The short answer

Test it every week with the fire alarm, checking that the right message is broadcast and can be understood, and have a competent specialist carry out maintenance inspections every six and twelve months, as BS 5839-8:2023 recommends.

Medium confidence: treat these intervals with care

Intervals confirmed only through the professional institute's summary (a copy hosted by a third party) and a consultation draft, not the published BS 5839-8:2023.

Confirm the interval against the current edition of the standard, or with the specialist who maintains the system, before you fix it in a contract or a calendar.

The law

Article 17 of the Regulatory Reform (Fire Safety) Order 2005 requires a voice alarm system that forms part of the fire warning arrangements to be kept under a suitable system of maintenance and in efficient working order. The Order sets no test interval.

The standard

BS 5839-8:2023, the code of practice for voice alarm systems. The previous edition was dated 2013.

Records to keep

  • Voice alarm log book with each weekly test
  • Six-monthly and twelve-monthly maintenance inspection reports
  • Records of faults and repairs

Notes

The intervals are British Standard recommendations, not legal requirements. They are taken from the professional institute's guide to the 2023 standard and from the consultation draft of that standard: the published standard itself was not available to check.

A public address system that is not relied on in an emergency is not a voice alarm system and is outside this entry.
