Naval Magazine Indian Island mass notification system upgrades

03/06/19 09:00 AM

PORT HADLOCK, Wash., -  Naval Magazine Indian Island will be upgrading and testing the installation’s mass notification system, known as Giant Voice, March 19-20.

The outdoor speaker system is used to broadcast important base announcements and emergency notifications.

From 8 a.m. to 4 p.m. on those days, installation personnel and residents living in the communities surrounding Indian Island will hear sounds, including voice announcements, sirens, distinctive tones and static noise produced from loudspeaker towers.

Testing will occur at one- to one-and-a-half-minute intervals within 10-minute periods. Volume intensities may vary, with the duration of higher volume sounds being shorter than lower sounds.

These upgrades enhance the Navy’s ability to immediately communicate important information during emergencies to military personnel and their families, and civilian employees and contractors working on Navy property.

Naval Magazine Indian Island intends to reduce the impact of this system upgrade to neighboring communities where possible, while maintaining the ability to meet mass warning notification system requirements.

NMII thanks the community for their continued support and understanding.
