device; elevator back down control devices and fire emergency radio, fire alarms, fire communications equipment, fire evacuation signs and emergency lighting control device control device such as 10 classes. The needs of each system should be based on the engineering class of control device 10 of some or all. Automatic fire alarm system
power electrical equipment belonging to the fire, the main power supply with fire power, with battery backup power to ensure uninterrupted power supply.
Design fire control equipment installed in the main fire control center, to facilitate the implementation of centralized control, some of fire control equipment can be installed in fire-fighting equipment on site, while the movement signal to return to the fire control center, combining centralized control mode and scattered .
