【 Weak current College 】 smoke cleaning quality supervision of

Along with the relevant fire laws and regulations of the health and social importance of fire safety work, construction (construction) construction of commonly installing an automatic fire alarm system, fire prevention and extinguishing fires in time provides important protection. Automatic fire alarm system installed to use after regular maintenance and upkeep. Fire detector cleaning is the automatic fire alarm system of maintenance of an important component. At present, except in some areas, fire supervision agencies on smoke cleaning cleaning enterprise management, cleaning qualification certificates, other areas have not yet been carried out this work. Therefore, cleaning work is still in the smoke-free status of the order, not normative, cleaning quality and good fun not qi cannot be guaranteed.

I. strengthening the smoke of the importance of the cleaning quality supervision
Fire detector for people running vulnerable to pollution, the accumulation of dust, reducing the reliability, false positives or false negatives. Therefore, after the installation and use of fire detectors must be periodically cleaned. Fire detector for cleaning different from mechanical product and General electronic products of cleaning, this is a technical and technological requirements are very high, it requires close to probe manufacturing quality assurance system and good production environment conditions, advanced cleaning technology and equipments, complete testing instruments and testing equipment. Smoke sensor cleaning quality directly affects the quality of the entire system, that system's reliability and false positives.
According to statistics, in the use of point-fire detectors have 30 million each year, only needs to be cleaned of detector approximately 10 million, therefore fire detectors cleaning business volume is very large. Although GB50166 a 92 the automatic fire alarm system construction and acceptance of the fire detectors clearly stipulate, as users, producers and fire monitoring bodies are not sufficient to smoke, fire and supervise cleaning agencies do not have operational supervision of the management approach and effective quality control, so that users do not know how to select a detector cleaning units, production enterprises according to their convenience of deciding whether to probe cleaning, while most cleaning Enterprise for lack of funds, personnel, environmental, technical conditions limit cannot guarantee the quality of the probe cleaning. So after cleaning the effective operation of the detectors? fire such timely alarm fire safety facilities can safety is, therefore, the author believes that the fire detector cleaning quality supervision and regulation is necessary and urgent need.

Second, the smoke cleaning should take measures of supervision and management
Current fire detector cleaning business model there are two. One is the detector manufacturers the products of this company as an element of the after-sales service for cleaning, this is a large detector manufacturers take cleaning mode; another is specialized in smoke cleaning company, cleaning it is for many companies, including the production of domestic and imported products, this mode uses more of.
1, strict fire detector cleaning Enterprise qualification criteria
Engaged in the cleaning business enterprises must have legal personality, in sites, facilities, environmental protection, personnel protection, etc., should be consistent with the provisions of the relevant departments. Cleaning business site selection, plant layout, storage requirements should be similar to the production enterprises should be spacious, bright, clean, temperature and humidity can be effectively controlled with measures against static electricity, etc. Cleaning enterprises should have the fire detector cleaning to adapt to the size of the device, such as: fire detector module, chip, circuit board cleaning equipment, cleaning equipment, shell, electric oven, anti-static equipment, waste water, exhaust gas treatment system and laboratory analytical instruments, radiation detection instrumentation and calibration equipment for response and close values (smoke box, warm box), and cleaning fire detector types of testing, calibration equipment, special equipment for Assembly and disassembly of the radioactive source tablets, as well as other devices should be fitted. Cleaning the waste processing enterprises should be consistent with environmental protection requirements, the cleaning process on the protective measures taken should be consistent with the labour protection and environmental protection requirements.
2, should establish a comprehensive quality management and quality assurance system
Cleaning enterprise quality system should undergo IS09000 certification. After cleaning the fire of fire detectors by the supervisory bodies of the sampling to national fire products quality inspection agency inspection, cleaning enterprises to engage in fire detectors cleaning. Fire fighting supervisory body in each of its quality assurance system and cleaning products quality supervision and inspection. The cleaning of the detector after installation, you should debug only one by one. Detector and alarm system debugging should be the appropriate qualification units.
3. cleaning enterprises should have and related detector manufacturers signed agreement of entrusted cleaning
Cleaning the content of the agreement for the delegate should include the following:
(1) production enterprises entrust cleaning of detector name, model number;
(2) the manufacturer shall provide the technical support and spare parts for the paid provided the detector, and for verification of controllers, etc.;
(3) the manufacturer shall provide the detector needs cleaning, repair or scrap detection and judging criteria. Cleaning is in the probe or module, and other accessories not damaged under the premise of dedusting, calibration and other electrical parameters adjustment process; maintenance is the product of the components or part damage is not working properly, you need to replace components or parts; detector of scrap is already not working properly for scrap, ion sensing smoke detector recycling and disposal of radioactive devices. Clear the cleaning company, cleaning and scrap for maintenance by the manufacturer;
(4) cleaning enterprises should save probe cleaning procedure of quality records
And after cleaning to record the installation of acceptance;
(5) the agreement should specify quality accident occurred after cleaning, the cleaning of production enterprises and enterprises in their respective share of the responsibility of quality;
(6) cleaning enterprises production enterprises to provide technical support for confidentiality commitments;
(7) the Protocol is not negotiated by the parties.
4. cleaning cycle
Detectors for people 2 years running, you should first cleaning, cleaning every three years thereafter. Special places such as tunnels, the kitchen, the boiler room cleaning time can reduce the detector for cleaning once every year; public entertainment, severe dust, smoke contamination of sites, subway and largeUnderground shopping malls and other cleaning cycles to clean 1-2 years.
5, the layout of the smoke feeling cleaning enterprises should be reasonable
Beijing, Shanghai, Tianjin, Chongqing, Shenyang, Guangzhou and other cities have cleaning Enterprise 3 ~ 6, the capital city there are 2 ~ 3, municipalities can have 1 to 2. Actually fire detector cleaning work was mainly concentrated in large cities, from macro-and fire supervision perspective the market should guarantee the quality and users limited development, the development of a mature one, should not blindly.
6, one of the following, no cleaning of detector should use
(1) original production enterprises has been closed down and transferred or has eliminated such a detector to provide the spare parts,
(2) automatic fire alarm system has been paralyzed or one year cumulative deactivate three months to replace the probe still does not function properly;
(3) import detectors of plant names, brand names and associated information is incomplete or spare parts supply cannot be guaranteed.
Fire departments responding to the relevant units or individual supervision, deadline Update entire fire alarm system or probes.

3. fire detector after cleaning the responsibility of quality
Smoke after cleaning the responsibility of quality is not clear, it is easy to result detector manufacturers and cleaning Enterprise push each other. In my view, the detector probe cleaning production enterprises and Enterprise commissioned cleaning contract, probe after cleaning quality rests with the detector production enterprises. Because the probe cleaning is authorized by the manufacturer, the manufacturer gives technical support and guidance, part of the production company after-sales service. User should direct accountability for the quality of the production enterprises or request payment and cleaning enterprise should assume responsibility for the quality and economic compensation, according to the cleaning enterprises and production enterprises signed contracts to determine commissioned cleaning.
For non-production enterprises unauthorized conduct smoke cleaning the quality responsibility, it should be borne entirely by the cleaning companies. This is because on the probe casing, chip, circuit, such as cleaning, drying, a response value test functions such as aperture, will cause fire detectors part performance changes. At the same time, I also think that smoke after cleaning should also be affixed with uniform cleaning flags to be traced back if a problem occurs.
IV. fire reported for product life span and spare save life
1, fire alarm service life of the product
At present, China's design specifications and product standards do not require fire detectors of life, according to the technical development of electronic products, technical updates, and the fire alarm products use capacitors and other components aging period, it is recommended that the possibility of fire alarm product service life for 10 years. For explosion-proof areas, marine sites use fire alarm products should have a mandatory retirement age, and other places used by the fire alarm products should be recommended for scrap.
2. fire alarm products spare save life
Because of the automatic fire alarm system is composed of fire detectors, fire alarm and fire alarm equipment, common, each automatic fire alarm system needs to have a certain number of component spare parts replaced, otherwise the entire system will be unable to run efficiently, you can only update. Therefore, the fire service industry management departments dealing with national production enterprise in unified fire alarm products spare save time, and the fire alarm product service life of 10 years, that is, unity of production enterprises should provide fire alarm product sales after 10 years of technical support.
