Summary
El Monte's Alarm Systems ordinance expressly excludes vehicle alarms from its permit and false-alarm-fee system: EMMC 5.102.010 defines 'alarm system' to exclude 'alarms used in connection with and installed in motor vehicles,' so a car alarm doesn't need a police-issued permit, leaving the general noise-disturbance prohibition in 8.36.080 as the only tool against an alarm that won't stop.
"Alarm system" means any mechanical or electrical device or combination thereof which is designated for the detection of an unauthorized entry on or into any building, place, or premises, or for alerting others of the commission of an unlawful act, or both, or for alerting others of any other emergency situation and which emits a sound or transmits a signal or message. ...Not included in this definition are: 1.Auxiliary devices installed by a telephone or utility company to protect telephone or utility company systems that might be damaged or destroyed;2.Alarms used in connection with and installed in motor vehicles.
