What Is The Difference Between Emergency Lighting And Evacuation Lighting?

The fire emergency lighting and evacuation indicator light have the same function for emergency, and they need to be able to supply power to the emergency bulb when the normal power supply disappears. But the functions are different. Emergency lighting shall be installed in stairs, passageways, gates and other places with evacuation lighting; The emergency lights provided by the emergency lighting manufacturer are used to indicate the position and direction required for evacuation, such as "safe passage", "forward", etc.

1. Fire emergency lighting and evacuation indicator light need to be equipped with two kinds of power supply, namely normal power supply and emergency standby power supply. The emergency standby power supply is generally supplied by the self-contained power supply and the storage battery. If the battery is used, the continuous power supply time shall not be less than 200 minutes.

2. The illuminance of fire emergency lighting and evacuation indicator light shall not be less than 0.5lx to fully illuminate the sidewalk, stairs and other evacuation routes. The fire control room, fire pump room, self-contained generator room and the parts that still need to work in case of fire also need to ensure normal lighting.

3. The safety evacuation sign shall be set at the top of the fire fighting passage or evacuation passage and at the corner 1 m below the ground. The distance between the signs on the footbridge shall not be greater than 20m. Fire emergency lighting and safety evacuation indicator lights shall be equipped with protective covers made of glass and other non combustible materials.

4. The evacuation staircase shall have obvious signs indicating the location and number of floors, so that the personnel in the building can know the location in time for safe evacuation.

Before installing the fire emergency light, the fire emergency light shall be simply checked to test whether the emergency function of the fire emergency light is normal. The test method is very simple. The new national standard fire emergency light produced now generally has a test button on the front of the fire emergency light panel. After the fire emergency light is powered on, users only need to press the test button with their fingers, and the two fire emergency light sockets will light up at the same time.
