Jefferson and Broomfield counties will test their new emergency notification system next week.

Starting at 9 a.m. on February 6, the CodeRED emergency notification system will begin making test calls to residents in Jefferson and Broomfield counties along with portions of Adams and Clear Creek counties.

The counties previously used First Call Network for emergency notifications. However, during the Lower North Fork Fire last year, at least 12 percent of Jefferson County residents in the evacuation zone were not notified.

7NEWS also learned that some of the evacuation notifications went to people more than 30 miles outside the evacuation zone.

The new CodeRED system may be used to notify residents of evacuation notices, bio-terrorism alerts, boil water notices, missing child reports and severe weather.

Residents of Jefferson and Broomfield counties may register their landlines, cell phones and email addresses with CodeRed on the company's website.

Important note: Jefferson County & Broomfield County residents who have previously registered their phone numbers must re-register under the new notification system to make certain their information is correct.
