This British Standard gives recommendations for the design, installation and configuration of intruder and hold\u2011up alarm systems (I&HAS) that incorporate alarm confirmation technology, where such I&HAS have signalling systems that signal to an alarm receiving centre (ARC) and require a police response.<\/p>\n

It includes recommendations intended to minimize the likelihood of false alarms.<\/p>\n

\n

NOTE 1 Hold-up alarm system (HAS) alarm confirmation can be used as required in the NPCC and ACPOS\/PS security systems policies [1] [2].<\/p>\n<\/blockquote>\n

\n

NOTE 2 Confirmation of a hold-up alarm (HUA) might be required to regain police response only where the URN (unique reference number) has been withdrawn following false alarms. See the NPCC and ACPOS\/PS policies [1] [2].<\/p>\n<\/blockquote>\n
