While recognizing the value of effective alarm systems in deterring crime and preventing fire losses and while encouraging the use of such alarm systems, it is the purpose of this chapter to require minimum standards for alarm systems and services therefor and to license users thereof to improve system effectiveness and to minimize, insofar as possible, the unnecessary and/or prolonged involvement of emergency public service resources and personnel in or at nonemergency calls.
