Emergency Light Manufacturers : Fire Emergency Lighting Is Strong
Emergency Light Manufacturers notes: fire emergency lighting with strong open refers to the fire emergency lighting lamps are usually controlled by the switch, fire emergency no matter what state the switch is in, can be through strong open line power supply to achieve lighting emergency lighting.
The so-called emergency lighting refers to the lighting for temporarily continuing work, ensuring safety or personnel evacuation when the normal lighting is extinguished for some reason. Article 10.3.2 of “code of electrical design for civil buildings” (JGJ/ t16-2008) divides emergency lighting into standby lighting, evacuation lighting and safety lighting.
And strong fire emergency lighting and is especially after the fire, the fire linkage control signal linkage control force emergency lighting lamps and lanterns, stems from a specification for design of automatic fire alarm system (GB50116-2008) 22.214.171.124 article, “the fire linkage control the working state of emergency lighting system shall ensure that in case a fire occurs in a fire emergency lighting system in all fire emergency lighting lamps and lanterns” requirements.
In actual construction engineering, the emergency lighting power supply should be selected according to the structure of the layer number, size, complexity, how many buildings stay and mobile people, the production and use of building characteristics, fire danger degree and the structure of the important degree, and the other the setting of emergency power supply, etc., comprehensive consideration for technical and economic analysis and comparison, choose the optimal emergency lighting power supply.
The combined power supply mode has the advantages of more than two kinds of power supply, and the disadvantages of one side can be complementary. Despite the large investment, it is still widely used in high-rise buildings and some especially important large-scale buildings due to its high reliability.
Setting place for emergency lighting
Except for single and multi-storey houses, the following parts of civil buildings, workshops and category c warehouses shall be equipped with evacuation emergency lighting fixtures:
1, closed stairwell, smoke prevention stairwell and its front room, fire elevator room or Shared front room and fire protection floor (room);
2. Fire control room, fire pump room, self-provided generator room, power distribution room, smoke prevention and exhaust engine room and other rooms that still need to work normally in case of fire;
3. Audience hall, exhibition hall, multi-function hall and business hall, restaurant and studio with a floor area of over 200 square meters;
4. Public activity places in underground or semi-underground buildings or basements or semi-basements with construction area of more than 100 square meters;
5. Evacuation walkway in public buildings.
