1. Purchase standard fire emergency lights should pay attention to the products of regular manufacturers. In order to save costs, some manufacturers produce more unqualified products. The loss should be. When you purchase, pick it up and shake it twice. Check the internal battery and power transformer to determine if the components are stable. If there is sound inside, it means the internal components are loose. If there is no sound, it means that the components are well fixed.

2. Check if the function switch is ok. Place the switch in the dual fluorescent lamp position. At this time, the two lamps should be lit at the same time, and the brightness is the same without flicker. Stick the ear on the lamp housing and listen carefully to the internal step-up transformer for leakage. If there is a leakage problem, the step-up transformer will form a “sweet” sound.

3, connect the power supply, the charging indicator should be lit, listen to the internal power transformer is not because of the loose core caused by the "beep" sound. Fourth, the use of fire emergency lights should pay attention to, the lights are dim, fluorescent lights should be charged first when charging is difficult, a charge takes about 14 hours. When not in use for a long time, it should be charged once every 3 months for about 8 hours.
