The ATI Soundblaster HPSS (high-power speaker station) is an electronic outdoor warning system manufactured by Acoustic Technology, Inc (ATI) that is used to alert the surrounding populace of tornadoes, hurricanes, severe thunderstorms, fires and so on. The recent HPSS systems use high-powered electronic speakers, which can be independently arranged to provide directional or omnidirectional coverage, depending on installation. The HPSS16 provides up to 1600 watts of continuous power to drive up to four 400-watt speaker units, whereas the larger 3200-watt HPSS32 can drive up to eight 400-watt speakers. Like other electronic outdoor warning systems (such as Federal Signal's Modulator, for example), they can also be used as public announcement (PA) systems, and can play a number of programmed tones. Options include solar-powered operation and pre-recorded voice messages. Sometimes these high-powered speakers play the Westminster Chime. ==Areas known to use HPSS systems== *San Francisco, California - This system is unique, in that it features the sound of the decommissioned Federal Signal STL-10 sirens that the HPSS units replaced *Casitas Dam, Ventura, California (This system is unique, in that they look like the Federal Signal Directional Speaker Array (DSA) sirens), but can have 7–8 speakers per stack, and gray caps on the speaker cones). *Indian Point Energy Center, New York *Owasso, Oklahoma - System of sixteen HPSS32 sirens. * Israel has 3100 sirens as a part of its warning system, and 300 of them are HPSS32 sirens. * Sedgwick County, Kansas 27 ATI HPSS32 units are part of the system's 150 sirens. * Frisco, Texas ATI HPSS32 units. * Fort Riley, Kansas 2 ATI HPSS16 units. * Del City, Oklahoma 8 ATI HPSS16 units.
