Here's a monthly test of the last EOWS 1212 on O'ahu! This siren is located on the east side of O'ahu at He'eia neighborhood park, in my hometown city of Kaneohe. It was upgraded with an UltraVoice many years ago, and is set to dual tone. This particular unit has a very dominant low tone (850hz). It still bears it's original civil defense yellow paint scheme, and retained it's original solar panel from the SiraTone controls! The old radio antennas are no longer used, all Hawai'i sirens now use satellite/cellular activation. A fully up to date map of all sirens on O'ahu is available at oahusirens.com
