Marking table for NCP 120 & PD 6662:2017 applying European & British standards for intruder and hold-up alarm systems (I&HAS) for preventative maintenance NSF 272 – Issue 1 September 2024 NSI applies this marking table to NACOSS Gold and Systems Silver-approved companies when inspecting Intruder and Hold-Up Alarm Systems (I&HAS) being maintained to standards called up by PD 6662:2017. De-merit marks (points) are given in relation to NCP120, BS 9263:2016, PD 6662:2017, the BS EN 50131 series, DD CLC/TS 50131-7:2010, BS 8243 and BS 8473 Notes may also be raised on NSI Inspection Reports in relation to PD 6662: 2017, and/or the standards called up by PD 6662, for which no specific reference has been made in this marking table. We draw your attention to NSI Code of Practice NCP120 Supplementary Code of Practice for the Planning, Installation, Commissioning and Maintenance of Intruder Alarms.

NSF 272 Issue no. 1 Issue date September 2024 Page 2 of 5 Document owner Director of Technical Services and Field Operations Document classification PUBLIC (RESTRICTED) © NSI 2024 Marking table for PD 6662:2017 / BS 8243:2021 / NCP 120 intruder and hold-up alarm system preventative maintenance This marking table is divided into Sections A to E as listed below. Item Title A Maintenance record & agreement B Testing & detection (inc. tamper) C Equipment positioning & visual inspection D Control and Indicating equipment Including power supplies E Setting and unsetting Notes 1. Each section of this marking table contains one or more deviations (see pages 3 to 5). 2. Each deviation is given a clause reference (e.g. BS EN 50131-1/17: 4), a code (e.g. B1A) and a point (e.g. 2 points). 3. NSI inspection reports detail deviations by clause, code, description, and points. Example: BS EN 50131-1/17:4 B1A I&HAS does not have mandatory functions for detection, triggering, processing, notification, or means to operate. 2 points. 4. Points are awarded for each individual deviation except that the maximum number of points awarded in relation to Section A (Documentation) is 1 point. 5. The total number of points awarded results in a grading (A to E). A = 0 points, B = 1-2 points, C = 3-5 points, D = 6-8 points and E = 9 points or more. The I&HAS will normally require a re-inspection if Grade D or E is achieved.
