Summary
Vehicle and building burglar alarms must silence themselves within 5 minutes of continuous airborne sound or 15 minutes of intermittent sound after activation, and the decibel tables do not otherwise apply to them.
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 Table 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 4984352; v35 updated 2026-06-16; through 06-16-2026).
Full Breakdown
' The section closes by stating that at all other times, the Table I, II, and III decibel limits do not apply to alarms, meaning enforcement turns entirely on the shutoff timer rather than a measured sound level. Because this provision sits inside § 311-9, 'Restricted uses and activities,' it is enforced by the same Noise Control Officers and Noise Control Investigators who administer the rest of Chapter 311, not by a separate false-alarm ordinance. A car alarm that resets and re-triggers repeatedly could also draw a complaint under the general nuisance provisions in Chapter 317 if it disturbs a resident's peace, comfort, and repose, but § 311-9E's five/fifteen-minute cutoff is the specific standard for the alarm itself.
Violations & Fines
A violation of the alarm shutoff timer is deemed purposeful and therefore a nonminor violation of Chapter 311 under § 311-10's classification standard applied elsewhere in the chapter; nonminor violations draw a notice of penalty assessment with a civil penalty of up to $2,000 per offense under N.J.S.A. 40:49-5, and each day of continuation is a separate offense. The recipient may request a municipal court hearing to contest the penalty.
