Summary
Lake Havasu City's alarm chapter does not reach an ordinary car alarm. Section 8.12.040 states that Chapter 8.12's rules "are not applicable to audible alarms affixed to motorized vehicles or watercraft unless the vehicle alarm is connected to a central monitoring system," so a car alarm that just sounds a horn or siren locally sits outside the city's alarm-permitting, false-alarm-reporting and misdemeanor rules that apply to home and business systems.
§ 8.12.010 PURPOSE. ... The purpose of this chapter is to provide standards and regulations for various types of alarms of intrusions, burglary, robbery, fire and other emergency alarm devices, whether by direct line, radio, telephone or other means that require response thereto by the Police Department, Fire Department, or other municipal departments within the city, and to provide for punishment for violations of this chapter. ... § 8.12.040 VEHICLE AND WATERCRAFT ALARMS EXCEPTED. The provisions of this chapter are not applicable to audible alarms affixed to motorized vehicles or watercraft unless the vehicle alarm is connected to a central monitoring system. ... § 8.12.120 VIOLATION—NOTICE—PENALTY. Violations of this chapter may be prosecuted in the same manner as any other misdemeanor.
Full Breakdown
Chapter 8.12 exists, per Section 8.12.010, to set standards for alarms that draw a response from the Police Department, Fire Department, or other city departments, and to punish violations of those standards; Section 8.12.020 recites the Council's findings that false alarms waste manpower and endanger officers. Within that framework, Section 8.12.040 specifically excepts vehicle and watercraft alarms from every other requirement in the chapter, including the direct-dial telephone device rule in Section 8.12.050, the audible-alarm posting and 15-minute reset requirement in Section 8.12.060, the false-alarm written-report duty in Section 8.12.080, the ban on intentionally triggering a false alarm in Section 8.12.090, and the misdemeanor penalty and 10-day correction notice in Section 8.12.120.
That exemption lifts only if the vehicle alarm is wired to a central monitoring system, at which point it is treated exactly like a monitored home or business alarm and becomes subject to those same reporting and penalty provisions. Separately, the city's noise chapter, Chapter 9.30, lists specific "special noise sources" in Section 9.30.060, naming amplified sound reproduction devices, sound trucks and loudspeakers, motor vehicle repair noise, noise near schools, churches and hospitals, and watercraft noise; a car alarm is not among the enumerated special sources there, so a repeatedly sounding alarm would have to be measured against the general decibel limits in Section 9.30.050 to be cited as a noise nuisance on that separate theory.
Violations & Fines
A standard, non-monitored car alarm carries no violation under Chapter 8.12 because Section 8.12.040 excludes it outright. If the alarm is wired to a central monitoring system, it loses that exemption and becomes subject to Section 8.12.120's rule that a first violation of the false-alarm-report duty (Section 8.12.080) or the intentional-false-alarm ban (Section 8.12.090) draws a written notice with 10 days to correct the cause, with continued noncompliance prosecuted as a misdemeanor in the same manner as any other misdemeanor.
