Installation precautions and daily maintenance of fire emergency lights

Fire emergency light is the most common lighting tool in fire emergency. It has the characteristics of long emergency time, high brightness, low power consumption and long service life, and is widely used in factories, hotels, schools, units and other public places. Below, I mainly introduce the installation precautions and daily maintenance of fire emergency lights for everyone.

I. Precautions for installation

1. Accurately grasp the characteristics of various wiring modes and avoid blind wiring.

2. If emergency lighting is used as a part of normal lighting, three-wire controllable connection method should be adopted.

3. For multi-storey public buildings, if there is no fire control center, the emergency lighting lamps in various parts can be controlled by local switches (single-lamp single control or multi-lamp control) or three-wire connection with centralized control in the distribution box.

4. For the project with fire control center, in order to meet the requirement that the fire control center can turn on fire emergency lighting in the fire floor and related floors when a fire occurs.

5. in order to ensure the reliability of power supply for fire emergency lighting, diesel generator set should be used as emergency power supply when conditions permit, as long as the generator is put into use, it will have electricity to continue to ensure power supply.

6. Local high illumination is more effective than uniform illumination brought by high installation. Therefore, low-level installation should be advocated, that is, evacuation emergency lighting should be provided near the ground or at the ground height.

7. Do a good job in fire protection of distribution lines, and lay them in the non-combustible structure when concealed, and the thickness of the protective layer is not less than 3mm；; Wear a metal pipe when exposed, and brush a fire retardant coating on the outside of the steel pipe or adopt other fire prevention measures; The line adopts fire-proof cable or fire-resistant cable and wire.

second, the daily maintenance requirements

1. In engineering design, in order to facilitate the usual maintenance and management, it is best to supply power for fire emergency lighting with a dedicated feed circuit layer by layer.

2. All emergency lights are discharged from the factory, and they must be charged for 2 hours before use.

3. The performance of emergency lamps in use should be checked regularly, and the continuous switch test should be passed every half month or one month to check the circuit conversion and emergency function of the battery, and discharge it to prolong the service life of the battery.

note that fire emergency lights, as emergency lighting tools, must be maintained from time to time and inspected regularly to avoid unnecessary troubles when disasters occur.
