About The Warning System

The City of Ovilla All Hazard Community warning System is a dual component system. The specifically designed system for Ovilla provides extensive coverage for the city with the strategically placed siren. Ovilla's low power 790 AM radio station allows the city to communicate exactly what the event is when the siren is sounding. Ovilla's All Hazard Warning Siren manufactured by Federal Signal Corp. has been installed world wide and continues to be a leader in notification of the general public. The siren is mounted on a galvanized metal pole anchored in engineered concrete footings. The siren has four unique tones it can broadcast. The siren is radio activated by specially trained personnel of the Ovilla Fire Department. The system includes a low power AM broadcast station. The station will be used to broadcast emergency information announcements when the need arises, and during normal operations it will broadcast community service announcements. Tune to 790 AM to hear Ovilla Information Radio.

Scheduled Test Times

The scheduled test times nationwide for sounding the siren are on the first Wednesday of every month at 2pm. In Ovilla, we will also test on the first Saturday of every month at 2pm. Ovilla's warning siren is capable of creating more than just one alert tone. In an effort to lessen any chance of confustion, only one tone will be used to notify the citizenry of an emergency. The tone was chosen because it does NOT sound like an emergency vehicle siren. There will be occasions when the siren test will be done using the other alert tones that the system is capable of broadcasting. In the months that these tones are used, there will be an announcement on "Ovilla Information Radio" to inform the citizens.

If The Siren Sounds & An Emergency Exits

When you hear the siren sounding, you should immediately take cover and tune to 790 AM "Ovilla Information Radio" Ovilla's radio station will be used to inform all citizens in the area of the proper actions to take. It is very important that you have a battery powered radio pre-tuned to 790 AM so you will not have to do this during a real emergency. "Ovilla Information Radio" will announce the nature of the emergency on the air when the siren begins to sound. In addition, this announcement will also inform you of the proper actions to take. If you are in a vehicle and traveling through Ovilla and you hear the siren sounding, you should tune your vehicle's radio to 790 AM.

When Thunderstorms Approach

  • If you can hear thunder, you are close enough to the storm to be struck by lighting, go to a safe location immediately.
  • Get out of boats and away from water.
  • Telephone lines and metal pipes can conduct electricity. Use telephones only in an emergency.
  • Do not take a bath or a shower.
  • Turn off air conditioners, power surges from lightning can overload the compressors.
If Caught Outdoors

  • Find a place away from trees, fences, and poles.
  • If in the woods, take shelter under the smaller trees.
  • If you feel your skin tingle or your hair stand on end, squat low to the ground or on the balls of your feet. Place your hands on your knees with your head between them. Make yourself the smallest target possible, and minimize your contact with the ground.
If A Tornado Is Approaching Or The Siren Sounds
