Summary

A burglar alarm on a vehicle or building in Smithtown must shut off within 15 minutes of activation and cannot run more than 15 minutes in any one-hour period to stay exempt from the noise code's decibel limits.

The noise from a burglar alarm of any building or motor vehicle, provided that such burglar alarm shall terminate its operation within 15 minutes after it has been activated and shall not operate more than 15 minutes in any one-hour period.

Full Breakdown

Town Code § 207-6B(5) exempts the noise from a burglar alarm of any building or motor vehicle from the Table I sound-pressure-level limits, but only on the condition that the alarm terminates its operation within 15 minutes after activation and does not operate more than 15 minutes in any one-hour period. An alarm that keeps sounding past that window loses its exemption and becomes actionable as a noise disturbance under the general prohibitions of § 207-2. Separately, § 207-2B(7) bars sounding any horn, signaling device or alarm, aside from a genuine Vehicle and Traffic Law § 375 danger warning, in a way that produces a harsh or loud sound or repetitive sounds for an unreasonable period so as to create a noise disturbance, which reaches a car alarm that a driver or owner fails to silence.

A 2003 amendment repealed a prior version of the burglar-alarm exception that dealt with signaling devices used in connection with an emergency and renumbered the current 15-minute rule into what is now Subsection B(5).

Violations & Fines

An alarm exceeding the 15-minute limits, or a signaling device that creates a repetitive noise disturbance under § 207-2B(7), is punishable under § 207-7: up to $500 for a first offense, not less than $1,000 for a second, and not less than $1,500 for a third or subsequent offense, with up to 15 days imprisonment possible.

Frequently Asked Questions

How long can a car alarm legally sound in Smithtown?
Section 207-6B(5) exempts a burglar alarm from the decibel limits only if it terminates within 15 minutes of activation and does not operate more than 15 minutes in any one-hour period; beyond that it can be cited as a noise disturbance.
What happens if my car alarm keeps going off repeatedly?
Once it exceeds the 15-minute-per-activation or per-hour limits in § 207-6B(5), the exemption no longer applies, and repetitive sounding can be enforced under § 207-2B(7)'s ban on harsh or repetitive alarm sounds.
Does the alarm exemption require a decibel measurement?
No. The § 207-6B(5) exemption turns on timing, not loudness; a technician's dBA reading is only relevant if the alarm sound is not covered by the exemption and is instead measured against Table I.
