The public is reminded that DDM generally tests the system on the fourth Friday of the month. While no action is required during the test, it is a good opportunity to test emergency procedures wherever you are.
Remember, activation of the emergency sirens is a signal to residents to tune in to local radio or check the DDM website, app or social media accounts for detailed safety information. During a test, equipment sounds for 60 seconds, but in an emergency they will sound continuously.
