The Navy says it will conduct an operational test of its “Giant Voice” mass notification system at its Wahiawa annex today at 1 p.m. The announcement on the public address system will be audible to those who live or work near Naval Computer and Telecommunications Area Master Station Pacific in Wahiawa.

The short announcement will be preceded with the words “test test test,” followed by a warning tone and then close with “test test test.”
The system provides base-wide siren signals and prerecorded and live voice messages for emergency situations. Routine tests are periodically held.
