Intrusion and hold-up alarm systems (I&HAS) are an established part of the protective security measures commonly deployed at most commercial, and many domestic, premises against the possibility of theft, robbery, malicious damage and arson. For simplicity the term I&HAS is used throughout this document, although it is possible for an intruder alarm system (IAS) or hold-up alarm system (HAS) to exist independently of each other, as well as in combination.
