Home emergency light introduction
Home emergency light The fire emergency lighting system mainly includes accident emergency lighting, emergency exit signs and indicator lights. It is set up to guide the trapped people to evacuate or launch fire fighting and rescue operations after the normal lighting power supply is cut off in the event of a fire. However, in the daily inspection, it was found that there are many problems in the selection, installation and use of fire emergency lamps. Therefore, reasonable selection of the power supply control method and wiring method of the emergency lighting system, and daily maintenance work will directly affect the function of the fire emergency lighting system. In daily life, it is necessary to check frequently to prevent problems before they occur!
Notes for household emergency lights
1. Accurately grasp the characteristics of various wiring methods to avoid blind wiring.
2. If emergency lighting is used as part of normal lighting, three-wire controllable connection should be used;
3. For multi-storey public buildings, if If there is no fire control center, emergency lighting fixtures in various parts can be controlled by on-site switches (single lamp single control or multi-lamp control) or three-wire connection method with centralized control in the distribution box;
4 . For projects with a fire control center, in order to meet the requirements that the fire control center can turn on the fire emergency lighting on the fire floor and related floors when a fire occurs.
Installation and maintenance of household emergency lights
1. In engineering design, in order to facilitate daily maintenance and management, it is best to use special-purpose lighting for fire emergency lighting by floor. Feed circuit power supply.
2. In order to ensure the reliability of the power supply for fire emergency lighting, the power supply should be supplied by the low-voltage emergency bus section of the substation, that is, 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.
3. In a fire state, there is less smoke and more oxygen near the ground, and the instinctive response of people to evacuate is to bend over or crawl forward, so the local high-intensity lighting is more uniform than the high-level installation. efficient. Therefore, low-level installation should be promoted, that is, emergency lighting for evacuation should be provided close to the ground or at ground level.
4. The emergency lights are all factory-discharged and must be charged for 20 hours before use.
5. 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 the emergency function of the battery, and discharge it to prolong the use of the battery life.
6. Do a good job of fire protection for power distribution lines, lay it in a non-combustion body structure when it is darkly laid, and the thickness of the protective layer is not less than 30mm; wear a metal pipe when it is exposed, and brush fire-resistant paint on the outside of the steel pipe Or adopt other fire protection measures; use fire-resistant cables or fire-resistant cables and wires for lines.
