Voice alarm system standard

Voice alarm system standard encompasses the technical and operational requirements for public address systems that deliver emergency messages throughout a building. In commercial real estate—offices, retail spaces, and industrial facilities—this standard ensures alarm announcements are intelligible and audible in all occupied areas, including rooms with high background noise.

Building owners and facility managers must install and maintain compliant systems, with annual professional inspections mandatory. The standard covers speaker placement, audio quality, backup power supply, and clear message protocols to enable swift and safe evacuation during emergencies.
