The Gardena Police Department has enabled Gardena residents to enroll in the online alarm prevention program. This course is entirely online and can be completed from any computer in about 30 minutes. It can be taken whether or not you have caused a false alarm, and there is no charge for the class. The City provides a 50% reduction [$37.50] in assessed false alarm fines for permitted residents on the 4th false alarm upon course completion - once in a 365 day period.
