Y‑12 Public Warning Siren System being replaced, tested this month

Posted: September 4, 2012 - 1:08pm

The Y‑12 Public Warning Siren System (PWSS) located around the Oak Ridge area is being replaced this month with a test of the new system to follow. A private contractor will begin replacement of the electronic sirens today with anticipated completion of the replacement Sept. 14. During this time, workers will be removing old sirens and installing new equipment at various siren locations within Oak Ridge.

As part of the replacement, Y‑12 will be sounding the PWSS sirens at noon Sept. 26 in order to test the operation of the new sirens. Remember, the siren sounding is only part of a test of the siren system.

The Y‑12 PWSS is the combination of siren assemblies that provide a coordinated emergency alarm activation to alert the public of site emergencies. The system is composed of 22 electronic sirens and provides coverage for the immediate notification zone that extends out two miles from the complex.

The new sirens being installed are different models of the current sirens installed in the late 1980’s. Y‑12 initiated an engineering study that indicated that Y‑12 could reduce the siren locations from 22 to 12 by implementing the new mechanical sirens which would provide the same coverage area with increased reliability and efficiency.

The siren tests to be held Sept. 26 ensure that the public, Y‑12 employees and the environment would be protected in the event of an actual emergency at the Y‑12 National Security Complex.
