Emergency lighting is widely installed in the corridors and fire safety doors of public places and is a professional equipment for fire safety. Many emergency lights on the market are manufactured by the fire safety department of the fire safety department. This department has various functions, but most of them are for reducing risks. When the emergency light is cut off, it will automatically turn on and off when there is an incoming power. It is used as a backup lighting device. The battery is equipped with a battery, providing power when the power is off and charging the battery when the power is on. So, what height should emergency lighting be installed at?
1. The battery charging fails because rechargeable batteries are often in a shallow positive charge and shallow charge state, with insufficient battery power or failure, and need to replace the battery. When the battery charging power circuit Q2 charges the battery, the current is quite large and is prone to being damaged.
2. If there is no AC power supply, the main power indicator light d14 does not light up. A common fault is the long-term connection of the transformer.
What are the requirements for the position of emergency lighting?
1. It and the safety evacuation indicator lights need two power sources: normal power and emergency backup power. The emergency backup power is usually self-powered and battery-powered. When using the battery, the continuous power supply time should not be less than 200 minutes.
2. Emergency lighting and safety lights' indicator lights should be at least 0.5 lx to fully illuminate the sidewalks, stairs and other evacuation routes. Fire control rooms, fire pump rooms, independent power plants and components still needed to be kept in the fire should provide general lighting.
3. Safety evacuation signs should be located at the top of the emergency exit or at the corner of the escape passage wall and 1m below, and the distance between the signs should not exceed 20m. Emergency lighting and safety evacuation lights should be equipped with protective covers made of glass and other non-combustible materials.
4. Fire escape emergency lights should be located on the walls or ceilings. Emergency lighting is located on both sides of the fire passage or exit, 2.2m from the stairs or the top of the stairs. Long evacuation routes should follow the fire. According to department instructions or the actual usage site of emergency lighting intensity, increase the density of lamps and install them reasonably.
5. The installation distance of emergency evacuation indicators or emergency exit indicators should not exceed 20m. The installation specifications, installation height and lamp density of fire exit indicators should comply with the actual installation environment and the actual installation and use of emergency lights.
These are the heights at which emergency lighting should be installed. It is an important safety facility for modern public buildings and industrial buildings, closely related to personal safety and building safety. When a building has a fire or other disasters and the power is interrupted, it plays an important role in personnel evacuation, fire rescue work, the continued operation of important production and work, or necessary operation and disposal.
