Summary
Emergency sirens and vehicle alarms are otherwise excluded from Hartford's noise limits, but Code § 23-3(e)(3) carves out one exception: a burglar alarm on a motor vehicle that doesn't terminate within 10 minutes of activation is unlawful. A building alarm gets a longer 30-minute grace period, and repeat false activations from a poorly maintained system lose the exclusion entirely.
(e)Exclusions: These levels shall not apply to noise emitted by or related to: ...(3)Any siren, whistle, or bell lawfully used by emergency vehicles or any other alarm systems used in an emergency situation; provided, however, that burglar alarms on motor vehicles not terminating within ten (10) minutes or on buildings not terminating within thirty (30) minutes after being activated shall be unlawful. Notwithstanding the foregoing, repetitive activation of any alarm system due to malfunction or lack of proper maintenance shall not be excluded;
Full Breakdown
" That broad exclusion for alarm systems carries a specific proviso for vehicles: a burglar alarm on a motor vehicle must terminate within 10 minutes of being triggered, or the ongoing noise becomes unlawful rather than excluded. A building alarm gets three times as long, 30 minutes, before it loses the exclusion. The section adds a maintenance condition that applies to both: "repetitive activation of any alarm system due to malfunction or lack of proper maintenance shall not be excluded," so an owner whose car alarm keeps false-triggering cannot rely on the general emergency-alarm exclusion even if each individual activation self-terminates within 10 minutes.
Because § 23-3(c) treats any noise plainly audible off the vehicle's location as prima facie evidence of a violation without a meter reading, officers responding to a neighbor complaint about a car alarm running past the 10-minute mark, or one that keeps going off, can document the violation directly. 00, up to 25 days in jail, and community service, with the standard § 1-5 appeal rights unavailable for this chapter.
Violations & Fines
A vehicle burglar alarm that runs longer than 10 minutes after activation, or one that repeatedly false-triggers from malfunction or poor maintenance, loses the emergency-alarm exclusion and is prosecuted under § 23-8: community court, a fine up to $90.00, up to 25 days in jail, and community service.
