Application Summary AI generated
This standard specifies the acoustic characteristics required for an audible emergency evacuation signal, including its temporal pattern, frequency range, and sound level. It is applied in public buildings, industrial facilities, and transportation hubs in China to ensure that evacuation alarms are distinct from other sounds and effectively prompt immediate action during emergencies. The standard provides a technical basis for the design, testing, and verification of such signals in fire alarm systems and safety equipment.
