The code of practice now refers to all activations as alarm activations within the standard. All monitoring centres for lone worker services will need to be an ARC conforming to BS 9518 and a conforming ARC standard, e.g. BS 5979, BS EN 50518. In addition, the standard sets target response times for all lone worker alarm activations. This Technical Bulletin (0063) outlines the changes within BS 8484:2022. Implementation timescale for Approved Companies BS 8484:2022 was published on 31st March 2022 and will be implemented into NSI current schemes from 31st March 2023. During this period, any non-conformance found will be raised as an “Auditor Note.” Any non-conformance found after the transition period will be raised as a formal non-conformance report(s) (“Improvement Observation or Improvement Need”) being raised.
