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.
