The San Onofre Nuclear Generating Station (SONGS) Sirens are a network of 50 sirens located within a 10-mile radius of the San Onofre Nuclear Generating Station located in San Clemente, California. There are three WPS-2750 sirens located near the plant. However most of them are WPS-2805 , and WPS-2905 and WPS-2906, sirens. These sirens are activated by the three Jurisdictions the sirens are placed in, which is San Juan Capistrano, Dana Point, and San Clemente.
Most sirens run on 435 HZ, but around 2012, some were ungraded to 2030 logic boards and are 560 HZ. This plant used to have Model 120 and STL-10 Sirens, replaced in November 2005.
