What are the specification requirements for emergency lighting installation?
Fire emergency lights advocate low installation, that is, near the ground or at the height of the ground. Because in the state of fire, there is less smoke and more oxygen near the ground, people usually bend over or crawl to escape, and local high illumination is more effective than high-level installation of uniform illumination.
In addition to the normal power supply, the power supply of the emergency lighting is supplied by another power supply, or it is supplied by a diesel generator set independent of the normal power supply, or it is powered by the battery cabinet or the emergency lamp with its own power supply is selected.
The lighting of the evacuation should not be more than 15 seconds, shopping malls and other densely populated places should not be more than 5 seconds, safety lights should not be more than 0.5 seconds, and the duration of emergency lights should not be less than 30 minutes. The working time of the fire-related room should not be less than 2 hours.

Emergency lights belong to safety lighting, such as shopping malls, hotels and office buildings. When there is a power outage at night, the emergency lights will be activated, and can also be used for emergency evacuation and escape. Under normal circumstances, emergency lighting is powered by municipal power, and when there is no municipal power, it is switched to battery power.
6. The installation standards of emergency lights are as follows: in modern engineering design, fire emergency lights had better be supplied by a special feed circuit according to the layer, which is to facilitate the maintenance and management.
What is the installation standard of emergency lights
1. Fire emergency lights can be installed on the aisle by 20 meters each. The power supply for fire emergency lights and safety evacuation exit lights should be installed independently and should not be linked to electric lights or electrical appliances for future management.
2. the common double-headed fire emergency lights, which are commonly used in the installation code of fire emergency lights, are generally installed above the door frame of the exit of the evacuation passageway, on the walls of corridors and safety exits, at a height of more than 2 meters from the ground; in large-scale electronic markets, shopping centers and other places, double-headed emergency lights are directly mounted on the posts.
3, emergency lighting installation specification requirements: the emergency lighting power supply in addition to the normal power supply, another power supply, or independent of the normal power supply diesel generator set power supply; or by the battery cabinet power supply or choose its own power supply emergency lamps.
4. the emergency lights for fire evacuation should be located on the wall or on the ceiling (suitable for fire emergency lights, fire emergency ceiling lights, fire emergency downlights / spotlights, etc.).
5. Emergency lighting system power supply control mode the emergency lighting system used in China is mainly self-contained power supply independent control type, the normal power supply is connected to the ordinary lighting power supply circuit, usually the emergency lamp battery is charged, when the normal power supply is cut off, the standby power supply (battery) automatically supplies power.
Some requirements of the installation specification for various types of emergency lights
1. Fire emergency lights advocate low installation, that is, near the ground or at the height of the ground. Because in the state of fire, there is less smoke and more oxygen near the ground, people usually bend over or crawl to escape, and local high illumination is more effective than high-level installation of uniform illumination.
2. The common double-headed fire emergency lights are generally installed above the door frame of the exit of the evacuation passageway, on the walls of corridors and safety exits, at a height of more than 2 meters from the ground; in large-scale electronic markets, shopping centers and other places, double-headed emergency lights are directly mounted on the posts.
3. The setting of evacuation sign lights does not affect normal traffic, and other signs which are easy to be mixed with evacuation lights are not set around it. Emergency lighting fixtures, lamps and lanterns with a temperature higher than 60 ℃ in operation shall take fire prevention measures such as heat insulation and heat dissipation when they are close to combustibles.
