Automatic Fire Detection Technology In The Development History And Trend Of - Fire Detection, Fire
Fire detection industry is rapidly changing, however
, technological change does not necessarily mean that better fire protection system. Data logging and system capacity improvements and reduce maintenance requirements in the foreseeable future for some time, will not lift maintenance engineer to the site to see the need. Now there fire safety equipment, the pace of change will adversely affect the quality of the risk. For example, now, some detectors, and cable is used although cheaper, but do not have the fire performance of materials do.System Design Guide In the early stages of system design, few consider the protection of specific people and things. Mainly relies on a sense of moderate fire Smoke Detector Moreover, legislation in this area is very loose. For example, the regulations, while providing the maximum interval between the detector, but the protection of life or property of the system requirements there is no real distinction. Now, the British Standard BS5839 basic fire detection Part 1 provisions and the distinction between life and property protection.
Construction industry has undergone an obvious change, are now used to make the best of the large glass building structure lighting, heating and complex Ventilation Systems and innovative ceiling and roof, far beyond any suitable definition of the standard interpretation. In order to reflect the fire detection and alarm system on the new technology, BS5839 Part 1, respectively in 1988 and has recently made two amendments. Now, the system's components and design, while more advanced than before, but, with the installation Environment And construction of the combination does not close, or not to consider changes in construction techniques. To address these shortcomings, the British Standards Institute is currently reviewing the standards, and some organization and preparation for detection of specific applications and air flow problems. In fact, the need for an alarm company to continue development environment for building features and performance-based specifications.
European standards can not give specific applications on the design information needed, so the professional company to be the first to undertake this task, even simple structures require the application of advanced technology to provide reliable and cost savings. Many fire companies will continue to strengthen the study of complex systems, but they can not be solved technologically advanced fireproofing systems knowledge and skills.
Aspirating detection system 50 years in the 20th century, the basic form of suction-type detectors have been there, but did not achieve widespread credibility, until the 60's and 70's. Recently, there has been very high sensitivity of the aspirated detectors, but the absence of appropriate standards to facilitate its application, its application is not very satisfactory. Given this situation, the British Fire Protection System Association under the system of production, design and engineering experience, developed a guide to practice very practical norms. Can be expected, suction-type system will provide the best detection of the specific applications play a growing role. Application of suction-type system suitable for the protection of special places with the prison dormitories, beautiful landscape construction, high-pressure chamber, microwave transmitter sites, sealing, or "clean" rooms, shielded rooms, Faraday cage. Suction-type system in the hidden room, can not maintain the application of the region may have great and growing.
UK Loss Prevention Council (LPC) certification of fire detection and alarm company's plans LPSl014, will ensure that these systems have the same performance with its design.
Installation
In the past, the system is because the installation of a lack of test standards inconsistent and unreasonable. Now, the system uses LPSl014 quality is improving. Certified, the company allowed itself to paying attention to the implementation of standards to achieve a higher installation design qualification, and to avoid the penalty caused by unqualified. Through the application of LPSl014, many standards, including BS5839 Part 1 have been revised and enforced. At the same time, also requires the installer to accept LPSl014 audit and conduct formal training. Prompted the company to improve the quality of the environment according to the system a better choice of detector applications, so the system has fewer false positives.
