In the engineering design, in order to facilitate daily maintenance and management, fire emergency lighting is best to be supplied with a dedicated feeder loop for each floor.

In order to ensure the reliability of the fire emergency lighting power supply, the low-voltage emergency bus section of the substation should be used to supply power.When the diesel generator set is used as the emergency power supply, as long as the generator is put into use, it has electricity to continue to ensure power supply.

In a fire situation, there is less smoke and more oxygen close to the ground, and the instinctive response of people to evacuate is to bend over or crawl forward. Therefore, local high-illuminance lighting is more effective than the uniform illuminance brought by high-level installation.

It is recommended to install it in a low position, and provide emergency lighting for evacuation close to the ground or at the height of the ground.

In addition,the exploision proof emergency lighting is delivered in a discharged state and must be charged for 20 hours before being discharged.
