Emergency lighting, like fire extinguishers and smoke detectors, is an essential part of commercial, industrial and public buildings that can serve people in buildings in emergencies. National, state, and local regulations provide guidance for the practical application of emergency lighting. To understand the regulations, you must first understand the National Electrical Code (NFPA 70) and the Life Safety Regulations (NFPA 101). It is important to note that the regulations only reflect the minimum standard requirements.
î—¥
The regulations require that an emergency light source be illuminated for at least 90 minutes (eg, fluorescent emergency ballasts or lighting fixtures using generators). Local or state building codes can impose additional requirements on lighting in certain situations;
î—¥
The emergency light source must start working within 10 seconds of the normal power disconnection. This applies to the case where the illumination is switched from one source (eg a conventional source) to another source (eg a battery-powered fluorescent emergency ballast or a source system using a generator);
î—¥
Regulatory requirements clearly indicate changes in the direction of the safe passage;
î—¥
National regulatory requirements (as currently explained) Emergency lighting should be capable of producing an average initial illumination of at least 1 foot of candlelight on the ground of a safe passage (start of 90 min working hours). The minimum and average of the channel ground illumination is 011 foot candles. This value can vary in some areas depending on local or state regulations. A safe passage is a path that guides people in a building through a building to a safe location. Most people think that the safety passages are inside the building. In fact, the safe passage may include an area outside the building that leads to a public road (such as a street). A passage that extends beyond the building is called an outdoor passage. In recent years, outdoor access has become a more important area in regulations and emergency lighting programs.

Testing is another important requirement of regulations. The emergency light source must be tested every 30 days for 30s. For battery-powered devices, 90 minutes of testing must be performed annually. Emergency lighting devices must have continuous detection capabilities and must maintain a written record of the test results. 1 Detection and maintenance Since the emergency lighting device is only used in an emergency, it is important to ensure that the device functions normally at any time. Irregular, basic, frequent testing and subsequent maintenance are important to care for the occupants. Peace is the most important, but responsibility is still a problem, especially when there is a liability issue, and proper testing and maintenance can provide evidence. In addition, the emergency light source is an important investment, and maintenance should be guaranteed; various regulations stipulate that inspection and maintenance must be carried out. Despite regulatory requirements and common sense, not all emergency sources are regularly tested and maintained. When it fails, it usually involves two factors, time and cost; but when the detection is easy, you can reduce these two concerns. Emergency lighting is usually composed of multiple ways. The most common emergency lighting power supply is the Fluorescent Emergency Ballast (FEB).
FEB has the following advantages:
î—¥
Provides reliable lighting and works independently of other emergency lighting fixtures. If one FEB fails, the failure has no effect on other FEBs. However, if a generator system fails, the fault can easily have a significant impact on the life safety system;
î—¥
Complement architectural and lighting design. But it does not affect its aesthetic effects; emergency lighting can only be seen when needed;
î—¥
Producing the same light as a normal light source;
î—¥
Save installation time and costs;
î—¥
Because the FEB is hidden inside or near the luminaire, it does not become the target of vandals. 2 There are many types of emergency ballasts sold on the market for intelligent ballasts. From products that only meet regulatory requirements to smart high-end products, smart high-end products can make the lives of building owners and users. More convenient. Intelligent ballasts are very different in detection and maintenance from ordinary ballasts.
