A new British Standard is in development for audio systems for emergency communication where a sound system is used for emergency purposes where a communication plan is required:
a) under the Terrorism (Protection of Premises) Act 2025, including lockdown, evacuation and invacuation; &
b) also covering audio communication for fire emergencies where the audio system is not connected to the fire alarm, especially relevant post Grenfell for high rise residential buildings.
This is a newly proposed British Standard, the end date for comment with the BSi is 19th Feb 2026.
All comments should go directly to BSi using the BSi Standards Development Portal.
