Fire emergency lighting is one of the most common fire products, modern buildings generally need to install fire emergency lighting, and business places must be installed with fire emergency lighting. So why install fire emergency lights? What does a fire emergency light do? Let me introduce it to you.
The main function of fire emergency lights is to provide lighting for the fire scene in case of power failure. When there is a fire, the power supply system at the scene of the fire will be cut off.

The fire emergency lights are equipped with their own spare batteries. When the power is cut off, the fire emergency lights will automatically switch to the standby battery state and continue to provide lighting. Each emergency light needs to be kept lit for 1.5 hours after power is cut, according to the national Fire design code.
The explosion-proof lamp should be checked from the nameplate and the product manual before installation: explosion-proof type, category, grade and group; The protection grade of the shell; Installation method and fastener requirements for installation, etc. The installation of explosion-proof lamps should ensure that the fastening bolts should not be arbitrarily replaced, spring washer should be complete. Dustproof, waterproof sealing ring should be placed as is when installing. At the cable inlet, the cable and seal gasket should be closely matched, the cable section should be round, and there should be no concave and convex defects on the sheath surface. The excess inlet shall be sealed according to the explosion-proof type, and the compression nut shall be tightened to seal the inlet. Explosion-proof lamps often see ip65, IP55 and so on.
