Tornado & Civil Defense Siren Maintenance & Repair

Outdoor warning sirens sound when the National Weather Service (NWS) notices a life-threatening event is occurring, such as hail, tornado, or extreme wind, but reasons for sirens sounding varies by jurisdiction.

TLS is proud to be the only company in Oklahoma to be certified to perform Civil Defense Siren maintenance and repairs. 

Maintenance entails, among other things, the following:

  • Examining the siren’s overall condition and ensuring that it is free of obstructions.
  • Sound performance and quality, including tone and voice, are evaluated.
  • Tighten any loose wire connections within the control box.
  • Any vandalism, lightning, or power surge damage will be repaired.
  • If installed, replenishing the battery’s water levels as needed.

You can lessen the danger of failure by repairing any tornado sirens that aren’t working.

Allow TLS to maintain your sirens on a regular basis, and you can be assured that your emergency management system will provide appropriate warning to your residents. We’ll also test sirens on a regular basis and fix problems before they cause complete failure and higher expenditures.

TLS can assist you in identifying any problems with your Civil Defense sirens and may provide information to ensure that the sirens are operating. We can also help if you need a new siren, controls, or other emergency management solutions.

Tornado Safety Video Tips

Tornadoes are the world’s most violent atmospheric storms. They are narrow, violently rotating columns of air extending from the base of a thunderstorm to the ground, and they are sometimes hard or impossible to see.

Tornado Safety

  • Get inside a well-constructed building and seek shelter if a tornado is nearby. Flying debris is the greatest danger.
  • The safest place to be is a storm shelter built to FEMA guidelines and ICC 500 standards, or a basement. 
  • If there’s no storm shelter, get to the innermost room, hallway or closet on the lowest level of the building. Put as many walls between you and the outside as possible, and stay away from windows and doors. Most houses provide life-saving protection from 98 percent of tornadoes in Oklahoma and Arkansas.
  • Wear a helmet and/or use pillows, cushions and thick blankets for additional protection. Wear sturdy shoes that will protect your feet if you have to walk through debris.
  • Vehicles are unsafe in tornades. Many deaths are attributed to being inside a vehicle when a tornado strikes. If you’re driving when a tornado threat is nearby, get to the closest well-constructed building to take shelter. Never attempt to outrun a tornado by driving.
  • Mobile homes are unsafe in tornadoes. Have a plan to get to the nearest well-constructed building to take shelter.
  • If you have a storm shelter at your home, register it with your municipality so emergency crews know where to find you in a disaster.
  • Search to see if your municipality has public tornado shelters.  

Have at least 3 ways to get weather information

Wherever you are during a severe weather threat, it is best to have at least three ways to get information about the weather.

  1. One method should work without electricity, 
  2. One without batteries, 
  3. One without a cellular or wifi connection.

Many weather radios have hand-powered cranks for us if you don’t have power or batteries. They’re available to buy locally at many general merchandise stores, and online.

The best sources to get weather related warnings are in this order.

  1. Smartphone or tablet app, like the Emergency app from the American Red Cross for iOS (Apple) and Android devices. 
  2. Outdoor warning sirens if you are outdoors.

Although the above should not be your only sources for weather warnings, the following can be used as secondary sources with the primary sources listed above:

  1. Local television, radio and multimedia news organizations, on traditional (TV and radio) and streaming platforms.
  2. The local National Weather Service website, mobile website, and Twitter account. 
  3. Your city’s Twitter (now called X) and Facebook accounts.


Outdoor Warning Sirens – FAQS

  • Where can you hear sirens?

    Although sirens are frequently heard indoors, their primary purpose is to warn individuals outside that a tornado is approaching. Even if you are used to hearing a siren inside your home, you may not hear one during a thunderstorm. If necessary, look for your municipality’s Accessible Hazard Alert System online to receive alerts in American Sign Language as well as English voice and text.

  • When are sirens tested?

    Every weekday, sirens in most Oklahoma towns and cities are silently tested, but this may vary depending on where you live. If there are no severe weather concerns, audible siren testing is conducted every Saturday at noon.

  • Why is it important to maintain Civil Defense Sirens?

    There are numerous reasons to keep your Civil Defense Sirens’ maintenance up to date. If severe weather strikes and any of your sirens fail, people may be unaware that severe weather is approaching, potentially putting their lives in danger.

    Living in “Tornado Alley,” it’s critical to have your Civil Defense Sirens operational, especially during tornado season with high potential of severe weather. Maintaining your Civil Defense Siren will lessen the likelihood of it failing, boost the safety of your citizens, and reduce the possibility of injuries.
