Marking table for PD 6662:2017 applying European standards for intruder and hold-up alarm systems (I&HAS) and applying BS 8243:2021 for I&HAS incorporating alarm confirmation technology NSF 670 Issue 7 August 2021 NSI applies this marking table to NACOSS Gold and Systems Silver approved companies when inspecting Intruder and Hold-Up Alarm Systems (I&HAS) installed to PD 6662:2017 and the standards called-up by PD 6662:2017. NSI applies Section W of this marking table when inspecting security fog devices to BS EN 50131-8. De-merit marks (points) are given in relation to PD 6662:2017, the BS EN 50131 series, DD CLC/TS 50131-7:2010, BS 8243, BS 8473 and BS 4737:Section 3 (various parts). 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 Technical Bulletins 0040 “Guidance on the implementation of PD 6662:2017” and 0059 “ Publication of BS 8243:2021 – Design, installation and configuration of intruder and hold-up alarm systems designed to generate confirmed alarm conditions. Code of Practice”. Note: Requirements relating to confirmation/verification of hold-up alarms only apply when necessary, for example to regain police response under the provisions of the NPCC policy.

Each section of this marking table contains one or more deviations (see pages 4 to 30 below). 2. Each deviation is given a clause reference (e.g. BS EN 50131-1/17: 4), a code (e.g. B1A) and a point (for example, 2 Points). 3. NSI Inspection Reports detail deviations by clause, code, description, 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. Clause Code Deviation Points A.
