In discussing reasons for law enforcement concern about false alarms, the report addresses costs, the risk of accidents, wear and tear on equipment, reduction of service while alarms are being investigated, and threats to officer safety when numerous false alarms erode caution. Four major types of private security alarm systems are examined: local, direct connection, central station, and telephone dialer. The sensor, control unit, and alarm elements of such systems are explained. The report explores conflicting definitions of false alarms by the police and the alarm industry, as well as differing statistics offers by the two groups. Improper use, poor installation, defective equipment, customer error or negligence, and line trouble are among the causes of false alarms discussed. Local government strategies include ordinances, permit systems, fee systems, and reduction of police services in very specific circumstances. Examples illustrate the benefits and shortcoming of these approaches. Steps for a jurisdiction's plan of action against false alarms are detailed. Tables, footnotes, and nine references.
