Monthly test of this interesting DSA, located near the Tantalus lookout high above Manoa Valley. It replaced a Thunderbolt 1000T that was mounted on an H platform. This siren is technically doing double duty, partially picking up the slack from a now removed Thunderbolt which was previously located by University of Hawaii. It covers a large area, firing down the mountain into the surrounding areas. The DSA is using UltraVoice controls, & is set to 850/1020Hz dual tone (of course). Enjoy!
