Publication of NSI Code of Practice for Intruder Alarms NCP 120 (Replacing NACP 11)

A review of NACP 11 (NSI NACOSS Gold Supplementary Code of Practice for the Planning, Installation and Maintenance of Intruder Alarms) concluded significant change was required to address today’s customer needs and a changing security environment. Post-revision it was deemed necessary to create a new NSI Code of Practice 120 Issue 1 for the Planning, Installation, Commissioning and Maintenance of Intruder Alarms and to withdraw NACP 11.

NCP 120 introduces the following main requirements:

  • Documented process for handover to another approved company where maintenance is to be transferred.
  • Compliance with NPCC or Police Scotland security system requirements.
  • Specific requirements from BS 7671 (wiring regulations).
  • Clarification of requirements found in BS 9263 for on-site maintenance visits.
  • Any components replaced during a corrective maintenance visit should be functionally tested.

Implementation Dates:

Existing companies approved to NACOSS Gold and Systems Silver will need to be compliant by 1st April 2022. New NSI applicants to NACOSS Gold and Systems Silver will need to comply with NCP 120 Issue 1 with immediate effect.

NSI will begin auditing to this new Code of Practice from 1st December 2021, allowing companies the necessary time to review and adapt their processes and procedures to meet its new requirements. From 1st December 2021 until 1st April 2022 a non-compliance will have an audit note recorded against clauses of the Code. From 1st April 2022, normal audit practice will resume where findings will be recorded against clauses of the Standard and will have to be satisfactorily addressed before approval can be granted.

How do I obtain a copy of NCP 120?

NCP 120 Issue 1 is available as a download via the NSI Approved Company Area by navigating to either NACOSS Gold or Systems Silver then to Codes of Practice, referencing Technical Bulletin 0062.
