SCHOFIELD BARRACKS, Hawaii — U.S. Army Garrison Hawaii will be upgrading and testing its mass warning notification system June 20-28. Existing sirens will be modified, and in some areas, new sirens will be installed. As a part of the upgrade, all sirens across Army installations will be tested.

Employees, residents and community members off the installation may hear the sirens and pre-recorded voice messages during the testing period. During the installation and upgrade, June 20-28, each siren may produce a few quick tones.

The following is a breakdown of the siren upgrades and testing:

  • 22 June Aliamanu, Red Hill, Ft. Shafter, Ft. Shafter Flats, Tripler Army Medical Center
  • 23 June East Range, Helemano Military Reservation and Wheeler Army Airfield
  • 24 June Field Station Kunia and Schofield Barracks (possible extra dates 27-28 June)
Residents and community members can expect to hear pre-recorded verbal messages, bugle calls, and traditional siren wails. The entire test will take approximately five minutes per siren, and the tests will take place between 8 a.m.-4:30 p.m. on the days above.

After the siren upgrades, daily bugle calls will continue on Fort Shafter, Fort Shafter Flats and Schofield Barracks, and will begin at Tripler Army Medical Center and Wheeler Army Airfield.
