Discussions about the new national standard

1, the new "standard" terms, clearly express the concept of "fire emergency lighting" as: including evacuation floodlight lighting and fire control work;Indicating lamp in addition to retain the original connotation, increased the floors, the refuge floor light, classification of increased the fire emergency lighting (marks) a composite form of lamps and lanterns, the expansion of the connotation in order to the future in the engineering design is I add clear fire emergency light use situation and characteristics of easy to design specification in the future;Increase the compound type of emergency lamps and lanterns, have already had this kind of type is due to the actual product, but to live in a part in the practice of engineering design, construction and use of personnel lacks the understanding to this, in fact marker light stressed for the surface brightness, according to the evacuation according to not make the request.Such as electroluminescent screen class emergency lights can only conform to the requirements of the marker light but not enough brightness.Using the fluorescent emergency lights, such as converting low brightness, also only can be used as a marker light.Only conform to the requirements of the marker light surface brightness, together with sufficient convert luminous flux, and can make the ground produces in the structure of a certain intensity of illumination lights to meet fire sign display and the role of evacuation lighting, otherwise it shall furnish the evacuation lighting.


2, about the lash type power supply, centralized control and centralized power type, language DiShiXing, shiny and successive ablaze with fire emergency lamps and lanterns, are the original no or just mentioned in the "standard", but existing in practical application, increase and add this part is very necessary.


3, all about symbol lamp surface level of color, brightness and brightness than the relevant provisions, only mentioned in the standard of the highest and lowest luminance requirements and the highest and lowest luminance proportion, give full consideration to the our country at present more popular in the new standard of electroluminescent emergency lights are of this kind of special, and refer to the latest international standard version, set the color of the logo information, to norm of different type of marker light surface brightness lowest and highest limit and the brightness difference between the itself;Given a different color than the brightness of the border between adjacent points.These rules are in order to ensure the lights in the application is not caused by high brightness and adjacent contrast is too big glare.To avoid the same color between adjacent color brightness than too big or size and appear vague and affect vision.


4, increasing the high-risk area with fire emergency lights, and determine its emergency conversion time is 0.25 S, is based on the practical application in some occasions, such as high speed machine tools, escalators in the mall, in the normal lighting after resection, appear easily dangerous state.These occasions to shorten emergency conversion time from 5 S to 0.25 S, is in conformity with the actual situation need, at the same time also in conformity with the relevant IEC standard.High-risk places with the fire emergency light to engineering design personnel in the design of similar occasions when emergency lighting to provide the necessary product standard basis.


5, the lowest of fire emergency lamps and lanterns emergency work time increased from 30 min before the standard to 45 min, and increase the step nominal working hours, minimum working time up to 45 min, is considering our country more and more high-rise buildings, 30 min emergency room to work time is not enough;Also consider the product is in use process, as a result of electrical aging emergency work time gradually decline, increased to 45 min to room;Increasing FenDang different nominal emergency work time, is to facilitate the design specification in the future.Obviously, similar to the hospital, high-rise buildings, 45 min evacuation time is not convenient to evacuate occasions may not enough, so can in the design for 90 min or longer time to emergency work, in order to meet the actual needs.


6, about various status indicators, and the new "standard" in the original: "waiting mode" to "main electrical state", its reason is "waiting for status" is easy to produce some misunderstanding, in reality, such as emergency light even though not entirely adequate electricity, also can be said is in "incomplete state of waiting," main electrical interruption or emergency, emergency work just a do not meet the standard requirement of time;And use: "wait state", and the practical significance of the charging indicator is similar, actually.Therefore, the new standard will be revised to "main power status".
"Main power status" would be a green at the same time, the charging status "a red, fault status as yellow, is considered with other fire fighting equipment with relevant standards and criteria and reference the world.The new "standard" has clearly points out the connotation of the "state failure".


7, about the abnormal state of circuit protection clause, is a reference about the similar international standards and combining the actual situation and develop.Abnormal state of circuit protection is refers to the abnormal operating conditions, such as light source, or excessive use light aging failure and so on, in the main power and emergency situations, may be damaged or unsafe factors.


8, about the fluorescent emergency light in the state of emergency access emergency circuit, the starter shall not be given access to the starter emergency conversion time of unreliability, start or result in failure.
Note: consumers owner, in the new project, purchase new gb emergency lights, lights, be sure to get one-on-one inspection report, be sure to buy normal manufacturer of formal product, in case of fire fighting cannot pass inspection.
