Editor's note— Ord. No. 21-10, § 2, adopted May 25, 2021, repealed the former ch. 8.32, §§ 8.32.010—8.32.110, and enacted a new ch. 8.32 as set out herein. The former ch. 8.32 pertained to similar subject matter and derived from Ord. 92-03 § 1 (part), adopted 1992.

The city council finds and declares that:

A. The frequency of falsely activated or defective security alarm systems have resulted in a critical drain upon the services and resources of law enforcement personnel; and

B. The regulation of security alarm systems will improve the optimum use of law enforcement personnel in the detection and prevention of crime in the city, rather than in responding to false and erroneous alarms

"Alarm company operator" means and includes any business operated for any consideration whatsoever, engaged in the installation, maintenance, alteration or servicing of alarm systems or which responds to alarm systems. "Alarm company operator" does not include a business which only sells from a fixed location or only manufactures alarm systems, unless such business also services, installs, monitors or responds to alarm systems at the protected premises.

  4. Direct Dial Device Alarm System. A "direct dial device alarm system" means an alarm system used with a device which is connected to a telephone line, and upon activation of the alarm system, automatically dials a predetermined telephone number and transmits a message or signal indicating a need for emergency service.

  5. Disturbance Alarm System. "Disturbance alarm system" means an alarm system signaling the existence of an act amounting to a breach of the public peace at the time of alarm activation.

  6. Monitored perimeter security fence system. "Monitored perimeter security fence system" means a perimeter alarm system with an assembly of battery-powered equipment, including but not limited to: a monitored alarm device and energizer that is intended to periodically deliver pulses to the security fence, a battery charging device used exclusively to charge the system's battery, and other integrated components.

  3. Fire alarm systems.

"Alarm user" means any person who owns, leases, rents or otherwise controls the installation, maintenance or use of an alarm system in any manner in any building, structure or facility wherein an alarm system is maintained within the city.
