A federal test of the National Emergency Alert System will result in a test message on all consumer cell phones next week.

The test is scheduled to begin at approximately 2:20 p.m. on Wednesday, Oct. 4.

It will include both Wireless Emergency Alerts to each consumer cell phone as well as an Emergency Alert System test over television and radio.

According to the Federal Emergency Management Agency, this will be the second test to all cellular devices. If the test has to be delayed, it will occur on Oct. 11.

“The purpose of the Oct. 4 test is to ensure that the systems continue to be effective means of warning the public about emergencies, particularly those on the national level,” the agency said in a statement.

This is the message that you should see next week: “THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed.”

All devices, assuming you’re within range of service and your provider participates, should only receive the message once.

Warren County Public Safety Director Ken McCorrison said the message will display “more like an Amber Alert than a text message.”

According to FEMA, the alert will be accompanied by a “unique tone and vibration.”

Alerts that are part of this system are set by local, state or federal agencies through a system to “participating wireless providers which deliver the alerts to compatible handsets in geo-targeted areas.”

The Emergency Alert System portion of the test on radio and TV will last about one minute and the message “will be similar to the regular monthly EAS test messages with which the public is familiar,” according to FEMA.

It will state “This is a nationwide test of the Emergency Alert System, issued by the Federal Emergency Management Agency, covering the United States from 14:20 to 14:50 hours ET. This is only a test. No action is required by the public.”
