Citizen Alert Emergency Notification System

Our citizen alert emergency notification system, powered by everbridge, will allow the City of Duncanville to send informational messages and emergency alerts about situations as they occur. Alerts can be received on multiple devices such as home phone, mobile device, e-mail, and more.


Sign up with Everbridge to receive text alerts directly to your phone.

City of Duncanville Citizen Alert

We have launched a new Mass Notification service that allows us to alert you. You opt-in to enter your contact information and subscribe to notification you care about based on your location. The information you provide is protected and will not be used for any other purpose.

How It Works

When we issue a notification about a potential safety hazard or concern, you will receive a message on the voice or text communication methods that you have registered. If requested for the notification, you can confirm that you have received the message and you will not be contacted by any subsequent methods regarding that particular notification. If you do not confirm, the system will continue to attempt to reach you at all of the contact paths that you have registered.

Sign up for Notifications

Create an account and add your contact and location information into the Mass Notification system. All information you provide will be kept strictly confidential.


Stop Receiving Notifications

You can stop receiving at any time by removing your contact information from your profile.

For more information, please contact Duncanville Fire Department at (972) 780-4919.

Because we switched systems, residents currently registered with the City’s prior emergency notification system, CodeRED, will have to re-register with Everbridge in order to receive future emergency notifications.

Outdoor Warning Sirens

Duncanville’s outdoor warning siren system consists of eight sirens that can be activated to warn the public of an emergency situation such as a hazardous materials emergency, evacuation, or severe weather warnings.

The outdoor warning siren system is tested on the first Wednesdays of each month.

Early Warning Siren System

The City of Duncanville’s early warning siren system consists of eight outdoor sirens strategically located throughout the city as a warning device to alert citizens outdoors of imminent severe weather. These sirens may be activated individually or in small groups for a localized emergency, or they may all be activated simultaneously for a city-wide weather warning.

While the warning siren system is an effective method of outdoor notification, the City of Duncanville highly recommends each home and business have other means to receive warnings and notifications. Warning and notification can be received by monitoring the following:

  • NOAA National Weather Service Radio
  • Local television and radio stations
  • Internet
  • Weather subscription services
  • Monitoring sky conditions
  • Everbridge Emergency Notification Alerts

If you are outside when the sirens activate go inside and seek shelter immediately. Tune into a local, television or radio station for instructions and severe weather information. It is also recommended you purchase a weather radio to keep in your home.

Go to a pre-designated safe area or to an interior room with few or no windows. Put as many walls as possible between you and the outside. Protect yourself by getting under a heavy table or covering yourself with some sort of thick padding. Use your arms to cover your head and neck to protect from flying and falling debris.

Weather permitting, the outdoor warning system is tested the first Wednesday of each month at 2:00 PM. Testing may be delayed if storms are in the area.
