ATI HPSS
In civil defense sirens, the ATI High-Power Speaker Station (HPSS),[1] 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
HPSS systems use high-powered electronic speakers, which can be independently arranged to provide directional, omnidirectional, and formerly rotational coverage. The HPSS16 has four speakers, while the HPSS32 has eight speakers. The HPSS16R and HPSS32R are former rotational models that were discontinued. They can be used as public address (PA) systems and can play programmed tones. Options include solar-powered operation and pre-recorded voice messages.
