The tests will be conducted on the first Mondays.
Fort Detrick says it will test its Early Warning System the first Monday of each month. Those tests began on May 7th, 2012.
The local military installation says the tests will alert the community to different sounds and their meanings, and it's important for personnel to learn what these sounds mean in case the siren is activated.
The Office of Emergency Management for the US Army Garrison at Fort Detrick says it will keep the public informed about updates, changes and overall issues regarding the Early Warning System.
