The emergency lighting centralized power supply has the advantages of safe voltage power supply, low accident risk, low maintenance cost, etc.

The emergency lighting centralized power supply is to merge all emergency lighting control emergency start power sources into one system, so that it can be started in time. There are many power supply methods for emergency lighting, including grid independent power supply, diesel generator set power supply, and battery power supply. Generally used for emergency events, for example, it can be linked with a fire alarm in the event of a fire, and it can be used as emergency lighting when the power is out of accident. There are three emergency lighting control methods, namely, emergency lighting fixtures are turned on 24 hours a day, emergency lighting fixtures are all powered by their own batteries, and emergency lighting fixtures can be used simultaneously with other lamps. The advantages of centralized power supply for emergency lighting: 1. Safe voltage power supply-The fire emergency lighting uses DC24V power supply. The DC24V power supply system is called "uncharged system". Compared with the traditional emergency lighting lamps using 220V power supply, the safety is greatly improved. 2. Low accident risk and low maintenance cost-the battery central station type power supply system has the risk of complete power failure. The battery maintenance and replacement of the self-powered fire emergency lighting is inconvenient, and the operating cost is high. The advantages of decentralized centralized power supply are very obvious . 3. Realized the transition from "nearest evacuation" to "safe evacuation"-it can be linked with fire alarm to quickly and accurately obtain the location information of the fire point. At the same time, the computer automatically generates the evacuation plan and controls the fire emergency signs The lights indicate the best evacuation route.

Emergency lighting centralized power supply suitable for installation places

In actual construction projects, the choice of emergency lighting centralized power supply should be based on the number of floors, scale, complexity of the building, the number of people staying and moving in the building, the characteristics of the production and use of the building, the degree of fire hazard, and the building’s The importance and other factors, as well as other emergency power supply settings, etc., select the appropriate emergency lighting centralized power supply. The combined power supply mode has the advantages of more than two power supply modes, and the shortcomings of one side can be complementary. Although the investment is large, due to its high reliability, it is still widely used in high-rise buildings and some particularly important large buildings. When the normal lighting power supply fails, an emergency lighting part is set to ensure the continuation of normal activities. Generally, backup lighting should be provided in the following areas: 1. After power failure, failure to operate or dispose of places that may cause explosions, fires, and poisoning accidents, such as hydrogen production, paint making, chemical industry, petroleum, plastics, celluloid and its products production, explosive production, solvent production, etc. 2. Failure to operate or handle in time after a power failure will cause confusion in the production process or damage to the valuable parts processed. Such as some processes in the chemical, petroleum and other industries, steelmaking furnaces, metal melting and casting, heat treatment, precision processing workshops in metallurgy and aerospace industries. 3. Turning off the lights will cause major political impact or severe economic losses. Such as important communication centers, radio stations, television stations, power plants and central substations, control centers, *and international conference centers, important hotels, international terminals, transportation hubs, and important power stations (heating, gas, and oil) ), water supply facilities, etc. 4. Turning off the light will hinder the fire rescue work. Such as fire control room, emergency generator room, broadcasting machine room, power distribution room, etc. 5. Important underground buildings will be unable to work and move due to interruption of lighting. Such as subway stations, underground hospitals, large and medium-sized underground shopping malls, underground hotels, underground restaurants, underground garages and underground entertainment venues. 6. When the lights are off, cash and valuables will be stolen. Such as the valuables sales area, cash register and bank cash register of large and medium-sized shopping malls.

The characteristics of the intelligent evacuation indicator

1. When a fire occurs, the system can change the direction according to the location of the fire point, and guide the masses to evacuate away from the fire point. ①When the fire point is close to the exit of the corridor, the evacuation exits on the floors above the exit must be displayed closed, so that the crowd can avoid danger and evacuate to the exit near the fire point on the fire floor. ② People on floors below the fire point can be evacuated to any exit to achieve the purpose of evacuation as soon as possible. 2. The fire scene is full of smoke, and the traditional evacuation indicator will be unclear at this time; this intelligent system can use voice, strobe and other function prompts when approaching or reaching the exit to warn the evacuees, avoid missing the exit, and ensure rapid evacuation. 3. The intelligent system can perform self-inspection and patrol inspection of various indicator lights and emergency lighting fixtures online in real time at ordinary times. Alarm, display, and record the information (lamp number, communication address, fault status) of the malfunctioning lamp.

Application range of emergency lighting centralized power supply

In actual construction projects, the choice of emergency lighting centralized power supply should be based on the number of floors of the building, the size and complexity of the building, the number of people staying and moving in the building, the characteristics of production and use in the building, the degree of disaster risk, and the importance of the building. The level of emergency lighting and the settings of other emergency power sources, etc., are comprehensively considered and compared with technical and economic analysis, and the emergency lighting centralized power source is selected.

The role and advantages of fire emergency lighting

Fire emergency lighting is commonly known as the fire emergency lighting system mainly includes emergency lighting, emergency exit signs and indicator lights. These lightings are set up to guide the trapped people to evacuate or carry out fire rescue operations after cutting off the normal lighting power supply in the event of a fire. However, during daily inspections, it was found that the unit was using fire emergency lights. However, during the daily inspection, it was found that there were many problems in the selection, installation, and use of fire emergency lights. Correctly choosing the power supply control mode and wiring mode of the emergency lighting system, and doing routine maintenance work, will directly affect the function of the fire emergency lighting system.
