Summary
Building and vehicle burglar alarms in Linden must shut off within five minutes of continuous sound or 15 minutes of intermittent sound once triggered. An alarm that runs longer violates the city's Model Noise Ordinance regardless of decibel level.
e. All interior and exterior burglar alarms of a building or motor vehicle must be activated in such a manner that the burglar alarm terminates its operation within five minutes for continuous airborne sound and 15 minutes for intermittent sound after it has been activated. At all other times the limits set forth in Tables I, II or III do not apply.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: rev 4586096; v16 updated 2025-12-16; through 12-16-2025).
Full Breakdown
9e of Linden's Model Noise Ordinance, effective March 18, 2025 under Ordinance No. 69-3, targets alarms specifically rather than folding them into the general decibel tables. All interior and exterior burglar alarms of a building or motor vehicle must be activated so that the alarm terminates its operation within five minutes for continuous airborne sound and 15 minutes for intermittent sound after activation. The decibel ceilings in Tables I, II and III do not apply to alarms at all, meaning the rule is purely about duration: an alarm can be loud, but it cannot keep sounding past the five- or fifteen-minute cutoff.
This distinguishes car and burglar alarms from the ordinance's other restricted uses, such as portable sound devices or vehicle stereos, which are policed by audibility distance instead. 11. Property and vehicle owners bear responsibility for a malfunctioning alarm even if a third party set it off, since the section is written against the alarm's operation rather than any particular person's conduct.
Violations & Fines
A burglar alarm that fails to terminate within the five- or fifteen-minute limit is a violation of § 3-2.9e regardless of who triggered it. First offenses draw a Notice of Violation; a non-minor or repeat violation carries a civil penalty of up to $2,000 under N.J.S.A. 40:49-5, with each additional day of continued sounding treated as a separate offense.
