Crystal Brown lives near one of three sirens in the city. She said, "They were extremely loud out here."
It's music to her ears after a funnel cloud touched down in her yard just two years ago.
Brown said, "It was in the middle of the night and it came through and tore the high school gym up. It landed in our front yard. I had a one-year-old and a three-year-old."
Sixteen electronic speakers are sitting in the sky on standby. They are ready to alert the city.
Centerton Mayor Bill Edwards said, "Benton County Emergency Management Communications sets them off. They have the codes programmed into the radio and if there is a tornado warning, they push a button and off they go."
Brown said, "Because they were loud enough I think it would actually wake me up." She said the city has waited years for these sirens.
Edwards said, "We did try them back in 2005. The cost was three times more than one siren costs today."
"If your sirens are in another town, you can't hear them and how are you supposed to know to get to safety," Brown said.
Now that she knows the system is in place, it's putting her and her kids at ease.
Brown said, "They saw them and they watched them put them up so they are kind of excited to know that they are going to be okay."
Edwards said, "Today we did a full test with Benton County and it worked just fine and I'm happy for that."
Edwards said even if alarm activation fails, the city can set them off from anywhere in town.
