The chief may declare an alarm system at a specific location to be a nuisance if such alarm system actuates excessive false alarms. The city council finds and determines that four (4) false burglary alarms within one year (365 days) or three (3) false robbery alarms within three hundred sixty five (365) days is excessive and thereby constitutes a public nuisance. The chief shall not consider any false alarm in this computation of nuisance alarms if such false alarm was generated by an earthquake, high intensity wind, unusual act of nature or general power outage. Nuisance alarms shall be considered those that are the result of the negligence of the alarm user, the agents or employees of the alarm user, or a defect in the alarm system. (Ord. 2457 § 1, 2000)
