The invention relates to the technical field of electronic 
engineering, in particular to a light and 
sound system with a fire-fighting early warning function, and the specific operation steps of a central 
control system are as follows: the central 
control system comprises a security early warning module, a sound control module, a 
light control module and an electric auxiliary module; light and sound in the entertainment venue are turned on before use through the 
light control module and the sound control module, and then whether the light and the sound can work normally or not is tested, so that when a fire occurs in the entertainment venue or a stage, a fire sensor can conveniently sense the fire, a 
signal is transmitted to the central 
control system, the central control 
system controls the alarm to give an alarm, then the central control 
system controls the player, the player is beneficial to 
broadcasting a correct evacuation scheme and 
route, and meanwhile, the central control 
system controls a water spraying system to start, so that the fire scene is extinguished in time, and major disastrous events are prevented.
