WESTPORT — The town has replaced the emergency notification system it has used since 2009, and urges residents not to assume they are registered.

The Westport fire have partnered with Nixle to implement its community notification system which can geographically located users to alert them of issues. Nixle alerts allow information to be sent via text, email, voice, web, and social media in an instant.

“This will alert residents in real-time for localized emergency situations and relevant community advisories,” read a statement from the fire department. “This system will improve the safety of all our residents. The Westport Police Department has been using Nixle to provide traffic advisories for the past four years and it has proven to be reliable and easy-to-use.”

Residents can customize their alert settings by going to www.nixle.com and creating a profile.

Nixle will be replacing the CodeRED emergency notification system Westport has used since 2009. No information was provided on the cost difference between the two products.

Officials say residents and business owners should not assume their number is registered and should take the time to register.

Nixle is partnered with the National Center for Missing and Exploited Children, the National Blue Alert Network, and Google for unmatched reach.
