ATI HPSS
The ATI Soundblaster HPSS (High-Power Speaker Station) is an electronic outdoor warning siren manufactured by Acoustic Technology, Inc (ATI) that is used to alert citizens 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. They can also be used as public announcement (PA) systems, and can play a number of programmed tones. Options include solar-powered operation pre-recorded voice messages, and units with rotational capabilities.
