9.18.020 - Definitions.

A. "Alarm Agent" means a person employed by an alarm company operator, whose duties include selling on premises, altering, installing, maintaining, moving, reporting, replacing, servicing, responding or monitoring an alarm system, or a person who manages or supervises the duties described. "Alarm Company Operator" means a person who engages in business or accepts employment to install, maintain, alter, sell on premises, monitor, or service alarm systems (except for an alarm agent). "Alarm Company Operator", however, does not include a business, which merely sells on premises, monitors, or responds to alarm systems at the protected premises.

B. "Alarm Systems" means equipment which is intended to notify persons of an emergency requiring urgent attention and to which police are expected to respond. The term "Alarm System" includes equipment, which is designed to (1) detect an emergency or (2) to be activated by a person to report an emergency.

C. "Alarm User" means (1) a person who owns or is entitled to possession of any premises on which an alarm system has been installed; or (2) a person subscribing or contracting with an alarm business for the leasing, servicing or monitoring of an alarm system. In the case of corporate or other users, which are not natural persons, the natural person who has a managerial responsibility for the premises where the alarm is located shall be deemed the "Alarm User".

D. "Audible Alarm" means an alarm system which, when activated, generates a sound which is audible outside the structure where the system is located.

E. "Central Station Alarm System" means an alarm system which, when activated, generates a signal or transmission to a station outside the structure where the alarm was generated (which station then notifies a communication center, i.e., Contra Costa County Sheriff Dispatch Center.

F. "Emergency" means a situation, which poses an immediate threat to persons or property. An "Emergency" includes an unlawful entry onto premises or an attempted unlawful entry, the commission of a crime, the existence of a fire, or the occurrence of a serious medical problem.

G. "False Alarm" means an activated alarm or alarm signal from any alarm, which is responded to by the police department but for which no emergency situation exists or where there is no evidence to indicate that there was an emergency situation as determined by the responding officer. False alarms are subject to a service assessment fee if, after written notice from the police department that the system has generated a false alarm, the system then generates an additional three (3) or more false alarms within any thirty-day period. Nay number of false alarms within a twenty-four-hour period, however, are deemed one false alarm under this section. An alarm initiated by: (1) a severe storm or earthquake or other violent act of nature; or (b) the interruption of telephone service between premises ("Trouble Status Alarm") does not constitute a false alarm for purposes of this chapter.

H. "One Year" means a period of twelve (12) consecutive months.
