"Fire alarm" into the family note four anti-counterfeiting

From Tianjin Municipal Public Security Fire Department to understand, according to the Ministry of public security, the State Administration for Industry and commerce,State Quality Inspection Administration "on the fire product quality of the work of special rectification notice" requirements, cooperate fully with the fire safetyinvestigation and remediation activities, strictly the purifying fire product market, crack down on fake fire products, from now until mid November, Tianjin city fire departments will be combined with the Municipal Public Security Bureau, the city administration of industry and Commerce and the city quality inspection bureau and other departments,the construction project using the fire product quality supervision and spot checkscarried out the action. The main products have been entering the construction and installation of fire and will be put into construction project acceptance in the fire alarmdevice (point type smoke fire detector, point type heat fire detector, manual fire alarm button, fire hydrant button), fire water supply equipment (indoor fire hydrant, fire hose) (lined fire hose), fire fighting equipment (DC gun), fire extinguishers (portable dry powder fire extinguisher), exhaust device architecture (fire damper, exhaust valve), evacuation device (fire emergency marker lamp, fire emergency lighting),sprinkler equipment (sprinkler) are 8 kinds of fire product quality supervision.

In the high-rise building people working or living on the head that or circular, or square "fire alarm" is not unfamiliar, but after that visit, many people on the "firealarm" exactly is what to do with, how to protect the little we safety knowledge, as "just a display". The following will provide you a detailed interpretation about "fire alarm".

The fire detector: will be affected by the accumulation of dust pollution effect

The fire detector is the fire of automatic fire alarm system, to detect the site, it is found that the fire equipment, is a system of "sensory organs". It is the role of occurrencemonitoring environment there is no fire. Once there is a fire, the fire characteristics ofphysical quantity, such as temperature, smoke, gas and radiation into electrical signal,and immediately send the alarm signal. The fire detector can be divided into thesmoke detector, temperature detector, smoke temperature sensitive composite type fire detector and gas fire detector. At present we use most is the smoke and fire detector, to control the warning at one point in the temperature, smoke and other parameters.

Firefighters, fire detector is composed of automatic fire alarm system core component,is a modern fire alarm and automatic fire extinguishing system is an indispensable part, its working condition directly affects the normal operation of the whole disaster prevention system. Firefighters remind, affected by environmental factors such as the accumulation of dust and oil, fire detector reliability is greatly reduced, or even falsefalse alarms caused by phenomena have occurred, the need for timely cleaningrepair.

Make clear provisions on the inspection and testing of fire detector and cleaning in the "code for construction and acceptance of automatic fire alarm system": action and confirm the lamp 1, each quarter using the special detecting instrument installmenttest detector display. 2, every year in the special detecting instrument for theinstallation of a detector test. 3, the fire detector is put into operation two years later,should be every three years all clean again, and make a response threshold and other necessary function test, eligible can continue to use, unqualified person is strictly prohibited to re install.

Combustible gas detectors: City gas safety finally "barrier"

In order to fire detector image area look different "" and "combustible gas detector",firefighters that: "fire detector" is more focused on the fire alarm, dangerous and"combustible gas detector" more focused on fire just before the detection alarm.Combustible gas alarm is gas safety equipment is very important, it is the last protection and safe use of city gas. When the environment flammable or toxic gas leakage, gas alarm detect gas concentration reaches the critical point explosion orpoisoning of alarm settings, gas alarm will be issued a warning signal, to remind thesecurity measures, gas alarm is equivalent to the class of automatic fire extinguisher,can drive the exhaust, cutting, spray system, to prevent an explosion, fire, poisoning,to guarantee the safety of production, life safety. With the development of the plots ofresidential construction, high-rise, intelligent and pipeline gas popularization, the continuous improvement of the socio-economic level, national and local development of some building code for fire protection design and intelligent building codes, which have promoted the use of combustible gas detector.

Fire fighting personnel introduces, combustible gas detector for carbon monoxide alarm, the concentration change of carbon monoxide gas carbon monoxide sensor in the air into an electrical signal, the signal with the concentration of carbon monoxide.Generally divided into semiconductor carbon monoxide alarm, carbon monoxidealarm, infrared carbon monoxide detector etc.. The semiconductor carbon monoxide alarm general service life of up to five years. The use of electrochemical carbon monoxide alarm in air is generally three years, also have five years longer, up to eightyears.

"Fire alarm" into the family note four anti-counterfeiting

Fire personnel introduces, now, "fire alarm" is gradually into the homes of ordinary people. The household type smoke detector for example, also called independenttype smoke detector, is generally used in the home, do not need to connect thesystem can realize independent detection, independent alarm. In the market generally
