<br> <br> To prevent and reduce fire hazards, and give full play to building fire facilities disaster prevention and mitigation of effects, ensure that the building fire safety, under the FPPA People's Republic of China, Ministry of public security 1996 Decree No .. 30 on fire supervision of the construction work and audit management gongtong Word text no. 21 of 1996 on stepping up and earnestly implement fire inspection maintenance management system of notification of requirement established technical fire-fighting facilities at 400-670-0020 detection system. .Beijing city fire station on the fire facility of technical inspection, fire-fighting facility certification (Licensing) of notices, notices that: where a new extension building, rebuilding, after the completion of the construction works, building fire facilities put into operation before detection .by the bodies eligible for technical testing, after passing by the firefighting agencies for acceptance, acceptance issued fire facilities certificate (card). Without detecting or measuring not qualified engineering, fire agencies are acceptance shall not be put into use. For live fire facilities implement .periodic inspection system. Where in the city administrative region building fire facility yearly fire detection. <br> First, the client should prior agreement the content detection, time and space, and the signing of the memorandum of agreement on testing. <br> Second ., the client shall provide relevant information, such as drawings, acceptance project (fire review submissions), records, and other concealed works. <br> 3. detecting party principle operations client facilities, if necessary, the required client side with the relevant personnel .. <br> IV. client side detection results if there are objections to field repetition, confirmed in test records. <br> 5. after the end of the testing of three working days of issuing the examination report. <br> Electrical fire safety .inspection of the condition, means and content <br> First, the basic electrical fire detection conditions <br> 1, should be in the electrical installation and wiring with 1n above-load operation, on entering the heat-stable State for detection and measurement .. <br> 2. should the client side for technicians on site support. <br> Second, the main electrical fire detection tools <br> The use of modern high-tech equipment, such as infrared thermometer temperature measurement, infrared TV scan, .infrared camera shoot hot spectrogram and the use of ultrasound detectors measuring abnormal temperature, spark discharge and other phenomena and use conventional electric instruments, instruments such as voltmeters, ammeters, electroscope, grounding resistance tester, TRMS ampere meter, etc, on the operation of the .electrical facilities of various operating parameters for measurement and use of Visual methods, control the relevant technical specifications, to run in high-voltage electrical equipment installation, use, maintenance, and maintenance of electric fire detection. <br> 3. check (logging) .<br> 1, the transformer room <br> ① Visual inspection of the set transformer room location, fireproof grade and hole sealing; transformer set, Visual quality, components, integrity and fire prevention measures; high-voltage cable (wire) installation, .etc. <br> ② with infrared series instruments detect the level transformer and cable (wire) contact temperature and beat the heat map. <br> 2, high (low) voltage distribution equipment <br> ① Visual inspection, high (low) .pressure distribution equipment settings, installation quality, inside wiring, high (low) voltage cable (wire) connector, complete grounding, accessories and fire prevention measures, etc. <br> ② with conventional Instrumentation (or read) the line voltage (flow) .value, N lines of unbalanced current values, there is no exception PE line current and resistance values, etc. <br> Û infrared series instruments measuring wire and connection points, switch contact temperature and beat the heat map. <br> 3. low .-voltage power distribution box (spare) <br> ① Visual inspection distribution box (spare) settings, material quality, installation quality, inside wiring, wiring terminal connection, Earth and fire prevention measures, etc. <br> ② with conventional instruments measuring .load current value, N line current value and there are no exceptional PE line. <br> ⑶ infrared series instruments measuring box (spare) in the Terminal, the circuit breaker contact temperature and beat the heat map; the use of ultrasonic detector measurement has .no spark discharge phenomena. <br> 4. laying low-voltage distribution lines <br> Check the different places of power concealed, downlead, direct deposit and wear protection pipe line in the installation of electric fire hazard. <br> 5, electrical .lighting <br> Check the different places with electricity, a variety of lighting equipment in the installation of electric fire hazard. <br> 6, switch, socket <br> Check in different places of installation of electricity, use of switches, outlets, .electrical fire hazard exists. <br> <br> Fire facilities detection content <br> First, the automatic fire alarm system <br> 1. detection of automatic fire alarm system wiring insulation resistance, resistance, system grounding, pipeline installation and its protection .status; <br> 2. detection of fire detectors and alarm button settings, installation quality, protection RADIUS and surrounding Occluder distance, etc., and by 30 ~ 50% proportional sampling its alarm function; <br> 3. detection of fire alarm .controller installation quality, inside wiring, protection, earthing and standby power settings, the settings and transformation capabilities, and controller functions test; <br> 4. detection of fire-fighting equipment control cabinet installation quality, inside wiring, hand, automatic control and .the Panel accepted firefighting equipment signal feedback function; <br> 5. detect elevator landing capabilities, fire elevators feature, cut off the non-fire-power functions and burning layer light display; <br> 6. detection of fire control room, the .fire protection equipment and fire hydrant button Office communication; <br> 7, testing fire emergency broadcasting of audio features, manually selected layers and automatically broadcast, remote controlled opening and forcibly switches, and other functions; <br> 8. detecting fire control room .set location and clearly marked, indoor fire damper and independent pipeline set, double-circuit power settings and switching; <br> 9, detection of fire emergency lighting and evacuation signs set, illumination, conversion time and graphic symbols; <br> Second, .the fire serviceSystem <br> 1. check the nature of the fire water sources, the number of pipes and the diameter of the fire pool settings; <br> 2. check the fire water tank volume, water level indicator and water facilities, ensure .fire water and frost protection measures; <br> 3. check the settings of the fire water tank, capacity, antifreeze, water and the State of the check valve; <br> 4. detection of various fire pump performance, pipes, hand control ., start time, and reserve and standby pump and power conversion functions, etc.; <br> 5. detection combined with the pump set, signs and conveying fire-fighting water features, etc.; <br> 3, indoor hydrant system < .br> 1. check the indoor hydrant installation, 0 components, specifications and spacing, etc.; <br> 2. test the settings, the roof of a fire hydrant frozen Chan and enrich the water column length measures, etc. <br> .3. check the settings of the indoor hydrant pipeline, pipe diameter, colors, ensure fire water and connect shapes; <br> 4. detection of the first floor indoor hydrant and the most negative point of static and dynamic pressure and enrichment of the water .column length; <br> 5. check the manually restart the pump button's settings and functions;
