Abstract: This article from the perspective of fire monitoring the current fire emergency lighting problems in the applications, analyzes the causes of these problems, while ignoring for the supervision and management process, the problem of dealing with countermeasures and methods.





HC Fire Network 1. Introduction Fire emergency lighting mainly refers to the emergency lighting, emergency exit signs and lights, is Fire Occurs leading to the normal lighting for some reason out of the non-normal circumstances, for the time being to continue to work to guide trapped evacuation or fire fighting and rescue operations set to start lighting, fire protection facilities is an important part. With the rapid development of high-rise civil construction, high-rise buildings and special features integrated multi-storey building rapid increase in fire emergency lighting applications are more and more widely. Fire Emergency Lighting Research and investigate the status and needs of fire accidents in the state for the protection of personal safety, to maintain the necessary action to carry out fire fighting and rescue combat losses to reduce incidents of great practical significance.

2. Problems Fire supervision and management process, we often find fire emergency lighting in the design, installation and use and so there are many practical problems, the key point is often not achieve its proper role. Such as setting the location and number do not meet specifications; installation forms and selection of inappropriate; power supply and control means unreasonable; product quality reach the national standard; to maintain properly, serious damage and so on. Many of these problems easily overlooked fire monitors, causing system deficiencies, directly affects the use of the system and should play a role, even a fire hazard.





These problems are mainly as follows: 1) System Selection unreasonable, reduced product life; 2) Control error, man-made additional control switch, leading to system failure; 3) transmission and distribution lines and Lighting Protection level is low; 4) set the location of inappropriate and inadequate illumination. The following combination of my work, I talk about the views on these issues and experiences.





3. Cause of the problems Fire emergency lighting in applications there are many problems, from the laws and regulations, supervision, design, construction, operation and maintenance of point of view, the main cause of the problem in four areas:





3.1 Related laws and regulations are not perfect.


China's current laws and regulations of the lack of adequate emergency lighting fire binding, design, construction and "no outline to be investigated," supervision "no basis." Although China promulgated and implemented in 2000, a new industry standard "fire emergency lighting." The standard requirements of the product has reached the advanced level of European and American countries, but the state of its design, selection, installation, commissioning and use no corresponding professional specifications. Only in the "architectural design code for fire protection" (hereinafter referred to as "Building Regulations"), "Building Energy Standards" (hereinafter referred to as "high regulation") and the main specification of the universal set of emergency lighting were simple conceptual Review. In the main specification of emergency lighting design, installation, and acceptance that there is no detailed description of the relevant Technology Requirements have not been strengthened. At the same time the norms have been rigorous, and have a different, prone to misunderstanding and confusion. Such as "civil Electric Design Code "(hereinafter referred to as" public regulation ") Section 24.7.6 provides that" signs on the corridor should not be greater than 15 meters distance light "and" Building Regulations "Article 10.2.9 provides that" aisle space on the signs not more than 20 meters ";" people rules "section in Appendix C.3.12 Article 24.7.7 provides that" back-lighting intensity of not less than 10% of normal illumination, the minimum is not less than 5LX ", and" high regulation "section 9.2.2 Article "required to work the room of fire emergency lighting, should guarantee the normal lighting of the illumination," "civil Lighting Design Standards," Article 4.1.3 states that "emergency lighting illumination, in the workplace should not be less than the place 5% of the general lighting illumination. " Legal norms related to inadequate, inconsistent, resulting in a fire emergency lighting in the absence of specific applications and maneuverability, can not fully guarantee its effectiveness and role.





3.2 fire monitoring mechanisms are inadequate.





Fire monitoring mechanism can not effectively improve the emergency lighting problems, there are two main reasons.
