From a City of Alameda press release:
The City of Alameda will be testing the CodeRED Emergency Notification System on Wednesday, Sept. 19, 2012.
CodeRED is a service used to notify Alamedans of a major emergency event. The system already has most of the city’s traditional land-line phone numbers, and the other contacts – cell phone, email, etc. - of residents who have opted in for the service.
The test will call all these contacts and leave a message that it is only a test. The calls will begin at approximately 11 a.m. and will continue until the emergency database has been completed.
The purpose of the test is to determine how quickly the City can get an emergency message out to the community, and to encourage all Alamedans to opt in to the service by signing up their cell phone numbers and email addresses. This can be done online, via the City of Alameda website at either www.cityofalameda.gov or www.alamedapolice.org.
People without access to the Internet can call 510-337-8535 Tuesday through Friday from 9 a.m. to 4 p.m. and speak with Communications Supervisor Lisa McNiff, who will assist in entering information into the system.
The Alameda Police Department encourages all individuals and businesses to register, especially individuals who have unlisted phone numbers, who have changed their phone number recently, or who use a cellular phone exclusively or have VoIP phones (such as Vonage) as their primary numbers.
