Sounding or permitting the sounding of any exterior burglar alarm or any motor vehicle burglar alarm unless such alarm is automatically terminated within 15 minutes of activation.

Full Breakdown
Henderson's noise control chapter bars sounding or permitting the sounding of an exterior burglar alarm or a motor vehicle burglar alarm that isn't set to terminate automatically within 15 minutes of activation. The code goes further than the timeout: the owner or person responsible for the alarm is in violation if it activates more than twice in a calendar month, even when the trigger was false or accidental. The provision sits in HMC Chapter 8.84's 'Emergency signaling devices' subsection alongside stationary fire, burglar and civil-defense alarms, and any violation of the chapter is a misdemeanor under HMC § 8.84.050.
Violations & Fines
A misdemeanor under HMC § 8.84.050. An alarm that doesn't auto-terminate within 15 minutes, or that false-triggers more than twice in a calendar month, puts the owner in violation.
