Alarm systems – Intent of Criterion 2 - KBCN1707

The intent of Criterion 2 is as follows: A documented plan is in place to ensure that when the alarm is triggered, whether due to a fire or security incident, a system fault or a false alarm, building staff and occupants understand what actions to take. This must include any necessary communication with ARC staff, emergency services and other building users. This clarification will be incorporated in the next update of the technical standard.

29 April 2025 - Due to the ambiguity of the guidance in technical manual, where project teams demonstrate that the assessment documentation was prepared prior to the publication of this KBCN, and that the wording of criterion 2 in the technical manual has been followed, this KBCN can be disregarded.
