1. System design Wing Chong Xian audio technology company Contact: Mr. Chen 13359212048 qq: 58661261 in strict accordance with automatic fire People's Republic of China Ministry of Public Security alarm system design specification (excerpt) (GB50116-98) as a design basis, with the needs of your side with the best design reflects the highest price-performance, function and indicator systems to achieve the same type of advanced system of ranks, it is our overall design. Embodied in the following areas: 1) advanced and scalability: The development of modern information technology, new products and new technologies. Therefore, this system in the case of investment costs in the permit should take advantage of the latest modern technology to make the system as long as possible the time and social development to adapt. However, due to the rapid development of modern science and technology, we must fully consider the future development needs, the design must be proactive and scalability. This scalability not only fully protect the investment Party, but also has a higher overall cost performance. The design of this have been fully considered, embedded the necessary pipeline, set aside a variety of interfaces, very easy to expand and upgrade the system. 2) scientific and normative: public broadcasting system and the general sound systems, is an advanced integrated complex systems engineering, must start from the system design, including the construction, installation, commissioning until final acceptance of the entire process, in strict accordance with the national relevant standards and norms, good standardized design system and scientific management. The last report submitted to the formal acceptance test and a full set of construction drawings and technical data for the Party archives. The main normative content perform include:??? GB50116-98 "automatic fire alarm system design specification (excerpt)" GJG / T16-92 "civil electrical design specifications" GB / T50314-2000 "Intelligent Building Design Standards" 3) Safety Reliability and: public broadcasting system of the building, directly affects the user's results, external image and return on investment, so the system design must be safe, reliable, and this program has been fully considered mature technologies and products, equipment selection and design of the system to minimize the occurrence of failure. And in terms of laying lines, equipment installation, commissioning and technical training to the Party personnel, etc., shall meet the requirements of reliability. It is particularly important that all major key equipment of the program of choice, by the Division I draw current advanced technology domestic public / fire radio system, developed and produced out of professional public / fire radio system, it is the international and domestic construction tenders One key focus of the assessment of the conditions. This design is based on the requirements of Party, absorb advanced technology integrated current domestic public / fire radio system, is designed to advanced equipment, elegant, beautiful sound, fully functional modern public / fire radio system. The configuration of the device are selected OPLL (Opie) brand products to ensure superior performance. We are engaged in the use of systems engineering design and construction for many years of theoretical and practical experience, careful combinations, ensure excellent performance, reliable quality. The following are public / fire radio system is designed to make a brief description of each. Public / fire radio design specifications:? Automatic People's Republic of China Ministry of Public Security fire alarm system design specification (excerpt) (GB50116-98) 1999 年 6 月 1, 2008.) control center fire alarm system should be set up emergency broadcasting, centralized alarm system should be set up fire emergency broadcast. ? Fire emergency radio speaker setup should meet the following requirements:? Civil loudspeaker should be set in the lobby and other public spaces and walkways.

In the ambient noise of more than 60 speakers place set within its broadcast range farthest point play sound pressure level should be higher than the background noise of 15. ? Room Set sound for speaker, its power is not less than 1.0W. ? When the fire emergency radio and public broadcasting in combination, should meet the following requirements:? Fire in the fire control room should be able to fire evacuation layers speakers and public address megaphone forced into the fire emergency broadcast state. ? Fire control room should be able to monitor the operating status of the amplifiers when the fire emergency broadcasting, and should have a remote control to open and use the microphone megaphone broadcast function. ? Bedside control cabinet music radio speaker with a service, there should be a fire emergency broadcast function. ? Should set fire emergency broadcast spare amplifiers, 1.5 times within its capacity is not less than the fire to simultaneously fire emergency broadcast radio speaker sum of the maximum capacity. Services Xi'an, which sells sound stage, campus radio, hand in hand conferencing systems, professional audio, background music, our products are OPLL Opie Northwest distributor, S-MAKE, Haitian and other equipment, to welcome you contact application company :( residential areas, hotels, shopping, supermarkets, schools parks, squares, stations, terminals, tourism and leisure area, park area, entertainment centers, restaurants teahouse, office buildings, factories and enterprises, hospitals, auto 4S shops, clothing stores, departments and units , prisons, water electricity, banking and mining enterprises) and other enterprises; Uses and Features: The main role is to play background music and radio programs, masking noise and create a relaxed and harmonious atmosphere of the music. Therefore, the effect of background music are the two psychological cover environmental noise, and the second is to create the atmosphere of the indoor environment to adapt in recent years, public broadcasting system also doubles as an emergency broadcast, with the fire alarm system linkage. Control public broadcasting system more. As with all call constituency broadcast broadcast function, forcing the power switching function and priority broadcasting rights functions.
