In civil defense sirens, the ATI High-Power Speaker Station (HPSS),[1] by American Signal Corporation (ASC) known as the ASC E-Class, is an electronic outdoor warning siren manufactured by Acoustic Technology, Inc (ATI) that is used to alert citizens of air raids, and natural disasters.
Systems
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 have 4 speakers and the HPSS32 have 8 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. ATI also sold rotational units of the HPSS16, and HPSS32, called the "HPSS16R" and "HPSS32R", that are now discontinued.
