(KMOV.com) -- Officials with St. Louis County will be re-testing several tornado sirens this week.

One minute tests will be performed between 10 a.m. and 2 p.m. from September 19th to the 24th.  County officials will use dicibel meters to determine of the devices are operating properly.

The sirens to be tested generated multiple calls following the Labor Day test of St. Louis County's new 185 siren system.

“We want to make sure that the sirens in question are performing as they're supposed to,” explained David J. “Duff” Barney, director of the County’s Emergency Communications Commission. "Each of the sirens will be individually tested and evaluated. The sirens are designed to be heard outdoors. If residents can't hear them when they're inside, that doesn't mean the siren is malfunctioning. The County continues to recommend that residents obtain a weather alert radio for indoor notification.”
 
Before the sirens are activated for this week’s test, County staff will broadcast a “This is only a test” announcement from the particular device about to be tested.
 
In an actual emergency, the sirens would wail continuously for three minutes. Their activation serves as an alert that a tornado or tornadoes are approaching the region – and that residents need to immediately take cover.
 
The exception to this is the first Monday of every month, at 11 a.m., at which date and time the sirens are tested.
