The Navy said it will conduct an operational test of its "Giant Voice" mass notification system at its Wahiawä 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 Wahiawä.

The short announcement will be preceded with the words "test test test," followed by a warning tone and closing 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.
