Lexington County residents will hear a lot of sirens Friday evening.

But it's no cause for alarm.

Lexington County announced all emergency services and law enforcement vehicles throughout the county will sound their sirens at 7 pm April 3.

The county posted the announcement on its Facebook page:
"As our community rallies together to support each other and beat COVID-19, we want all of our residents to know that your emergency responders are here to continue providing the highest levels of service possible.

"To ensure you know that we are here 24 hours a day, seven days a week, 365 days a year, all emergency services and law enforcement vehicles throughout the County that are not in the process of responding to a call will, from a stationary location, sound their siren on Friday, April 3, at 7 p.m.

"This is done through a strong partnership between County responders and our Municipal partners.

"Thank you for your continuing patience and support of your first responders! We could not do what we do without you, the amazing residents of our County.

"If you call 911, we will come."
