New British Standard proposed for emergency audio communications

The proposal relates to a new British Code of Practice covering the use of sound systems for emergency purposes in premises where a formal communication plan is required. Further details on the proposal can be found on the BSI’s Standards Development Portal.

Scope of the proposed British Standard

The proposed Code of Practice would provide guidance on emergency sound systems used under the Terrorism (Protection of Premises) Act 2025 (ie Martyn’s Law), including communication for lockdown, evacuation and invacuation scenarios and also for fire emergencies, particularly so in high-rise residential buildings where audio communication systems operate independently of the fire detection and alarm system.

This is considered particularly relevant in the context of post-Grenfell Tower fire safety, where the ability to deliver clear and evolving instructions to residents during an incident is essential.

Purpose and focus

The BSI is considering the development of this new British Standard in order to address areas where existing guidance is currently limited or otherwise fragmented. The proposed Code of Practice would focus on communication outcomes, providing guidance on planning and system design, audibility and intelligibility and also testing and the ongoing operation of emergency audio systems.

The British Standard is intended to complement existing fire, security and product standards rather than duplicate them.

FIA member comment

The FIA is drawing this proposal to the attention of its members and invites members to consider the scope and potential impact of the proposed British Standard.

The BSI is currently seeking feedback on the need for the British Standard, its scope and its potential value to duty holders, designers, operators, residents and enforcing authorities alike.

The proposal is open for comment until 19 February. FIA members who wish to contribute their views are encouraged to submit their comments directly to the BSI via the project link (registration may be required).
