"It was like two loud sirens," said Cisco resident Lindsey Elliot.
Yet not everyone knows what they mean.
" I don't know, i didn't even know what they were for when i first heard them," said Elliott.
Others, however, know its time to take cover.
"Go to the lowest point , say the bottom of a tank if its empty or like a gutter," said Eastland resident Janie Carrion
That's why the Eastland County Fire Deparment wants to make sure they work.
At least once a year they test out their severe weather warning system to ensure its ready for a situation like the one in Dallas just days ago.
But its not just for tornadoes.
"A tornado has its own sound, which is the siren that everybody's used to, large hail and high winds," said firefighter David Branch.
The firefighters make sure to listen to national weather service updates and check computers for live satellite images of weather activity.
They're able to send out text messages and emails to a number of registered residents who want warnings other than the sirens.
There are a total of five severe weather warning sirens in Eastland.
Firefighters say they're strategically placed in neighborhoods or on top of buildings like this one so that as many people can hear and know its time to take cover.
"We go off of the national weather service and they'll tell us when to go out to do storm spotting and our volunteers have all gone through storm spotting class," said Branch.
Firefighters check on any that aren't working properly.
They say routine practices like this one are essential preparation for the real deal.
"We want everyone to be safe that's the reason the city spent the money on the sirens and we have them there so that if there is an emergency we can alert the public," said Branch.
