St. Louis, MO. – False alarms are down in St. Louis.
That's according to the city's Public Safety department which credits a law passed last year.
The new law requires businesses and homeowners to register their alarm systems with the city. After too many false alarms, owners may be fined.
Public Safety director Sam Simon says about 20,000 alarms are now registered.
"This thing's not based on revenue, it's not based on fines, necessarily," Simon said. "It's just based on organization and some kind of administration of what has been traditionally, historically in the City a problem."
The new law also makes an exception so people won't be fined if their alarm goes off because of a power outage or bad weather.
