TL/DR: This wednesday (November 28, 2018) at 1:55pm a test of the public emergency alerting system will take place.
This is the second test this year of the Alert Ready system which includes cellphones.
The Alert Ready system allows emergency management officials to send out public alerts in times of emergency. Participants in the national system include private and public broadcasters, cellphone service providers and government organizations.
The Emergency Management Office regularly tests components of the public alerting system before an actual emergency occurs. Tests of the system create awareness of Alert Ready and how it works on television, radio and wireless.
Not everyone received the alert on their mobile devices during the test in May for a variety of reasons, including device compatibility, settings and connection to a network. Nova Scotians who do not receive the alert Nov. 28 are encouraged to follow up with their service provider.
The test begins with a loud alert sound on radio, television and compatible cellphones. The sound is followed by a spoken message on television and radio and a text on television and cellphone screens. If a cellphone is in silent mode, there will be no sound but a message will be displayed and the phone may vibrate. If it is switched off it will not receive an emergency alert.
