Fire detection and fire alarm systems for buildings.Part 8:Code of practice for the design, installation, commissioning and maintenance of voice alarm systems
This standard gives recommendations for the design,installation,commissioning and maintenance of voice alarm systems which automatically broadcast speech or warning tones, in response to signals from their associated fire detection and fire alarm systems.It also covers systems that include a manual facility for the transmission of live voice messages as well as automatically generated messages for emergency purposes.
NOTE 1 The fire detection and fire alarm systems themselves are covered by BS 5839-1.
Systems that depend solely upon manual intervention are not covered by this standard. However, this standard can be used for guidance in the design, installation, commissioning and maintenance of such systems.
NOTE 2 This standard applies to extensions and alterations to existing systems, at least in respect of the design, installation, commissioning, maintenance, and the certification of the new work, albeit that the extended or altered system might not, overall, conform to this standard. NOTE 3 BS 7827 provides further recommendations in respect of sports venues.
